    German beacons heard on 28 MHz in 2021

    During the 2021, I did many scans of the 28 MHz beacon band from about
    28.160 to 28.340 MHz. This post is about the number of days that I heard
    one of the 10m beacons in Germany.

    The map above shows the distribution of 28 MHz beacons in Germany. Note
    that the DB0MFI and DM0AAB beacons were off air in 2021.

    The chart below shows the number of days in 2021 that I heard a German
    beacon on 28 MHz...

    I should point out that I did a lot fewer scans that previous years.
    However, you can still see the beacons that were the easiest to hear.
    1) DL0IGI with its 50 watts into a vertical antenna was heard on 14 days
    and is easily the most consistent German beacon here in Ireland.
    2) DK0TEN (10w GP) and DB0TEN (2w GP) were at 9 and 10 days respectively.
    Every year, these two seem to have almost the same number of recordings.
    (Note - GP is a ground plane vertical antenna)
    3) DB0BER (5w) was heard on 9 days. For whatever reason, it did seem to be
    a bit easier to hear in 2021.
    4) DL0UM has 4 watts into a vertical dipole and was heard on 7 days.

    5) DB0FKS was heard on just 1 day but this can be easily explained due to
    the fact it has just 1-watt into a small DV-27 vertical antenna (i.e. a
    loaded mobile whip).
    In terms of distance, the German beacons are about 1,200 to 1,500 kms from
    my location in Ireland.


    In previous years, I had recorded the number of times I heard the German beacons on 28 MHz
    2019 post HERE
    2020 post HERE
    The reports don't really seem to show any advantage propagation wise if the beacon is in the north or south of Germany or if it's slightly closer or slightly further away. The key difference between beacons from my
    perspective is the power and antenna of each one.

    German 28 MHz beacons... These are the current ones as of the end of 2021

    28.205 MHz - DL0IGI - JN57MT - 50w Vert
    28.210 MHz - DB0FKS - JN49IT - 1w DV27 GP
    28.245 MHz - DB0TEN - JO42UV - 2w GP
    28.257 MHz - DK0TEN - JN47NT - 10w GP
    28.265 MHz - DB0ANN - JN59PL - 5w Dipole (Used to be DF0ANN)
    28.273 MHz - DB0BER - JO62QL - 5w
    28.278 MHz - DM0AAB - JO54GH - 10w GP (Off Air - Last spot on DX-Cluster
    Sept 2020)
    28.279 MHz - DB0UM - JO73CE - 4w Vert Dipole
    28.285 MHz - DB0MFI - JN58HW - 9w GP (Off Air - Last spot on DX-Cluster
    Sept 2019)


    Methodology notes...
    1) The equipment used for reception was a Kenwood TS690 transceiver with a vertical half-wave antenna. The take off to the east towards Germany is
    good with no obstructions.
    2) All beacons must be positively identified before I post them on DXMaps
    which in turn puts them on the DX Cluster.
    3) The mode of propagation for all signals heard was Sporadic-E.
