Motorola CDM1250 Retuning

[715143]

Hello, I have two UHF Motorola CDM1250 that are currently tuned to work as a repeater.
I recently got a GR1225 repeater unit and would like to use the two CDM1250 as regular mobile radios one for the mobile and one for the base.
I tried to program as one would normally program for regular use but for some reason it's not working the way it should...
For some reason I can not operate on Repeaters.
These radios are currently tuned to operate as a repeater.
I would like to use it as a Regular Mobile Radio.
I also noticed it is not transmitting the 40-45watts it's capable of doing.

I would really appreciate if some one can let me know how to get these radios to work.

Thanks for all and any help.

Do you have the RSS for the 1225 and the CPS for the 1250? If so, you can email me the code plugs and I can look at it for you

 

[715143]

I can email the code plug for the CDM but not the 1225 as that laptop has no Internet service.

 

[715143]

What's your email address so that I can sent the code plug to you?

 

[715143]

Could it be that radios need to be tuned once again? It was tuned to work on GMRS Repeater and I was told that in order for them to work as a regular mobile radio they need to be retuned.
I have compared a 1550 radio with some of the settings on the 1250 and still can't manage to get the 1250 to transmit on repeaters...

They should not need to be 're tuned' unless someone screwed up the alignment and calibration.

Just need to read the radio, then change the Mode to the frequencies and PL you need.

ALWAYS read the radio first, then save the 'codeplug' to a safe archive.

I already reprogrammed to my needs and still can't transmit on repeaters. I am being heard in Simplex frequencies but not on repeaters. Both CDMS Can't transmit on repeaters but they do RX ok.

I pm you my email address.

Most likely cause is incorrect programming of the transmit frequency or the wrong PL.

The same TX and PL that I put on these two CDM1250 , I also have it programmed into 2 CDM1550, two Motorola Spectra , one HT1250 and one HT1000. All work fine as they should except for the CDM1250.

I thought the same thing you did at first, but a look at the postings makes me think I think they are saying "tuning" when they mean programming.

 

[715143]

I have all my radios programmed the same way ( same TX/RX freq. and DPL/TPL ) I don't know why the 1250 won't key up any repeater.

There has to be something you are missing then. You best bet is to either take your radios to a service shop and let them look at it and your programming, or email your codeplugs to some here to help you.

However is sounds like to me that you don't have the transmit frequency and/or you PL/DPL set properly to access the repeater.

 

[WA0CBW]

Are the radios putting out any RF?

I have all my radios programmed the same way ( same TX/RX freq. and DPL/TPL ) I don't know why the 1250 won't key up any repeater.

" same TX RX freq " that may be the problem.

The transmit and receive frequencies are different, offset by + or -.

Example: 464.1 receive, and 466.1 transmit in the mobile radio.

 

[715143]

Sorry, what I mean by same is that each one of my radios are programmed the same as in TX 467.7 and RX 462.7 that's how I have my mobile, base and portable radios.

 

[GmanX]

Is the repeater programmed the same as the mobiles. The repeater tx and rd need to opposite the mobiles

Ignore me I can't read a thread apparently

 

[715143]

The repeater unit is programmed differently ( Opposite ) than all my mobiles and portables.

Some basic testing can determine if your radio is faulty. If you know someone with a service monitor they could quickly determine if the radio is transmitting, the RF power output is adequate, the RF carrier is on frequency, the PL tones being generated are properly deviated and on frequency. If no service monitor is handy you could use a watt meter to check your power output, current draw doesn't always tell the hole story. A frequency counter could be used to check you carrier frequency. You could use another known good radio setup to RX on your TX frequency with the PL tone you need and see if it passes the signal.

Maybe something is just hosed in your codeplug and you need to start from scratch. To do this save your current codeplug! Then look at the label on the bottom of the radio and record the model number and the tanapa number. Then go into the samples folder of your CPS and find the sample codeplug that matches your radio and right it to the radio. Then program one channel they way you need it and see if it works.

Good luck.

I tried to do what you mention about getting a different code plug from within the software, for some reason no matter which in I click on it all says
" Unsupported Model "
There was about 4 that have the name model number but ends in with A,B,C and D. All gave me the same message of unsupported model.
