Beacon frequency: 28.245 MHz.

Power output: 2 W

The beacon has been offline for more than a year due to severe problems with the TX and is back on-air since January 2017 with a new TX (Sommerkamp TS-712P). We are sending for a limited period on 28.045 MHz and will switch to the right frequency as soon as the new crystal arrives.

Update: The crystal has arrived. The beacon is sending on the correct frequency 28.245 MHz since July 2017. The quality of the signal has greatly been improved. More information (in german) on the website of our club.

Location is in a small village named "Bomlitz". The region is called "Lüneburger Heide".

License holder of DB0TEN is Michael DH2OAA.

QSL Manager is Jörg DO8HF.

Special thanks to Klaus, DF6AP and Jan, DK1OM for supporting this project!

Reports are welcome!

Repeater frequency: 439.2125 MHz; more information (in german) here.


A short history of the beacon


DB0TEN started in 2010 as a private project of Michael DH2OAA and Martin DO1MF. They realised that no reliable 10 m beacon for propagation tests existed in the north of Germany and Scandinavia. So Michael requested a license at the German license authority "Bundesnetzagentur".


Two problems brought the project to a halt for nearly two years:

1. Michael changed his employer in 2011 and suffered from very heavy workload.

2. The assigned location was no longer available.


After several long discussions, a solution was found.


Many people contributed to the project.

Michael's part of the beacon is the Realistic HTX-100 transceiver, the housing and the concept. He added a compact power supply and a small ATMEL-board for the keyer logic and placed them in a metal case. A little blower running at half speed keeps the temperature at moderate level.

PIC programming was done by Klaus DF6AP.

The vertical antenna from COMET was provided by Martin DO1MF.

Jörg DO8HF gave parts for lightning protection.

Jan DK1OM offered a new location on the roof of his father's house.


This brought new life to the project and the beacon finally went "on air" on June 29th 2012.
