Info on the Net indicates that Boylston FD has added some new gear based on a scheme typically seen in eastern Connecticut.
1. There is a fixed crossband repeater (FB2) in Boylston somewhere. Anything that it hears on 472.15 is rebroadcast on 33.06. And, anything that it hears on 33.06 is rebroadcast on 472.15 PL 110.9. (we dont know exactly how the PLs are set up on this repeater) 2. There is also 1 or more fire vehicles that have onboard repeaters (MO3 or maybe FB2T). These repeaters can rebroadcast from 475.15 to 33.06, and vice versa. (we dont know exactly how the PLs are set up on this MO3) 472.15 is considered to be the "dispatch" channel for UHF radio users. 475.15 is considered to be the "fireground" channel for UHF users. If I had to guess, I would guess that all of their portable radios are UHF, but they still have some vehicles without UHF mobiles. The vehicles without UHF mobiles might have just low band mobiles. Or maybe they still have a bunch of low band pagers. In any case, apparently they dont have the funds to move entirely to UHF at this time. Or they want the option to have a FG channel that is entirely separate from their dispatch channel. Or they want to keep some low band radios in use for extended range. Note - with 1 freq and 32 PLs - one could have 32 channels available. Once you start mixing and matching repeaters, PLs, and freqs, you can come up with a huge number of channel configurations. Heck - 1 channel with 32 PLs and 100 DPLs will make some people downright giddy (up). -- You received this message because you are subscribed to the Google Groups "massfire" group.
