To take advantage of any translantic tests and be in with a chance,
I have ordered some 50 ft fibre glass marine masts to extend the 100 ft
tower to 150 ft and the 65 ft tower to 115 ft and the Tyrone(NI) 120 ft
tower to 170 ft. All antennas have elaborate elevated insulated ground
systems plus is some cases miles of sheep fence .
With the current towers,  that is the height limit and if it works fine
if not I shall have to be content with local qso's around Europe.
I am waiting for someone across the atlantic with a suitable antenna and
power to commence some tests. Will leave a wide band recorder running 24
hrs each day to monitor activity when I am not available, and scan it
later on a spectrum analyiser for activity hits.
