75.70 MHz
Years ago I purchased a Motorola Saber III radio at a hamfest. When I got home I found that the radio was an overseas radio and it operated in the 70 Megahertz band which is common overseas and not so common in the United States. What I did find was television video and audio (Channel 4 I believe) was within this band. The emergency call boxes along the Pennsylvania turnpike works on 75 MHz as well. I'm not sure if it's voice or data, narrow or wideband.

To ScanManQSL, the IMTS (Improved Mobile Telephone Service) was the predecessor to our current cell phones. They had limited range and didn't have the bells and whistles we currently have on our cell phones. I can remember listening to phone calls, for a very brief time, in the mid to late eighties. In fact, the first cell phone I owned was a converted G.E. IMTS phone. It was a real mobile phone that was "portable", if you could call it that, and was heavy.
I think the IMTS frequencies were reallocated to paging services a few years ago. It's been so long that I nearly forgot all about IMTS phones.

That would make since now. I’ve looked it up in the FCC webpage and YES, it stats that it is used for Caller ID, short messages, information update for phones, ECT. http://wireless.fcc.gov/services/paging/
Thanks for the info and I understand what I am listening to.
