As for the time of year, Joe, VO1NA and myself had our first QSO during June a couple of years ago, using QRSS30. Admittedly, it took several attempts, and a bit of luck was required to get the whole QSO into the available darkness hours, but eventually it worked, and most of the time some signals were seen even when a complete QSO was not possible.

I am sure that G3YXM (whose GM3YXM/P work gave several people their first GM) will agree. As for timing, this time of year it gets light at about 0430, which would allow time for a callsign ort two at QRSS30 before transatlantic propagation faded. A bigger problem would be getting enough wind at that time of day. Mike, G3XDV ===========
