XTR VHF Rx sens
XTR VHF Rx sens
I have a VHF XTR 70-1340B with receiver sens of 1.5 microvolts. Is there any tweak or what could cause this?

suspect q201
try first: inject signal via loose wire to various locations in front end see if no improvement on the input side of q201
try second: carefully slacken screws around front end, may be bad feed through
try third; wiggle components in front end using plastic tuning tool, if jumps/improves instantly de-power and solder areas
Thoroughly re-tune front end according to manual

Hello Techmedic. Thanks for the reply. It sounds like good advice. I will try your suggestions next time I see the radio.
