If they did encrypt I suspect it was due to a suspicion they had about the bad guys monitoring a police chase? In any event, the possibility once encryption was turned on, they may have forgotten to turn it off? I don’t know what their policy is for the traffic channels, or if the policy has changed, but if it is normally intended to be un-encrypted, let’s hope they realize it and resume normal.

AS I recall Traffic channels for CTSP were used for speed traps and the truck (commercial motor vehicle enforcement) teams.
Sounds about right… just spitballing here but maybe someone ran a speed trap and they suspected the guy had a scanner. I know it doesn’t make much sense, if the guy had a scanner he should have been for-warned about a trap and slowed down. I haven’t followed the CSP’s system much so I can’t help if they did anything like changing what TG’s are assigned to what.

When they run radar, there is no conversation about it. It's a one person operation.
In the old days, you'd hear them calling out the offender over the air but now all you'll likely hear is "All set MDT".

Do they no longer have "speed traps" where one officer does the clocking and radio call and the second is parked further up to conduct the traffic stop? I know they did when I was a kid.

Nope. No more.
I once stopped at a cop running radar and he let me sit in the front seat and witness the radar. Pretty cool! I also stopped to talk to a cop when LPRs 1st came out. Very powerful tool!
I didn't monitor the Traffic channels often. Just curious, what were they normally used for? I know i heard soem radio tests on them once.
Last major incident I listened to, if say Troop H had a chase or similar incident, that would stay on the Dispatch TG, to avoid unnecessary channel changes while chasing, calling out locations, etc. and any units not involved would switch to the C/C TG and that would become dispatch for everyone else until the first incident wrapped up or at least calmed down enough for other comms.
What you are saying more accurately is there still is a conversation, but it’s been moved to the mobile data terminals (MDT’s). While its good to know, it was just one possible example, a reason for encrypting. I’m sure there are others. As stated, I was just spitballing.
So far, no one has posted a known reason for the traffic channels going encrypted. This tells me it’s not the reason we should concern ourselves with so much as the fact. They really don’t need a reason. They could give us any excuse or none at all, as long as it’s legal. Or simply feed us apologies every time they encrypt and forget to reset! It’s pretty much “You get what we give you, like it or not!”
Ive not seen a CSP car on the interstate highway while I was traveling themf in many years and their dispatches haven’t fore-warned me about possible slowdowns or detours (the primary reason I started listening to CSP). So as far as I’m concerned, it’s getting close to a waste of time to monitor CSP (AAA with a gun), not to mention their trunked system can put a big dent in your scan rate depending on how many sites and TG’s are programmed. I still have them active in my SDS200 but limit to Troop H & L dispatch.
Traffic is often used for escort duties, that may have something to do with those channels moving to Encrypted.

I know on Sunday the 20th there was a joint exercise involving CSP, CSP traffic Services, TSA, CT SP DMV units, DHS WMD teams and others that go bu COBRA (Collaborative Operations By Response Agengies doing a "highway strategic deployment" on I-95 in Greenwich, possibly they used those channels during that exercise and failed to drop encryption after the fact.

Thank you for that.. I appreciate it. So, lets say I want to listen to Eastern CT Hotline. I would put the frequencies of my closest tower in, filter out the control channel and then input the DEC and HEX and be all set?

Phase 2 Simulcast system, you will need a P2 capable scanner/pager ...

Will it also work with conventional P25? Or just Phase 2?
It certainly doesn’t require you to “Key up” as you say. That would infer the ability to transmit. I am assuming you are listening on a scanner? Common scanners are a receive only device.

Once again... What type of radio?
IF your radio is capable, you need to enter the Control Channels and the Trunk Groups you want to monitor
Then you can eliminate what you don't want to receive.
What is your location?

I have an SDS200 but I am thinking about getting a NX-5800.

it is a phase 2 system, pretty sure all TGs are p2 now
