I hate to sound silly, but can anyone explain what each of those settings do? for example im guessing A-B = alert if tone A and B are met. And if a previous post is correct, AB/CD = alert if A and B or C and D are met. I've actually been looking for an explantion for quite some time by doing searches on here and batlabs.
thanks
I'm going to attempt to explain this. This is one of those things, for me, that are easily understood but hard to explain.
A-B =
Tones A & B are met
A-B/A-C =
Tones A & B OR Tones A & C are met
A-B/C-B =
Tones A & B OR Tones C & B are met
A-B/Long B =
Tones A & B are met OR Long Tone B is met
A-B/Long C =
Tones A & B are met OR Long Tone C is met
A-B/A-C/Long C =
Tones A & B are met OR Tones A & C are met OR Long Tone C is met
A-B/Long B/Long C =
Tones A & B are met OR Long Tone B is met OR Long Tone C is met
A-B/A-C/Long B/Long C =
Tones A & B are met OR Tones A & C are met OR Long Tone B is met OR Long Tone C is met
A-B/A-D/C-D =
Tones A & B are met OR Tones A & D are met OR Tones C & D are met
A-B/C-D =
Tones A & B are met OR Tones C & D are met
A typical tone-out system is 1 second Tone A followed by 3 second Tone B.
Long tones are 8 seconds long, and are only 1 tone.
The tones have to match in order; so for example, setting your Quick Call for A-C means the tones need to match in the order A first, and C second.
A-B/C-B would be for a common B tone. This is what I use for my station's fire and EMS tones. This will match both the A & B tone and the C & B tone in those orders.
Let's say, for example, your Fire tones are 100.0 and 200.0, and they are set off in that order. 100.0 would be tone A, and 200.0 would be tone B. Now let's take that further and say your Ambulance tones are 150.0 and 200.0 Since the 200.0 is in both of your tone sets, it can be used as the "common" tone. You would select "A-B/C-B" and 150.0 would be used as the C tone. Putting in the Quick Call would look like this:
A = 100.0
B = 200.0
C = 150.0
This will now alert your radio for both sets of tones.
I hope this kinda helps. If not, send me a PM and I'll try to explain further.
