About Me

Hello everyone,

I am happy to be a radio amateur now (12/12/2023)! I am located in Nuremberg (QTH JN59NK) and I am a member of DARC (DOK B11). I prefer QSL via Bureau - alternatively also via eQSL and QRZ.

I am mainly active using the following callsigns and radios:

• DF0OHM - HF/VHF/UHF - Club Station Of Technische Hochschule Nuernberg Georg Simon Ohm (Kenwood TS-2000X or Icom IC-7300 with 5LPDA8 and T2FD Antenna)
• DD7MB - HF - Personal callsign (Icom IC-7300 with Difona HF-P1 Antenna)
• DD7MB/P - VHF/UHF - Portable operation (Alinco DJ-MD-5X-EG)

I am interested in many modes, especially PSK31, Olivia, CW/Morse, satellite communication, Meteor Scatter, RTTY, FT8, JS8, SSTV and further developments of these modes.

Satellite Ground Stations (SatNOGS)

I operate satellite ground stations at DF0OHM in the SatNOGS network.

All stations use RTL-SDR (Nooelec v5) receivers. A Turnstile antenna (TA-1) and a VHF-Cross-Yagi with tracking are used for VHF. For UHF, a UHF-Cross-Yagi is also used with tracking.

DF0OHM in 2024

I am currently mainly active on HF with DF0OHM.

I have published a small report for this station for the year 2024. You can find it here.

A-SDR and Antennas

Before my amateur radio days, I focussed on receiving radio signals via SDR. That’s why I still like to use my Nooelec SDR sticks for reception today.

I use a MoonRaker groundplane antenna and an Active MLA-30 loop antenna with a HF upconverter (Ham It Up). Sometimes I also use a receiver amplifier, also from MoonRaker. Furthermore I use a HackRF with the ANT500 antenna.

Read more about this on my A-SDR / Independer website.

APRS

I regularly send APRS messages via my LoRa iGate DD7MB (aprs.fi). I also use it to forward messages to the APRS-IS.

I use DD7MB-9 (aprs.fi) when I’m travelling on foot or by car.

HF Propagation

For propagation conditions, especially for QTH Germany, I recommend the weather and propagation forecast by fading.de and the DX propagation map by DR2W.

I also recommend the solar-terrestrial data by hamqsl.com:

VOACAP and KC2G can also be useful to estimate propagation conditions.

I am mainly active on HF at the moment. When I’m active on VHF and UHF, I usually listen on the local FM analogue and DMR repeaters (Brandmeister Network - Talkgroups 26284, 26391).

If you want the message to arrive (reliably), please send it by e-mail.
