I was getting 2 bars max today in Kent, but 0% decode.

Heard Cleveland System testing this AM (8/22/12) between 10:15AM-10:30 AM while driving on Caves Rd in Western Geauga County. Participants were discussing further testing at hospitals and they are going to do an early morning test at Metro General on Thursday morning. The radios sounded like I was sitting right next to them on my PSR500. Loud, clear with great modulation. They were using TG ID #2

Heard Cleveland System testing this AM (8/22/12) between 10:15AM-10:30 AM while driving on Caves Rd in Western Geauga County. Participants were discussing further testing at hospitals and they are going to do an early morning test at Metro General on Thursday morning. The radios sounded like I was sitting right next to them on my PSR500. Loud, clear with great modulation. They were using TG ID #2

Earlier they were using two teams, one on TG1 and the other on TG2. Doing two hospitals at a time.

They broke for lunch at 10:30am and came back just after 11:00am.

TG1 at 11:13 was at Fairview, they had considerable coms issues.

TG2 at 11:10 was at Euclid hospital, again they had considerable issue's with coms.

Note: Having issues with coms at a hospital isn't unexpected. Large buildings, with sheilded rooms (Radiology, MR and Nuclear) plus large numbers of various electronic devices.

A short test was done at Metro (1:30pm to 1:50pm) on TG2. I was surprised by the poor performance. The testing was done around the ER, from the outside entrance up to the Heliport pad. The only clear coms came from outside of the building.

Two reasons why I was surprised by the poor results.

First there are two Cleveland P25 towers very close to Metro. A tower at West 3rd and the Schaaf road tower. Both towers have clear line of site and Metro sits right between the two. The Schaaf tower is roughly 2-3 miles as the crow flies, you can see Metro from ground while walking on Schaaf road.

Second reason I was surprised. I had monitored the early testing that the Cuyahoga MARCS P25 700Mhz had done at Metro. The test took place during the Phase 1 setups. Only the eastside towers were working, the closest was Warrensville 8-10 miles away. The techs were very happy with the results, commenting that it was considerably better than the results from the MARCS Moto II 800Mhz system. They were especially pleased by the results in ER and Radiology. The testing was done all through Metro facilities. To be fair there were some failures, like the underground tunnels. When the downtown Justice Center tower for the P25 700Mhz came on line they retested Metro. With additional improvements noted.

Summary: MARCS P25 700Mhz works at Metro from inside of the ER and Radiology departments. The first test for Cleveland P25, no luck from from inside ER or other departments (don't know if Radiology was tested, once the tech went inside of Metro mostly silence a little garble). Even thought it's an early first test, I am curious about the performance.

Different sites, different coverage, in addition to the fact that MARCS is using 700 MHz and Cleveland is using 800 MHz. With a frequency difference of around 100 MHz there will be differences in propagation.

Tom,

Thanks for the feedback. It's hard to believe that 100 MHz in signal would make that much of a difference.

By the way the "I was surprised by the poor performance" was meant soley for the Metro Hospital test only. For the Metro test I fully expected the Cleveland P25 system to out perform the MARCS P25.

I guess you'd have to be familiar with this part of Cleveland. Regarding just the Schaaf road tower. Two to three miles of unobstructed line of site (from the ground no less) from Schaaf to Metro's ER side of the building (where the testing was done). You should be able to do that with FRS radio's.

I guess we'll see how additional tests go. But the Metro test just stumps me.

This morinings testing on TG2 is at Cleveland Hopkins Airport and the RTA station.

 

[budevans]

Testing at Cleveland schools for the next two weeks. Where possible testing will take place after school hours.

cleveland ohio P25

do any body know that is the new cleveland ohio project 25 frequencies and new ID number

Could you restate your request. I don't know what information you are looking for.

 

[wa8pyr]

I believe this is what you're looking for: Cleveland Public Safety (Project 25) System Trunking System, Cleveland, Ohio - Scanner Frequencies

As there is already a Cleveland P25 thread (this one) I've moved your post to it from the Ohio MARCS P25 thread you originally posted in. Please remember to post your questions in the appropriate thread.

That doesn't seem to make sense, as testing should be done during school hours. Especially as you'd want testing to be as "real world" as possible. It's a stretch, but you'd want to see if there's anything they use in the school day that would cause system interference. Perhaps the radios used by security, buses, student and faculty mobile phone use, etc...again huge stretch, but senseless to wait until after school.

In the simplest of terms it comes down to getting access to all areas of the school and next minimizing the disruption of classes and school personel.

FYI: You just can't walk into a boiler room, electrical room someone has to show you around and unlock the doors. You don't want (men) techs wondering around womens locker rooms while they are in use. The list goes on.

I can appreciate those considerations.

They have to be escorted after hours to gain access anyways, so wear surveillance mics and ear pieces and do the testing when it matters most: during business hours.

i have a question is the cleveland p25 going to have a keep the old ID number or there going to have
a new ID number

The P25 system will have all new talkgroup IDs.

Has anyone heard any more testing on this system? The last audio I recorded was on 8/28/2012. It's been quiet as a mouse since then ( at least for me ). I'm using a HP-1E.

Thanks

 

[SCPD]

Logged them on the 29th, 30th, and 31st but not since then.

 

[TV88KEYS]

Thanks Ed..I was beginning to think there was something wrong on my end.

[budevans]

They're back to testing.

 

[TV88KEYS]

More testing today..

I'm assuming these are some of the numbers for EMS when they start up in November.
