Condolences on the Sangamo's demise. How about an 'after' picture?=20

Slow LF/MF improvement 'down here' as well. Static approaching =
summertime levels isn't helping the RX situation. =20

  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.
