Hi Eric.
Fine.
So i will stay silent and stay for RX tonite as soon as the sun goes 
down on your side. The highest probability between us seems to be 
arround *1:30...3:00 UTC* these days. The path can be open just for 20 
minutes. So it may be better to use a high duty cycle, like 50% during 
that time. Stations from the UK or PA are in a preferred location of 
course. Maybe many of them will take part in the night :-)
600W sounds suitable :-)
73, GL,

Stefan

I'll try increasing power tonight.  Can go up to 1kW, but while running
WSPR2 prefer to top out at 550-600W (amp = modified SB-1000 linear).
