Simple regen RX

There is little to beat the sheer thrill of copying stations on a very
simple homebrew RX.
The one on my website is one example, but there are plenty on the net. I
was surprised just how well something so simple works. Yes, SDRs and
complex rigs may be better, but you too may be surprised how well such
simple circuits can work.

I even made mine into a simple 80m transceiver!

As usual, I did a brief TX slot with 2.5W (spotted by 2 stations including
EA6) , but now RX only. Es evident with 16 stations spotted on RX.
UPDATE 1453z: 35 stations (all in Europe) spotted on 10m FT8 so far today. UPDATE 1914z: Just 37 Europeans spotted so far with no sign of stations in South America.
UPDATE 2052z: Just one South American spotted on 10m FT8 RX and he was
only just spotted.
UPDATE 2114z: Now 6 South Americans spotted. I think they seem to be coming through later now. QRT soon.
