could still be poland as 3Z0MM and not 3C0MM
my 2 cents
3Z0MM Poland flag Poland
POLISH RADIO AMATEUR CLUB STATION SP3KFH
QSL VIA SP3JHY
"Z" not "C"..boith sound same on ssb especially with an acsent ;-)
Thanks, Paul. You hit the nail on the head. I just pulled the old and faded logbook out and in the comments field it has the QSL route as SP3JHY.
