Re: FT-101ZD MK2 poor sensitivity ..

 

One thing you could try is to gently work the ATT switch back and forth like 50 times. That often works for a little time.?

Thank you for the effort Chuck,

The 'Trap' is located on the Trimmer Board 'A'

From my observation the Marker Signal does not go through the ATT switch but must be fed (as Don suggested) somewhere past it but before T1.

So that (as you said) would only leave the ATT switch or the 'trap'. Maybe a cold solder joint or wire that came 'off' ..

Well, at least I know where to look now and I've ordered 2 cans of contact cleaner.

Attached a video of the 'Marker' :)
