PROGRAM SEARCH
This function tunes the receiver through all frequencies between two specified
frequency limits in predetermined step size, looking for active frequencies.
The search instructions may be programmed into "search banks".
There are 40 search banks, numbered from 00 to 39.
Search banks can be searched either individually or in a group of linked banks.
There are 10 search groups, numbered from 00 to 09.
It is crucial to correctly set the SQUELCH level for the search function to operate.
In order to do that, tune to a none-active frequency and increase the squelch level
to the point where the sound will mute. We want the squelch to only open when the
signal becomes active.
Note: Search mode is extremely effective for AM & NFM use in the VHF and UHF bands.
Searching the shortwave bands is usually ineffective due to the relatively high background
noise.
