    10m FT8 (Sunday)

    Posted: 09 Jan 2022 03:27 AM PST http://g3xbm-qrp.blogspot.com/2022/01/10m-ft8-sunday_9.html

    On 10m FT8 today. Even my 2.5W brief transmission was spotted in
    Scandinavia 5 times. Mostly RX only with 42 spots at 1127z.

    Solar flux is 102 and the SSN 31. A=14 and K=3.

    472kHz WSPR RX (Saturday)

    Posted: 08 Jan 2022 12:24 PM PST http://g3xbm-qrp.blogspot.com/2022/01/472khz-wspr-rx-saturday.html

    As my transverter is broken on TX, I am on 472kHz WSPR RX with the coax to
    the 144MHz big-wheel tuned via the ferrite rod ATU for a change.
    The RX was turned on at about 1900z. So far, no spots.
    UPDATE 2024z: 7 spots so far with the furthermost LA8AV/1 (1035km).

    8m NoV application

    This was first submitted mid October to OFCOM, so I chased today and got an immediate acknowledgement saying, along with other stuff:Dear Customer,
    We have received your request and a member of the Licensing team will be processing your enquiry in due course. Your Case Reference number is
    provided above, and we would ask you to ensure this is quoted on all future communications.
    Planned system maintenance Thursday 25th November to Monday 13th December
    Ofcom are in the process of upgrading their Finance systems and as such licensing services will be significantly reduced between Thursday 25th
    November to Monday 13th December.
    They cannot even update their own acknowledgements!! I presume this is
    2021. Let us hope they wake up next week and manage to give a meaningful response. Miracles do happen.
    In the meantime boys and girls carry on playtime...

    Early 481THz experiments

    Posted: 08 Jan 2022 07:04 AM PST http://g3xbm-qrp.blogspot.com/2022/01/early-481thz-experiments.html

    This photo popped up as a Facebook memory today.
    It shows my early trials trying to receive my 481THz optical CW beacon in daylight along the road. As I recall, signals were very strong. Much much further was achieved later including over the horizon (NLOS).
    I guess this was 2012? The gear still exists and still works. It has not
    been used much since before my stroke.

    Original 10m Chirpy?

    Posted: 08 Jan 2022 01:55 AM PST http://g3xbm-qrp.blogspot.com/2022/01/original-10m-chirpy.html

    This photo was (re)discovered yesterday. I think it was the original Chirpy transceiver that was replaced by the Lesser Chirpy as this had far less
    I think this dates from 2011 or 2012.

    10m FT8 QRP (Saturday)

    Posted: 08 Jan 2022 07:21 AM PST http://g3xbm-qrp.blogspot.com/2022/01/10m-ft8-qrp-saturday.html

    The 10m FT8 gear was turned on at 0920z. So far nobody has spotted my 2.5W
    QRP and just one station has been spotted on RX - DO1DU (533km) at 0940z. UPDATE 1520z: With just 17 stations spotted, I was beginning to suspect something was wrong at my end. A quick check indicated all here was well.
    On RX the furthermost is ZS4JAN (9393km). I did a brief TX with 2.5W at
    about 1510z, but nobody spotted me.

    472kHz ATU

    Posted: 07 Jan 2022 11:12 PM PST http://g3xbm-qrp.blogspot.com/2022/01/472khz-atu.html

    When running a long wire (actually a short wire, HI) on 472kHz TX with my
    12W output transverter, I used a simple ferrite rod ATU on the shack table.

    As long as ferrites don't saturate, they are perfectly fine in this application. With 10mW ERP, I have been spotted in Finland with this arrangement many times on 472kHz WSPR.
