Thanks Joe & Guy. I've had a look at the schematic and that makes sense. I'll have a look for the 5V on the PTT IN connector and if it's missing, I'll trace it back. I'll take the K3 apart tonight and make a start. If it turns out to be an open RFC, that'll be a simple fix.
Thinking back, I had an RFC go open on my K1 at one stage way back, for no apparent reason. Took me a while to find it because at the time, I really didn't think RFC's were that fragile and that thew me off. Anyway, I learnt a lesson. Perhaps the same one here... we'll see. Thanks for the advice.
