I have monitored the Culpeper County radio system for several years even prior to the new Harris system. I use 4 different Astro Spectra radios, an Astro Spectra +, a CDM1250 and a Uniden Bearcat BC125AT none of them doing trunking tracking. All receivers are set for narrow band operation. I only monitor the VHF frequency 159.240 which I think is primarily used to activate emergency response member's pagers. The frequency deviation on the 159.24 is extremely low at times. I checked it on my IFR and it is in the .3KHz area At times the deviation is acceptable. The mobile units occasionally have acceptable volume. The mobile units often tell the dispatcher that they can not hear them. Sometimes the volume will increase after the dispatcher is told this. Also they have a high number of mobile transmitters remaining in the transmit position after a message is sent to the dispatcher. I recently added the Orange and Madison counties VHF frequency to all my monitor radios and was shocked by their clarity and volume levels. The prior Motorola system in Culpeper did not have these issues. Again I am not monitoring the 800MHz simulcast frequencies, only monitoring their 1 VHF frequency. Is this typical of a non Motorola system? What would cause these issues?
