Yep. There's lots of corruption in the local governments there. Particularly in law enforcement. I'm sure that's a big reason they are choosing encryption.

Which is why they are doing it They are hiding there corruption.

Allegations of corruption in local government (especially unsubstantiated allegations), negative posts regarding encryption and implications of conspiracy are not permitted in RadioReference forums. Period.

If you have a beef with your local government, take it up with them. This is not the place for it.

It looks like Stow FD and PD have almost completely migrated off the old system. I've monitored all talkgroups and been decoding the control channel with only detected JOINs on the PD Reserve talkgroup.

Please monitor for addition Stow talkgroups. Remember, names could have changed from the old system.

Most of last week Stow PD officers were cycling in off the road to have radios reprogrammed. Have they migrated to the P25?

Sounds as if Hudson (2661), and Twinsburg (2121) also joined the system, as those talkgroups have been simulcasts of the legacy system.

Thanks for the info.

Remember that the presence of an agency on the P25 system just means a subset of radios have been programmed and are monitoring/using the P25 system.

Until the agency is exclusively heard on P25 (like Stow), the agency is assumed to be primary on the non-P25 system. It creates confusion from users of the radios that download from RRDB (HPs, Whistler, etc) when only partial traffic is heard, or they have a duplicate and don't know which one is the right one.

We should start seeing agencies drop off the non-P25 system pretty quick here.

In all fairness, Solon and Hudson still broadcast in analog, but we've updated them to their respective trunked systems. I get your point, but does it kill someone if the DB lands them on a new P25 talk group versus an 800?

 

[fpo701]

I see your point as well. There are a lot of occurrences of agencies using multiple systems. In the Summit P25 case, we know how things are set up.

We know that talkgroups pop up on the P25 system (and simulcast traffic from non-P25) when someone is listening to the P25 talkgroup. If the agency hasn't "moved" to P25, the traffic on the P25 is referencing the non-P25 system's names for the talkgroups.

Take Tallmadge for example. Before the cutover to P25, they used "go to command". That talkgroup on P25 is Fire 4. Had this talkgroup before the known migration to P25, it would have been added as "fire command".

Sure. I know what you are all thinking. That's why we can submit changes to RRDB and get them correct. On the flip side, the admins hear all the time that info in the DB is incorrect. Why? Because no one submitted the correction.

I am just trying to ensure that we get the P25 system's info as accurate as possible in the beginning.

 

[a388sig2]

That makes complete sense. So is the best place to share talkgroup findings right here in the forum until departments make the full time switch?

 

[fpo701]

Use the wiki page for the P25 system (http://wiki.radioreference.com/index.php/Summit_County_(P25)). We can create a section for future talkgroups.

Are not the Summit P-25 TalkGroups the same as the Summit 800 system with the TalkGroup number on the P25 the result of dividing the 800 system TG # by 16?

 

[fpo701]

The numbers are the per your formula. Some agencies have chosen to reassign their use. For example, Tallmadge has abandoned the use of named talkgroups (fire command, fireground x) in favor of sequential numbering.

Again, that's why simply migrating the talkgroups could be problematic. And the lack of consistent traffic on the P25 prior to full migration by an agency can lead to confusion about why a RRDB users can't always hear traffic.

Thanks Frank.

system freqs on 800 system new?

Did the voice channels on the 800 system get re-arranged recently?

My old documentation shows the 862mhz are new to me. The 858mhz channels I used to have documented are not in the sheet anymore. Something changed didn't it?

 

[fpo701]

I started adding some of agencies that seem to be consistent traffic on the system.

It has become increasingly difficult to determine when an agency has completely cut over. It is the reverse of the original challenge of random traffic. We now has cases where an agency has cut over, but one random radio exists still monitoring the old system.

I suppose the thing to watch for is consistent traffic. For example, there are submissions for Hudson out there. I haven't logged any traffic on the control channel for them today until a few minutes ago. That's likely an indication of only a few radios programmed.

Everything that has been added today seems to still be using old names. So far, Tallmadge is the only one to appear to have changed naming conventions. Please keep submitting corrections if you notice something is off.

Listeners should note, the talk group for Akron Fire “Command” is now an encrypted Talkgroup, as noted in the database.

I'm having same problem here in barberto. I have a home patrol with a diamSrh789 antenna and my reception sucks . I barelly catch anything and I'm in barberton .yet if I listen to Akron everything comes in clear.

You are experiencing Simulcast Distortion.

Do a search on "simulcast distortion" or "LSM" in the search window at the upper right and you will see why you are having trouble receiving the Summit P25 System.

Appears Richfield has migrated to the P25 system...
Richfield Fire Dispatch tg 2503
Richfield Police Dispatch tg 2489

I will submit to database .
