[Scan-DC] Programming two trunking systems

[Doug K.]

All,

I'd like to toss out something for discussion... last night was reading on 
the ARC 250 software yahoo group, and I think it was there that I saw an old 
thread about trying to program two trunking systems into the same bank on a 
Uniden trunking scanner.  The consensus was that it can't be done (at least 
so that the scanner will scan both)... at least I think that's what I saw 
and understood!  (I'm still green at this trunking business!)

However, comma... I submit to you the following situation - apparently, the 
radios in Montgomery County fire apparatus can be used to talk to other 
jurisdictions - so, what if one programs those frequencies and talk groups 
into the Montgomery County bank of the scanner?  I would guess that this 
should work if the other jurisdiction is also an APCO-25 800 MHz system.  
Seems as if then, they should be received from the Montgomery County point 
of view, if ya know what I mean... ie, if a Montgomery engine runs into 
Frederick or Howard County and is assigned a channel like 15-Echo or 
15-Delta (I think those are ones I have heard them use for one or the other 
of those locations), the radio should pick it right up, right?

Am I making any sense?  Does anybody understand this?  Or have I missed a 
basic premise somewhere (very possible!)...

Thanks-

Doug
