The line of heads is refered to as the "Odyssey" series. I have always made the assumption thats what the O stood for.
Ive seen criminals use p-25 scanners more than once in my career. One agency I worked for had a serial burglar using a cloned radio on a Motorola analog type II TRS listening to the burglary suppression unit while he was committing car burglaries.
These are the same gangs that are running mutli state counterfeit check rings, selling high quality fake ID's and SSN cards, bypassing burglar alarms, hot wiring European cars by cloning the RFID keys. There are a lot of very intelligent criminals out there. They too can read a manual on a trunk tracking scanner.
$600 is nothing, a 14 year old kid can make that in one day selling crack on the corner in Houston. A gang can easily send some girl in with a stolen credit card and buy a scanner.
Just last night I was listening to a live feed of an agency in the Dallas area here on RR. The live feed is scanning all their TAC talk groups and I could plainly hear them doing a moving surveillance of a bank robbery suspect all over town. I was listening on my iphone. Ive personally arrested people who were listening to us on their mobile phone using an app that links to a feed from this site.
I am a scanner enthusiast but I firmly support encryption on CID, Narcotics, SWAT, special ops, etc type talk groups. I say leave dispatch TG's in the open unless there is a very good reason not to specific to that agency.
From what I'm hearing, the Houston Phase II system is using encryption. Hopefully, they are bringing more sensitive users online first with encryption. Then they could leave patrol units in the clear, I don't know.
All HPD dispatch channels will remain unencrypted, as was mentioned in an earlier post in this thread. The only HPD channels that will likely be encrypted will be the TAC channels.
Thanks for clearing this up for me since I am reading about this from afar. I saw where TxWarn p25 added "T" to the mode column. I think this was in Houston. I suppose the trend will be TDMA for this one as well as the emerging system, the topic of this thread.
Let me just clarify something. The topic of this thread is a nonexistent TRS that was in place for a short amount of time and can still be found in the database here as a deprecated system. The city of Houston does have a Public Works TRS (X2-TDMA) that we have discussed here and which the Houston Fire Department tried out for a short period with poor results. The P2-TDMA system we have been discussing at length here is the TxWARN P25 system that has been in place for several years. The assets initially assigned and used on the deprecated system were transferred to the TxWARN P25 system and that is where the HPD and HFD will be moving. Understand that this is the same system being used regionally throughout SE and mid-east Texas.Thanks for clearing this up for me since I am reading about this from afar.

I asked the same thing if they had grounded it right, and if the tower had been properly insulated.
I was assured that they had taken every precaution they could, and that the lightning strike had more juice to it then the designers had anticipated in that one strike. Things like that happen right?
I mean, you can tell me that EVERY lightning strike is exactly the same as the one before it and after it?
That means that there isn't a deviation in electricity ever?
IS that what your saying?
I'll ask one of the systems engineers if I can have some pictures and if I can post them. IF he says yes- I'll have them up on tues, or wed.
I guess the coverage test project ended before he could talk to the "engineers"

Wait! Did I just get confirmation that the coverage testing phase is over?
I'm done here, because I had no idea what I was talking about.
vs...I'm done here, evidently trying to pass along along any information that I had was a waste of my time because you had Grem467.
Whereas those of us here in the Houston Metro area are appreciative of the the efforts and the information, really you don't need to attack someone else. This is really directed at both of you, the new guy (who apparently is leaving) and the old guy who should know better.There, I fixed it for you. Thank you for no longer contributing your mis-information to this thread.I'm done here, because I had no idea what I was talking about.
I asked - someone said they would email me, and then nothing happened.
Tommy,... Where else can an open designed P25 system be used ONLY with one brand of radio? ...
There are a few brands of agencies using non Motorola subscriber radios on the 1A7 network including EFJohnson and Relm. As long as the agency has elected to not use proprietary features, any P25 subscriber can be utilized. That's the beauty of P25.
