    ZS6WAB beacon on 40.675 MHz heard in Europe - 4th to 11th Feb 2022

    Posted: 12 Feb 2022 03:43 AM PST https://ei7gl.blogspot.com/2022/02/zs6wab-beacon-on-40675-mhz-heard-in.html



    During the period of the 4th to the 11th of February 2022, quite a number
    of stations have reported hearing the ZS6WAB 8m beacon in South Africa on 40.675 MHz.
    These are the 8m spots from the DX Maps website... Date & time Spotter QRG

    It's worth noting the times of these reports. The earliest is around 10:30
    UTC and the latest is around 15:00 UTC.
    That is roughly a 4-5 hour window centred on local noon when the sun is at
    its highest.
    It was also interesting to see a report from Nicolas, TT8SN in Chad at 4,300kms. This was likely to have been one hop F2 propagation.
    This is the map of the stations in Europe in more detail...

    Notes...
    1) It's very encouraging to see so many stations listening for and
    reporting a beacon on the 40 MHz band!
    2) Any serious 6m operator on the 50 MHz band will be always looking for sources of information be it on air or online with DX clusters or chat
    forums. Even if someone on 6m in Europe has no real interest in the 40 MHz band, the 8m beacon can be used to indicate that an opening to South Africa
    on 50 MHz may be imminent.
    3) Dave, G0DJA in IO93 square in England reports hearing the beacon with a simple dipole. That is also I believe the most northerly reception report
    of the ZS6WAB 8m beacon to date.
    It also reminded me of the perils of using the Mercator projection flat
    map. When Dave sent me a report, I thought that his location in IO93IF
    would be a good bit further away from the beacon than my location on the
    south coast of Ireland which is IO51TU. However in reality as can be seen
    from the map above which is a great circle projection, I am a little
    further away.
    4) From the 4th to the 11th of February, the solar flux was in the range of
    118 to 127.
    5) It's worth remembering that all of these reports were heard by a person listening on CW. That is probably 10-15dB above what might be possible with
    a digital mode like FT8, Q65, WSPR or PI4.
    6) This nice video shows reception of the South African beacon by Paul,
    G7PUV in the south-east of England on the 4th of February 2022....

    Propagation Mode??... At the moment, the conditions on the 28 MHz band are reasonably good with plenty of East-West F2 layer propagation. This
    suggests the the F2 MUF (maximum usable frequency) on North-South paths is
    up above 30 MHz and into the low VHF spectrum.
    Does it reach 40 MHz at the moment? I suspect it does from the south of
    Europe.
    On some bands, you can be reasonably sure what the propagation mode is. On
    the 40 MHz band at the moment, can we be sure that it's all F2 layer? Is it partially or all TEP related? Is there a Sporadic-E extension at either end
    of the path?
    It would be interesting to see if anyone could hear the beacon at around 20:00-21:00 UTC when there might be evening type TEP. If they could then
    that might suggest openings on the higher bands like 50 MHz and above.
    It would be also interesting to see if stations in the SE of the USA could
    hear this 8m beacon?
