Subject: LF: conditions and what not to
do
The recent geomag and lovely Auroras here in Alaska has LF and MF
conditions still wanting. HF has been very poor too with very little but Im
slowly (very slowly) seeing a recovery and hearing the Russian single
letter beacons on 40m pre dawn.
Im like George looking at
BBC Radio 4 at the moment over the Pole and I can just see its (or a)
carrier at dot 120 slow. Its never really very strong here compared with some
of its European more QRO partners.
Ive been repairing the tuning unit
and continue slapping myself on the back of the hand for causing a 7.5nF G3
Capacitor to fail by running too many RF amps thru it. The unit failed by
reducing its capacity to 3nF. Heres the sad picture of the failed cap before
it turned into a door stop.

Ive
added more series parallel lower value (less than 2nF) Mica capacitors to the
design - I need around about 8nF to resonate the Tx loop and RF current is
around 50A or so - testing continues.
