It's fairly rare for me to hear a simplex CQ on 145.500, so after a quick bit of button pressing, I called Paul G4APL/M. It turned out that he was on the A40 between Witney and Burford, some 15 miles away from me. We had a good QSO, with signals getting weaker as I approached Abingdon.
I signed with Paul and was pleased to be called by Alan, G3SLI in Wootton near Abingdon. I occasionally work Alan on 70MHz FM and it had been quite a while since we spoke. I got the impression speaking to Alan that he hadn't made too many QSOs recently - so a bit of simplex activity was welcome. We could also hear that Paul, G4APL/M was working a portable station closer to him in Burford on another frequency. I told Alan that I'd come across his callsign in connection with his activities frrom Gibraltar on 70MHz in the early 1960s when I was looking at Mike, G3JVL's QRZ page the other day. A really nice QSO with Alan, talking about aerials and VHF propagation.
It struck me that unless Paul had made his CQ on 145.500 - those great QSOs wouldn't have happened. A great reminder that activity really does breed activity and that I should call CQ on simplex myself more often!
