Trunk Scanning; Trunking Delay; Locking Out Talk Group Ids - Radio Shack 20-163 User Manual

Trunk Scanning

Trunk Scanning
In each bank, you can mix conventional channels and frequencies
in a bank. However, you can scan only one trunking mode at a time,
either EDACS, Motorola, or LTR.
Press SCAN. The scanner scans through unlocked channels in
active banks. To focus on trunk scanning, you can turn off banks
that contain only conventional channels. To change the scanning
direction, press or .
For Motorola channels, your scanner displays the Talk Group ID
memory location, received frequency, voice channel (VC), and the
Motorola ID number.
Notes:
• Your scanner automatically mutes the audio while it decodes
control channel data. However, we recommend you turn SQ
clockwise and leave it set to a point just after the hiss stops.
This lets the scanner quickly acquire the data channel.
• For Motorola trunking systems, more than one talk group
can transmit at a time. If you manually tune the scanner, you
will hear the talk group on that channel, but the display will
alternate between all active Talk Group IDs.
• For EDACS and Motorola (above 406 MHz range), the scanner
monitors the control channel between each transmission to
identify talk groups. For some Motorola (under 512 MHz range)
and LTR systems, the scanner uses the subaudible data sent
with each transmission to identify talk groups.

Trunking Delay

You can set a Talk Group ID delay separately from the channel
delay. When active, the scanner checks the Talk Group ID for the
delay time when a transmission ends.
