[ARC5] BC453 FET BFO decoding now.

[J Mcvey]

Just got back home today and installed the FET BFO circuit  for actaully reception testing.The good news is that I can now decode WSPR-2 with the BC453.
However , it only partially cured the drift problem. Before, there were two drifting oscillators, now there is only one, so after a long warm up period.( about an hour and a half) the LO stabilizes enough to decode WSPR-2.The farthest one tonight is K5DNL @2099 miles.

I am in the process of the write-up which I should be publishing in a couple of days at the latest.This particular BC-453 was only recapped in a few areas none of which were in the rf section. Maybe changing  those caps will help?
BTW the BC453 is running on a dynamotor @25VDC unregulated.The B+ is about 220V.
