Although I am not the radio expert that many of you are, my thoughts echoed those presented by Rich and Cory. Having grown up in Oregon I remember Oregon State Police using low band for many years and one of the main reasons as I understand it was because of the large areas covered by the low band dispatch centers. Likewise, I was last in California two years ago. It seems that I saw many of the CHP cruisers with low band antennas on them. Rich, are they still using low band down there?
I remember quite a few years ago while still a deputy in Central Washington having dead spots in the county using VHF radio let alone any of the higher bands.
I don't know this for a fact, but like Cory I feel it would be less expensive for analog technology and to re-equip vehicles and dispatch centers.
CHP still uses 42Mhz pairs for their communications in most areas. Many Metro areas have recently (past couple of years or so) even begun to repeat their traffic abandoning the semi-duplex base and mobile scheme of old. Very nice for the scanner listener.
They use VHF portables as mobile extenders (many MT2000's). 154.9050 in many areas, PL changes by division.
The exception to the low band use may be San Diego Area CHP. I believe they were playing on the SD County Regional Trunked System with everyone else in the county.
There is a published plan floating around for a statewide trunked system, but, last I heard was not destined for funding anytime soon (couple years ago) and that was before the economic downturn we are apparently in the midst of now...
