WADARC meets at – Lions Hall, 21 Roberts Road, Lancing. BN15 8AR.

THE PAST WEEK

Last Wednesday’s meeting was supposed to be some practical work on antennas, but due to unforeseen circumstances, it had to be called off, so we had Tea and Chat instead. Although there was no actual work on antennas, there were two different antenna analysers available for members to become familiar with. There were reports on the Dayton Hamvention and advice was given on how to attach the steel rope to my new mast winch. Comment was also made on the ill-founded online petition that’s circulating, regarding removing the need for planning permission for Radio Amateurs’ antennas.

RAGCHEW

Winter 2017 edition published – http://www.wadarc.org.uk/ragchew/winter-201718

PROPAGATION

HF:

A glancing blow from a high-speed solar wind stream caused the K-index to rise to three on Wednesday. This was a little unexpected as it came from a polar coronal hole on the Sun that didn’t look like it would impact the Earth. This brought mixed blessings as an initial positive phase saw the maximum usable frequency over 3,000km exceed 18MHz. But conditions soon dropped back and 20 metres became the highest viable band for F-layer propagation.

Sporadic E has been bringing some good short skip to the higher bands so do make the most of it, with the peaks generally around mid-to-late morning and again in the late afternoon and early evening.

The good news is we are seeing some sunspot activity, albeit very weak. At the time of writing there were two small visible regions and another coming around the sun’s limb. Nevertheless, NOAA predicts the solar flux will remain around 70.

Geomagnetic conditions are set to be settled this week, at least until Friday the 1st when NOAA has the K index rising again. This is due to another coronal hole, which may cause unsettled conditions over the weekend of the 2nd and 3rd with a maximum predicted K index of six.

So better HF conditions may occur in the first half of the week, but the weekend might not be the best time for DX. A high-speed solar wind may also not be conducive to stable Sporadic E cloud formation either, although this is an area that needs some more research.

VHF/UHF:

The next week carries on in similar fashion with low pressure close to southern Britain, offering a chance of rain scatter in any showers. The north of the country remains close to high pressure over Scandinavia with a chance of further patches of enhanced tropo across the North Sea.

The southern half of the country will be nearer to low pressure over the continent and will have an enhanced risk of showers, some thundery. This will make rain scatter a possibility for the microwave bands.

Sporadic E is amongst us and hopefully this next week will continue to provide options. However, since jet streams are often implicated in the formation of sporadic E, the news is not so good in that the main Atlantic jet stream is displaced well to the north of Europe.

The main operating rules are to check the clusters and beacons for activity, initially on 10m, but then upwards through 6m to 4m and 2m as the opening develops. Conditions may only happen for brief moments, so keep the overs short with report and locator in case the path fades.

Moon declination is negative this week, and apogee just a week away so losses are approaching their highest and moon windows will be at their shortest. This means low antenna elevations and increasing noise at VHF and UHF.

Beacons often heard in our area:

GB3WSX – IO80QW – 70.007 MHz

FINALÉ

Having already started to get my affairs in order – getting a Will drawn up, then having an impending operation dumped on me at short notice, tends to focus the mind somewhat. Without wishing to be morbid, I’d like to remind all members that WADARC has a ‘policy’ (course of action) should your executors require it. However, you should make it quite clear in your Will that WADARC are to be charged with selling your Amateur Radio equipment on your estate’s behalf and of course mentioned in any donations you may wish to make.

WADARC is mentioned in my Will, is it in yours?

THE PAST WEEK

Last weekend was Mills On The Air when GB0HSM was setup at Salvington Mill. There wasn’t sufficient time to buy a new club laptop and set it up, so Roger, G7VBR’s laptop was dragged into service and with the IC7300 working fine, logging was once again fairly straightforward. Pete, G4LKW reported that many QSOs took place mainly on 80 and 40 metres.

Wednesday’s Tea and Chat did just what it said on the tin, with some discussion regarding Mills On The Air and various other chatterings. There was even some Morse Code practice – well done Ray, keep it up!

Please note: Although there was talk about the forthcoming Foxhunt, it DOES NOT take place NEXT Wednesday, it’s the Wednesday after that – 30th May!

RAGCHEW

Winter 2017 edition published – http://www.wadarc.org.uk/ragchew/winter-201718

PROPAGATION

HF:

Last week continued with zero sunspots after the 13th and a solar flux index of around 70. NOAA had forecast poorer geomagnetic conditions from Thursday, the 17th. The solar wind speed, as measured at the ACE spacecraft, did increase on Thursday morning but the K-index hadn’t got above three by Thursday afternoon.

Overall, HF conditions were average with daytime critical frequencies tending to be in the range 4 to 5MHz. This translates to an F-layer maximum usable frequency over a 3,000km path of about 15-17MHz. This means that the most reliable daytime DX band remains 20 metres, 14MHz.

As we move towards more summer-like ionospheric conditions the higher HF bands are remaining open later. The 30 and sometimes even 20 metre bands are staying open longer after sunset, although 20m is still closing by late evening.

Sporadic E is still bringing some interest to the upper HF bands, particularly 10 metres, but you can see the short-skip effects down to 20 meters as well.

