Can anyone tell me why Randolph Police has such poor reception? They should put them on the MIRS system.
Word at the shop is that Randolph will migrate to MIRS sometime around 1/1/11. Roxbury is scheduled sometime around 9/1/10. Randolph will keep their FD and DPW repeaters and possibly their EMS repeater on the air. FD and EMS as an "operations" repeater since they will be on the TRS response group.
But now for a bit of technical stuff. Randolph is licensed for something rediculousely small, like 37 watts ERP with a 7 degree antenna downtilt at (I forget the azimuth). The system has two sites. "Tactical" (repeater) has its transmitter at Town Hall, and three voting receivers (town hall, eastern end of rt-10 and western end of rt-10). This site was chosen to get into the shongum area and down by Ash Lane on Sussex Tpke. The main site is located near Sussex Tpke and Dover Chester Road. There are two antennas (one RX (approx 280') and one TX (approx 320')), going through a RX multicoupler and a TX antenna combiner, respectively. There are four transmitters at the main site, PD, FD, EMS and DPW. Each repeater has three voting receivers (Main site, eastern end of rt-10 and eastern end of sussex tpke). All hardware is identical and the tie lines are/were pretty reliable. There was a problem in the past of the Power Amplifiers burning up and the related channel would obviously have next to no power output.
That could possibly be the problem on the PD channel right now, but I do not service them to be able to tell you for sure.
Sorry if there are typos or other things that don't make sense, I typed this from my bb.
