Cool. Thought it may be that, just haven't seen that symptom before. Owner
hasn't had time for me to get back over and try that. Maybe Saturday morning
if I can catch him.

I've seen a kind of similar problem where channels climb up or down by
themselves. I've got a full set oif the tiny switches, unused, that I got
for another guy but he hasn't shown, so I'll put in this one.

Cheers, Danny
