I'm very unfamiliar with any of the current Metro Nashville scanner channels since I've been away from doing much scanner monitoring for 20+ years.
This was when I was living in Clarksville TN, and back then I don't think either city had switched to digital and/or trunking systems. I could even monitor some of the cell phone transmissions by merely clipping a diode in my old Radio Shack scanner.
I tried purchasing what was advertised as the HomePatrol Digital/Trunking Analog Scanner from C. Crane Company. This scanner was one that you could merely enter your ZIP code and then the scanner would set up most of your local scanner traffic. Sad to say, C. Crane no longer carries that scanner.
At any rate, it was good to hear from you. Since I'm somewhat disabled due to a stroke, I normally don't travel very far from the Nashville area any more. When I was employed by the phone company I did have the opportunity to drive I-40 thru much of W TN on my way to some vendor schools in TX, but since I retired from MaBell some 5 yrs ago, I've pretty much confined my ventures to the northern Middle TN area.
Maybe some day I get out in that area. If there's some way I can send a PM to you on this Forum, I'll do that so we can communicate more directly.
