Freie Deutsche Jugend

Badge used by the former "Freie Deutsche Jugend" (Free German Youth, a communist affiliated youth organisation) in the former German Democratic Republic (East Germany/DDR).

I had/have no relations to FDJ (OZ1FDJ now OZ2M), but a nice kind of propaganda :-)


Ham history

VHF license 1979-Jun-13 as OZ1FDJ. HF license spring 1980.

Primary interest is 50 MHz, 70 MHz, 144 MHz and 432 MHz.

I am not QRV on HF. My last HF QSO was on 2001-Oct-28. So do not expect to find me there. The only reason I have a HF capable radio is to use it for my transverters.

Callsign changed to OZ2M 2000-Jan-01, more about who first used the OZ2M callsign.

I am a proud member of PNGonVHF.

The first OZ2M

The OZ2M callsign was first issued to K. L. Ewald, Adelgade 18, Hobro, Denmark. I wish to thank to Bob, W5KNE, for researching the history about OZ2M. Without his work the story below would not have been possible.

OZ2M used a 4 stage c.c. rig on 14,110 kc. and runs about 100 W input. His QSL card can be found on many walls throughout the world. Source: Pacific Radio Publishing Company, Radio magazine 1936.

OM Ewald says that soon his 12-year-old daughter, Kirsten, will have a license and will be on the air under the call OZ2YL. Source: Russian publication? 1937.
