1. SGnn nn: 00 ~ 19 (Search group number) (00: default)
(Note: The SG00 is not available for search link.)
2. DLnn nn: 01 ~ 99 (Search delay time, in 0.1 sec.) (default: 20)
When a signal is lost, it will resume search after the preset delay time.
3. FRnn nn: 00 ~ 60 (Timer search, in 1 sec.) (default: 00  Off)
When a signal is received, it will resume search after the preset time.
4. ASn n: 0, 1
0: Auto store Off (default)
1: Auto store On
When Auto store is set to On, the received frequency will be registered to
Search bank #40.

4-2-4 Search frequency list
There are 1024 channels of search memory in the AR2300. By executing the FL
command, 40 channel data can be displayed.
FL
FLn n: 0 ~ 4
n: 0 Displays the latest 40 channels (frequencies may duplicate.)
1 Displays the latest 40 channels (frequency not duplicated)
2 Displays 40 channels with the strongest signal
(frequency may duplicate).
3 Displays 40 channels with the strongest signal
(frequency not duplicated.)
4 Displays most frequently detected signals.

4-3 FFT search
FFT search differs from regular scanning methods (one frequency / step after the other) in that it provides
a spectrum [image] up to 10MHz wide, sampled 15 times per second. Although the search bank basic
settings for normal search and FFT search are done the same way (for Low Frequency, High Frequency,
and text settings), in FFT search the following parameters must also be set.
