Channels and Memories
The radio supports 2 channels: Main, and Guard. The currently selected channel (ie that channel
that the radio will transmit on when PTT is asserted) is determined by the position of the MN/GD,
and G1/G2 switches.
The Main channel supports multiple memory positions, that is, the user can select Main channel
parameters by switching to a different memory position. The radio supports up to 230 memories
for the Main channel.
The Guard channel supports only two memory positions: G1 and G2 these memories are only
accessible via the front panel switches.
Memory Parameters (L1-3,7,9, L2-1,5,6, L4-1)
Each memory has a variety of parameters that may be edited by the user, some are restricted
under certain operating conditions:
Example: while scan is available for any Main channel memory, the user may not set scan
parameters for either Guard channel or for 'shadow' channels on the Main channel.
The user can manipulate the memory parameters by using the editing commands described in
sections 2.2 (Level1) and 2.3 (Level2). User accessible parameters include:
• memory number
• scan list
• text description
• operating mode
• frequency
• squelch mode and squelch mode value
In addition to editing the memory parameters, the user can create new memories or edit all the
parameters of a memory, using the command L2-1. When started, this command displays the
contents of the memory (if currently programmed), or displays the default memory parameters, if
creating a new memory (for Main channel only). The memory parameter defaults can be edited
using the command L4-1.
Operating Modes (L1-3)
The unit supports three operating modes: Analog wide, analog narrow, and P25 digital. In the
analog wide mode, the radio is operating on 25 kHz channel spacing, on both analog narrow, and
in P25 digital mode, the radio operates with 12.5 kHz channel spacing. The user can easily
switch between modes on any memory for any channel (e.g. any Main memory, and both Guard1
and Guard2). Since the squelch modes are not common across analog and digital operating
modes, if you change across these modes, the Squelch Mode will be affected.
The user can select the operating mode using the L1-3 command.