The FT8 frequency of 28.074 MHz is now a good first check point for band openings. The 10m beacons are also worth checking because SR5TDM, a three watt low-power Polish beacon on 28.215MHz, was audible during the week. You can find a 10 and 6m beacon list by searching on the web for G3USF beacons.

Next week, NOAA predicts the solar flux index will remain around 70. A lack of coronal hole activity means the K-index may only reach a maximum of two.

In summary then, it’s more of the same for HF!

VHF/UHF:

The charts show a lot of high pressure over the next week and this means a good chance of some tropo. The best paths will be over the surrounding seas, especially the North Sea at first. There may be a trend for drier air to remove some of the low-level moisture after this weekend, so paths won’t necessarily be good all of the time. The overnight conditions under high pressure can also produce temporary nocturnal lifts over land, but these paths tend to decay quickly after sunrise, when the heating breaks down any surface inversion.

Since it looks like a largely dry spell of weather, there may be a shortage of rain scatter clouds about for the microwave bands. All is not lost and there is some hope that sporadic E will continue to put in an appearance now and again. However, one of the main ingredients, a strong jet stream over Europe, may be hard to find in this fine, settled weather. This means the fall-back option of upper ridge patterns may be the trigger to watch. Check the daily sporadic E blogs on propquest.co.uk to see the current location of jet streams and ridges.

The Moon is past perigee, but losses are still low and will fall as the week progresses. Similarly, declination is falling but still in double figures until Wednesday, so another good week for EME with moon visibility from late morning through to after midnight most days.

FINALÉ

Sometimes on the Thursday morning 40 metre SSB net, reception can be impossible due to high noise levels, unless the required station is quite strong and there’s no QSB. It often pays to use an online SDR in parallel with the K3S. I normally use the Hack Green SDR, but I recognise that it’s a bit too far up country to be sure that my signal may be heard from Shoreham, although it can be an aid to propagation checks if I can hear my transmitted signal coming back from the SDR, which means that I can be heard further up-country.

However, I was searching for an online SDR that’s much closer to home and eventually found one, located at Farnham in Surrey, which although not ideal, is good enough for now. The software and display is different to some of the other SDRs, but works well and is easy to use. Fortunately it also has memory facilities so favourite frequencies can be stored for later recall. Another nice feature is that when you specify a label for your saved memory, it’s displayed on the waterfall, when the memory’s recalled.

Although the SDR is labelled as a Top Band facility, it will also receive 80 and 40 metres. Here’s the link: http://topband.ddns.net:8901/

Online SDRs are particularly useful because their antennas are generally situated in optimum positions away from man-made noise. They do have some limitations such as not being great with handling adjacent strong signals and may suffer dropouts etc., if your Internet connection isn’t good. However, they are a useful tool and can be regarded as a remote receiver on the end of a 100 mile cable to home, with no losses!

THE PAST WEEK

Last Wednesday’s meeting was mainly about preparation for Mills On The Air. The IC7300 is working fine but unfortunately the club’s laptop is fu no longer viable. Although it’s only used for logging, Log4OM has withdrawn support for Windows XP, so it just won’t run without falling over. Fortunately there were sufficient committee members present to form a (committee) quorum, so a quick vote unanimously agreed to purchase a new laptop. Roger, G7VBR will make the purchase with advice on what to buy from Chris, M0VUE. It’s hoped to have everything setup on a Windows 10 machine by the time ‘Mills’ starts tomorrow.

Ron, G3SKI is getting about now and would like WADARC members to visit him at home. Please phone Ron first to arrange a meeting.

Andy, M6RFE is also faring better and has been spotted in his workshop.

My leg, arm and back problems are on-going. More after I see a consultant next Tuesday. Thanks to all members who have helped out/are helping out with meetings and tea.

PROPAGATION

HF:

ARLP019 Propagation de K7RA

Sunspots reappeared this week, after none on April 28 through May 3. Average daily sunspot numbers increased from 3.6 (last week) to 14.6 (May 3-9).

So far in 2018 56% of days were spotless. For all of 2017 the rate was about half or 28%, for the whole year, a total of 104 days. These numbers are according to http://www.spaceweather.com . Seemingly counter-intuitively considering the slight rise in sunspot numbers, yet not unusual, average daily solar flux declined one point from 69.3 to 68.3.

Solar activity continues to decline, and we’ve been expecting (over the past few years) solar minimum to arrive about two years from now in 2020.

But some have suggested that perhaps the decline is currently faster than anticipated. I like to imagine a sooner minima could precede a faster rise in the next cycle! What if the upcoming Cycle 25 echoes Cycle 19? Sorry, no scientific evidence, but I like to dream this could happen.

Cycle 19 was the largest in recorded history, and I would be glad to see another one, just so it isn’t accompanied by a Carrington Event. The Carrington Event happened in September 1859 and produced solar flares so powerful that telegraph offices, connected by long lines acting as antennas, caught fire. But the peak of Cycle 19 happened about 100 years later.

Spaceweather.com reports this week that the American Geophysical Union (agu.org) in a paper published May 10, researchers from the University of Birmingham use Extreme Value Theory to estimate the average time between “Carrington-like flares.”

