I have googled and search this forum till my eyes are dry.
1.) I have a CDM 1250 that I bought used knowing that the seller told me there was no speaker audio. Besides RX/speaker audio it works and transmits fine. Seller stated it was originally used as a paging radio and he used it for a APRS transmitter. I paid $40 for it hoping that it was just a setting in CPS cause I had another CDM that had no audio until I changed the RX from flat audio to filtered audio... well I have now tried changing that and every setting in CPS with no luck, the radio also has a external desk speaker cradle with proper accy plug and no audio out of it either (it does work when I put another CDM radio on it). I have also changed ribbion cables and internal speaker....still no luck. Any Suggestions?
2.) I have a CDM 1550 that will not power on by itself, it was set for ignition sense but I was able to take a heat gun to the board of it and after getting it hot (in attempt to reflow it) I was able to power it on, BUT it would only stay on for about 30 seconds then become unresponsive to keypad, etc. power off and won't come back on, heat it up again and was able to read the radio with CPS, turned off ign sense in CPS, heated it back up long enough to put the changed programming into radio. Any suggestions of fixing this one?
3.) If the 1550 can't be fix, would it be possible to transplant the component(s) for speaker audio from the 1550 to the 1250 and what would the component(s) look like? I do have the detailed service manual downloaded, but I get lost reading those. Thanks.
