    Lesser Chirpy

    Posted: 26 Aug 2021 07:22 AM PDT http://g3xbm-qrp.blogspot.com/2021/08/lesser-chirpy.html

    When I was fitter, I enjoyed designing and building. Sadly this is much
    harder now. Like all of my circuits, I am sure they can be improved. I make
    no claims for originality and take inspiration from many sources. My wish
    is that you use my circuits as the starting point for your own ideas.

    Looking back many years, I designed the Lesser Chirpy for 10m CW.
    Originally I started with the Chirpy, but it chirped too much! The Lesser Chirpy more or less stopped the chirp. This was a "for fun" rig. It does
    work, but I was concerned about calling CQ over weaker stations as the RX sensitivity was not as good as modern rigs. My recommendation is ensure
    that calls are not made over other stations. Fine to call others, but be
    very mindful of other stations.
    The original name was the XBM10-2, but Lesser Chirpy was more meaningful!

    10m FT8 QRP (Thursday)

    Posted: 26 Aug 2021 11:16 AM PDT http://g3xbm-qrp.blogspot.com/2021/08/10m-ft8-qrp-thursday.html

    After a brief TX period with 2.5W with just 1 spot by G4KPX (13km), I am
    again 10m FT8 RX only. At 1127z, just one station spotted - HB9SNR (784km). UPDATE 1803z: Just 2 stations spotted so far today. Es is "sporadic" and today, so far at least, looks poor on 10m FT8 RX. As far as I can remember
    this is the poorest day on 10m for some months.
    UPDATE 1815z: Did I speak too soon? F1RAD (867km) in SW France spotted on
    10m FT8 RX. Also my 2.5W was spotted by local G4BAO (8km).

    As far as I know, the Torbay rally on Sunday August 29th and the Huntingdon club (HARS) rally on Monday August 30th are ON, but the Milton Keynes rally
    on Bank Holiday Monday has been postponed until next year (2022).
    As always check before setting out.
