Ok, been away from here for a bit, but I have somewhat of an update.
Loudon County SO has several TG they utilize, unfortunately all are encrypted so I can't determine which is which. I do now know that they have a ADMIN, CID, NARCOTICS, MUTUAL AID, and a couple of other TG, but I have no IDs for them right now. I know that 7504 is LCSO, but I can't figure out the ID, due to the encryption. I can only guess it is the ADMIN channel, but not confirmed. I also found out that the Narcotics channel is double encrypted, so even the regular deputies cannot hear what is going on on that channel.
LCSO has now fully encrypted all traffic on their dispatch channel. Every now and then a deputy is in the clear, but 99.9% of the time it is encrypted.
Also, Lenoir City Police and Lenoir City Fire are expected to switch over to the TVRTS by the end of the month. I'll keep monitoring and update when I get more information.
For what it's worth, I have been picking up Catoosa County, GA medical and SO traffic on their talkgroups on the Lenoir City, Oral and Madisonville frequencies. More than 100 miles away from me. Interesting.
Also found out that the tower site listed as "Lenoir City" in the database is called "Centerville" and is programmed into the radios with that ID. That makes sense since the site is actually in the "Centerville" community between Lenoir City and Greenback. Also heard LCSO deputies talking about another tower, possibly in the Loudon area. Don't have any other info on that, but I'm wondering if it might be the Madisonville tower site off Hiwassee Road. If anyone knows anything about a new tower, let me know.
And I do know there are several dead spots throughout Loudon County, especially in the Philadelphia area. They still have to use the 460 radios to get out in those areas.
That's what I got for now, and will update when I learn more.