See https://bit.ly/2G6J2sR

Tough to predict, but they estimate one every 100 years. Of course, this means we are long overdue, but perhaps this is like the gambler’s fallacy: don’t bet on red just because the last five spins of the wheel landed on black:

https://en.wikipedia.org/wiki/Gambler%27s_fallacy

According to http://legacy-www.swpc.noaa.gov/weekly/pdf/prf2227.pdf on page 11, smoothed solar flux numbers around 63 are predicted toward the end of 2019. But when we observe numbers around the last solar minimum (right now I am looking at the 109 days ending on October 9, 2008 as an example) there were numerous consecutive periods of no sunspots (average daily sunspot number during that time was only 1.046) but average daily solar flux was 66.4, several points higher than values predicted for the end of 2019.

These long term predictions are updated about every four weeks, but I have no idea when predictions for 2020 will appear.

Predicted solar flux is 69 on May 11-12, 68 on May 13-15, 67 on May 16-18, 72 on May 19-25, 70 on May 26, 68 on May 27 through June 8, and 70 on June 9, 72 on June 10-21, 70 on June 22 and 68 on June 23-24.

Predicted planetary A index is 8 on May 11, 5 on May 12-16, 12 on May 17-18, 8 on May 19, 5 on May 20-31, then 18, 25, 20, 16, 12 and 8 on June 1-6, 5 on June 7-12, then 42, 12, and 8 on June 13-15 and 5 on June 16-24.

VHF/UHF:

There have been some reasonable tropo conditions recently, but mainly limited to coastal and sea paths. A UK amateur television record-breaking 5.6GHz contact using low power video senders was made last Wednesday, between the Norfolk and Yorkshire coasts, using a shallow surface duct. This can be a relatively-common feature in the summer, but they can be very shallow; climbing the cliffs may just make you too high.

This coming week, with high pressure nearby, there will continue to be options for more tropo, but keep in mind that nocturnal cooling inversions that give some good overnight tropo soon disperse after sunrise. Looking for the high-microwave-band beacons overnight often shows them appearing after a hot day.

Tropo is not guaranteed this week since the high pressure is rather weak and often replaced by shallow areas of low pressure with an attendant risk of thundery showers, giving some possibility of rain scatter on the microwave bands.

The sporadic E season is well under way. We need to look at the location of jet streams within Europe this week, which can influence the location of sporadic E. A north-westerly jet stream over the Pyrenees could help paths to EA and CT. As usual the best advice to capture sporadic E is to remember to check 10m and 6m when you get home from work. Checking beacons, the Reverse Beacon Network and clusters should be your first tasks before having your evening meal!

The Moon reaches perigee, its closest point to Earth, on Thursday and maximum declination on Friday, so it’s a good week for EME.

WADARC meets at – Lions Hall, 21 Roberts Road, Lancing. BN15 8AR.

THE PAST WEEK

Chris (M0VUE) gave a great talk on Wednesday about his travels over land, sand and ‘creme brulee’ from UK to Morocco .. along with some possibly dodgy navigation into Algeria in extreme wipe-out sandstorm conditions! Thank you Chris.

As you probably know Maplin Electronics is closing down. The web site is no longer functioning but the shops are still open for a few more weeks. Some gear is selling off at low prices.
I picked up two ‘cable access kit’ packs. These are ten x 30cm reinforced rods with brass threads to join them together for cable routing in difficult places (A77QW).
I thought they might come in handy for portable antennas experiments – e.g. made up into loops, two could be joined together at right angles to make a support for loop antennas etc.

We heard at the Wed meeting that the ‘Moon Bounce’ talk could not be arranged so next Wednesday will be an on-air night with the IC7300 and we’re interfacing it with the club laptop for logging at Mills On The Air.

In the Propagation section below there is an explanation why 40m is currently a good band to use in the daytime (re. Alan’s recent e-mail about the Thursday ee40m net).
There is also useful info. on the start of the Sporadic E season (“first place to check out will be along the lines of jet streams ….”).

Andy, M6RFE is feeling much better but still has a little way to go.

Good DX to you !
Jonathan, G1EXG

PROPAGATION

Propagation News – 29 April 2018

RSGB | April 27, 2018
Last weekend’s poor HF conditions, which made for a quieter than normal International Marconi Day on the 21st, were largely caused by incoming material from a large solar coronal hole. A lack of sunspots didn’t help either.
The incoming solar wind pushed the K-index up to six at one point, but conditions settled as the week went on. By Thursday the 26th the K-index was down to zero or one.

A small sunspot group pushed the solar flux index to a maximum of 77 and the sunspot number to 34. But even this had declined to 69 and 17 by Thursday.
As a result maximum usable frequencies struggled to exceed 14MHz at times and skip on the lower bands, particularly 40 metres, tended to be longer.
The Space Weather Prediction Center says we might expect another geomagnetic disturbance this weekend due to a high-speed solar wind stream.

