Motorola Gp300 Gm300 Software Software Alignment Procedure

The old radios I got on ebay were a little off frequency, but it was easily solved by someone with the right equipment using the software alignment procedure.

Unfortunately, it will not recognize the USB - Serial converter in a DOS box.

The software actually sees the com port OK, but it cant read the radio.

Now I have to find an old computer with a serial cable and DOS to try to get this to work.

You need the RIB and the right cable with a TRUE serial connection running in TRUE dos to program the radios.

Running the dos window in the Windows operating system will not work.

BTW, if you happen to have a modern computer with an old fashioned serial (DB9DB25), you can get the program to work in a DOS box.

You cannot get it to work in a Windows command prompt, rather you have to download a real DOS virtual machine application.

Ive wanted to do this for a while but there are so many different methods online it confused me.

Some show simple schematics of a cable that goes right from the PC serial port to the RJ-45 with just a resistor and a diode others have many components.

Some use versions of the original software others use aftermarket.

Download it, buy that cable and try it out - I think youll be pleased.

Regarding the front-end on these radios: Im only using it on 440, but I think these radios really are pretty good.
