Hot Microphone Function

In the Hot microphone state, only microphones whose

PTT switch is pressed can send modulation signals in the
environment in which several microphones are connected to
the transceiver in parallel.

In the Normal microphone state, if the PTT switch on one

of the microphones is pressed, modulation signals are sent
from all microphones.

 Circuit description

Hot microphone operation can be performed by cutting

the jumper (JP1).

If the jumper is not cut (Normal microphone state), bias

voltage is always applied to the microphone element (Q3 is
always ON) and if the microphone mute of the transceiver to
which the KMC-35/36 is connected is released, modulation
signals can be sent even when the microphone PTT switch is
not pressed.

If the jumper is cut (Hot microphone state), bias voltage is

applied to the microphone element only when the PTT switch
is pressed (Q3 turns ON only when the PTT SW is pressed),
and modulation signals cannot be sent when the microphone
PTT switch is not pressed.