But after that, next week’s geomagnetic conditions are predicted to be fairly settled with a maximum K-index of two. NOAA predicts the solar flux index will remain in the low to mid seventies.
One positive is that the lower solar flux means D layer absorption is also weakened. This means 40m is often open to paths around Europe during the day—do take a look at the band as it is often open to France, Germany, Switzerland and Italy, for example, when 20m is largely closed.
Putting this all together, we might expect slightly better daylight HF conditions next week with band openings on 40, 30 and up to 20, with occasional surprises on 17 metres.
We are still seeing a slight uplift in the critical frequency after sunset, and the ionosonde data show that 20 metres may remain open to DX over a 3,000km path until about 21.30 UTC.
As always, these are predictions and you need to get on the air to find out if they come true!

VHF and up

The pressure will remain low close to the British Isles and therefore tropo is unlikely to feature much, other than transient openings around dawn.
With heavy showers and thunderstorms in the forecast, it could be a good spell for rain scatter on the gigahertz bands, so radar sites such as Patrick, TK5EP’s SCP map will be your friend for setting up QSOs.

Sporadic E is coming into its time now, and there have already been some openings across Europe using FT8.
Be prepared for some more traditional openings for CW and SSB signals soon. The earlier FT8 events have been linked to the positions of jet streams, but it’s very hard to be precise, since they happen most days.
For the CW and SSB signal levels it is likely that the first place to check out will be along the lines of jet streams, especially where they intersect with mountain ranges like the Alps and Pyrenees. The upper air forecast charts do show a good deal of jet stream activity over the next week, so it’s time to set up a listening watch on the beacons and clusters.

Moon declination is negative and falling all week, reaching minimum next Saturday. This coincides with apogee, so peak Moon elevations are at a minimum and losses are highest at the same time.
This is a week to check out your antenna and receiver performance using Sun-to-cold-sky noise measurements as the Sun is getting to a good maximum elevation now.

THE PAST WEEK

Despite being a bit damp and windy from time to time, Wednesday’s hilltop meeting seems to have been popular, with over 10 people attending. Please boast about any DX via the Discuss reflector.

Today is the birthday of Samuel Morse who is claimed to be the originator of Morse Code. The unsung hero in the story of Morse Code was Alfred Vail – who pretty much invented the dot-dash code as we know it, as
well as the hand key, but it’s Morse’s name, as owner of the company that paid for it, on the patents. Sic transit Gloria.

Ted, G3EUE has suggested that we might try 10 metres for a local net, which might also get further round the country for distant members. If someone would like to run a net, please discuss via the reflector or contact a member of the committee.

LATEST SOLAR NEWS (Courtesy of Spaceweather News):

SOLAR WIND GRAZES EARTH: A weak stream of solar wind is grazing Earth’s magnetic field today. The gaseous material is flowing from a northern hole in the sun’s atmosphere, pointing not-quite-directly at our planet. NOAA forecasters estimate a 35% chance of polar geomagnetic activity in response to this grazing event.

For further info please visit: http://spaceweather.com

Propagation news from RSGB:

The Sun remained spotless this week, other than the hint of a new sunspot coming around its limb as this report was being written.

The solar flux index reflected this, sitting around the high 60s, although it did reach 71 on Thursday morning. Geomagnetic conditions were quiet at the beginning of the week, but a solar wind stream from a large solar coronal hole was predicted to hit Earth later on Thursday, the 19th. This normally means noisy HF bands, and depressed maximum usable frequencies (MUFs) after a possible initial positive phase.

We are now seeing a shift towards more summer-like ionospheric conditions in the northern hemisphere. At this time there is a chemical change towards more diatomic molecules in the F2 layer and fewer monatomic species. The diatomic molecules are more difficult to ionise and as a result MUFs can suffer.

Coupled with the lack of sunspots, we are now seeing daytime MUFs struggling to get above 16-17 Megahertz at times, despite the quiet geomagnetic conditions.

The upside is that night-time MUFs are staying higher, with seven Megahertz possibly staying open to DX over a 3,000km path through the night. A phenomenon that has been spotted is that the MUF is sometimes rising again for a short period after sunset. It might be worth checking 14MHz around 2000hrs UTC as this has showed itself a few times on the ionosonde data.

Next week, NOAA predicts the solar flux index will remain around 69 and geomagnetic conditions are predicted to be quieter from Monday onwards after the weekend’s high K-indices.

These settled conditions could bring better DX from Tuesday or Wednesday, once the ionosphere has settled. As we’ll explain in the VHF section, you may still have to wait a week or two before the start of the summer sporadic E season.

VHF/UHF:

Last week ended with high pressure near southern areas declining during the weekend as low pressure moved in from the Atlantic towards northern areas.

There may be slightly enhanced tropo conditions around at first but these could weaken as the low takes over. This could introduce showery weather with a prospect for rain scatter on the Gigahertz bands.

The 2018 sporadic E season is nearly here! It usually starts with a few fleeting SSB and CW signals across southern Europe, possibly not within range of UK stations, but with new digital modes, we might be lucky this early.

Since the location of sporadic E geographically can be influenced by the position of the jet stream, there may be some possibility of paths from the UK to the south-east into the Balkans and east to the Baltic states. The other possibility, based on expected jet stream positions, might be from Spain down to the Canaries.

Anyway, before it all kicks off, it is worth making that list of useful beacons on 10m or 6m so that you can quickly find the openings—just Google “G3USF beacons”. Also, use propquest.co.uk to find the daily jet stream positions.

