The plan is for Baltimore City to change to the 764-870 MHZ on Dec 1st. Does anyone have the new Freq's or any info on this operation and what we need to do to upgrade? Many Thanks
Are they getting brand new radios or are they just reprogramming their current ones?That could be the case, but I'm not sure. 700 mhz range is alot lower than just 15 mhz. Also, I;ve been hearing companies and BC's going out of service for training on the "new radios".
The system you're looking at is the State of Maryland's new CMARC interoperability system (AKA waste of money) designed to supplement/replace the NPSPAC 8-TAC system. If you notice, the transmit locations are all Baltimore County tower sites. For whatever reason, the state has had each individual jurisdiction license the frequencies for the system.Is it possible that the city will begin simulcasting the two systems on Dec 1?
Doing an application search if found this INACTIVE application. It's filed under the city, but lists Balto County radio shop and POC.
ULS Application - Conventional Public Safety 700 MHz - 0004145238 - BALTIMORE, CITY OF
I'll program these into the PSR-500 and see what I hear.
Going back as far as 1-1-2008, I found no other applications that were in the 700 MHz band.
I don't know what will be done as far as station alerting. They DO have to replace the radios in the watchdesks since they are all Astro Spectras (3600bps only). I'm assuming there is some new protocol that will be used, with 9600bps, it may be thru the CC data stream, or maybe a stand-alone conventional channel.Matt,
You said the city is going to full 9600 P25. So the MOSCAD data is going away (or is there a new protocol that supports data)?
I also assume talkgroups will be renumbered (since they don't have to be base 16)?
Thanks for the new channel plan.
