In March 2000 RELM Corp. purchased the entire private radio product lines from Uniden America Corporation.

Bear in mind that Uniden of Japan is both a manufacturer of Uniden products and a contract manufacturer. Uniden private labels / labeled for Bearcat, Radio Shack / Realistic, Panasonic, Sony, and several other well known brands. Uniden (under its own name) dipped its toe into the USA land mobile pool, and decided to not go swimming.

You should read this page before any of the other articles here in the Uniden section.
Uniden Introductory Information   An introduction to the Uniden equipment, with background, history, some model-specific information,photos, and other miscellaneous items.

Most of the info below is here because at some time or another either the author of this page or a friend needed to locate this information, and we decied to post it here in case somone else needed it as well.

Consumer Electronics Equipment:

While looking for Land Mobile equipment manuals I stumbled across a consumer elctronics equipment owners manuals download web page. If you are looking for an owners manual on almost any current Uniden consumer product i.e. Cordless Phones, VoIP Phones, Business Phones, Marine Electronics, CB Radios, Scanners, Digital Cameras, GPS Navigation, Cellular Phones, Pagers, Radar Detectors, Satellite Receivers, Laptop and Palmsized Computers, Modems, etc. go to this Uniden page and select what you are looking for. Note that the "Two Way Radios" option is only bubble-packed consumer FRS radios, i.e. nothing in Land Mobile. And there is no older equipment listed.

Anyone have the owner's manual, service manual and software for the MR8100 scanner?

A note on the Uniden MR8100 Scanner: Introduced in 1989, this was one of the first scanners that had a serial port and matching computer software that could load the preprogrammed channels, in this case 10 banks of 10 channels. The advertised frequency range was 29-54, 118-174, 406-512, 806-956 MHz in AM and FM. This was not the "full" range, and the full range could be unlocked if you knew the secret key... In the Uniden software press <Alt>P and use the password 'ECPA1986'   (an interesting choice of a password).

Land Mobile Equipment:

The "Commercial Communications Division" of Uniden America was in Fort Worth, Texas. Repeater-Builder is looking for articles on the Uniden desktop repeaters (especially the ARH-351, ARU251 and ARU351), and other land mobile equipment such as the AMX-501, SMH-400G, SPU416K, etc. Also any programming software. Uniden Land Mobile Radio is pretty much long gone (the company focus is in other markets) so there's not much available to support any use of their equipment. The equipment is pretty much useless unless you have everything to place it in service... and I mean everything. So anything that is made available here will help the rest of us continue to use the Uniden equipment that is out there. And donations can be made anonymously.
