[MRCA] PRC-47 low receive audio

[Tim]

Hi Scott - Baring any component failures, you may be OK.  The front panel
"volume control" actually works in tandem with the radio receiver Gain
control.  That is an adjustable Pot (R-54) in the Audio Frequency
Amplifier  module inside next to the HV power supply.  Try turning that Pot
up and see if it improves...