Now we are in April, meteor activity is picking up again. The first significant shower, the Lyrids, peaks Sunday, 22 April sometime between 1000 and 2100 UTC.

Moon declination is still positive, but decreases all week, going negative—that is, south—this coming Friday. Losses will also increase as the Moon heads out to apogee, its furthest point from Earth. It’s another good week for EME then, with long windows and high Moon elevations.

PROPAGATION

HF:

LATEST SOLAR NEWS (Courtesy of Spaceweather News):

INTERPLANETARY SHOCK WAVE: An interplanetary shock wave hit Earth’s magnetic field on April 19th around 23:50 UT. When the shock arrived, the density of the solar wind flowing around our planet abruptly quadrupled. Moreover, magnetic fields in the solar wind near Earth have since intensified 10-fold. These developments set the stage for possible geomagnetic storms in the hours ahead.

What is an interplanetary shock wave? It is a supersonic disturbance in the gaseous material of the solar wind. These waves are frequently delivered by coronal mass ejections (CMEs). Indeed, this one might have been a minor CME that left the sun unrecognized earlier this week. Or it might be an unusually sharp co-rotating interaction region (CIR). CIRs are transition zones between slow- and fast-moving streams of solar wind. They contain plasma density gradients that often do a good job of sparking auroras.

For further info please visit: http://spaceweather.com

Propagation news from RSGB:

The predicted unsettled geomagnetic conditions arrived on Tuesday and continued with the K-index hitting five on Wednesday. This was due an elongated coronal hole on the Sun, with the escaping plasma causing the solar wind to pick up in both speed and density. The wind peaked at more than 550 kilometres per second and widespread visual aurora were reported at high latitudes.

There was a brief ionospheric enhancement on Tuesday evening that saw the critical frequency rise to more than 5 MHz, with the predicted MUF reaching 18 MHz around 1900 UTC. But maximum usable frequencies struggled to get to 14 MHz on Wednesday during the subsequent ionospheric storm. This shows that we can get a brief ionospheric enhancement as the solar material first hits, so it is worth watching the bands.

Otherwise, the Sun remained spotless with the solar flux index sitting in the high sixties.

Next week the solar flux index will remain around 67 and HF propagation will largely be dominated by solar wind effects again. NOAA predicts reasonably settled conditions for the first half of the week, but unsettled conditions again from around the 19th.

At 0631 UTC on April 20 the Australian Space Forecast Centre issued
a Geomagnetic Disturbance Warning.

“Earth is currently under the influence of a high speed stream from
a negative polarity equatorial coronal hole. Geomagnetic activity at
Quiet to Active levels is expected and at times may reach up to
Minor Storm levels if there are notable southward Bz periods.

“INCREASED GEOMAGNETIC ACTIVITY EXPECTED DUE TO CORONAL HOLE HIGH
SPEED WIND STREAM FROM 20-21 APRIL 2018

“GEOMAGNETIC ACTIVITY FORECAST
20 Apr: Quiet to Active
21 Apr: Quiet to Active”

This link to Space Weather Live explains the reference to “southward
Bz periods” above:

https://bit.ly/1S6H68D

Average daily sunspot number over the recent reporting week (April
12-18) rose from 0 to 5.4. Of course, any non-zero sunspot number
lower than 11 is imaginary, because of the arcane method used for
calculating sunspot numbers.

Every sunspot group counts for 10 points, and each sunspot within
that group counts as one point. So one sunspot in one group yields a
sunspot number of 11. Three sunspots in two groups yields a daily
sunspot number of 23. The last time we saw a sunspot number greater
than 22 was February 9-12 when the numbers were 23, 35, 24 and 26.

So an average daily sunspot number lower than 11 must include at
least one zero-sunspot day. In the past reporting week, only three
days had any sunspots.

Average daily solar flux rose from 67.7 to 69.9. Average daily
planetary A index declined from 9.4 to 6.1, while average
mid-latitude A index went from 8.1 to 5.6.

Predicted solar flux for the next 45 days is 72 on April 20-26, 71
on April 27, 69 on April 28 through May 5, 70 on May 6-12, 72 on May
13-19, 69 on May 20 through June 1, and 70 on June 2-3.

Predicted planetary A index is 15, 12 and 8 on April 20-22, 5 on
April 23-25, 8 on April 26, 5 on April 27 through May 5, 10 on May
6, 15 on May 7-8, 10 on May 9-10, 5 on May 11-15, 12 and 10 on May
16-17, 5 on May 18 through June 1, then 10 and 12 on June 2-3.

F.K. Janda, OK1HH of the Czech Propagation Interest Group brings us
his weekly geomagnetic activity forecast for the period April 20 to
May 15, 2018.

