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)
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.
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.
In previous years, I had recorded the number of times I heard the German beacons on 28 MHz

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.
