Steve,
Here's something that I've posted before that may be helpful:
With respect to conventional frequencies, there are SYSTEMS which contain one or more GROUPS. A GROUP contains one or more channels. For each channel you enter the frequency, alpha tag, and various other parameters that relate to that channel. There are no sites for conventional channels.
SYSTEM 1
.....GROUP 1
..........CHANNEL A
..........CHANNEL B
.....GROUP 2
..........CHANNEL C
..........CHANNEL D
SYSTEM 2
.....GROUP 1
..........CHANNEL E
..........CHANNEL F
SYSTEM 3
.....GROUP 1
..........CHANNEL G
With respect to trunked systems, there are SYSTEMS which contain one or more SITES and one or more GROUPS. In each SITE, you enter the frequencies for that SITE. For each GROUP you enter one or more TALKGROUP IDS. For each TALKGROUP ID you enter an alpha tag and various other parameters that relate to that talkgroup.
SYSTEM 4
.....SITE 1
..........FREQUENCY 1
..........FREQUENCY 2
..........FREQUENCY 3
.....SITE 2
..........FREQUENCY 4
..........FREQUENCY 5
..........FREQUENCY 6
.....GROUP 1
..........TALKGROUP ID 1
..........TALKGROUP ID 2
..........TALKGROUP ID 3
.....GROUP 2
..........TALKGROUP ID 4
..........TALKGROUP ID 5
SYSTEM 5, etc.
System/Site Quick Keys (SQKs) allow you activate and deactivate systems or trunked sites for scanning. For conventional systems, the SQKs are set at the system level. For trunked systems, the SQKs are set at the site level. There can be more than one system or site assigned to a SQK.
The single digit SQKs are toggled between active and inactive by pressing the corresponding key on the keyboard. The two digit SQKs are toggled between active and inactive by pressing the ./NO key followed by the two digits on the keyboard.
The display
S0:1234--7**0 indicates that SQKs 1, 2, 3, 4, 7, and 0 are active; SQKs 8 and 9 are inactive; and SQKs 5 and 6 are unassigned.
S1:12---678** indicates that SQKs 11, 12, 16, 17, and 18 are active; SQKs 19 and 10 are inactive; and SQKs13, 14, and 15 are unassigned.
Etc. to S9:12345678790
Each system can have up to 10 Group Quick Keys (GQKs). The indicator for the GQKs is the line below the SQK line and works the same way except that it only has ten possible values and therefore is only single digits. There can also be more than one group assigned to a GQK.
GQKs can be toggled active and inactive by pressing FUNC and the keyboard number while the scanner is scanning the particular system which contains the groups that you are controlling.
If you use software to program your scanner, you can assign the SQKs and GQKs as you set up your programming and can also set the initial state of the SQKs and GQKs.