“Geomagnetic field will be:
Quiet on April 24-25, 27-28, May 13-14
Mostly quiet on April 22-23, May 15
Quiet to unsettled on April 26, 29-30, May 1, 3-5, 9, 12
Quiet to active on April (21,) May 2, 7-8, 10-11
Active to disturbed on April (20,) May 6

“Solar wind will intensify on April (24)-25, May (2-3,) 5-6, (7-11)

VHF/UHF:

The cold misty weather across the northern North Sea into the Baltic may have set up a few tropo paths, but so far it has seemed fairly quiet. This initial phase of the Scandinavian high will decline over the weekend, but early next week the high will rebuild over the North Sea. It will be better placed and could be more useful during the rest of the week for tropo along the east coast, say from East Anglia to north-east Scotland and eastwards across the North Sea to the Low Countries.

There will also be some occasional thundery developments, mainly in the lead up to this weekend with a hint of potential rain scatter on the Gigahertz bands.

It is mid-April and the 2018 sporadic E season beckons, so it is worth repeating a few basic rules to help those who have never worked it before. Start by checking the European beacons on 10m and 6m during the morning and late afternoon. A classic opening will usually have two phases, one say from 1000 to 1200 UTC and a second in the late afternoon and early evening from 1600 to 1900 UTC. Of course it can happen at other times, so put 10m and 6m in your shack routine during these summer months. Keep QSOs brief, so report and locator will do in these transient events.

April also brings increased meteor activity. The first significant shower, the Lyrids, peaks on 22 April, sometime between 1000 and 2100 UTC.

Moon declination is positive and increasing this week and the Moon is at perigee again on Friday at 368,717km from the earth. It is a good week for EME then, with long windows and high Moon elevations, meaning low ground noise with low path losses.

WADARC meets at – Lions Hall, 21 Roberts Road, Lancing. BN15 8AR.

THE PAST WEEK

Wednesday’s meeting was particularly good as we had a talk on radio surveillance during the 1950s/60s cold war by Brian Spiby. Centred round much of Brian’s early life story, he covered his voluntary recruitment into the Royal Navy and such diverse things as darning socks and listening to the Russian Fire Brigade in a state of panic. Many who were present remarked on how much they enjoyed it.

LATEST SOLAR NEWS (Courtesy of Spaceweather News):

EXITING THE SOLAR WIND: Earth is exiting a stream of high-speed solar wind that sparked a G1-class geomagnetic storm and some very strange aurorasearlier this week (April 9-11). NOAA says there is a 50% chance of polar geomagnetic storms today, subsiding to only 35% tomorrow.

LAST AURORAS OF ARCTIC SPRING? Around the Arctic Circle, the midnight sun is coming, and sky watchers are bracing for a long summer without auroras. A G1-class geomagnetic storm on April 10-11 produced a bright display of lights over Scandinavia–and if it was the last display of the season, it was a good one.

For further info please visit: http://spaceweather.com

Propagation news from RSGB:

Last week saw a continued lack of sunspots as we journey towards solar minimum sometime in 2019–2020. The solar flux index hovered around 68-69, which is only about two to three points above what we can expect when it hits its lowest point. Unfortunately, we are likely to be repeating this sentence quite a lot over the next 12 months or so!

There were no solar flares reported and geomagnetic conditions were relatively calm, with a maximum planetary K index of two. This was due to a lack of earth-facing coronal hole activity, but that isn’t going to last. Next week, the solar flux index is likely to remain around 68, but we can expect unsettled geomagnetic conditions, with the potential for depressed maximum usable frequencies and noisy bands, from the 11th to 15th, as a large coronal hole on the solar equator become geo-effective.

Despite the low solar flux, the current settled conditions means there may be good DX to be had up to 18MHz, and possibly even 21MHz, over this weekend.

It is still a little too early for reliable Sporadic-E openings on 24 and 28MHz and we may need to wait until the end of April or early May, but do check.

Looking more generally, we are starting to see a shift towards more summer-like ionospheric conditions in the northern hemisphere. Daytime maximum usable frequencies may be lower than they were in winter, and east-west HF paths are likely to be worse. But the good news is the HF bands may stay open longer in the evening.

We are already seeing 20 metres remaining open until around 2100 UTC on 3,000km paths, and 40m and 80m continue to be worthwhile evening bands as well.

It looks like another week of uncertain fortunes, although unlike last week, there is at least the hint of high pressure to the northeast of Britain, favouring some potential Tropo conditions from the north of the country to southern Scandinavia and the Baltic. The south of Britain may just be far enough away from the high to see some heavy April shower activity and possible rain scatter on the microwave bands, especially in the southwest.

Now another mention for Sporadic E, which at times of thin HF propagation can liven up 10m, and of course the more traditional 6m bands. The weather patterns can influence this by the distribution of jet streams, and daily charts are available on www.propquest.co.uk along with occasional commentary.

The long winter meteor minimum is drawing to a close soon, with the April Lyrids coming up on the 22nd, so get prepared for better reflections. We’ve just passed minimum Moon declination for the month. Apogee, the point where the moon is furthest away from Earth, is today, so losses are at their maximum and Moon windows are short. We are a week away from declination going positive again, but conditions will slowly improve throughout the week.

VHF/UHF:

In the run up to Easter, it’s been very unsettled again, so there is little chance of enhanced tropo. There will be periods of wet and windy weather and some risk of snow in the north. This Easter weekend there is a hint of a weak high developing over Scotland, which will transfer east over the North Sea. The end result is that the UK is still under low pressure with rain or April showers and early signs that there may be more significant low developing towards the following weekend with a chance of severe gales. It’s a long way off, but it is a flag to check the forecasts carefully as we get closer. In the odd quieter days beforehand, it may be worth checking those mast guys before the end of the second week.

