Understanding Scanning

Conventional Scanning

Conventional scanning is a relatively simple concept.

Each group of users in a conventional system is

assigned a single frequency (for simplex systems) or

two frequencies (for repeater systems). Any time one

of them transmits, their transmission always goes out

on the same frequency. Up until the late 1980s, this

was the primary way that radio systems operated.

Even today, there are many 2-way radio users who

operate using a conventional system:

•

Aircraft

•

Amateur radio

•

FRS/GMRS users

•

Broadcast AM/FM/TV stations

•

Many business radio users

When you want to store a conventional system, all you

need to know is the frequencies they operate on.

When you are scanning a conventional system, the

scanner stops very briefly on each channel to see if

there is activity. If there isn’t, the scanner quickly

moves to the next channel. If there is, then the

scanner pauses on the transmission until it is over.
