Police radio system fails

Icom, thats the thing. if it were put out to bid, then the specs would have to be met. there is no reason for extra equipment. company x guarentees x percent coverage and they have to provide it or they don't get paid its that simple. both the companies and the beancounters turn this into a game and quite frankly putting ones ass on the line with a flawed system is not something that should be a game. end of story.
In your opinion
I'd like your opinion on if this is the vendor's fault or not:
I was asked to sit in on a Motorola presentation for a proposed trunking system at a company I do other work for. (The work I do there has nothing to do with radios).
Their current system is three simplex VHF frequencies.
The chief complaint was that the company was hearing other companies on the frequencies they use, and that there were too many deadspots.
Since I can program Moto at another contract I have, I looked at one of their radios.
They were using CSQ. I suggested they put a PL on the transmit and recieve.
They had the vendor put a PL (I think it's now 627 DPL) on the radios. No more hearing other companies on the same frequency. They had been complaining to the vendor for quite a while, I heard people say at this meeting, about the interference from other licensees. The vendor is the one that programs the radios.
In your opinion, did the Motorola vendor have a responsibility to suggest a PL?
BTW: The people at this plant work mostly outside, So in the winter, they would put the radios on the belt clip or holster, and then put clothes and parkas over the antenna, pressing the antenna next to the body. The body is a great sponge for RF. I suggested they start using mikes with antennas on the mike. They did. No more dead spots.

Depends.
If the company approached Motorola and asked for a new system, Motorola did just that. If the company approached Motorola and said that they were having interference and Motorola told them that they need a brand new system, then I would be suspect.
Was it Motorola (with a bona-fide Motorolan sales representative) that did the presentation or a Motorola authorized retailer?

radio troubles
Having been a radio tech for Moto and a County S.O. . And now an officer in charge of my PD's radio system, I opted to keep my 800 analog Spectra-Tac radio system instead of going on the state trunk. Which does work well on Cape Cod. We added more recievers and a more powerful Quantar repeater. I trust my system to work when I need it. The major problem is that most agencys do not have people who are radio savvy. I have listened to some digital systems and they are difficult to understand. And you still can't recognize to whom you are talking to. But for the good news, Nextell will probably go under before the rebanding gets done.

I don't think that they (Nextel) think so! Anyone see the latest "Sprint/Nextel" commercial where there is a large group of firefighters in a large conference room and a Chief asking questions over a Nextel walkie talkie and the group of firefighters answering simultaneously over [their] Nextel walkie talkies!? Next, they will try to convince everyone that their walkie talkies work better than department systems!

Exactly!
Exactly, I have listened to the Philadelphia Police Radio System. Online only, because I do not have a digital scanner.
I have listened to two different feeds, so I know it's not just problems with one single feed.
I can understand the dispatchers and officers at times but other times, I am like "wtf did they just say?".
It's like they are mumbling or something.
I have never had a scanner system that I found hard to understand before Philly Police.
Also, why does there always seem to be a huge amount of background noise? I mean no so much people or other noises, but often it sounds like they are in a wind tunnel or next to a fan.

Why are you reviving a seven month old thread?
Why are you judging digital audio quality based on what you hear from scanners?
Geez.

Well....
Well, first of all, I knew it was a little old, but didn't realize it was 7 months old.
Also, I never really had any other way to judge it, because I never got to listen to a real digital radio.
