Mike,
Using Pro-96 monitoring software on the Berkeley and Jefferson County sites since December 10, 2021 I've found the following:
1) I've not logged an encrypted transmission on TG1107. It only carries announcements from dispatcher, no radio traffic between County units and dispatcher. There were a few occasions where I recorded state police units communicating to the Berkeley dispatchers, but that seems to have tapered off since the Holidays have passed.
2) ALL communications on TG1141 are encrypted. No logs indicate since 12/10/2021 that an in-the-clear transmission has occurred.
3) County Law enforcement traffic is also occurring on TG1106 and TG1108 which appears 100% encrypted all of the time. Their use is unknown so far.
4) I cannot confirm TG's 1117, 1143, 1141 are full-time encryption. It appears so at this time, but I have no concrete logs to prove it. There's just not enough traffic on them.
5) Martinsburg PD traffic is not encrypted so far. TG1109.
6) All Berkeley County Fire Private Company channels are encrypted all of the time for several months now.
