Using the W5OLF 500mW 10m WSPR beacon today

W5OLF WSPR beacon – complete – no PC needed

This WSPR-AXE really is a very impressive little rig, in my case for 10m WSPR.  Because of my current disabled state –  I find all electronics building just about impossible – Jay very kindly sold me a built unit to evaluate. Results in just a few hours of operating have been truly impressive. No PC is needed as long as the push button is pressed at the start of an even minute. Jay says it stays stable for weeks thereafter. I ran mine for 3.5 hours and got masses of decodes. After lunch it has been getting LOTS of spots from the USA. I am sure it will reach Australia soon.

The unit needs about 15 minutes to frequency stabilise and after that it always on, but it randomises the slots within the WSPR transmit window. This means it is unlikely to be “clobbered” by more powerful stations or cause others co-channel issues.

Best DX report (so far) today is FR1GZ (9724km).
