By any measure, the buzz has been extraordinary and the collective marketing outlay by Gap, Apple and Motorola has been enormous, with some estimates as high as $100 million. Gap alone spent $7.8 million of its $58 million outlay on Red during last year's fourth quarter, according to Nielsen Media Research's Nielsen Adviews.

Note: Any Motorola prices mentioned on this page (or on any page at this web site) should be taken only as a rough guideline. Motorola adjusts prices quarterly, and offers one set of prices to their dealers/service shops (the so called 'NSO' or 'National Service Organization' pricing), another to 'self-maintaining' fleet customers (i.e. those that have their own radio shops: cities, counties, police departments, fire departments, etc), and a third on their telephone order desk (i.e. retail sales). For these reasons readers should use the prices mentioned in an article only as a rough indication.

The list of manuals below is from the official Motorola list. Prices listed are August 2007 unless otherwise noted. NLA indicates that they were No Longer Available at that time. Click here for instructions on how to order manuals and parts.
Note the trailing chassis version letter on your radio. The 'A' version chassis are unique and have their own set of manuals.

• The 800MHz Mitrek is pretty useless in the amateur world. It uses a single oscillator/multiplier chain for both receive and transmit, and the IF is equal to the repeater offset, something like the old 'Pulsar' series of VHF or UHF mobile telephones. You could hack and slash at it and make it receive at 900 MHz (it will never transmit at 900 MHz), but there are easier and much smaller radios that work just as well if not better to start with (an 800 MHz MaxTrac comes to mind, and a conversion article is on this web site). In short, the 800 MHz Mitrek radios make pretty good doorstops.
• If you are going to do a mobile install of a Mitrek, and if you can find the official Mitrek Installation manual (6881110E50) at zero or very low cost, then it's worth spending five minutes and looking it over.
• The standard control heads and cables are covered in the regular mobile manual. Motorola also offered the 'Systems 90' control groups for the MICOR, Mitrek and Syntor line for mobile installations that needed multiple radios, PA, Siren, scanning, MPL (operator-controlled Multiple PL encoder tones), etc. The 'Systems 90' control set boards and housings were originally used on MICORs, later on Mitreks, and were retrofitted to Motracs, Motrans, Mocom-70s, and a few other radios. The 'Systems 90' control groups are covered in their own manuals. There are several posted on the MICOR page of this website.
  • Siren / PA.. 6881108E05 ($11.26)
  • Alternate Control Module.. a 4-channel control head on a card.. 6881109E56 ($7.52)
  • Channel Scan.. 6881102E23 NLA
  • Channel Scan.. 6881109E58 NLA
  • Voice Privacy Adapter.. 6885900C35-F NLA
  • Multi-PL encoder.. (don't have it yet)
  • Wildcard.. 6881102E35 NLA (just a board with momentary and latching switches, extremely configurable by the installer.. light bar, alley lights, siren, dome light kill, stop light kill, etc).
  • The complete module wiring diagram showing how all the units cable together is 6881109E49.
  If anyone has PDFs of any of the System 90 documentation we'd appreciate a copy so we can offer them for download.

A note on mobile installs: Mitreks make great install-them-and-forget-them radios. Several friends have 4-channel Mitreks stashed in the trunk or under the back seat in their cars, and set up on a couple of local repeaters. A couple of the UHF ones are configured for full duplex, with two antennas, and until you have actually USED a full duplex mobile you don't know what you are missing, especially on an autopatch or a remote base. And the receive antenna can be shared with something else.

That said, a lot of Mitreks were installed in the cabs of 18-wheel tractor-trailers. Because the truck manufacturers (Mack, Kenworth, Peterbilt, etc.) had not standardized the polarity of their tractors when the Mitrek was introduced, it was common for Mitrek cables to be modified in the field from negative to positive ground when a positive ground truck was encountered. As a result, you will find some cables on the surplus market labeled for negative ground but rewired for positive gound, in other words the part numbers stamped or printed on cable assemblies may not correctly reflect the polarity for which they are wired. On a new-to-you cable kit it is best to open the connector shell and compare the cable wiring to the negative ground and positive ground cable diagrams in the service manual before you power up the radio on the bench, or before installation - look at the diagrams and compare them, then take 30 seconds with an ohmmeter and check (thanks to KI4BQQ for the reminder).

The 'Mitrek Plus' radios were originally special purpose / modified Mitreks and are described in the Mitrek Plus Supplement, part number 6881046E05. 626 kB. I was told that the 'Plus' changes were later rolled into the 'B' or 'C' version chassis - but I haven't taken the time to verify that - it would take comparing an 'A' version manual to the Supplement and to a 'B' or 'C' version manual to verify that.

The Mitrek Plus supplement also notes that the Mitrek is an all-metric radio. Don't go casually throwing any extra screws into your non-metric screws bin.

The Motrek was the single-channel or two-channel economy version of the Mitrek. It was a couple of hundred dollars cheaper than a Mitrek (which had one to four channels), so there were a lot of sales in basic radio systems such as in taxicabs and delivery trucks.

The manual for the T43/53/73 VHF radios is 6880100W30, the T34/44/64 UHF radios is manual 6880100W35. As of early 2012 the VHF manual is still available; the UHF manual is NLA.

Information common to the Mitrek and the MSR2000

Mitrek Mobile Radios

First, let's figure out what chassis you have:

RF related Information:

The official Mitrek and MSR2000 tuning tool is part number 6684230K01. GET ONE (preferrably two). The misery caused by a cracked slug is not worth the few dollars it costs. If you are new to the Mitrek or MSR I'd get two, and leave the second in its little envelope in the tool box. Then when you break #1, you unwrap #2 and put the wrapper in your pocket. That night, at home, when you empty your pockets you will find the wrapper and that will remind you to order #3. (Note - some MSR manuals list two tuning tools, 6683398A01 and 6682977K01, but both are NLA from Motorola).
You will want to add a flap of tape to the tool - for two reasons - one to keep it from rolling off the bench, and a second to count turns as you twist a tuning slug.
UPDATE (June 2011) The original tool(s) are now NLA, so the current tool of choice is the MICOR Universal Tuning Tool 6684387C01, which is still available, for about $6 each. This tool has a thin steel blade on one end, and both 0.075' and 0.100' hexes on the other end. In addition to being the tool of choice for most Motorola equipment, it also is suitable for tuning General Electric radios such as MASTR II, Exec II, and MVP.
What sets the MICOR tuning tool apart from many other commercial tuningtools is that it has a large-diameter finger grip that allows the user tomake sensitive adjustments very easily.
