    Es bad day?

    Posted: 17 Jul 2022 01:38 AM PDT http://g3xbm-qrp.blogspot.com/2022/07/es-bad-day.html


    It is still quite early, but I get the impression that Es will be infrequent today on 10m and 8m. Of course, things can rapidly change!

    90MHz or 90 MHz??

    Posted: 17 Jul 2022 01:21 AM PDT http://g3xbm-qrp.blogspot.com/2022/07/90mhz-or-90-mhz.html


    After nearly 40 years as a professional RF engineer you would think that I should know!!
    Should there be a space after the number before the kHz, MHz or GHz or not? Can either be used? I should try to use the correct format.
    One thing is clear. Most engineers don't care!

    at 6km away.

    One of the areas missing from my experiments is computers. When it come to Raspberry Pi devices I know nothing.
    Apparently a Raspberry Pi Pico is soon to be available for $6 that includes 802.11 wireless support.
    It won't be long before some enterprising amateur does a complete 2.4 GHz transceiver on a Pi board!

    10m WSPR QRP (Saturday)

    Posted: 16 Jul 2022 01:53 PM PDT http://g3xbm-qrp.blogspot.com/2022/07/10m-wspr-qrp-saturday.html


    As the PC, rig and antenna are free, I am on 10m WSPR TX with 500mW from
    the W5OLF beacon. So far today, just spotted in northern Spain. It is now 1000z.

    UPDATE 2040z: 9 unique stations have spotted my 10m QRP WSPR beacon today. Activity on FT8 is greater, but I am pleasantly surprised by the WSPR activity. On WSPR, most spots of me are by Es in Europe.

    Yet again I am on QRP 8m FT8 TX on 40.680 MHz USB dial. So far, spotted by EA3ERE (1153km). Nothing on RX.
    UPDATE 1830z : 2 spots of my 8m QRP FT8 TX today (see map). Now QRT.

    10m QRP FT8 TX

    Posted: 15 Jul 2022 08:33 AM PDT http://g3xbm-qrp.blogspot.com/2022/07/10m-qrp-ft8-tx.html


    As 8m wasn't looking very promising here this afternoon, I have QSYed to
    10m FT8. My QRP TX signal has been widely copied in Europe and on RX I am copying the stations shown on the map.

    8m experiment (Monday)

    Posted: 15 Jul 2022 08:42 AM PDT http://g3xbm-qrp.blogspot.com/2022/07/8m-experiment-monday_15.html


    Today I returned to 8m FT8 QRP TX on 40.680 MHz USB dial. This resulted in
    my first report from Denmark.
    UPDATE 1543z: Now QSYed to 10m FT8.
