If you are asking for the pl tone then Jamie, jfhtm350, has you covered. If you are asking for tone-out freqs, I looked and
I didn't see any tone-out freqs in the wiki for Blount County, maybe someone will have them for you.
I did find some for Knox County just in case you might like to have them. http://wiki.radioreference.com/index.php/Knox_County_(TN)
Wish I could help you more than this.
There is a program called 2tonedetect that will decode the tone-out freqs. You have to record them to your computer and let the program decode it. Ive havent got to try it out but I suppose it works good.
