I have a like new Motorola CDM1550 that the Control Head has become unresponsive. It will no longer allow me to use any of the buttons on the control head.

With some help from a few people to get me past a couple of walls I ran into, I was able to figure out how to use a CDM as a station alarm for when the tones go off. This radio was pulled out of our ambulance because it stopped making PL tones on transmit, but it decodes PL fine and receive...

Sorry I tried looking around quite a bit but I'm having trouble finding what I'm looking for. Being we use our radios on a shared frequency with our own PL, is there any way where we can program the CDM radios to enable Monitor mode when the mic is taken off the hook? Just by looking at the mic...

After several months, and fully dedicating a weekend to this project, I have pieced together from various sources (especially this forum), enough information to make an Accessory Port programming cable for the Motorola GM/CDM radios that will work with the generally available FTDI based RIB-less...

I am aware of the repeaters turn off code, pl settings, and lower end motorola repeaters. This issue is common when newer radios equipped with a active key loaded ucm or mace key transmitting in analog clear using post mdc data will emit a nasty burst if mdc is not muted and in any case muted...

My local Fire department came to me and they are trying to get a cross-band repeater up in a truck so mutual aid can talk to them as cheep as possible. the fire dept uses UHF for fire ground operations and have tk-790 remote head for use in the neighboring county. they want me to hook up a...

I have a CDM 1550 LS+ that I am trying to program with both commercial Public Safety as well as Ham freqs. The software gives me the FCC 12.5kz notice as soon as it starts programming and I cannot get around it. Any ideas. I have tried both .08 and .09 software.

I am currently having an issue where i get the following on-screen error: "Couldn't open port. Check weather device/RIB are powered on or not, and the device to RIB, and RIB to PC connection is ok." Where i did in fact have the 1250 on, i was trying multiple com ports (1,2) which I'm using a...

How can I make the Decode ID disappear faster.

I bid on a cdm 1550 on eBay and have won it. I didn't do alot of research on the specific model #. They gave me the freq it covered and I understand not all the 1550's are 160 channel. Anyone have insight into this model # AAM25SHF9AA5AN

So this is what I am looking to do... There are 2 widely used freqs that I scan but get tired of having to use nuisance delete to kill the trivial chatter, I only want to hear the dispatch with QC-II tones. I have the tone settings that dispatch uses when giving out the call, how do I set...

I've got a CDM-750 installed in a CDM-Series control station. The radio's internal speaker is disabled as to not compete with the station speaker. The problem is that when I plug in a headset, while the headset works fine, the station speaker also continues producing audio. I called Motorola...

I have programmed a few CDM1550's not the LS model and it seems to have a couple difference which I am trying to work out see below, any help would be appreciated: Model AAM25SKF9DU5AN Have a couple programming questions: #1 I am not going to be using the trunking features can i disable...

i have a question about the scan list and zone feature on the Motorola CDM 1250. I can get the scan to work in zone 1 but when i go to zone 2 to try and scan them channels it goes back to zone 1 to scan them. Is there any way to scan zone 1 and zone 2 on its own? I cant figure it out is there...

Where/What is the setting to adjust the squelch in the CPS software for the CDM1250? We got a new radio with the same freqs we have been using for years and now it's picking up (barely braking squelch) transimitions from ??? where. I'm somewhat familiar with the CPS software as I have adjusted...
