Transmit Interlock
When two transceiver modules are installed, the TRANSMIT INTERLOCK pin can be connected
to reduce “break-through” (noise being heard as the squelch opens) in one COM radio when
the other COM radio is transmitting. The PTT IN signal (Pin 15) is connected to the TRANSMIT
INTERLOCK (Pin 18) of the other radio, as shown above.
Dual Transceiver Module to SV-INTERCOM-2S Harness Construction Notes
Shielded cable between transceiver module #1 Pins 1 and 2, and SV-INTERCOM-2S Pins 1 and
14:
• This cable consists of two wires plus shield.
• Use one of the wires to connect transceiver module #1 Pin 2 to SV-INTERCOM-2S Pin
14.
• Use the other wire to connect transceiver module #1 Pin 1 to SV-INTERCOM-2S Pin 1
(see instructions below - Terminating Shielded Cables to Pin 1 of SV-INTERCOM-2S).
• On the transceiver module #1 end, continue the shield as far into the connector as
possible until you're forced to pare it back to access the two inner wires. Put some heat
shrink tubing over the shield to keep it electrically isolated - the shield at the
transceiver module #1 end of this cable is not electrically connected at transceiver
module #1.
