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...

A General Guide to Frequencies
To find the birdies in your scanner, begin by disconnect-
ing the antenna and moving it away from the scanner.
Make sure that no other nearby radio or TV sets are
turned on near the scanner. Use the search function and
scan every frequency range from its lowest frequency to
the highest. Occasionally, the searching will stop as if it
had found a signal, often without any sound. This is a
birdie. Make a list of all the birdies in your scanner for fu-
ture reference.
