    10m FT8 RX

    Posted: 20 Jun 2021 02:30 PM PDT http://g3xbm-qrp.blogspot.com/2021/06/10m-ft8-brx.html


    There is widespread Es on 10m this morning. A few moments ago (it is now
    0917z) I turned on 10m FT8 RX with the FT817ND and the tiny indoor loop antenna. Already, 49 stations have been spotted.
    UPDATE 0948z: 85 stations spotted on RX.
    UPDATE 1214z: 198 stations spotted on RX. The furthermost is VO1CH
    (3737km).
    UPDATE 1604z: 325 stations spotted on RX.
    UPDATE 1904z: 467 stations spotted on RX with the furthermost PY5BH
    (9903km).
    UPDATE 1954z: 514 stations spotted on RX today. See map.
    UPDATE 2130z: 547 stations spotted today. Soon QRT.

    Since about 0910z, I have been on 10m FT8 RX. So far, 39 stations spotted
    on RX with the furthermost ZS1J (9744km) in the Western Cape, South Africa. UPDATE 1809z: 124 stations spotted on 10m FT8 RX. Interestingly, nothing
    from North America. Furthermost was VP8LP (12773km) in the Falkland Is.

    Antennas for 10m

    Posted: 11 Oct 2021 01:25 AM PDT http://g3xbm-qrp.blogspot.com/2021/10/antennas-for-10m.html


    10m is waking from its slumber: after several years when it has been more
    like a VHF band, it is again a great F2 DX band. In recent days it has
    opened well to North and South America.

    One of the great things about this band is antennas are small and even a
    short distance above ground is significant in terms of wavelengths. CB half wave verticals can work well on 10m and a dipole is very small.
    In the past I used a small wire halo which I called the Homebase-10 as most parts could be got from the local hardware shop. It has been on the blog
    before but with 10m "waking up" now might be a great time to have a go.

    It is now 1000z. For about 10 minutes, I have been on 10m FT8 RX. So far, 8 stations have been spotted.
    UPDATE 1212z: 148 stations spotted with the furthermost VK6AS (14459km). UPDATE 1935z: 569 stations spotted. Both North and South America are
    coming through. Today has been excellent on 10m FT8.
    UPDATE 1955z: 570 stations spotted on 10m FT8 RX today.
    UPDATE 2230z: 630 stations spotted. QRT soon.

    Overnight on 160m FT8 RX

    Posted: 13 Mar 2022 03:05 AM PDT http://g3xbm-qrp.blogspot.com/2022/03/overnight-on-160m-ft8-rx.html



    Yet again I was on 160m FT8 RX overnight. 283 stations were spotted. See
    map. As the night before, plenty of stations spotted in the USA. Antenna
    was the 10m end fed untuned.

    My 10m FT8 RX was turned on at 1240z. It is now 1252z, and, so far, 6
    stations have been spotted. on RX.
    UPDATE 1448z: 59 stations spotted today on 10m FT8 RX.

    5.17kHz loading coil

    This was a photo from 5 years ago of the 5.17kHz loading coil at DF6NM.
    Some remarkable distances have been spanned by amateurs at these VLF frequencies.

    So far today, I have received loads of stations on 10m FT8 RX despite most
    of the antenna being on the ground awaiting the erection of the 8m dipole.
    I notice these were not being uploaded to PSKreporter for some reason, so I shall restart WSJT-X in case this is at fault.
    UPDATE 1521z: I did a resync to internet time and restarted WSJT-X: still
    no spots on PSKreporter.
    UPDATE 1530z: All now seems well, with 10 stations recently uploaded. This will remain a puzzle. All uploads relate to stations spotted in the last 20 minutes.
    UPDATE 2022z: 208 stations spotted with much of the 10m antenna on the ground!! No spots reported for some reason until mid-afternoon. QRT soon. UPDATE 2105z: QRT.

    OFCOM statement about UK 8m permits

    Posted: 31 Mar 2022 08:12 AM PDT http://g3xbm-qrp.blogspot.com/2022/03/ofcom-statement-about-uk-8m-permits.html


    This statement by OFCOM about UK 8m operation has appeared in many places
    and the RSGB has made a statement. I have re-read the OFCOM statement many times as I have my licence.
    Now, I am no legal expert and what follows is my interpretation, but....
    I think the RSGB is wrong.
    My reading and re-reading of the OFCOM statement and my amateur radio
    licence leads me to these conclusions:
    1. OFCOM does not want to release any 8m spectrum for radio amateurs. Personally I think this is stupid when they could have released just 5 kHz, digital modes only, at 5W, no contests, by NoV, on a strictly non
    interference basis. Surely self training is what our hobby is all about?
    2. As long as those operating on 8m hold an amateur radio licence and
    callsign and are receiving crossband reports from other radio amateurs
    using the frequencies only allowed in their licence schedule, I cannot see
    this is illegal. Yes, those working crossband to 8m non radio amateurs
    licenced under T and I conditions would be illegal.
    3. Inter-working other stations duly authorised to operate on 8m is legal
    in the UK. Working those in other administrations is a matter for those administrations.
    These are my personal views, not legally binding views. You need to seek
    your own legal position.
    See http://www.southgatearc.org/news/2022/march/rsgb-statement-concerning-40mhz-in-the-uk.htm#.YkV-BIrMLrc
    UPDATE 1512z: I think OFCOM really wanted a "light touch" on this. As the RSGB sought clarification, they had to answer. The RSGB interprets this differently to me.
