Biography

Ham radio OP since 1982, DOK A07 Karlsruhe in the DARC (German amateur radio club).

My main interests are CW, QRP digital modes PSK31, JT65, JT9, FT8 and FT4 (thanks to Joe Taylor K1JT)
using state of the art SDR transceivers from FlexRadio and Elecraft and SDR receivers from
Elad, RFSpace and WinRadio. I am a FlexRadio Elmer. You can find a lot of my posts and
tutorials at the FlexRadio community page https://community.flexradio.com/flexradio/.

For PSK31 etc. I use HamRadioDeluxe and for FT8, FT4, JT65 and JT9 WSJT-X, which I strongly recommend.

My aim is to work as many countries as possible with my limited antennas and 10 watts maximum power.

I am responible for our local FM/C4FM repeater DB0UK and SysOp for our D-Star repeater DM0WM.
Our hometown Karlsruhe has 2m, 70cm and 23cm repeaters with the digital modes DMR,C4FM and D-Star.

Our DARC club is A07 Karlsruhe, where we meet every Saturday and twice each month
Friday evening.

As a physician (MD) I also am a member of the German Red Cross and the local EMCOMM team,
operating a complete PACTOR EMCOMM station from our club and at home.
We use AREDN to mesh EMCOMM stations using chat, telephone and data transfer.
Our team uses DMR radios to connect to repeaters with their own emergency power supply.

Some years ago I became interested in the Alexanderson generator at Grimeton/Sweden and it's
17,5kHz VLF transmissions. My VLF gear includes a WinRadio G305e, a SDRIQ and a homemade
magloop made out of a bicycle rim. My portable VLF gear is an ELAD FDM-S2 and a Grahn GS-5SE
active antenna with the special Alexanderson ferrite module.

My other hobbies are sailing, photography, electronics, computers, astronomy, genealogy and history.
