Modifications for the Kenwood M-411
TM-411 Low/No Receiver Sensitivity
Some users of the TM-411 have reported a loss of receiver sensitivity.
This may occasionally be traced to a loss of oscillation in the 2nd
Oscillator, L29, on Unit A. Changing the below listed parts should correct
anly loss of sensitivity due to problems in the 2nd Oscillator.
O A Unit (X44-1600-00) change the following parts:
XTAL L29 to L77-0873-05
C15 to a 1.5 pf cap.
C54 to a 33 pf cap.
