I thought the original plan was to move to narrow band then P25 conventional using the same channels. I know they have TGs on LWIN but I am not sure if they were using them. I don't get back to Louisiana nearly as much as I used to.
APD is dispatched by TPSO. TP was originally going to go P-25 Conventional, then they had some issues come up, then figured cheaper and easier to go LWIN than completely rebuild thier own system.
I'm monitoring T.P.S.O. now on LWIN - they also dispatch Tickfaw Police, too. I like it better now than when they were on VHF...clearer signals. Thanks!
Hammond PD moved to LWIN months ago. They still also use the encrypted VHF repeater too but most all traffic is on LWIN in the clear last time I checked.
