Radios pass first test - 11/17/2004
Testing finds good results in county's new 800 MHz system
By ANDY ROGERS
Testing of Monroe County's new 800 MHz emergency radio system began this week and the project coordinator is reporting generally good results.
Some signals in areas of the county were poor - receiving a grade of 2 on a 5-point scale - but the $8 million system's overall performance during the early stages of testing has been acceptable, Sgt. David Thomspson, Monroe County Sheriff's Office, said.
"I think it's been doing well," he said. "A lot of the (areas) have very good quality voice communication."
The system was connected to the Michigan Public Safety Communications System (MPSCS) - a network of 800 MHz systems throughout the state - this month so testing could begin Tuesday.
"We affiliated with the state system last week in order to continue testing our system," Sgt. Thompson said. "You have to affiliate with the state system, so our three towers and the state system are all connected now and we can continue the testing that we have to do before final acceptance of the system."
The system is scheduled to go online Dec. 13, once several rounds of tests have been completed.
Coverage testing that is under way now will continue through the end of this week, Sgt. Thompson said.
"We will go to all these grids in the county to test the portable radios to see how they work," he said.
Two teams of radio operators have been assigned to test grids covering the county that measure 5/8 of a mile each. The radios are used to contact Monroe County Central Dispatch, where the signal is graded and a transmission is sent back to the portable radio team.
More than 200 grids were tested Tuesday. The entire county consists of more than 1,000 grids, Sgt. Thompson said. When testing is finished, the system must provide readable coverage capable of penetrating buildings in 95 percent of accessible grids.
The two testing teams have been divided into two sections, north and south. The crews began Tuesday in the western areas of the county and are working their way east, Sgt. Thompson said.
"It's scheduled for this whole week," he said. "We're hoping it will just take four days so it will be done by the end of the week."
Once coverage testing is complete, 800 MHz consoles will be installed in the dispatch center and tested. Several other system tests also must be performed before the Dec. 13 target date.
"It's continuous testing and seeing what the results are and if there is anything that has to be corrected, that will be done and it will be tested again," Sgt. Thompson said.
Motorola representatives, the MPSCS and members of the Monroe County project team, are conducting the coverage testing.
Sgt. Thompson said the digital radios should not interfere with landline or cellular telephones and no reports of interference have been received.

signal quality
scanner reception: monitored from the distance of 2 miles from the berlin tower---using 296d--note monitoring was done within 1 mile of nexhell tower--voice quality is very good--voice does drop out from time to time--set squelch volume to 60% + -this captured and maintained voice quality thru-out the xmission-but was too high for some analog stations and locked up on white noise---monitoring in a vehicle--same results--note: when traveling to washtenaw county i lost control channel just north of milan on us 23--

Well now with a CQPSK system within a short drive from Uniden (Indy) maybe we'll get something better from them in the future...
They aren't using the talkgroups at all yet? Still nothing ID'd in the database.

Re: signal quality
Believe it or not CCTV....I recieve the Dundee tower up here(ypsilanti area) very well, some nights better than others but it is at least monitorable. It truly is going to be nice when they finally do come on line completly

They are not listed in the database... Is something missing in your post because it doesn't make sense?

Rob, why do you think that everyone is "attacking you" That was no attack it was the truth. Look at all the Kal-zoo talkgroups, when those came out(with some very hard work) you had a problem with em, and all I was saying was you said that none of the talkgroups were out for Monroe, and I said even if they were you would not believe that they were truth(because you would not have been the one posting em!)
"They are not listed in the database... Is something missing in your post because it doesn't make sense?"
You probably should go back and read that one again!

I'm just a little dissalusioned with the quality of the installation by the vendor. The main purpose is to get the system up and running no matter what the cost is, whether it's a life and death, or loss of property.
To my brothers and sisters and in-laws in Newport, having the tower just in there backyard is good. However, NFD and other dept.s are probably still scratching their heads wondering where they'll get the money to pay for these new radios. Sure there are gov't grants, but what happens when someone gets too greedy and that money is depleted in a heartbeat? Time and time again, there will be "added costs, more money is needed for the system".
In techincal talk, I beleive the system works OK due to fact that Monroe county is mostly flat farming land. Take a look at the 800 systems througout the Thumb region. Thier 800 systems regardless whether it's APCO 25 or straight trunked works well in the farmlands. No obstructions. Line of sight with the tower. If the tower or system goes out, what is there to revert to, no fall back system?????????
Simplex 800 HT's to base is good for maybe a mile unobstructed? So it has been proven.
What happens when a medic unit takes it's HT into a hospital where there a leaded walls? Go ask the public saftey workers in the Western Wayne div. They can give all kinds of horror stories of calls missed becasue the radio honks-out as soon as they pass throguh the ER doors.
I am neither for or against this system, but hope for the best with the outcome. It's a long journey to having a good working system. But then again, no system works 100%.
Just my 2 cents.

i was referring to the monroe group control channel 868.4000 not the dundee tower---2 different control channels at this point in time..

Yes I know, I recieve both of the CC's here. I of coarse am on a beam pointed toward the AA Tower and so I only get about 1 S unit. It will still be some time before Monroe County starts using their own Talkgroups but it will be soon.

Any talkgroups ID'd yet or are they still just using the system / test groups?

So far they are still using the system/test talkgroups. However, I have to believe that will be changing in the next few weeks. According to one of the firefighters at Station 23, they received their new radios two weeks ago but they are still sitting in boxes, waiting to be installed.

The Dundee tower used to have some of the Detroit area MSP comms on it - is that still the case and/or is any of that resent on the other MoCo towers?
rdale said:
Yes, I am hearing the Detroit area MSP comms on it along with other state users. However, the Monroe County radios when they were range testing on the system, would not show up on the other nearby towers, even if they were closer to the Adrian, Ann Arbor, or Flat Rock sites.

Did they use a talkgroup?
