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, on the
frequency of the Ready to Transmit (RTX) channel. Depending on radio
state, 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.
