For several years I have had an appeal on my website for a capable Ham to try Slowfeld with me.
I see from archive material that in 2007 I was appealing on the Packet Radio Network and making test transmissions anyway, just in case.
At around the same time some QRSS Knights were doing it, I was not aware of the Knights.

My previous posts show the hopeless signals on QRSS and WSPR over the 50MHz path between here and G6AVK.
Quite typical of WSPR on 6m the signals are there but the scatter is so great that decodes are rare. My thoughts turned back to Slowfeld.

What you need is that capable Ham at the other end of the path, none better than G6AVK, I put forward the idea ready for his return from a hard day at work (with overtime). While his dinner cooked the software was installed and the tests commenced.

My first transmission produced readable Hellschriber at his end.

Next I took a TX session from him.

Finally I watched my signal on the G6AVK Grabber and turned the beam so that only signals scattered from aircraft were arriving, the TX power was only mWatts.

The results are astounding when QRSS3 FSCW fails and also WSPR then good old Hell comes to the fore.

Many thanks are due to G3PTT for the software which I have tried for several years to put to use. A superb mix of modern computer methods of signal analysis and an ancient visual data mode.
