Radio Doctor For Motorola Radius Gm300 Programming Software
The first two things I ran across was the “Radius GM300 Radio Doctor” over at and the original Motorola Radio Service Software (RSS). The GM300 Radio Doctor piece of software did a good job at being able to program this ancient radio with a “modern” OS like Windows XP. After searching for the genuine Motorola program I came across Motorola Radius GM300 Radio Doctor. This program runs fine under Windows XP and will do all the functions that the genuine Motorola radio service software does. Here is the main screen. See a video of the software in use.

Attention Ebay buyers and sellers: If you are buying or selling a MaxTrac, Radius mobile, or GM300 you need to read the warning on this page.
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' Pricing ('National Service Organization')), 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 to the public). Prices are changed quarterly, so use the mentioned prices only as a rough indication. If you encounter a large price change on anything where we've mentioned a price we'd appreciate an emailed update.
Radio Modification and Descriptive Articles:
Caution: A lot of the information in the articles below is valid only for MaxTracs and MaxTrac-based Radius radios (the Radius mobiles that have the letters LRA in the middle of the model number). The MaxTracs came first, then when Motorola needed radios to sell as Radius models (i.e. retail sales products) they changed the label and the firmware. There are some very slight differences, but there is a lot of commonality between the hardware (the circuit boards, etc) inside the MaxTrac and Radius LRA series mobiles.
Motorola Radius Gm300 User Manual
The later GM300 series (which includes the Radius M10, M120 and M130 radios) look a lot like the MaxTrac and Radius LRA series, have similar specifications and physical construction, but are actually quite different internally. The GM300 series do not respond well to being blanked by the MaxTrac Lab RSS. There is no Radius or GM300 series Lab RSS floating around (yet) so unsuspecting experimenters can turn one of these radios into an expensive brick if not careful. See the GM300 article below for more details.
Astron makes a power supply for the MaxTrac / Radius LRA / GM300 series that has a sleeve on the top that the radio slides into. The SL-11-RRA supplies 13.8V at 11 amps. Click here for a photo.
Note that the MaxTrac / Radius / GM300 radios have a 10% transmit duty cycle and that translates to 10 seconds of transmit and 90 seconds of receive, or 30 seconds of transmit and 4.5 minutes of receive. This is definitely not repeater service or any kind of amateur radio service that I'm familiar with! And besides, the rear mounted heat sink does not cool the pin diodes or any other PC-board mounted components. Reducing the transmit power can help, but some models have a minimum rated power level (like not less than 25 watts and not more than 45 watts). In other words, the MaxTrac, Radius and GM300 are nowhere near the conservatively rated and over-heat-sinked designs of the MICOR, Syntor or Mitrek era radios.

Interfacing Articles:
| Repeater controller interfacing - with photos By Scott Lichtsinn KBØNLY With information on connections to radios with both 16-pin and 5-pin logic boards. |
| Simple Repeater Interfacing forMaxTrac / Radius / GM300 Radios By Robert Meister WA1MIK A very simple procedure with all the details needed to interface these radios to most repeater controllers. This is a companion article to the ones above and below. |
| Repeater Interface for two radios 207 kB PDF Using a ID-O-Matic II kit, by Dale NØXAS, that has both a CW ID and a Time-Out/hang timer to make a repeater using MaxTrac, Radius, GM300, or CDM-series mobile radios. |
| Using a MaxTrac / Radius / GM300 Mobile Radio as a CW Beacon Transmitter By Robert Meister WA1MIK The HamGadgets ID-O-Matic had all the features necessary for this task. It was just a matter of finding a way to transmit real on/off CW rather than modulated audio CW for beacon use. Should also work with the MaraTrac radios. |
| Using Remote Channel Select on a 16-channel GM300 radio By Robert Meister WA1MIK A transcription of a PDF file with additional information that explains the wiring and radio configuration you need to remotely select channels on the 16-channel GM300 radio. This won't work on the 8-channel GM300 because the firmware won't allow you to reprogram the accessory connector pins for this purpose. |
Modification and Repair Articles:
| Diagnosing, Troubleshooting, and Repairing MaxTrac Radios By Robert Meister WA1MIK Hints and helpful suggestions for repairing MaxTrac, Radius, and GM300 mobile radios. |
| Disassembling the GM300 Mobile Radios By Robert Meister WA1MIK If your GM300 is way off frequency, this is usually caused by dirty interconnect pins between the logic board and the RF board. You'll need to take it completely apart to clean them. Here's a procedure for doing it. |
| Narrow-band conversion kits for the GM300-series radios By Robert Meister WA1MIK Transcribed from the official document that can be found elsewhere on this site. |
| Adding additional channels to the GM300 By Thomas M. Mayse, KN5S If your GM300 has the expanded logic board it can have as many as 40 channels. Moto learned their lesson on the 32-channel MaxTrac and artificially limited GM300 to 16 channels so that they could force anyone needing more than 16 into a Spectra. Tom walks you through the process with a step-by-step procedure. |
| Upgrading a MaxTrac or Radius M100 / M214 / M216 to 32 channels - with photos By Scott Lichtsinn KBØNLY A step-by-step procedure that will upgrade any MaxTrac (except the 2-channel ones) to 16 or 32 channels (depending on which logic board you have), with options like scan. |

