Postby DAC » Thu Apr 24, 2008 7:27 pm

Is the cdm-1550, model : AAM25RKF9DP5AN, FCC ID : AZ492ft4830 worth modding?
What band(s) will it mod to?
How do you determine the frequency of Motorola transceivers? UHF or VHF?

Thank you for reading my questions!

Thats an R split(403-470) CDM - its not a 900mhz moto radio and I do not think there are any 900mhz CDM radios.
For other moto radios you have to go to the batlabs "radio specific" and click on that for other model info.


AAM25RKF9DP5AN
6th character = R
B = 29.7-36
C = 36-42
D = 42-50
K = 136-174
R = 403-470
S = 450-520

I have a picture of the radio, its just a mic and a radio, does this rig have the typical control head and large box transceiver or is the mic/unit control head all there is, I guess I'm asking if this is a two piece radio or is it a single unit?

thanks in advance?

It could be a two peice if you had the remote kit for the head but this is a forum for converting 900mhz radios for ham use so if you have anything further you should take it to the general forum.

Your CDM is a UHF radio, and it can easily be remote mounted using the proper remote head options, provided you remember to swap the ribbon cables between the heads first, and line up the marks (0) on the ribbon cables.

One stupid problem with the CDMs, is the control head retains the logic board and speaker, and those items are retained by snapping them into the head assembly, making certain you get a 'snap' to indicate they are fully seated, or the display will more than likely have blank areas.

The zebra strips used for the display are held against the board by snapping the logic board fully into the head assembly.

Removing the head usually means reseating the board and checking to make certain the display still functions properly.
