Wilson County (TN) VHF P25 Conventional upgrades are being prepared for the remaining WEMA and WCSO agencies. The Comm Tech Radio folks have been getting the infrastructure and repeaters ready in the recent months. With Wilson County procuring P25 capable radios over the recent years, some final flashing and reprogramming is what remains for the full switch.
The WEMA Bravo, Charlie and Delta repeaters will go P25, with WEMA Alpha remaining analog for fire dispatch alert tones for the time being. The Wilson Sheriff repeater channels 1, 2 and 3 also expected to go P25. This will put the majority of remaining public safety communications in Wilson County on P25.
The VHF Countywide repeater was the first to have been updated and submitted as running mixed mode with NAC 105.
Other WEMA and WCSO repeaters also mixed mode capability now and with some initial testing, look like remaining NACs will be:
WEMA
Alpha - will remain analog for now
Bravo - NAC 102
Charlie - NAC 103
Delta - NAC 104
Countywide - NAC 105
WCSO
Channel 1 - NAC 301
Channel 2 - NAC 302
Channel 3 - NAC 303
Will continue to submit updates to the RR DB as these details are confirmed and users go live with P25. There are also specific talk group IDs being used as well, even though this is P25 conventional.
The Wilson County VHF P25 repeater system is an upgrade of the existing six site conventional simulcast system, with repeater sites at:
Mt Defiance
Taylorsville Road
Boxwell
Franklin Road
Sheriff's Office / Jail
South Green Hill Road
Other VHF repeaters active, from South Green Hill Road at least, include Mount Juliet Fire (currently analog) and Police links (P25 digital / encrypted). There was mention of keeping and maintaining VHF repeaters and links up for Mount Juliet, and maybe using some City of Lebanon available VHF channels in the future.
WEMA Medics had also switched to 159.1200 MHz P25 NAC 180 (encrypted) for medical reports to TriStar Summit and Vanderbilt Wilson County earlier this year. This is not yet updated in the DB. Odd as the Wilson County EMA outdoor warning sirens continue to send data bursts on this same 159.1200 MHz frequency in analog mode with 110.9 PL, would think this would cause interference.
The existing WEMA and WCSO Digital East and West P25 channels, have seem some selectable encryption in the past. Right now have only seen evidence of P25 clear testing on the upgraded repeaters, would expect some encryption remains available.
