MBTA Radio Frequencies?

Postby mattl » Thu Feb 02, 2012 1:40 pm

Does anyone know the frequencies used by the MBTA for their radio communications? A friend is trying to figure it out, and currently believes it's around 800Mhz...
Oh, I bet you read a lot of Gordon Wood, huh? You read your Gordon Wood and you regurgitate it from a textbook, and you think you're awesome doing that and how 'bout them apples and all that Gordon Wood business?

Each line uses a different frequency. I've got them in my scanner at home. If someone else doesn't come up with them before I get home, I'll check and post them up for you.

As of this time only Bus Operations have been moved over to the new 800 MHz radio system, which I believe uses the EDACS system, so they cannot be heard. Here are the frequencies for the RT lines:

Red Line 470.4125
Orange Line 470.6125
Green Line 470.6375
Blue Line 470.6875

All using a PL Tone of 162.2.

Although I have noticed that the Orange Line cars are now being equipped with the newer radios so at some point they will not be heard.

These are from a list that I copied and pasted a while ago. Accuracy is not guaranteed. Frequencies may or may not still be in use.

North Side:
160.32000 - North Side (North Station, Newburyport Line, Rockport Line, Haverhill Line)
160.52000 - North Side (while on Pan Am dispatched territory such as the Fitchburg and Lowell Lines)
160.59000 - North Side (Fitchburg and Lowell Lines in MBTA Territory)
160.69500 - Engineering (Track, Builing, Bridge, and Signal Maintainance)
161.56500 - Engineering (Track, Builing, Bridge, and Signal Maintainance)
160.87500 - Boston Engine Terminal
161.16000 - Pan Am Dispatcher (while on Pan Am dispatched territory such as the Fitchburg and Lowell Lines)
161.46000 - Mechanic Help Desk

South Side:
160.68000 - CSX NA Dispatch (Worcester Line)
160.80000 - CSX Road Channel (Worcester Line)

Dispatchers and Trains both use the same frequency for these:
160.92000 - South Station, Northeast Corridor Lines
161.49000 - Old Colony Lines

These may or may not still be in use:

470.66250 - MBTA Police Channel 1 - PL Tone 131.8
483.56250 - MBTA Police Channel 2

The new 0700 Blue Line cars were delivered with a new radio that is not currently used.

The higher-end scanners costing several hundred dollars can program EDACS and other more sophisticated trunked systems including digital. It gets complicated though, not for the novice scanner user.

The digital system chosen by the T, when fully implemented on all the lines, will not be listenable by any scanner. So hopefully the analog will continue for a long time.

Does anyone have an online feed for the MBTA/MBCR radios? I can't seem to find anything.

Typesix, if you're willing to spend almost $500. you can buy a scanner that will program the most sophisticated digital trunking system. The only factor that I know of that would make it impossible to monitor is if they get an ENCRYPTED system, in which case you are correct. We're having that problem in my area now with our county police dept. having bought such a system. A buddy of mine has programmed it and can "see" activity on the system but because it's "encrypted" the scanner can't "decode" it. And yes, no scanner made today can decode an encrypted system. And I'm told it would be illegal for anyone to build a scanner with that capability. Not sure if it's true.

Ok the Mass State Police id trunked and I am able to listen to Troop F (Logan) anf Troop E (Mass Pike) and Troop A and H (Boston and South Boston) and it is labeled so I know what I am listening to . They if I am not mistaken they use a MOT-Type 2 Digital. Motorola equipment.

The system the T will be using is not encrypted, however the M/A Com system that will be used cannot be monitored by any consumer scanner. M/A Com will not allow Uniden or GRE/RadioShack(the two major scanner makes) to have a license or access to the tech specs in order to market scanners capable of scanning the T's system. You can find further info on the radioreference.com website on M/A Com systems.

Typesix, thanks for that info; it's a continuous learning process. Stevie, last I drove the Masspike almost a year ago, Troop E was still on the Turnpike's VHF freq's. Are they simulcasting the VHF and trunked or have they since discontinued the old VHF frequencies?

Does anyone know if all of the above still applies? I'm completely clueless as to how scanners work. I'm considering finally getting one. Would a scanner that can pick up MBTA frequencies also be capable of picking up fire, police, EMS, etc frequencies? I don't really know what I'm doing, but figure I'll check out some electronics stores soon for one.
