Mixed Mode Operation
The receiver and transmitter are capable of operating in analog wide-
band (25 kHz channel spacing), analog narrow-band (12.5 kHz channel
spacing) and APCO Project 25 Digital Mode.
Each channel’s Receive and Transmit Mode can be set independently
as follows:
Mode RX TX
Analog Receive qualied analog
signals only
Transmit analog signals only
Digital Receive qualied digital
signals only
Transmit digital signals only
Mixed Automatically receive qualied
analog or digital signals
Transmit analog or digital signal,
depending on the status of “TX
Digital” switch
Digital receptions and transmissions will be
indicated by illuminating the D annunciator in
addition to the RX or TX annunciator.
Analog receptions and transmissions will be
indicated by illuminating the A annunciator in
addition to the RX or TX annunciator.
Mixed Mode Talkback
If Mixed Mode Talkback is enabled, transmissions initiated while
hold time remains will be in the same mode as the received signal,
if the signal was received on the Ready to Transmit (RTX) channel.
Depending on programming, the RTX channel can be the main
channel, a held scan or priority channel if Talkback Scan is enabled, or
the Priority 1 channel if “TX on PR1” is enabled. TX Mode on the RTX
channel must be set to MIXED.
While hold time after a reception remains,
transmissions will be in the same mode as the
received signal, regardless of the status of the
TX Digital switch. As in Talkback Scan, the
RTX channel and receive annunciators will be
displayed for the duration of the timer.
