A General Guide to Frequencies
This is very useful when you want to narrow the scan in
areas where numerous entities utilize the same trunking
system. For example, if the police department, sheriff’s
department, fire department and EMS all use the same
system in your area you can program the identical trunk-
ing frequencies on 4 separate banks. Then by manually
storing their respective group IDs into corresponding
banks (i.e. police IDs in bank 1, sheriff’s IDs in bank 2,
fire rescue IDs on bank 3 and EMS IDs on bank 4) and
setting the banks to the closed mode, you can choose
which service you want to listen to. (See “Turning Chan-
nel-Storage Banks Off and On” on Page 41.)

A General Guide to
Frequencies
Reception of the frequencies covered by your scanner is
mainly "line-of-sight." That means you usually cannot
hear stations that are beyond the horizon.
