Keep your memory banks tidy - for best scan speed
In order to achieve the maximum scanning speed, it is advisable to keep all
similar frequencies and modes grouped together within the memory banks.
The greater the frequency change between memory channels, then the further
the receiver’s VCO (Voltage Controlled Oscillator) has to travel and the slower
the scan rates. Similarly, when many changes of mode are called for the more
switching has to be accomplished and the scan speed may be reduced.
Memory channel data may be entered in duplicate into several channels.
This will ensure the channel data is scanned more frequently to increase
the chances of activity being detected.
Limitations of SCAN mode
Should a number of different modes and wide range of frequencies be used,
then the SCAN process may be affected by noise or differences in squelch
characteristic on some frequencies and modes.
To help provide the best operation of SCAN, additional facilities have been
provided when in EXPERT status. Should you listen to noisy frequencies or
bands containing carriers, make liberal use of the AUDIO and FREE scan
parameters.
10-4 SCANNING a memory bank...
Let’s assume that you wish to SCAN the contents of memory bank “A”
(channels 00-49) which have been previously stored with memory data.
There are two ways to start scanning:
Firstly
From “VFO” or “SEARCH” modes: Press [SCAN] to enter “MEMORY
RECALL” mode then press [SCAN] again to start scanning.
From “MEMORY RECALL” mode: Press [SCAN] once only to start
scanning.
Secondly
From “VFO” or “SEARCH” modes: Press [FUNC] [SCAN].
The legend “SCAN” is displayed on the top left of the LCD to indicate that the
SCAN process has been initiated.
When SCAN has been selected, ALL MEMORY CHANNELS WHICH
CONTAIN DATA in the memory will be SCANNED irrespective of mode and
frequency. ANY BLANK (empty) MEMORY CHANNELS which contain no data
will be ignored (skipped).
