TROUBLESHOOTING AND SIGNAL LEVEL GUIDE.
This document will provide a guide to troubleshooting the SR-150
transmitter front end. It starts at the microphone jack, proceeds
through the mic amplifier chain, through the balanced modulator and
to the output of the transmitter 1650 IF amp.
This guide and the signal levels are true only when the receiver is free
of faults and aligned properly.
