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

depending on the
position of ‘TX

Digital receptions and transmissions will be
indicated by illuminating the ‘
ID
’ 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 position of
the ‘TX Digital’ soft switch. As in Talkback
Scan, the RTX channel and receive
annunciators will be displayed for the duration
of the timer.
The talkback timer can be cleared by making
the held channel invalid. For instance, if a
scan channel is being held, turn scan off.
