3.4 AMS42 - Transceiver Receive Functions
3.4.1 Receive Selection Switches
The receive audio is selected by switching any of the RX switches (white switch bats) UP to connect the
indicated radio to the headphone bus. The AUX position does not have a separate RX switch and is
connected to the headphone bus by rotating the TX selector to the AUX position. See section 3.4.3.1 for
RX volume control.
3.4.2 Transceiver Selection Examples
In the figure below, the right side TX selector is set for transmit and receive operation on COM2. The
Receive function switches are also selected so the right side can monitor COM1 and FM2 transceivers.
Note that FM1 is not selected and AUX cannot be selected by the RX switches.
RX Switches at COM1 and FM2
In the figure below, the right side configuration remains the same. The left side is set up to receive and
transmit on FM1 while monitoring the COM2 transceiver. Note that COM1 and FM2 are not selected on
the left side.
