Analog Mode Operation

This Chapter provides details on the DVRS Analog Mode of operation.
The Analog Mode assumes the following:
•
APX MSU Programmed for DVRS Operation.
•
PSU programmed for DVRS operation using a Conventional, Analog, non-
ASTRO Personality.
•
DVR Channel used is programmed for Analog (or Mixed) Mode of Operation.
NOTE:
The basic principles of DVRS operation (both Analog and Digital) are as described in the
DVRS Operation Basics Chapter. This Chapter focuses on features specific to the
Analog Mode of operation.

DVR Channel Setup for Analog Mode

To enable Analog DVR operation on a specific DVR channel the Channel Type (in the
Repeater Channel Setup Menu) must be set to Analog. The DVR Tx / Rx Frequencies
as well as the Tx / Rx PL or DPL must be programmed to match the corresponding PSU
settings.
NOTE:
Mixed DVR mode allows Analog DVR operation by switching between digital and analog
modes as described in the Mixed DVRS Mode section. The use of mixed mode for
analog DVRS communications is not recommended since it requires special user
training in order to handle the switching between default digital and temporary analog
mode. Mixed DVR mode should only be used when both analog and digital PSUs are
required to operate on the same DVR channel.

Group Calls

An analog local PSU in DVRS mode can communicate with other analog local PSUs via
an active Primary DVRS if all units are using the same radio channel (full duplex only)
and using matching PL / DPLs. Inbound PSU calls will be repeated on the MSU side
over the currently selected MSU TG / Channel. Outbound calls received by the MSU are
repeated to the Local Analog PSUs.
