Notes
Repeater PPI
Enable / Disable
Check box
When enabled, the AVR periodically
interrupts its transmission during
outbound call repeat to check for LPSU
activity. If such activity is detected, the
AVRS can give higher priority to the
LPSU call over the system call.
Repeater PPI is used to
give priority to LPSU
inbound calls over
base-to-portable
(system outbound)
calls.
Conv PPI
Timing
Slow
Fast
Determines the time between
transmitter interruptions during
Conventional outbound calls as follows:
Slow – 2 seconds
Fast – 500ms
PPI interruptions are
heard on the LPSU as
‘clicking’ noise.
Trunk PPI
Timing
Slow
Fast
Determines the time between
transmitter interruptions during Trunking
outbound calls as follows:
Slow – 1 second
Fast – 500ms
PPI interruptions are
heard on the LPSU as
‘clicking’ noise.
Trigger
Squelch
RSSI
Squelch & RSSI
Determines the Receiver Sensitivity
trigger.
STE Type
OFF
+180 deg
-135 deg
+135 deg
Must be programmed to match the
Squelch Tail Elimination type used by
the LPSU on the AVR channel.
RSSI Threshold
Level
-127 to -50 (100)
dBm
Sets the AVR RSSI Threshold level.
Output Power
+20 to +34.75
(+32) dBm
Sets the AVR Transmitter Output
Power.
Bandwidth
Set 1
Set 2
Sets the AVR adjacent channel spacing
(12.5kHz or 25kHz).
Set 1 and Set 2 are
defined on the
‘Frequency Band
Setup’ screen.
Simplex
Frequency
136 to 941 MHz
Sets the AVR frequency.
Min/Max/Default values
will fluctuate based on
the device frequency
and specifications
Mode Steering
Disabled
Tx Only Steering
Tx Steer / Rx
Latch
Tx / Rx Steering
Selects the AVR Steering mode as
follows:
‘Disabled’ = No steering.
‘Tx Only Steering’ = The MSU is
steered to the corresponding mode
determined by the PL of the LPSU
transmission. When the LPSU dekeys,
the MSU returns to the originally
selected mode.
‘Tx Steer / Rx Latch’ = The MSU is
steered to the corresponding mode
determined by the PL of the LPSU
transmission. When the LPSU dekeys,
the MSU stays on the new mode and
does not go back to the original mode.
‘Tx / Rx Steering’ = The MSU is steered
to the corresponding mode determined
by the PL of the LPSU transmission.
When the LPSU dekeys, the MSU
returns to the originally selected mode
after 6 seconds.
