I'm not sure it has been made clear here, but the NMSP does not use repeaters, they use remote base stations. A repeater re-transmits the mobile or input frequency. A remote base is a just like the base station in an office, except a base station radio has been placed in a building on top of a mountain somewhere. In flatter areas of the country, such as the midwest the remote bases are located at the base of towers that have antenna hundreds, or even thousands of feet, above these bases. The remote base is connected with an office or dispatch center using radio link frequencies, UHF in a lot of cases, phone lines or microwave. The State of New Mexico uses remote bases for the State Police, New Mexico Division of Forestry and New Mexico Game and Fish. In the case of State Forestry the mobile calls in the the same frequency the base station does. This is simplex, just like car to car. In the case of Game and Fish the remote base stations transmit on 44.80 MHz and the mobile units receive on this frequency also. However, the mobiles transmit to the base stations on 44.920. In most locations, when not on a high peak, you will just hear the base station, not entirely because the base station might be more powerful, but because it is located above the average terrain.Does anyone know the frequencies for NMSP-Las Cruses area? The receive and transmit frequencies? And PL Tone. I can hear the SP Dispatcher, but can't hear the Officer.
