Motorola rdu4100 radio.I tried to program a channel to a frequency.I connected the programming cable,read the radio,changed the channel frequency, write to radio,now the radio just blinks red&orange.

Here's a link to the user guides for each radio: http://www.mytoolstore.com/motorola/rdx_userguide.pdf

It would be easiest to read out the programming from the RDU4100 and then program the MU21 to match.
Best regards.

Dont think it will but take a look at this manual

https://www.motorolasolutions.com/content/dam/msi/docs/business/products/two-way_radios/mobile_radios/_documents/rdx_series_two-way_radios_user_guide_rdu2020-rdv2020-rdu4100-rdv5100.pdf

or download the software from

http://acsradios.com/resources/programming-software/

you will need either a serial or usb programming cable

hope this helps

If your CP200 is a UHF model the answer is yes. Both radios are dealer programmable to most frequencies between 450-470 MHz.

Hi Mario,

Have you posted on the Cars & Trucks forum, they may be able to assist, but I can't help as it involves a car setup.

Sorry.

Cheers,

• HI, I can help.

• This is a radio that can only be programmed with the use of a computer interface. The problem is that this unit has been discontinued. http://dogbytecomputer.com/motorola-axu4100-4-watt-uhf-programmable-radio.html there is a radio out that has "replaced" this on if you will http://dogbytecomputer.com/motorola-rdu4100-uhf-4-watt-10-channel-on-site-two-way-radio.html both of those radios program the same way. However to reset that radio to default or add any frequencies there is no way to do that without the interface.

• You will have to contact an authorized Motorola dealer such as http://www.buytwowayradios.com/products/motorola/motorola-ax-axu4100.aspx or any reputable two way radio store in your area. Those radios are still very programmable. I wish there was some way around this but there is not and Motorola gets very grumpy when unauthorized people end up with their interface because it is in fact quite the money making racket.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

Reset to Factory Defaults (Pg. 34)

Reset to Factory Defaults will set back all radio

features to the original factory default settings.

To do so, press PTT, SB2 and SB1

simultaneously while turning ON the radio until
you hear a high tone chirp.

Programming instructions begin on page 36.

Best regards.

Hello,
This radio comes with programmed channels and tone codes programmed into it. Should it still be stock the the diagram below is what you will use. The tones programed into are there to prevent someone on the same frequency from interfering with your conversation. It's a way of isolating the frequency. These are adjusted by the A,B,C,D You will know what frequency it is by the channel indicated. As for weather or not it will communicate with a Motorola talk about the answer is no. This radio is a VHF frequency and the talk about is MURS.
Regards, Tony

Channel - Pre-Loaded VHF Frequency (MHz) - Code (Hz)
1 151.6250 67.0 2 151.6250 77.0 3 151.6250 88.5 4 151.6250 179.9 5 151.6250 None 6 151.9550 67.0 7 151.9550 82.5 8 151.9550 94.8 9 151.9550 179.9 10 151.9550 None

I don't think that you could program/change the freq of your Motorola GP2000 manually since newer Motorola radios today everything is done by computer and programming sotfware. You need to have software for GP2000, radio interface box ( RIB) and programming cable for GP2000 radio and these devices are not cheap. The best way is to contact a local repair shop to have it done for you or find a two-way radio technician, he could do this if he has all the test equipments required.
Good luck!

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!

The "others" have an Interference Eliminator Code ( aka PL or code) applied to their frequency. You would need to program the same "code" into your radio.

Here is a link to the user guide: http://www.mytoolstore.com/motorola/rdx_userguide.pdf

You can with the manual determine how to program and/or read-out the radios.

Best regards.
