ONE OF MY CP200 RADIOS HAS A STEADY SQUELCH SOUND ON ALL 4 CHANNELS, HOW CAN I FIX THIS?

Your radio is liquid damaged and is not economical to repair. Sorry for the bad news, happens all of the time http://forums.radioreference.com/motorola-forum/187778-radius-cp200-orange-amber-light.html

The CP200 is a dealer programmable radio which was available in UHF or VHF. You would need the UHF model to match. Then the radio itself would need programmed to the same frequencies as the T5720. This requires Motorola proprietary software, cable and radio interface box (RIB). Your best option would be stopping by your nearest dealer to have it programmed.

can you increase the volume? did you try the morse code button beep beep? are both units on? 10-4 big daddy truck nuts Over and Out

Both radios require appropriate programming software and cables. Your CP200 would need to be a UHF model in order to match the CP200. Your best option would be visit your local dealer or contact an online repair center for help in programming.

If your model number starts with AAH50R... the answer is yes. The CP200 could be programmed to match your RDU.

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

Best regards.

If your CP200 has a model number beginning with AAH50R it can be programmed to match the RDU2080d. If your CP200 model number begins with AAH50K, then the answer is no.

The letter R in the model number indicates it is UHF, and on the RDU2080d, the letter U in the model name indicates it is UHF. Both of these radios are programmable, and could be reprogrammed to match one another, if both UHF.

Best regards.

Hi Kate,

The short answer to your question is: no, or "not readily". Here's why:

The Motorola 4900 radio operates in the FRS (family radio service) and GMRS (general mobile radio service) in the UHF band. This radio will work with any other FRS / GMRS band radios (no reprogramming of transmit and or receive frequencies is possible for these radios). The trick is that the numbering of the channels may differ from brand to brand ie: Ch1 on your Motorola may not necessarily be Ch1 on a Midland radio or other brand. A complete list of the frequencies and channel assignments for FRS /GMRS can be found on Pg. 17 of the manual. It is important to note that without a valid GMRS license, you are prohibited from transmitting on the GMRS only channels (Ch 15 through Ch 22). The combination GMRS/FRS channels (Ch1 through Ch7) and the FRS only channels (Ch8 through Ch14) are for individuals and family members that do not have valid GMRS licenses. If this is you, you should limit your transmissions to Ch1 through Ch14 only, as FRS does not require a license in the US. Unlicensed use of GMRS only Ch15 through Ch22 can result in fines and imprisonment if caught by the FCC.

Further complicating the issue are the so called "privacy tones". This is simply a very low or "sub-audible" frequency that is sent whenever transmitting. Motorola calls these "Interference Eliminator Codes". When another radio receiver is set to listen for a particular privacy tone, it stays silent until a transmission with the exact same privacy tone is detected. Again, these tones are listed in no particular order, but are generally listed as 1, 2, 3, etc. or a, b, c, etc. instead of the actual frequency in hertz. You can selectively set your radio to transmit & receive one of the 38 codes or, set the code to "0" to communicate with radio that do not offer these privacy codes - or does not use the same frequencies for these codes. You can read more on Motorola's codes on Pg. 19 of the manual.

The Motorola CP200 radio on the other hand is a commercial radio, and requires computer programming with Motorola software. The CP200 is offered as both Low & High sub-banded VHF and Low, Mid & High sub-banded UHF radios. You would need to have a CP200 that is designed to accept the Mid UHF band (438Mhz - 470Mhz) frequencies in order to program the 462Mhz & 467Mhz FRS / GMRS frequencies into it. The final obstacle would be what is called "FCC Type Acceptance". The CP200 is probably NOT Type Accepted for transmitting FRS/GMRS frequencies, and as such the Motorola dealer doing the programing might balk at putting them in. You can read a spec sheet on the CP200 here.

I hope this helps & good luck!

It is seldom a CP200 loses frequencies/PL code settings. It is more likely the radio has a bad battery or another issue. The only way to reprogram the radio is by taking it back to a Motorola dealer, as they are all dealer programmable only. Sorry.

Best regards.
