    2m FT8 QRP (Thursday)

    Posted: 13 May 2021 01:44 PM PDT http://g3xbm-qrp.blogspot.com/2021/05/2m-ft8-qrp-thursday.html


    At the moment, I am on 2m FT8 QRP with 2.5W and the big-wheel omni antenna.
    It is now 1004z and I have spotted 3 stations on RX and I have been spotted
    by 7 stations with the furthermost GI6ATZ (479km) on TX.

    See http://82.71.9.63:8080/cap/ for a local (to Cambridge) 2m FT8 grabber. Stations spotting my
    2m FT8 QRP to1256z todayUPDATE 1228z: 7 stations spotted on RX and 12
    stations have spotted me on TX with the furthermost EI2FG (565km).

    UPDATE 1256z: Now my QRP has been spotted by 13 stations.
    UPDATE 2040z: Practically all the spots this evening were G stations. This suggests most of the propagation was "flat band tropo" rather than scatter.
    Now QRT. I wonder if scatter is linked to no rain. Today was pretty wet.

    The Exeter rally has been postponed until September 12th. Hopefully by then things will be more normal in the UK.

    70cm FT8 yesterday

    Posted: 13 May 2021 01:58 AM PDT http://g3xbm-qrp.blogspot.com/2021/05/70cm-ft8-yesterday.html


    70cm FT8 has the potential to be a game changer.

    For a long time I have suspected that scatter modes might be better on 70cm than on 2m. Last night there was a sort of contest.
    Last evening 29 stations were spotted in 6 countries (see map) with just a
    2m (144MHz) big-wheel omni antenna. 2 of these were 479km away! Imagine
    what would have been possible with even a small beam.
    If there was regular 70cm FT8 activity I think surprising distances would
    be worked at any time.
