Hopefully, you are looking me up because you hear / see me on the air!


From 13. to 22. August 2019 I was qrv from the campsite in Barum in lower saxony, locator JO53ei.
Due to problems with other non-standard callsigns in FT8, I am often do not append the suffix '/P' to my callsign.



Please call me by my nickname Ham. I was born in 1961, licenced since 1976. I have made a radio break from 1981 till the beginning of 2012.

SSB and CW do not belong to my preferences, with very rare exceptions I am not on air in these modes. I prefer the digital modes.

Because the digital modes are low-power operating modes, I will transmit with a maximum power of 50 watts. I use and have no aditional amplifier.

If you can not hear me when I call you, then you have too much output power :-( - and this is often the case.
Perhaps this is the explanation, why I have listened so far only American and Japanese HAMs at 50 MHz and did not reach ...

If I answer your CQ-call in FT8, JT65 or JT9 please do not forget to send a "RRR" or , "RR73" otherwise our QSO is invalid. It is simple: No "RRR" or no "RR73", no QSL-Card.

And please, please do not be so rude and finish our QSO without 73! So much time you should have for our QSO.

Note, tip: If you use JTAlert from Laurie, VK3AMA, please click on "Receiving Text Messages" in the settings (Web Services). So you can receive text messages from other JTAlert-users (for example, from me :-) ).

Germany is not realy a rare country. Everyone has worked a german station on every hf band. So sometimes I ride a little devil and call on 10m for hours in JT65 "CQ" with only 1 Watt and look at and where all over the world my signal is heard and who does not answer... :-)

Caravan camping in Barum in lower saxony, Locator JO53ei, is one of my other hobbies. Some times you can hear / see me portable from the campsite.

We already had a contact? Please feel free to call me again. Maybe you have a new antenna, maybe the current conditions are different. There is always a reason for a new qso :-)


I do not collect QSL cards anymore. But if you send me your QSL card, I would be happy to send you my QSL card.


Worked DXCCs:


Equipment right now:

- Main TRX: HF base station Yaesu FTDX101MP
- BackUp TRX: HF base station Yaesu FT-950
- homebrew Interface for FT8, JT65/JT9 and PSK
- Intel dual core PC with windows 7, HRD, Digital Master 780 and WSTJ-X
- Digital SWR/wattmeter to watch VSWR and output power
- ZS6BKW-Dipol, a computer optimized version of the G5RV multi band antenna for 80 - 12 meter, hung up in north-south direction (bad for Alaska, Hawaii and South Africa)
- MFJ-926B automatic antenna tuner for the ZS6BKW
- an 15-meters long vertical wire in a tree with the SG 230 automatic antenna tuner for 160, 80 & 60 meter. The ground system is poor (two earth rods plus a small radial field). Most of the transmitting power is converted into heat.
- since 21 February 2019 I have a inverted vee full size dipol for 60m. An antenna I can recommend.
- an end-fed half-wave length antenna for 15 meters
- Sirio2000 5/8 lambda groundplane for 10 meter
- horizontal polarized omni directional high selective narrowband halo-antenna for 6 meter

- Yaesu FT-897 for the campsite

- Alinco DR-605 for 144 MHz and 433 MHz
- Diamond X300 vertical dualband base antenna
