MaxTrac, Radius and GM300 series Information and Modifications There are Maxtrac, Maxtrac 50, Maxtrac 300, Radius, M10, M100 M120, M130, M208, M214, M216 and GM300 radios. While they look very similar, they are actually quite different internally. Then there are the DeskTrac stations, the DeskTrac repeaters, the GR300, GR400 and GR500 repeaters... This page presents an overview. |

Spectra Radios
Motorola has discontinued manufacture and depot service on this radio, and many police, fire and other agencies are replacing them. While Mike Blenderman K7IC has the definitive resource web site on the Spectra radios, we have a few goodies here. |

Saber Handheld Radios Motorola has discontinued manufacture and depot service on this radio, and many police, fire and other agencies are replacing them. Here's an overview. |

GTX 900 MHz Radios
Information about the Motorola 900 MHz GTX mobile and handheld ‑ probably the fastest and easiest way to get on 900 MHz. |
|
|
The MSF and PURC Stations
At the moment most of the information on this index page is UHF, but that totally depends on the information donations that we get... Repeater-builder would welcome additional articles on high-band and 900 MHz units. |
|
|
The MX Series
of radios The "MX Series" includes several crystal based (actually channel element based) and synthesized products that were first introduced in 1975. These radios including the MX320, MX330, MX340, MX350 and MX360 handhelds, the PX-300 and 500 packsets, the MTR-300 firetower repeater, the "APCOR" emergency medical repeater, and several others. |

An Overview of the
Motorola MaraTrac mobile radio
The MaraTrac is like a MaxTrac on steroids. Up to 99 channels, 100-110 watts, remote-mount. This article shows what's inside a UHF unit and a low band unit. The Radius M400 is similar. There are some MaraTrac scans further down in the manual section of this page. |

Info on the Genesis Series
of Handheld Radios by Mike Morris WA6ILQ This series includes the HT600, the HT600E, the MT1000, the MTX800, the MTX Classic and the MTX900. |
|

Anybody want to do a similar article on the Jedi series? (includes the GP900, GP1200, HT1000, HT1100, JT1000, MT2000, MT2100, MTS-LS, MTX838, MTX2000, MTX8000, MTX9000, MTS2000, MTS2010, MTS2013, PTX1200, and the PTX3600) We do not have a lot on the Jedi but we do have a Jedi model chart (but it does not cover all the models). We do have a Jedi Antenna Identification Chart, a four page spec sheet, and a 24-page specification sheet, chargers and accessories description sheet as well. |
|

Or the Waris series? (which includes the GP320, GP328, GP338, GP338-LS, GP329, GP339, GP340, GP360, GP380,
HT750, HT1250, HT1250LS, HT1550, HT1550XLS,

PRO7150, PRO7350, PRO7450, PRO7550, PRO7750,
and the PRO9150) Note that Moto marketing screwed up and has a MTX900 model in BOTH the Jedi and Waris lines. If you are buying a MTX900 make sure which one you are getting. They are VERY different. |

Making your own
TRN-4224A PL tone plug by Mike Morris WA6ILQ This device is used in mobile radio internal PL boards (i.e. Mitreks, Syntors, Maxar, Moxy, etc.), Systems-90 multi-PL mobile encoders and some other models. Since I first ran into the TRN4424 when modifying a Mitrek that had an HLN4181 tone board in it the article was oriented towards that radio and that PL board, however the article has been rewritten to include other equipment... the information is valid for any equipment that uses the TRN-4224 plug-in tone element. |
|
|
Making
your own TRN-6005A DPL code plug by Jerry Matthews WAØUZI A quad DPL board for a Micor base station is shown in the article, but the techinque is universal to any equipment that uses the TRN6005 including Mitreks, Syntors, Systems-90 multi-DPL mobile encoders, MSR2000 stations, and others. This article also includes a table of normal and inverted DPL codes. |

The UHF
R100 Repeater Service Manual This is the no-longer-available 6881078E15-O
manual. 25.4 MB PDF Donated by A. Nony Mous The R100 repeater was based on the German MCR100 unit, and that radios manual is also no longer available except here... 6881071E50-A (this PDF is also about 25.5 MB). It's also similar to the MC-Micro repeater which is / was available in a factory 220 MHz split. A note on the R100 ‑ it's built for either carrier squelch / PL or carrier squelch / DPL and can't be switched without replacing the main CPU chip, and that is no longer available as a spare part. I've heard horror stories from hams that bought surplus R100s that were configured for DPL and wanted to put them into amateur service with PL... If you have a DPL model that you want to use on PL just program the repeater as a carrier squelch duplex base station and use a TS32 or similar PL decoder, then run the COR and PL decode lines to a repeater controller that has both inputs, then combine them in that controller. |

Connecting the R100 to an external controller A tech writeup from Connect Systems Inc describing how to connect an R100 to their TP-154 panel. It's written well enough that the information is adequate to connect any other brand: ICS, Link, NHRC, Scom, etc. |

Moto
"Transistorized Dispatcher" radio 7.2 MB PDF Photo This is the
manual for the 1965 D33CMT series - a 15w pre-Motrac model. Note from WA6ILQ: I have good memories of the CMT - I used one of these as a base station on a couple of local 2m repeaters for several years in the mid to late 1970s / early 80s. Adding enable / disable switching to the PL encoder took a SPST switch and a piece of wire. Adding a second encode tone took a DPDT switch, a reed socket and a second reed. Later on it got more reeds. The CMT replaced a Link 1905ED mobile that had received power transformers in place of the receiver vibrator and transmitter dynamotor. I also hand ground the FT243 crystals for it. The CMT was later replaced with a 12-channel Motrola Metrum II (which got the reed switch, additional reed sockets and the reeds). |

Fabled Walkie-Talkie 1.6 MB PDF, by Leonard H. Anderson, 25 June 2005 More on what would be considered portable radios than handheld radios, bue still very interesting.
