Three stations G8EUX, G6AVK and G3ZJO ran WSPR for more than 12Hours on 6m, 50.293MHz dial on 2 May 2009.
Apart from Spots from G8EUX of G3ZJO at 15Km there were no other de-codes. G3ZJO was RX only, the spots of G8EUX by G3ZJO have been done many times before.
G3ZJO had the advantage of continuous beaconing, multi modes, 5ele Rotatable Beam and the grabber at G6AVK activated.
Previous tests using 100mW of Slowfeld produced very useful copy at G6AVK of G3ZJO both from the direct beam heading and indirectly by beaming across the North South Air Corridor. The same beam headings were used for the 2 May tests.
G3ZJO also ran a 3 band co-linear antenna for a short time this produced the occasional burst of Aircraft Scatter at G6AVK. Peter, G8EUX produced a little WSPR and me, G3ZJO produced a short bit of QRSS.
G3ZJO could produce constant signals on the Grabber at G6AVK with 100mW to the 5ele Beam,(ERP nearer to 1Watt, I will quote RF out at the TX across 50 Ohms)constant but rarely usable due to multipath.
The most copyable signal that I observed in the test period was the Hell Ident in the following capture. 5 Unit Hell G 3 Z J swoops downward with Doppler shift from an Aircraft reflection and the O is back 'on the line'.
Several versions of QRSS Morse and WSPR proved useless under these conditions, 5 Unit Hellschriber produced some results. Previous activity on 6m by many stations has proved to be disappointing due to multipath signals. The results using Slowfeld which was produced to exploit Aircraft Scatter provided superb communications.
