Programing radios i have a xtn series model xu 2100 having trouble programing channels and frequnce with my spirit mu21cv help

Any Uhf Motorola business radio can be programmed to match. None of the toy radios will ever work. (GMRS/FRS)
Easiest to self program will be the the XTN, also called CP100, and RD (RDU) and even older Spirit and SP10 are possible, but harder. RD's are really hard without the programming cable, available from a dealer.

Here is a link to the user guide for the XTN style radio. http://www.123radios.com/manuals/xtnmanual.pdf

Programming instructions begin on page 18. You will need to set the frequency and interference eliminator code (PL code) the same on all the radios.

When you enter programming mode, you can use the menu button to walk you through the various options you can program.

Best regards.

Your local Motorola radio dealer should be able to help you with this.

The scan function on an XTN is not to be a scanner, but to scan between channels you have programmed into the radio. The scan feature is only available on the 2600 series. You can manually go to each channel and look for or listen for channel activity. Start with channel 1, when someone else is talking, there is a "busy" indication on the LCD on the radio. You can listen in by pressing the Monitor button. If you are using the factory defaults, you may hear someone without pressing the Monitor button.

Here is a link to the programming software http://www.radioserviceincorporated.com/files/1935423/uploaded/RDX_Series_CPS_R01-00.zip

And here is a link to the user guide http://www.astracomm.com/media/pdf/RDX_Display.pdf

The RDV2080 VHF with display would be compatible with the XTN series radios which have a model name starting with XV, as in VHF. Typically the RDV2080 ships on the default frequencies found in the XV2600. So if you have not changed your XTN frequencies/PL code they may match out of the box.

On a sidenote: The Motorola CP110 VHF is also compatible. It is an industrial version of the RDX radio. It has a few more channel capability and a replaceable antenna. It looks just like the RDX models, and it is the replacement radio for the CP100 and/or XTN.

All of the above mentioned models are repairable.

Any programmable UHF 450-470MHz mobile radio could be programmed to the frequencies of the Spirit MU series radios.

Your radios are 2 watts, so you would probably want to stay with a 1-10 watt, or 10-25 watt mobile radio, to have the best success. The current compatible model for Motorola is the CM200 UHF radio. If you are looking at a used radio, just simply watch for it to be UHF 450-470 MHz.

Then when you are ready to have the mobile radio programmed, the dealer (or programmer) will need to know the settings of your MU radios. These are easily read out over the phone, or in person by an experienced programmer.

would a MU21CV be a VHF or UHF????

Hi,

The problem of failing to power on can be caused by:
1. dead battery (may no longer hold a charge);
2. corroded battery terminals or connectors;
3. open wiring from the battery casing to the internal circuitry;
4. defective on/off switch; and/or
5. defective regulator component(s) on the main PCB.

On the other hand, problem on receive can be caused by:
a. defective or worn out volume control (if manual/rotary);
b. defective or worn out squelch control (if manual/rotary);
c. mismatch in PL or CTCSS code; and/or
d. defective internal speaker.

Most can be checked with the use of a continuity tester or a DVM. Repairs involve knowledge and familiarity with electronic components and circuitry and perhaps even the use of a soldering iron. Should you not be comfortable doing it yourself, perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of help. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
