Hi Nicola,
Many thanks for the very fast reply. Maybe CQ CQ QRPCLUB.ORG DE... could be cut down a little? I'm very old, not very bright and might forget where I an in the middle of my cq call!!
How's about CQ CQ QRPCL DE... ? (Might be poor choice. Under bad condx CL may make listeners think station is declaring closedown!!!)
The GQRP-Club call of CQ CQ GQRP DE... is well known and, I think, effective, as is the ARCI one. Four club designator characters seems a commonly used pattern. Short and snappy is good, especially in QSB.
I'm short on ideas: QRPC, QCLUB, QRPCL is all I have come up with so far as mere suggestions. I believe we need something unique, short, snappy, easy to read under poor conditions which will in time become instantly recognisable across EU and possibly the world.
Just my opinion,
Vic GQRP #3078, ARCI #6211
