New SLERS P25 aircraft system possibly found.

Last Friday, I stumbled upon a new P25 control channel which sounded like the Harris variant on W2SJW Radio Sounds website. I read some time ago that they were going to convert the SLERS aircraft only sites from EDACS to P25 (unfortunately it most likely will still be all encrypted).

Here is the output for two tower sites picked up from PRO96COM

I received this in Jax a couple of weeks back.197 is listed as Rhode Island State System.They don't have any 700 Mhz listed so I was wondering about it.

I am now pretty sure this is the new SLERS aircraft overlay system because every talkgroup that has come up has been encrypted and the old EDACS aircraft sites have been turned off at least in Orlando.

I think eventually this system will also replace EDACS system over time.

All of the SLERS aircraft sites statewide have been 'upgraded' to P25 as of a month ago.
And yes, over time P25 will take over EDACS....but over time is the key there.............
