Most of my recent radio activity has been confined to SWLing and a few local chats on 2 metres.
However today I did a little HF operation and worked 3Z1BLH on 20m PSK. This rather exotic sounding callsign is in fact on Chelminek Island in Poland. Its hard to keep up with callsign allocations sometimes and I wonder why this station didn't have an SP prefix? However I guess the UK allocation with its G's M's and 2's must be confusing too!
