[FedCom] VTAC

[Mark Cobbeldick]

Who came up with these names?  (VTAC, UTAC & ITAC)  Are they radio
hobbyist designations, or something official?

I used to run a large public safety radio system, and neither I or any
of the (radio) folks currently in state or federal law enforcement I
checked with this morning had ever heard of these 'designations'.  They
appear to be of a local naming convention...

Regarding the 800 MHz Mutual Aid frequencies, as designated by the FCC,
those have always been referred to as NPSPAC (National Public Safety
Planning and Advisory Council) Mutual Aid channels, not " ITAC ". 
These "ITAC" names also appear to be of a local naming convention.


The Alpha name tags that I have seen usually shown in the display of
radios is:

"NPSPAC-C" or sometimes simply "CALLING"
"NPSPAC-1" or sometimes simply "TAC-1"
"NPSPAC-2" or sometimes simply "TAC-2"
"NPSPAC-3" or sometimes simply "TAC-3"
"NPSPAC-4" or sometimes simply "TAC-4"

(NOTE: Most radios only support up to an 8-character alpha numeric name
tag.)

If you go to APCO's website, they do not even use the " _TAC "
designators.
