They were both dial and Touch Tone.<br>There was a roaming mode.<br>Oh....IMTS stands for Improved Mobile Telephone Service<br><br>We grew up in San Antonio, TX and In 1971 my dad had one in his USAF car. He was in the Air Force. San Antoinio (as I recall had 2-3 VHF channels for San Antonio and there were other channels for other cities. With a maximun of 8-10 channels. There was a series of switches at the top of the control head you selected your channel.<br>Also, It was very easy to listen to other phone calls and the range was quite good. You could go 30-45 miles out of San Antonio and it would still work good.Mark A. Lacynoreply@blogger.com
