Tri-Met Talkgroups-Road Supervisors

[k-9policexj]

Ok, so after seeing and dealing with the traffic mess caused by snow this past week I thought it would be good to monitor Tri-Met. My question is what talk group does/do the bus road supervisors use? I found two listings in the database for road operations (28496, 27856) and one for bus dispatch (28432) but not getting any audio, at least when I've been listening. When I search with the radio most of what I hear is Light Rail, which isn't really what I had in mind.

Thanks in advance.

The Supervisor's talkgroup (28432) is extremely busy - if you're not hearing comms, double check the programming for the system to ensure you've got your particular scanner configured correctly.

Additionally, during winter storm events, traffic is split according to need, so you'd need to check any talkgroup which isn't specifically assigned to Light Rail.

The comms to the buses themselves are on the legacy 450MHz system, which is also listed in the database. This system operates in a "pseudo-trunked" mode of operation, and utilizes 3 450MHz voice frequencies. (There is a 4th 450MHz voice frequency that is an overflow frequency and is shared between fixed-route and paratransit buses.)

Thanks for the info guys. I double checked the talkgorups and it seems that I entered the talkgroup wrong...I will try to monitor and see what I hear
