PRC-77 A18 5.6-MC Amplifier Module

A18 5.6-MC Amplifier Circuit Module (IF Amplifier)

The Circuit Module A18 is the 5.6 MHz amplifier (5.6 MC Amplifier) for the PRC-77 / RT-841 radio set. It is a core assembly in the receiver path, amplifying the signal at the second intermediate frequency (IF).

A defect in the A18 often leads to poor receiver sensitivity, noise, or a complete loss of signal, as the necessary amplification of the second IF stage is missing.
