A good chunk of the CT Transit Talk Groups are also TDMA Phase 2.
Not sure if they will all go TDMA. Some people complain of TDMA losing voice quality. Police will be the first to complain if they did as clarity is very important for their communication. Also, with some sites having 12+ frequencies..which is overkill.... TDMA could double that-ish (Some are TDMA now so say 20 "slots"). Still overkill.
Here's a screenshot of Site I and Site A simulcast right now. One TG active LOL. I see two often... three on rare occasions... almost never 4 in use at once.
You might want to read up on channel loading, 12 channels on FDMA gives you 11 talk paths, Not close to enough when you understand how loading works.
During the day Troop I and Troop G systems do 8 or 9 conversations at the same time, last week I was in Waterbury and troop A had 8 going
Now add DOT (Coming soon) during a snow storm or large weather event along with everything else, or in the summer during a big thunder storm with the Encon PD, Parks and what not adding to it. The goal is not to have a busy that kills someone, so no 22 talk paths when it goes full TDMA wont be "Overkill" it will be "Safe"
