Default Geauga County

Does anyone have any updated information on whether or not Geauga County will be switching over to digital and rebanding in January 2012? There have been some strange periods of 1 hour of no activity on my PSR 500 over the past several days and I wonder if they are testing for short periods on the new digital system.

They will be rebanding (mandatory), but as far as digital, unknown.

Looking at their frequencies they may have already rebanded.

851.21250 851.53750 852.21250a 853.53750a 854.21250 855.21250a 855.53750 856.03750a
856.08750 856.11250

After my post today the local newspaper came in the mail and in there is an article that Geauga made the first payment on a new digital system in December and implementation will begin in 2012 with a 12 month installation schedule. Since the Geauga County Sheriff's Department does the dispatching for numerous communities in Geauga my guess is they will be phasing in the conversion entity by entity. I know several of the communities have already purchased digital radios so I guess we just watch for the changovers.

Thanks for the responses.

Rebanding infrastructure retune is still scheduled for January, 852.2125 & 853.5375 have been removed from the control channel list and are now voice only.

We are planning on a 12 month schedule to install the new system, the new system includes 10 channels at 10 sites (100 GTR-8000 stations), seven MCC-7500 consoles, and a new logging recorder system.

The new system will use the same frequencies as the analog system and will still be a simulcast system. Encryption will be available, it's up to the individual agencies if they want to use it.

We'll be using the same core that the MARCS 700 MHz Cuyahoga County system and Lake County's future 7.x system will use. Roaming will be seamless between Cuyahoga, Lake & Geauga counties.

Thanks for the update Eric.

I am sure Geauga agencies need encryption to protect law enforcement agencies against all those Amish buggies that are scanner equipped!

What's Lake County's 7.x system? Will it totally replace their current 800 mhz system? When does Lake plan to implement 7.x? Will my Uniden Homepatrol-1 hear it if not encrypted?

7.x is Motorola's current P25 platform, the 7 is just a major version number, it has no relationship to the frequency band a system uses.

The most recent version is 7.11, due to fairly frequent software version changes a 'x' is often used to denote the minor version number when refering to these systems in general.

It will be new hardware on the same frequencies.

It should work however the new system will be a different system type & all the talkgroup ID's will change. You will have to manually program your Homepatrol or wait for the database to be updated with new system information.

Default Lake County P25 info

You can find some additional information in the Ohio MARCS - Cuyahoga Co Project thread at the top of the Ohio Forums page.

Open Ohio MARCS - Cuyahoga Co Project then go to Page 7 (page numbers listed right side of the screen).

Scroll down to Monitoring from Columbus message from me budevans posted on 09-09-2011, 06:57 PM. What I heard was the initial testing of the Mentor PD, P25 Lake County link to MARCS.

Click on following link to see the Lake County Simulcast info from the RR database.
Ohio MARCS - Multi-Agency Radio Communications P25 Trunking System, Various, Ohio - Scanner Frequencies

One last note: I haven't seen any additional posts regarding Lake County P25 testing.