| Moving a 449-470 MHz MaxTrac to cover the 440-450 MHz Amateur band - with photos By Scott Lichtsinn KBØNLY A step-by-step procedure that makes a UHF MaxTrac a lot more useful on 440-450 MHz. |
| Manual Power Control of the MaxTrac PA deck By Robert Meister WA1MIK When a MaxTrac (on any band) is run out of it's designed frequency range the power control routines in the firmware get confused. Unfortunately the confusion causes the radio to run the PA deck wide open, which can burn it up. This writeup gives a workaround. |
| Volume Control Replacement By Robert Meister WA1MIK If you have a MaxTrac, Radius LRA or GM300 series radio that runs at full volume all the time, or either turning the volume control has no effect or causes a huge jump in volume, then you have a broken volume control (a common problem). It's a simple, inexpensive fix and this writeup walks you through the repair. |
| Volume Control Replacement UPDATE By Robert Meister WA1MIK The original and new Motorola pots are No Longer Available but an alternate part can be purchased for about the same price that does the job quite well. |
| A Squelch Mod for the MaxTrac / GM300 / M120 By Barry Sloan VE6SBS Barry's web siteOriginal offsite article This simple mod minimizes the squelch tail duration - a useful feature on consistently strong signals (such as on point-to-point links). And if you want, you can add a switch to make the modification selectable at will. Just add a toggle switch in series with the lead of the capacitor. |
| Converting an 800 MHz talkaround MaxTrac to a 902 MHz Repeater Receiver By Robert Meister WA1MIK An 800 MHz MaxTrac mobile with the talk-around option makes a good 902 MHz link, control or repeater receiver. This writeup walks you through the process. |
| Converting Other 800 MHz MaxTracs to the 900 MHz Ham Band By Robert Meister WA1MIK A continuation of the above article based on followup information. |

| Extending the MaxTrac 900 MHz VCO Frequency Range By Robert Meister WA1MIK andDavid Malicki, N1OFJ How to move the 900 MHz MaxTrac VCO down to 902 MHz. |
| Getting the MaxTrac 900 MHz radio to fully cover 902-928 MHz By Robert Meister WA1MIK An expansion of the articles above and below, with detailed analysis. Also shows a way of adding a manual deviation control if your radio needs it. |
| Changing the MaxTrac 900 MHz VCO switch point By Robert Meister WA1MIK The MaxTrac 900 MHz radio's VCO has two ranges. This article explains why, and shows how to change the frequency where the range is switched. This will extend the useful operating range of the transmitter. |
| Converting a 900 MHz MaxTrac from Trunking to Conventional operation By Robert Meister WA1MIK Replacing the firmware, blanking the board, and complete initialization steps. |
| Converting a 900 MHz MaxTrac from Trunking to Conventional operation - An Alternate Method By Greg Stahlman KJ6KO This article assumes that you have read the article above first. |
| Converting a 146-174 MaxTrac or Radius to 220 MHz By Matt Krick, K3MK Yes, you CAN move a VHF MaxTrac or Radius LRA to 220 MHz, complete with direct frequency entry in the RSS. This is NOT a beginners project, it requires serious surgery, access to a milling machine, and is best done to a radio that has a blown up PA deck. |
| Converting a low-band MaxTrac to Six Meter Operation By Robert Meister WA1MIK All of the steps necessary to make a 42-50 MHz radio operate in the 46-54 MHz range. Two radios were converted; the trials and tribulations, plus the results, are summarized here. |
| The Ontario Hydro Low-band MaxTrac 99-Channel Conversion By Robert Meister WA1MIK Documentation and procedure for converting a 42-50 MHz low-band radio. |
| Permanently Disabling the Extender on a Low-band MaxTrac Radio By Robert Meister WA1MIK A simple jumper disables the noise blanker. This is necessary for radios that will be used as base station or repeater receivers. |
| MaxTrac Transmit PL Mute Circuit By Robert Meister WA1MIK A simple circuit that immediately mutes the transmit PL tone. Especially helpful on radios that don't have a 16-pin accessory jack. |
| Converting a MaxTrac 146-174 MHz radio to 136-162 MHz for APRS use By Robert Meister WA1MIK Some MaxTracs work on 144.39 MHz; others do not. Bob analyzed the radio's performance on both range splits and tells you what needs to be done to improve operation below 146 MHz. This was suggested by Scott KBØNLY who modified a bunch of radios in his area for APRS. |
| Getting a Line Output signal from a MaxTrac radio By Robert Meister WA1MIK Often, MaxTracs are used to monitor police and fire calls in garages and fire departments. These are usually noisy environments and amplifiers and loudspeakers are installed to boost the signal. As always, there are multiple methods of interfacing to MaxTracs, but by far the hardest unit to use is the one with the 5-pin accessory jack. Here's a fairly painless way to get the desired signal out of such a radio. Step-by-step instructions are provided so even a technician who's unfamiliar with the radio can make it work. |
| Adding a Flat TX Audio Input to a 5-pin MaxTrac or Radius By Robert Meister WA1MIK Only the radios with 16-pin logic boards have a flat TX audio input. Three extra components give you the same functionality on 5-pin logic boards. |
| Getting Discriminator Audio from a 5-pin MaxTrac radio by Scott Withrow, KC9LQV MaxTrac and Radius mobiles with 5-pin accessory jacks are often overlooked because they lack signals such as discriminator (flat) receiver audio. Scott duplicated the circuitry from a 16-pin radio and added it to his 5-pin radio to get flat audio out of it. This article shows what he did. |
| Why the receive audio is lower on some MaxTracs than others by Robert Meister WA1MIK Analysis of the circuit and component value measurements solve this mystery. |
