    70cm FT8

    Posted: 27 Jan 2022 01:03 PM PST http://g3xbm-qrp.blogspot.com/2022/01/70cm-ft8_27.html


    A few moments ago I turned on 70cm FT8. After an initial QRP TX session
    (no spots of my 2.5W to the 2m big-wheel omni antenna) I am now RX only.
    UPDATE 2104z: No spots.

    As far as I know the Lincoln Shortwave Club rally is on this Sunday January 30th, but I suggest you check before travelling any distance.
    The Canvey Rally in February has been cancelled I understand.
    As always in these uncertain times, it is always worth checking if rallies
    are cancelled or postponed.

    FT8 RX with non-resonant antennas

    Posted: 27 Jan 2022 02:32 AM PST http://g3xbm-qrp.blogspot.com/2022/01/ft8-rx-with-non-resonant-antennas.html


    In the last day, I have been amazed at the results with non-resonant
    antennas on FT8 RX. May be I shouldn't be.
    On 160m FT8 RX one often has to add attenuation and, as long as the S/N is fine, it will still get results.
    On 15m FT8 RX, I guess my 10m antenna is a few dBs down, but as long as the
    S/N is sufficient I will still get decodes.

    15m FT8 RX

    Posted: 27 Jan 2022 07:03 AM PST http://g3xbm-qrp.blogspot.com/2022/01/15m-ft8-rx.html


    At the moment, I am monitoring 15m FT8 RX with the 10m antenna. I have been
    on for about 10 minutes. At 1010z, 43 stations spotted.
    UPDATE 1502z: 684 stations spotted today on 15m FT8 RX.

    This was a good session on 160m FT8 RX. In all, 546 stations were spotted including many in the USA. Much to my surprise, I had left the 10m antenna plugged in, so this was on a very short, non-resonant antenna!
