Dear Mal, Mike, LF Group,

The TM5AST expedition was able to maintain a consistently high signal level
for several hours after dark using their kite antenna, rather demonstrating
how effective it can be, and plenty of time for even a QRSS30 QSO. 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.

Cheers, Jim Moritz

From my experience of kite operation on LF as GW3XDV/P, it is quite
possible to fly a kite that is very stable for long periods. 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
