Biography

Kiitos mielenkiinnosta profiiliani kohtaan. Erityisesti Suomalaiset... 468 sivun latausta elokuussa 2025..


Thanks for looking up my callsign on QRZ. I'm a 60 years old man. Licensed as a Ham in 2012, been active on many kind of radio hobby since 1977. Working all bands from HF to UHF bands both at my home station on SSB and FT8. My main interest for a long time has been to work with bands in as many US counties as possible, and of course new countries.


I work with an average power of 80W. No! linear amplifier in use.. Although I have heard malicious "old timers" claim so. When I am in the same positions in certain listings on the FT8 DXCC listings even though I have not! invested thousands of euros in antennas or a tower... not to mention that amplifier.
I live in an apartment building so its height of about 18 meters from the ground is my "tower"

73 OH1EDK look forward to meeting you on the air.
