The recent geomag and lovely Auroras here in Alaska has LF and MF condition=
s 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  beaco=
ns on 40m pre dawn.

 Im like George looking at BBC Radio 4 at the moment over the Pole and I ca=
n just see its (or a)  carrier at dot 120 slow. Its never really very stron=
g 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 R=
F 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 curr=
ent is around 50A or so - testing continues.
