    472kHz (630m)

    Posted: 19 Feb 2022 04:32 AM PST http://g3xbm-qrp.blogspot.com/2022/02/472khz-630m.html


    This winter I have been on 472kHz less often and only RX.

    With my homebrew transverter (measured ERP 10mW) it was regularly copied in Norway on WSPR. It has been copied in Finland several times.
    In every case the antenna was the earth-electrode in the ground. The transverter was in QST some years ago and produces about 10W into 50 ohms.
    It was designed by me. Several people have made copies.

    Frustration

    Posted: 19 Feb 2022 04:08 AM PST http://g3xbm-qrp.blogspot.com/2022/02/frustration.html


    Since my 2013 stroke, I have not really been able to do field work. I used
    to enjoy tests at VLF and 481THz "in the field". Instead, I concentrate on what I can do. Our hobby has many faces and there is so much to enjoy. My
    main interests are WSPR and FT8, which don't tax my voice.
    I still enjoy 2m and 70cm activity contests and go on our club net most
    weeks on 2m FM.
    Building things was one of my pleasures, but sadly my eyesight and fine
    motor skills make this very hard. I won't say impossible, but it is now far from easy.

    15m FT8 RX (Saturday)

    Posted: 19 Feb 2022 02:11 PM PST http://g3xbm-qrp.blogspot.com/2022/02/15m-ft8-rx-saturday.html


    At the moment I am monitoring 15m FT8 RX with the 10m antenna. After about
    5 minutes, at 1147z, 38 stations already spotted. 15m is a great band!
    UPDATE 1208z: 87 stations spotted including 2 in South America.
    UPDATE 2205z: 882 stations spotted on 15m FT8 RX. Now QRT.

    Innovations and Trials Licence 8m application

    Posted: 19 Feb 2022 01:42 PM PST http://g3xbm-qrp.blogspot.com/2022/02/innovations-and-trial-licence-8m.html


    Thanks to the generosity of total strangers (thank you all) I now have
    covered the costs of my application to OFCOM.
    My fund raiser is now closed.
    Every penny over the licence costs (a few pounds) is going to charity (any suggestions?) and I do not profit at all from this. To do so would have
    been totally wrong and was never my intention. If OFCOM had just granted me
    a simple NoV, none of this would have been necessary.
    The application is going in today.
    UPDATE 1445z: Apparently an Innovation and Trial licence is £50 per month, which is stupid!! I shall apply for an Innovation and Research Licence that
    is £50 annually.
    UPDATE 2140z: A couple of really nasty comments have been received which I have marked as SPAM and I shall not publish. For the record, (1) nobody had
    to contribute, (2) not a single penny goes to me, (3) my only reason for
    doing this is to further radio propagation research, (4) in the future I
    hope all radio amateurs can gain access to this most interesting part of
    the spectrum.
