Programming Motorola VHF and UHF Trunking Systems
Your scanner is capable of receiving Motorola trunked radio systems operating in the
VHF and UHF bands. To monitor these systems it is necessary to program the scanner
with three additional parameters, the
base frequency
,
step
and
offset.
Hint
•
Base frequency, step and offset vary for each individual UHF trunking system. You
can get information about these frequencies for the trunking system you want to scan
using
www.trunkscanner.com
, other Internet sources, or locally published
guidebooks.
•
Systems with multiple channel ranges can be programmed using PC application
software.
