The programming of the Motorola units is suposed to be exactly the same as it comes out of the software, but I learned a long time ago that Motorola units, especially portables, have a variance between units (quality control?) and no matter what the programmer does, it seems that the radios have a mind of their own.
As I understand it from chatting with a number of GBPD officers over the years, they DO have a VHF radio in each cruiser, but they are under orders to keep it turned off unless AUTHORIZED to do so under special circumstances, by the shift commander. I guess having more than one radio on at once might be a distraction - and because the 800 equipment "works SO well", that they need FULL ATTENTION on the 800 equipment to TRY to hear what's going on. State Patrol units in this general area have three radios going at once and they don't seem to have issues. GBPD still has a repeater on 155.130 and it was a good system. Portables worked all over the place properly and if they got into a chase which went into the county, they would still have reliable comm 30 miles away. With the 800 system, they get 5 miles away from the last tower in their jurisdiction, at that's all, folks...no comm.
They DO have the capability at this time to use the MARC repeater for interagency coordination and operations... but it is only used during "important dignitary visits" to the area for convoys and usually isn't used at all for anything else. The letters stand for Mutual Aid Radio Channel - and it just sits there unused most of the time. The operating protocols are such that it could be utilized for any regional multi agency purpose, but evidently, it is conveniently forgotten about.