So what modes are options? You can try rain scatter on the microwave bands from April showers, sporadic E on 10m and 6m, especially on weak signal digital modes at the end of next week as strong jet streams arrive, but sadly no strong signal for tropo.

Moon declination is negative again and at minimum next Saturday. Apogee is only seven days away so losses are high and increasing and moon windows are shortening.

FINALÉ

In one of the RSGB forums there has been discussion regarding VHF & UHF repeater use, especially in the digital domain.

Paul GW8IZR writes:

Sadly you need to be prepared to listen to hours on end of complete silence, punctuated by a few VERY short contacts ‘for fear of tying up the network’

Reply from John, G4SWX

This is one of the slightly disturbing results of the ‘digitalisation’ of UK repeaters:

1) They have divided the activity between FM+ Fusion, Dstar and DMR. All of which are pretty incompatible. Therefore amateurs with one system find low activity and don’t come on very much!
2) There are some that resent the networked clusters of repeaters being tied up and discourage others from doing so. Therefore activity drops.
3) The very cheap price of Chinese VHF/UHF hand held FM transceivers makes it very easy for new Novice amateurs to become active. Yet the FM activity is not there to keep their interest going. This should be of concern to everybody as new blood has almost dried up!

The end result has been a very drastic fall in 432MHz activity in the past 5 years or so despite the very large increase in the number of repeaters! This drop is far greater than has been seen on other bands and modes of activity! Some repeaters do not see much activity in a whole week! I am concerned as Ofcom do monitor 70cms and of all of our VHF/UHF bands it is the one that faces the greatest threat. Although ‘local chat’ is not my ‘cup of tea’ we do need activity to maintain our position with the regulator.

Amateur radio is about communication, it seems to me that the many ‘tongues’ of UHF voice have led to a situation of ever decreasing numbers of contacts because the different technologies are incompatible. If ever there was a ‘Tower of Babel’………….

From Paul, GW8IZR:

Yes John it is a concern. I have a DMR set in the car and monitor the network on many journeys and I have to say the number of contacts is minimal.

It is regrettable that the many factions cannot see i2i as it would be possible to link all of the technologies at the Internet level

At the moment all we have is many kilowatt hours of electricity being burned to no advance of technology or communication.
Internet linking and repeaters in general are not my thing, but in modern cars if you want to have some kind of radio with the simple antenna afforded by UHF it’s kind of the best option for a bit of company on long journeys (especially when Jeremy Vine is on)

In my terminal scan group I have the local UHF FM repeater and I’ve noticed that there are far more contacts on that than any of the numerous talk groups supported by the DMR repeater (they are co-sited) so it’s clear that the “band police“ active discouragement of the network occupation it’s having a detrimental effect.

————————————————————-

Some food for thought when it’s so obvious that our own repeater GB3WO is grossly under-used and VHF/UHF activity in general seems to have hit an all time low. We owe it to ourselves to maintain activity, even if it’s to tell Ofcom that we do need the bands!

PROPAGATION

Propagation News – 1 April 2018
rsgb | March 29, 2018

As we move into April 2018 it is time to think about updating the latest smoothed sunspot number if you are using a VOACAP-based propagation prediction program.

There are a number of different methods used to smooth or average sunspot numbers, but VOACAP recommends the adjusted SSN from the Solar Influences Data Centre in Belgium. So we’ll settle for an SSN of eight. This tells us that solar activity is very low and the predicted solar flux index of 68-70 for this week basically says we are likely to continue to have no sunspots at all. But that doesn’t mean we will have no HF propagation. We can expect to see daytime openings up to 18MHz, with occasional openings on 21MHz as well. It is a little too early for the main sporadic E season, so openings on 12 metres and 10 metres will be few and far between, but not impossible. This time of year does favour north-south paths for F2 layer openings on the higher bands so do check 12 and 10 metres.

The good news is that the NOAA longer-term forecast for next week is for quieter geomagnetic conditions. This often involves crystal ball gazing as the Solar Dynamics Observatory cannot see around the edge of the Sun, but quieter geomagnetic conditions, shown by lower K-indices, could spell better conditions on the HF bands.
Eighty metres remains a mainly night time band and 40 metres may provide 24 hour contacts, with longer paths opening up after dark. It might also be a good time to try a new mode such as FT8, which is getting rave reviews for its ability to secure DX contacts with low power and compromise antennas.

VHF and up

This week is a rather long range tropo forecast due to the Easter break and this week’s GB2RS deadline having been brought forward.

In the run up to Easter, it’s been very unsettled again, so there is little chance of enhanced tropo. There will be periods of wet and windy weather and some risk of snow in the north. This Easter weekend there is a hint of a weak high developing over Scotland, which will transfer east over the North Sea. The end result is that the UK is still under low pressure with rain or April showers and early signs that there may be more significant low developing towards the following weekend with a chance of severe gales. It’s a long way off, but it is a flag to check the forecasts carefully as we get closer. In the odd quieter days beforehand, it may be worth checking those mast guys before the end of the second week.

