Trying hard, to convert a decoder from 'old timey' Quik Call (2+2) to Quik Call II; I've got a scheme worked up that will allow sequentially numbered decoder names "Site 18", "Site 19", "Site 20" , "Site 21", "Site 22" and tone plan I'm using takes the tones from the same column; ex. group2: # 1 = 288.5, #0 = 1092.4, ...#8 = 1034.7, #9 = 1063.2,etc.

So #18 would be 288.5/1034.7,
and 19 would be 288.5/1063.2
and 20 would be 296.5/1092.4
and 21 would be 296.5/288.5,
but 22 would be 296.5/296.5 right? WRONG!!

I just can't dig up the rule for doing this; I seem to remember something about a 'diagonal' tone to be used when you have a duplicate like this..If so, how is it used and where does it come from?

According to a spec sheet I have, diagonal tones are 569.1 or 979.9. I suppose it was up to the system engineer which one is appropriate. Both tones can be found within one of the paging groups. Unless your encoder is resticted to a particular code group, I don't see why any other tone couldn't be used.

I'm guessing that you are looking for the diagonal tone which was used when Group Call wasn't needed. Here is how it is set up for the Communication Specialist PE-1000 encoder.

Yes, Andy, that is what I'm looking for; but is the DG programmed in the console I'm using? And is it according to a local engineer's option?

Some of the users pagers have AB/AC (or is it AB/CB?) reeds installed, for first responders...So it's not like a group call;
Man, it's been so long since I looked at a paging plan enough to make proper sense of it....

Thanks..

Usually it matches the PE-1000 format unless the setup technician was a sadist and just wanted to make the next technician's life miserable. What kind of console do you have?

The Motorola tone groups / pagers were normally setup to activate on a A/B and A/C.

Plectron sometimes used a long "B" or common "B" tone which didn't work with a Motorola Minitor II without some field engineering.
