Scanning Basics
This section provides you with background on how scanning works. You
don’t really need to know all of this to use your scanner, but some
background knowledge will help you get the most from your AE125H.
What is Scanning?
Unlike standard AM or FM radio stations, most two-way communications
do not transmit continuously. Your AE125H scans programmed channels
until it finds an active frequency, then stops on that frequency and
remains on that channel as long as the transmission continues. When
the transmission ends, the scanning cycle resumes until the scanner
receives another transmission.
What is Searching?
The AE125H can search for active frequencies. This is different from
scanning because you are searching for frequencies that have not been
programmed into the scanner. When you select frequency bands to
search, the scanner searches for any active frequency within the lower
and upper limits you specify. When the scanner finds an active
frequency, it stops on that frequency as long as the transmission lasts. If
you think the frequency is interesting, you can store it into one of the
banks. If not, you can continue to search.
UNDERSTANDING SCANNING
What is CTCSS/DCS?
Your scanner can monitor systems using a Continuous Tone Coded
Squelch System (CTCSS) and Digital Coded Squelch (DCS) system,
which allows the squelch to open only when the tone you have
programmed with a specific frequency is received along with a
transmission.
