I was given the call PA3ABA in 1977 at the time they ran out of PA0 callsigns. So they started a new block with PA3AAA being the first computerized call. It was fun getting on the bands with a PA3 prefix, everyone wanted a QSO. Then after some years they decided to change their policy. PA-PH was allowed with a 2 or 3 letter suffix, callsigns were free to choose but no PA0's allowed. I got myself PA4TU, it sounded nice in CW....
@pg4i @hamchallenge #hamchallenge HC04S. Glad that Jo did all the hard work for me. I previously got the callsign PE1DFF for VHF and up at that time in 1979 when I became 16 yrs of age. After passing the CW exam 3 years later I was issued PA3DSB. No free choice back then and never thought of changing it. So it will stay Double Sideband...
