    10m QRP WSPR TX (Wednesday)

    Posted: 17 Nov 2021 01:34 AM PST http://g3xbm-qrp.blogspot.com/2021/11/10m-qrp-wspr-tx-wednesday.html


    As the 10m antenna was free, I put my W5OLF stand-alone WSPR beacon on
    using 500mW. So far, just a local spot from G4KPX (14km).

    15m FT8 RX (Wednesday)

    Posted: 17 Nov 2021 04:05 AM PST http://g3xbm-qrp.blogspot.com/2021/11/15m-ft8-rx-wednesday.html


    Like yesterday, I am again on 15m FT8 RX using the coax up to my 2m
    big-wheel as the antenna, ad hoc though it is! After about 15 minutes, 23 stations already spotted.
    UPDATE 1204z: 176 stations spotted today on 15m FT8 RX today.

    8m experimental licences in the USA

    Posted: 17 Nov 2021 01:00 AM PST http://g3xbm-qrp.blogspot.com/2021/11/8m-experimental-licences-in-usa.html


    My understanding is that 7 experimental licences have been approved for the
    8m band in the USA. One station has already been copied in the UK. With F2 propagation improving and summer Es, it is highly probable that others in
    the USA will be copied in Europe.
    My own view is that the chances would be greatly enhanced if all
    experimental stations and beacons at 8m had an FT8 sequence that allowed
    all to be monitored with one dial setting. This implies that all are within
    a few kHz of each other.
    In the future, 8m could be a really interesting amateur band. If OFCOM can
    find 2000000Hz of "precious" VHF spectrum for DATV experiments, I hope they
    can surely find the odd 50Hz of 8m spectrum for propagation research, especially at lower power.
    The more temporary permits that are applied for, and obtained, around the
    world the more useful research can be done.
    Small steps....

    15m antenna?

    Posted: 16 Nov 2021 07:30 AM PST http://g3xbm-qrp.blogspot.com/2021/11/15m-antenna.html


    Judging by the results on FT8 RX today with my very improvised 15m antenna,
    I am tempted to convert my Par end fed antenna to 15m.
    I suppose I could make it cover 10m and 15m by putting up 2 wires. Already today, I have spotted 350 stations on 15m FT8 RX. Don't forget that some of
    the time the PC had closed down with a flat battery too! With a "proper" antenna , I would expect even better results.
    All that should be needed to cover 15m is a longer wire.

    10m QRP WSPR TX (Tuesday)

    Posted: 16 Nov 2021 11:28 AM PST http://g3xbm-qrp.blogspot.com/2021/11/10m-qrp-wspr-tx-tuesday.html


    At the moment I am on 10m WSPR TX using 500mW from my stand-alone W5OLF 10m WSPR beacon. So far, (at 0930z) 3 spots only from local G4KPX (14km).
    UPDATE 0955z: 15 spots so far of me with the furthermost EA8BFK (2880km). UPDATE 1024z: 36 spots of me so far today. EA8BFK has been getting me as strong as -3dB S/N.
    UPDATE 1926z: QRT. 3 unique spots today.

    15m FT8 RX (Tuesday)

    Posted: 16 Nov 2021 11:31 AM PST http://g3xbm-qrp.blogspot.com/2021/11/15m-ft8-rx-tuesday.html


    As a complete change I am on 15m FT8 RX using the coax up to my 2m
    big-wheel antenna. The SWR looks quite low without any additional ATU. So
    far, 28 stations spotted.

    UPDATE 1131z: 158 stations spotted on 15m FT8 RX with this daft antenna!
    UPDATE 1213z: 207 stations spotted so far.
    UPDATE 1435z: Doh!! Guess who forgot to turn on the PC charger? The laptop went flat, so I had to turn it on again and check time was synced. 315
    stations spotted with lots of USA stations.
    UPDATE 1557z: So far today, 373 stations spotted on 15m FT8 RX with the improvised antenna.
    UPDATE 1835z: 403 stations spotted on 15m FT8 RX.
    UPDATE 1929z: QRT.

    Oscar 100 activity

    Posted: 16 Nov 2021 01:22 AM PST http://g3xbm-qrp.blogspot.com/2021/11/oscar-100-activity_16.html



    Every few weeks I try to give an update on activity levels on the
    narrowband transponder on geosynchronous Oscar 100. I last looked yesterday
    at activity and I can report that there is still plenty of space and
    activity looked low. The web SDR at Goonhilly is a useful resource.
