    Simple regen RX

    Posted: 31 Aug 2021 08:03 AM PDT http://g3xbm-qrp.blogspot.com/2021/08/simple-regen-rx.html

    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.
    See https://sites.google.com/view/g3xbm4/home/hf-mf-and-lf/homebrew/80m-or-40m-regen-rx .
    I even made mine into a simple 80m transceiver!

    10m FT8 QRP (Tuesday)

    Posted: 31 Aug 2021 02:14 PM PDT http://g3xbm-qrp.blogspot.com/2021/08/10m-ft8-tuesday.html

    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.
