On a 4 wire mic: Assuming the audio is right, next with the mic un-keyed and the meter lead is still attached to the shield, check for continuity zero Ohms to the remaining 2 wires. Uniden's seem to sound the best. Keep in mind that the shielded wire is the audio wire regardless of its color. See the inset in Figure 3. After finding the audio line, cut it at a convenient spot and insert a 4700 W 4. The mic from the 76 has a dynamic cartridge, the type used in stock mics for many years.

Continue jumpering around until you hear a normal receive signal in the speaker. Your email address will not be published. Many times when keying it youll see the Ohmmeter kick up, then slowly settle down to a set value as the capacitors in the mike amplifier charge up.
