No...

KYWINS is/was the Commonwealth's wireless data system which allowed for communication/data exchange from mobile/vehicle applications to fixed-base terminals. From what I understand, the majority if not all of KSP's 800MHz Mobile Data terminals have been removed from their respective KEWS/private tower sites and the system was replaced in favor of FirstNet/Verizon vehicle applications.

I could also be completely wrong and It may still be operating... Not really a huge concern of mine
KSP cars all have Cradlepoint modems Cell Wifi LTE verizon

Analyzing the Control Channel on each site

So all of these sites are now online transmitting an active control channel? I'll have to call my cousin in West Paducah, and tell them it's time to buy a new scanner. His Uniden BC796D is due for an upgrade.

Just so you will learn something new to BRAGG ABOUT TACN is designed to use P25 Trunking FIRST and BACKUP is FIRSTNET LTE and I do not see that changing anytime soon.
This is starting to become common, especially with new and larger radio systems. Many agencies are adding LTE "fallback" to radios that have that capability, one agency that I know of has radios programmed with a few talk groups that are LTE only.

I've also seen a few radio system contracts that include connections to Motorola Critical Connect and WAVE as part of the system build.

I received several submissions overnight for this system. Some with slightly conflicting information and some not containing all the information needed to enter it into the database.

If possible in your submission please provide

I believe it. These statewide trunking systems are usually a multi-year project to plan, coordinate, construct, and buildout. The state of Michigan took 4-5 years to fully complete their system, and they are still adding new sites, and simulcast cells to the system every year, mostly to improve handheld radio coverage in rural areas. Conversely, smaller states like Connecticut, Delaware, and Rhode Island were completed in roughly a year, maybe two at the most. Considering the fact that Kentucky has some very mountainous terrain, the RF engineering studies have to take this into account, and initial tower locations will probably have to augmented by additional sites, which leads to cost overruns. This scenario has played out countless times across the country.

The cities and counties that are currently using P25 trunking systems that were built by Motorola, can be easily integrated into the statewide radio system. There will be costs associated with upgrading the microwave backhaul network, infrastructure, reprogramming of radios, consoles, common encryption keys, and other equipment. However, by integrating local systems into the statewide TRS, it allows for better sharing of resources, cost savings, and above all else a common interoperability platform that can help form a cohesive and coordinated response to incidents like what happened on December 10, 2021.

When it comes to the "Big E," there are numerous cases when some communities and counties use nonstandard encryption keys to keep other agencies from listening into their radio traffic. This really defeats the purpose of interoperability, when two neighboring towns, or counties are fully encrypted but can't communicate with each other on the same TRS. Then one dispatch center has to call the other on the landline so they coordinate resources with each agency, especially during a high-speed pursuit going from one area to another. This can be totally frustrating.

Just curious, can anyone verify the freqs for the Cadiz site? The database has 774.64375 listed which is the Control Channel for the Clinton site.

I got that as a control channel with a NAC of 9C8. Not a strong signal on the occasions that it is received. I'm assuming it's Trigg being that I'm too far away to receive Hickman.
