Jan 08, 2018 Motorola Radius Gm300 Radio Doctor Download. 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.
I have a Motorola GM300 that I've been trying to reprogram for a while. The radio looks brand new witch has nothing programmed into it, it has never been used.
I've downloaded several GM300 programming files none of them have worked the software can't read the radio. I'm assuming that MS-DOS versions won't work for the GM300 that I have however I've not found any windows versions of the software.

I came across something in yahoo called Radio Doctor witch is Windows based and apparently runs under XP on a modern computer and it allows you to add more channels to the radio. I've not managed to find any download links for this fantastic software or any further info in regards to where to find the software. I understand this radio can go up to 40 channels witch is ideal for Amateur use on 70cm witch I plan on using this radio for as a back up radio. I'm really confused as to why none of the GM300 DOS based software will read the codeplug? Do I need to change some jumpers on the radio perhaps? My programming cable isn't the problem as I've used it to program other radios.
I've just dug out 2 old laptops from my attic unfortunately none of them are 486's but they are very old. Typically the one that had MS-DOS & Win95 installed has a bad hard drive and the other laptop has no OS installed at all. I used to have MS-DOS 6.22 on 3 floppy disks I wonder if there still available? Maybe I can download them. I was gonna throw these old laptops away but I'll think I'll hang on to them now I wonder how ebay sellers program their GM300's that offer free programming. Cheers irishlad that would be great if you can.

The Motorola GM300 can be re-programmed quite easily to allow use on our Amateur Radio bands. The radio is made in both a VHF and UHF versions, and makes an excellent 2mtr or 70cms mobile/base station radio.
Most of the radio's I have worked on have originally been 8 channel units. These can be modified to operate on 16 channels quite easily. The programming interface can be made for a low cost. All it consists of is a RS232 to TTL level converter, that connects between the serial port of your PC and the radio's microphone socket. Amateur Radio Conversion. The radio requires the Motorola Software which can be found if you ask around or search for it on the FTP sites on the Internet. If you can't find it then try your local Motorola dealer who should be able to help at a small cost.
You also have to make an interface, or purchase one. To program the radio onto the Amateur band, you can find some versions of software that have been hacked into allowing frequencies to be entered to bring the radio into the amateur bands which normally are just bellow the original working frequency.
However this depends on your version of software, if it's a un-hacked version then you have to press the key down when entering the frequency. You must release the key when entering the decimal point. For example to program 433.500MHz you will enter the following: $££.%)) on a English layout keyboard. (This is 433.500 with the held down. Fill all of the 0's in the frequency field. This example is the same for both the VHF and UHF GM300's. 16 Channel conversion.
(for 8 channel radio's only) To program the radio for 16 channels all you need to do is edit a file called GM300.MDF. You do this with the help of a Hex editor such as Hex Workshop. The file you need to modify is called GM300.MDF and can be found in the main directory of the Motorola software. Keep a backup of your original GM300.MDF file, just in case you make a mistake. I have made a small video that shows the Hex Workshop screen during the modification. This should help you understand the procedure of editing the file which when complete will give you 16 channels.