So what modes are options? You can try rain scatter on the microwave bands from April showers, sporadic E on 10m and 6m, especially on weak signal digital modes at the end of next week as strong jet streams arrive, but sadly no strong signal for tropo.

THE PAST WEEK

The “Search and Rescue” trip arranged by Alex, 2E0UMD was a great success, according to reports from those who attended. Members spent several hours at the facility and despite the crew being on a “shout”, there was a very informative tour of the facility.

Last Wednesday’s meeting was a talk on plastics by Norman, M0EBI who obviously knows his subject very well. Norman covered a brief history of how plastics came to be developed, followed by a trip into molecular science, showing how different plastics with varying capabilities can be made, sometimes by changing one small but significant component.

LATEST SOLAR NEWS (Courtesy of Spaceweather News):

RARE SOLAR MINIMUM SUNSPOT: Almost every day this month, the face of the sun has been utterly blank. Today, however, a new sunspot is growing near the sun’s southeastern limb, pocking the surface of our star with several Moon-sized dark cores.

Only on the eve of Solar Minimum would such a puny sunspot attract attention–and that is exactly where we are. Sunspot numbers are plummeting toward a deep nadir of the solar cycle expected to hit bottom in 2019-2020. For the foreseeable future, every sunspot is a rarity worthy of note.

This sunspot will probably remain small and quiet. But we could be wrong. Occasionally, potent sunspots emerge during Solar Minimum, unleashing powerful flares. Astronomers with backyard solar telescopes are encouraged to monitor this one … just in case.

ARLP011 Propagation de K7RA

At 2332 UTC on March 22 the Australian Space Forecast Centre issued a geomagnetic disturbance warning for this weekend, March 24 and 25.

“Expect the geomagnetic activity to increase to mostly Active levels with isolated periods of Minor to Major Storm levels due to a high speed solar wind stream associated with a negative polarity coronal hole becoming geo-effective”.

In last week’s report, ARLP011, there were no sunspots over the reporting week. On March 15 one new sunspot appeared for a sunspot number of 11, which is the minimum non-zero sunspot number. The next day it was gone, then a new sunspot appeared March 17. Sunspot numbers on March 17 and 18 were 15 and 13, then none for the rest of our reporting week, March 19 to 21. So the average daily sunspot number increased from 0 over the previous week to 5.6 over the most recent 7 days, ending Wednesday March 21.

Average daily solar flux over the same two periods increased from 67.7 to 69.3. Geomagnetic indices about doubled, with average planetary A index changing from 7.1 to 14.4, and mid-latitude A index increasing from 5.7 to 11.3.

Predicted solar flux is 68 on March 23 through April 2, 69 on April 3 and 4, 70 on April 5 to 15, 69 on April 16 and 17, 68 on April 18 to 29, 69 on April 30 through May 1, and 70 on May 2 to 6.

Predicted planetary A index is 8, 22, 24, 18 and 8 on March 23 to 27, 5, 15, 10 and 8 on March 28 to 31, then 5 on April 1 to 9, then 8, 15 and 20 on April 10 to 12, then 15 on April 13 and 14, then 8 and 12 on April 15 and 16, 18 on April 17 to 19, 15 and 8 on April 20 and 21, and 5 on April 22 to 25, 8 on April 26 and 27, and 5 on April 28 through May 6.

The spring equinox began at 1615 UTC on Tuesday, March 20 in the Northern Hemisphere. At that moment solar radiation was equally distributed between the Northern and Southern Hemisphere. Except for the low solar activity, the beginning of spring should be an ideal time for worldwide HF communication.

VHF/UHF:

Monitoring ON0VHF has produced varying results from ‘unheard’ to 5/2/9 and back into the noise. This pattern can sometimes repeat may times in an hour. This could be due to ‘aircraft flutter’ or to changes in the Troposphere. There have been no enhancements this week due to temperature inversions.

FINALÉ

During Norman’s lecture on plastics, he mentioned that the new Dreamliner aircraft is made from just two plastic mouldings, which makes it light and fuel efficient. I wonder how this affects its resistance to turbulence. Is it more likely to be bounced around the sky? Has anyone travelled on one yet?

LATEST SOLAR NEWS (Courtesy of Spaceweather News):

AURORAS EXPLODE OVER FINLAND: Earth is entering a stream of solar wind flowing from a sprawling hole in the sun’s atmosphere. First contact with the gaseous material on March 22nd sparked a bright display of auroras over Scandinavia. “The sky literally exploded right above our heads,” says Didier Van Hellemont, who sends this picture from Luosto, Finland:

“We enjoyed fine auroras for several hours as we walked through the woods from a snow-covered mountain in northern Finland,” says Van Hellemont. “And I hope there will be more in the nights ahead.”

Indeed there will be. Earth is only in the outskirts of the stream now. Our planet is about to move deeper into the stream where we will experience faster-moving rivulets of solar wind, with speeds exceeding 600 km/s (1.3 million mph). NOAA forecasters estimate a 55% chance of G1-class geomagnetic storms on March 24th and 25th.
