Farmers Branch PD having a system 3 ?

[tonypl056]

Greeting fellow listeners,

I was monitoring my scanner yesterday ( 04/15/2013) and I heard one off. say to the other
off. " go to channel 3 on system 3 and then they were gone, up to then I did not know that FBPD had a system 3 let alone a system 2. I always monitor the main system and channels. there was supposed to be 3 additional sites added to the " Carrollton " system which Farmers Branch, Carrollton, Addison, and such operate on and I am still not sure if those are active yet. can someone please shed some light on this?

thanks so very much!

Tony.

some officers use codes between themselves to tell the other to go to his cell phone...don't know if this is what happened here or not.

 

[tonypl056]

thank you for that, most of the time here they just say call me on the beat phone. I know they have been reworking their radios and like I had mentioned there were supposed to be three (3) additional
sites added to the Carrollton system so it's very possible they are using the third site or system.
but as to date I have not seen any listings for id's or channels for those other two sites or systems.
hopefully someone has some info.

The system (Carrollton Public Safety Trunking System, Carrollton, Texas - Scanner Frequencies) has been running with 4 simulcast sites for several years now. There are not 4 separate systems where they switch their radio from one to the other, but are a single system with 4 sites that all use the same frequencies to help ensure full coverage. Their radios are programmed to allow some additional reliability and ease in interoperability though and this may be what was going on.

First (and most likely) was they switched to an interop channel. There are some options on exactly what this might be, however. They have some of the talkgroups from the "Systemwide Talkgroups" section programmed in to allow them to easily communicate with the Carrollton and Addison departments when they're doing a joint operation (or need to communicate with those agencies for some specialized tasks, such as borrowing one of their K9 officers for a search). They also have the standard NPSPAC interop frequencies programmed (generally called LAW1, etc.) to allow both interop traffic with other agencies (specifically those not on the same system) or communications when out of range of the system.

Second was they switched to another system for some reason. They have access to the Lewisville system, generally for communicating with Copell, and perhaps other nearby systems as well. I believe that they have backup talkgroups on the Lewisville system for them to use when the Carrollton system has failed (similar to Lewisville's backup talkgroups on the Carrollton system when the Lewisville system is out).

They also may have the ability to use a simplex channel to allow them to communicate car-to-car when out of range of the system. There are some listed at the top of the system's page, but I don't know if those are just for Carrollton's use or they allow access to the other agencies as well.

I've also seen the term "system" used interchangeably with "zone". In my city, when an officer responds into another division, the dispatcher will ask them to switch to [division] in [system #] so they can find the right channel. Our police radios have 36 zones in them here, so it's almost necessary to tell them where to find channels.

If it isn't a talkgroup on another system it might be one of these...
Farmers Branch is licensed for a conventional 800 MHz repeater on 854.9625.
WNDG564 (FARMERS BRANCH, CITY OF) FCC Callsign Details

It might be 815.55, 853.05 or 853.55 which are state interop channels.

If they have newer radio with 700 MHz capability it could be one of the 700 MHz interop channels or 700 MHz low power itinerant channels or 800 MHz interop channels.

Excellent info . and reads everyone! thank you all for your input, I guess even though I have been in the "radio" world for many years I am still learning and gathering information about radio's and systems. I really appreciate everyone's help. I hope that the info. and writes will keep coming.

Thank you all greatly !

The Metrocrest System consist of a 4 site simulcast system. All the agencies within metrocrest can communicate to each other on the System Wide channels for inter-local interoperability. There is a conventional channel in Farmers Branch but it isnt used. No radios within the system have any of the 700mhz interop channels programmed, they had the old NPSPAC channels but were removed when the 8-Call channels were added a few years ago. They use Lewisville as a back-up system and vise-versa. All the radios have access to all the cities and counties in the DFW area.

Hope this answers some questions..

FBPD radio system Cont.

Hi Folks, it's been a while since I have checked in here, I just wanted to follow up and give some input on the generous info. from the members here in regards to the FBPD radio system. I have been monitoring the 2 channels that FBPD has been licensed for( 854.9625 and 809.9625 apparently since 2005 and I guess they just renewed or applied for a new license in
May of this year. as I had mentioned I have been monitoring this frequencies (channels) for several months since my last post and sadly I have heard no radio traffic on either of these channels. I have not had a chance to listen to the "interstate" or interop channels that members suggested. I have found though, that while listening they have mentioned
that they will go to " in between" channels now I am old school and back in the day some of us, no names mentioned, had modified radios and could go "in between or use splinter
frequencies as it was known back then and have reliable communications without anyone but those of us who could do it hearing us. now I am wondering is this what FBPD is doing? it happens mostly when the CID folks get on the move and have a target and are ready to pounce. now I am ashamed to admit I still have the triple trunking radio shack
scanners and I have not yet upgraded to a " Home Patrol" unit the funds are just not available yet, please do not get me wrong I have no complaints about my radio equipment and several members have given my tons and tons of help with them. but could it be that my scanners are not " updated" enough to follow what I want to follow? or am I doing something wrong in my monitoring platform? I appreciate all the input you good folks give me so please feel free to suggest all info is greatly followed.

Thank you kindly, Stay safe and God bless

I believe they also have access to Dallas' TRS. Addison has backup groups here so I assume FB would also. Good luck finding them though. Dallas TRS is the busiest system I have ever seen.

FBPD Radio system

Hi Russell, Thank you for that. I wasn't sure about Dallas TRS. but you could be very right. i'll have to do some more research. thanks for the info.

You will never hear radios operating in simplex mode on the 806-823 MHz input band, as no commercial radio made is capable of receiving there. If you hear radio traffic there it is on a repeater or a trunk system. Add 45 MHz and you'll get the repeater/trunk channel output frequency.

A little birdie whispered in my ear that the Metrocrest member cities recently awarded a contract to Harris for a P25 Phase II system, but it should be operating on the same frequencies as the existing system and shouldn't be on the air until sometime next year.

FBPD doesnt have access to Dallas TRS. Only Addison uses Dallas for Backup. Everyone else uses Lewisville TRS for Backup

 

[Russell]

Well there ya go. I wasn't sure. It would make more sense for FB to use Dallas as backup rather than Lewisville due to their location. But logic does not always apply.
