Before I get too many more emails, I want to post a correction of something that was in the March 2008 Fed Files column regarding the federal use of Network Access Codes or NAC's on P-25 digital radio systems.
I incorrectly stated that NAC 293 will act as a digital carrier squelch on professional P-25 radio equipment. I should have said that NAC F7E will operate as a digital carrier squelch on P-25 radio equipment, although I have also been told that this only applies to repeaters and not radios in the field.
The NAC value of 293 is what some are calling a "default" NAC that seems to be used by quite a few agencies.
I have to confess that I don't' own any professional P-25 equipment yet, so I rely on the kindness of strangers for this information...
