Re: FT-101ZD MK2 poor sensitivity ..

 

Do you have a signal generator? If you do, inject a signal at the point where you have both the Red and Green Arrows marked and see if that is normal sensitivity. If it is, work back to the antenna connector and see where you are losing it.?

Removed both covers and traced the RX signal line via the ATT switch to Trimmer Board A.
I measured continuity between 'RX Antenna In' -> Switch -> choke and it was fine.
The switch is working as it should.

I also traced the marker signal and it is 'injected' before the choke together with the RX signal line.
