Web SDR

The club has a WebSDR receiver and it can be found on this link. http://websdr.wadarc.org.uk:8073
If you prefer to avoid using a DNS server the direct link is http://81.143.239.74:8073

There is a very comprehensive help file that can be accessed from the menu bar at the top of the screen.

A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals.

There are several flavours, ours is OpenWebRX which is free software that can work with a number of simple soundcard radios and runs on a Linux machine. Here is a link to a world map of OpenWebRX receivers https://www.receiverbook.de/map?type=openwebrx&band=

Another popular variation is KiwiSDR. This is a complete unit which which comes preloaded with OpenWebRX and covers 10 kHz – 30 MHz. A link to a world map of KiwiSDR receivers is here http://rx.linkfanel.net/

An oldie but goodie is WebSDR, the software is no longer distributed but there are many existing servers running. The link is http://websdr.org/ , the map is at the bottom of the WebSDR page.

The club receiver is connected to a discone aerial at 20 feet. The aerial works remarkably well on the 40 metre band where the signals are strong. It also can hear interesting VHF and UHF signals but the sensitivity is poor. It does however seem to perform very well on the digital modes.

The receiver can accommodate several users but can only work on one band at a time. The number of clients connected is shown at the bottom of the screen. If only one is shown you can change the band without affecting anyone else.

When the receiver is on a particular band it sends FT4, FT8 and WSPR data to the PSKReporter website that is on this link https://pskreporter.info/pskmap.html. Look under the callsign G1WOR.

When the radio is not being accessed it reverts to a band programmed by the Sysop.

Users have found the site is easier to use on a PC as the cursor is moved with a mouse or touchpad. If you are using a tablet or a smartphone a mouse can be used if it is plugged into the USB port. An adaptor may be required.

Above all, please enjoy.
