Hi Mike
The radio is off across all modes. Think maybe its time to send it home for a
checkup. I just don't have a bench thats tight enough to align what needs to be
done ,as explained by some of the guys ,so far. I guess the days of Heathkit
test gear except for boat anchors is over. still looking for a rebuild board
for the swan supply, I found they no longer exist.
thanks

DALE,
is it off on one mode or all of them?

A man with one clock knows what time it is. A man with two clocks is never
sure.
