Last weekend while travelling through Colorado, I stopped in Grand Junction in an attempt to resolve the question regarding frequencies used by Grand Valley Transit. I programmed my scanner to receive 461.125 cited in a previous post, however did not hear any transmissions. I also programmed the 10 channels used by Two Way Communications and heard what may have been paratransit service on TG 0-05-042. Having some time before I was scheduled to leave, I rode a couple of buses with the scanner programmed for all UHF frequencies licensed in Mesa County along with the Two Way Comm freqs. Although several conversations occurred while on the bus, they were not on the frequencies I had programmed. I noticed the buses were equipped with Motorola radios and had a channel "03" displayed. which may indicate a trunked system. Unfortunately, after I left town the thought occurred that perhaps GVT is using the State of Colorado system like Ft. Collins and Colorado Springs do. Can anyone residing near Grand Junction provide current information on my question?
