THE MOBILE TELEPHONE
IN BELL SYSTEM SERVICE, 1946-1993
These pages are a history of the car telephone as used by the Bell System and its affiliates from the beginnings in 1946 through the end of IMTS telephone product production, although many IMTS car telephone radio systems continued on the air through the late 1990's and some are still on the air in Canada and Pennsylvania.
The sections of this site are divided into chapters to make it easier to navigate and to help viewers still using dial-up and slow Internet providers. You can click on the appropriate chapter to go there directly, or just click on the "next chapter" link at the bottom of each page.

NOTE REGARDING MANUALS: Every month I receive at least several requests for manuals for the equipment listed here, usually from overseas persons. I am not a manual vendor, not a copying service and no longer have easy access to my manual library. This website is for historic reference and not a commercial venture. I am not retired and run a small business single-handedly. I simply don't have time to stand at a photocopier downtown to scan, clean up or photocopy and mail lengthy manuals, most of which have long fold-out schematics. Please understand that FedEx Office charges $ 1 per page to do these scans using their personnel. Therefore, unfortunately I usually will no longer respond to requests for manuals. Possible sources are QTH Classifieds on the web, or eBay.
