Question about Motorola GP300 Compatible 2 Way Radio Battery Eliminator

3 Answers

GP300 Radios Hi there, I wonder if you can help me, I recently acquired 3 GP300 radios all programmed to different channels, I then purchased a rib-less programming RS232 cable which came with software including a windows version however, I cannot get the radio to talk back on the comms port, I have tried various baud rates and fiddles including the comms port utility, do you know if I can program the radios using a Win98 boot disc in DOS mode? Thanks and regards Dave W

    Hi Benimur,



    Thanks for your prompt response and suggestions, I've tried adjusting the bios settings and also slowing my pc down with cpugrab and using dosbox, still no luck I'm afraid, the Maxton RPC-M300 interface shows data flow with a green LED which flashes as the PC attempts to access the radio so I'm guessing there is out-going serial comms just nothing back from the radio.

    Can't think what I am doing wrong here.

    Going to try your Win98 start-up disc idea next.

    Thanks again for you help.



    Best regards

    Thanks to the both of you for asking, I have now managed to progam the radios, I needed to use a Win98 boot disc then default into DOS, select com 2 then program the radio from there before cloning the settings onto the other radios.

    Thanks again

    Dave

    Hi and welcome to FixYa,

    Initially, I believe you would have better chances running pure DOS (F5/8 before Win98 starts, I think 6.21 DOS version). I seem to remember also, that I always use COM2 perhaps because COM1 was often reserved for the serial mouse then. Having said that, you may want also to check in the CMOS/BIOS if there is even a COM2 or if it is enabled and that it is set to use IRQ 3 and I/O 2F8H.

    Would appreciate an update, curious too.

    Good luck and Thank you for using FixYa.

I recommend you **** can the USB cable and get a RIB and Rib cable. The GP300 Motorola software is available online for free (I can give you the web page address) and works just like the real Motorola software. I have programmed at least 20 GP300s with it with no issues. A RIB is the only way to go. Everyone has nothing but trouble with USB cables. Particularly with newer radios like the CP200.

Programming GP300 radios

Using an XP desktop with a COM port

Install DOSBOS 0.74

The program I use is called GP300std.exe

Copy GP300 folder to c:\

Plug in the cable with the GP300 RIB with a 9v power supply

Ensure it is in COM1

Go to Start /Progs/DosBox-0.74/options/Dosbox 0.74 options


Scroll towards the bottom of file and replace

Serial1=dummy

with

serial1=directserial realport:com1

save


when you open Dosbox drag the top window to one side and hit CTRL-F11 x11 and CTRL-F12x1 this will give you a CPU around 440 cycles.


Then type

Mount c c:\gp300

C:

GP300

The program should launch

Space bar

From here you should be able to read a preprogrammed GP300

F3 / F2 will read

Then F5 F5 will clone the radio.

Else F10 to go up one level then F4 to edit it.each mode is equal to each channel.

Once you've set the channels you can use F8 to programme the original radio or F5 to clone it.

Talkabout MH230R does not Receive or Transmit on channel, can just Transmit (only clicks when Recieve) when programmed 2 channels higher (i.e. all radios on 5-3, one is on 7-3)


Strange. Could it be any of the radios are from different countries? The channels are not worldwide. For instance, Canadian radios are on different frequencies than USA radios. They look identical.

I recently purchased a couple of second hand Motorola Two-Way Radio DP3601 which are programed to 10 channels. How can I reprogram them or reset each to factor settings


Sorry to report there is [ No ] Reset line on a GP300
as what one might want to see on a Computer.

So long as you have a stable programming computer
platform to work from, you should be able to restore
the radio by Cloning one radio to the other. The radios
must be identical series.

There are some other proceedures, but much more
complex to detail here....

If you can hunt down the GP tools , that may be able
to help, but those tools are not supplied by ( or licensed )
by Motorola.

How to reprogram two way radio, its a motorola gp 339 and its set to 5 channels from when i brought it, can i reset it or reprogram it to normal uhf channels?


In order to reprogram this Motorola GP339 you need to have a programming software, radio interface box and programming cable for this radio then you can read and change frequency in it. To reprogram to UHF channels this radio must be in UHF band. Good luck!

GP300 frequency programing


Here is what you would need: RIB (radio interface box), HKN9857 programming cable and HVN9128 programming software. You are correct the software is only capable of running on a DOS box, such as a 286 or 386. The software mentioned is Motorola proprietary and is available to Authorized Motorola dealers by subscription only.

The book also shows a cloning cable HKN9755 as being available. Don't know anymore details on it.

Lastly, the cost of programming to your FCC assigned frequencies would be approx. $15 per radio, and less for cloning like models. It might be less expensive to have the radio programmed by a dealer. Just an FYI.

Radios dont recieve from each other..


The buttons you are referring to are programmable buttons, and it would depend on how they are programmed. In most cases depressing the buttons will not change the radio in such a way you could not communicate. When changes are made, they are changed back to normal by shutting the radio off and turning it back on. See page four of the owners manual.

You might want to read the section on the light on the radio on page 3. It may help.

Here is a copy of the owners manual: http://www.motorola.com/governmentandenterprise/contentdir/en_GB/Files/ProductInformation/6864110B13A_GP340_BUG_Multilingual.pdf

Other questions which come to mind: Have you changed antennas recently? Have you tried the radios together on all channels? Have you tried the radios in a different area? Have the radios been reprogrammed recently? Do you use a repeater? If so, the repeater may be not working or malfunctioning, or you are out of range, check with your service provider.

Motorola GP300


Hi,

The Motorola GP300 needs an external device to program the frequencies assigned to the channels. All other features and functions are also accessed (enable/disabled) in the same fashion.

To start with, you would need programing interface that attaches to the back of the unit once the battery is removed. This also provides the power to the radio as well as the data connections. The interface is called a Radio Interface Box (RIB). Aside from the power leads, it has also a multi wire cable that is terminated with either a 9pin or 25pin serial plug that plugs in to the serial port of a PC.

Likewise required is a specific Radio Service Software (RSS) package(s) that is appropriate for a Motorola Radius GP series. This should be run on a personal computer capable of running pure DOS.

On running the RSS, all parameters can be adjusted and configured to your preference like Ch1 to be set to 456.789 MHz, CTCSS 108, etc. Having said this, then it is just a matter of repeating the programming to all of your radios.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
