Motorola UHF CP185 Transmitter Frequency Error Adjustment

It seems that this is a disposable radio since the tuner software has no provision or category for adjusting the frequenct error caused by component aging. Does anyone know of a way to adjust the frequency error besides sending the radio to Motorola Depot for repair for $145 flat rate out of warranty repair? Thanks David

You can indeed adjust the frequency error on the CP185. You will need a very small (preferably ceramic, but you could get by with any) screwdriver. Use some alligator clips to power on the radio with the battery not attached to the back, and peel back the small circular metal sticker. Under it you will find a very sensitive potentiometer which you can adjust with your screwdriver, while transmitting, to fix the frequency error.

Hi David,

If as you say the radio is a cheapie, so put it in your spare parts box and get one not so cheap.

But, as you say, the cost of repairs can be expensive, but this is dependant only by the quality of the radio being serviced.

The better the quality, the more reasonable the price, I've found.

I hope this answers your query to your satisfaction.

Cheers,
Peter

How do I connect Motorola CP185 two-way radios?
Yes, they must be programmed by a dealer to match your existing radios. Hopefully you purchased the same frequency band: VHF or UHF. I f they do not match that, they cannot be programmed to match. I don't know of a single 2 way dealer who would let those go out of their store without programming. Since you bought them elsewhere, another warning is they must be approved for the country you intend to use them in. You may be better off returning them and starting over. Many dealers, such as our store include programming at no cost when purchased from us. Call around to get some prices.

DECODING MODEL NUMBER/FREQUENCY RANGE
This is the model number for a UHF Motorola CP185. Specifically, 16-Channel, 4W Model 435-480 MHz. The only way to determine the frequencies programmed into the radio is to have the radio read-out by an authorized Motorola dealer or other entity with a subscription to the software, as well as, a radio interface box (RIB) and appropriate cable.

Best regards.

How do I know if my Motorola CP185 is UHF or VHF without taking it to a dealer for programming?
Hi christo,

Yes the serial No. usually indicates the frequency band the radio works on, but not always, because a lot of radios nowadays can operate on both VHF & UHF, so not being familiar with your model, I can't give you a definitive answer.

I do have the feeling, for what it's worth, that it is in fact a UHF band radio, but don't take that as gospel.

Anyone else reading this post is most welcome to assist in helping a friend out, we would much appreciate your input, thanks.

Hang in there my friend, there will be an answer soon.

Cheers, Peter

I'll look into it further as well....

I have a Motorola Axu4100 , I want to change the frequence that I currently have on this radio to a Motorola CP-200...just wondeing if these two radio can work together....
Hi
Motorola CP-200 have frequency range 
VHF: 136–162, 146–174MHz;
UHF: 403–440, 438–470, 465–495MHz depending on the model
Motorola AXU4100 have frequency range 435 - 480 Mhz
The first model has a wider frequency range so it is best to include transmitter Motorola Axu4100 to transfer and try to receive signal to Motorola CP-200

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!

How can i tell if i have a UHF radio or VHF radio
You can use the model number to tell if you are VHF or UHF. You will still need to know the frequency(s) and PL code(s) your radios have to get radios to match.

VHF model number starts with P93.
UHF model number starts with P94.

The current replacement radio for the SP50 is the CP200. It is construction grade and was made to replace the SP50. There are other radios which will also match the SP50 including (but not limited to) the BPR40 and the new CP185.
