Weekly Bulletin – May 18 2018

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


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!

Winter 2017 edition published –



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!


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 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.

Beacons often heard in our area:


GB3WSX – IO80QW – 70.007 MHz

GB3BAA – IO91PS – 70.016 MHz

F1ZXK – JN18KF – 144.438 MHz

F5ZSF – IN88GS – 144.409 MHz

GB3VHF – JO01EH – 144.430 MHz

ON0VHF – JO20HP – 144.418 MHz


F5XBA – JN18KF – 432.830 MHz

GB3UHF – JO01EH – 432.430 MHz

ON0UHF – JO20ET – 432.567 MHz

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:

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!
