This is all really useful stuff.
The radio in use is an ICOM A21. So that is similar territory.
I'm gradually formulating a strategy:
1. I'll try the intercom somewhere quiet and see if it works OK.
2. I'm going to buy another headset the same as my current one (I should have done that anyway as I'm always scrounging Stik's spare and that's less than ideal)
3. If this does not solve the problem then I'll sell the PA200 on Ebay and try another make.
Which raises 2 other questions:
1. Anyone know of a decent portable intercom that works with the ICOM A21 ?
and,
2. If Clark headsets are such a pain from a compatability perspective, why are they so popular ? - they sure ain't cheap

Many thanks for your help.
I'm sure Stik would agree to a meet up somewhere.
We are going to the PFA rally so maybe there if not before
