Ok. I only found one place in CPS to enable Radio Mute, and that flag is set. I was attempting to determine if my problem with it not working might be related to a setting in CPS. Thanks.

Sorry for slow response on my part. I'll try to find time to test just pin 8 this weekend.

In the meantime, I noted that in this post: http://batboard.batlabs.com/viewtopic.php?f=1&t=3906&start=1 the author mentions programming the radio on F2, F3, F9, etc. for radio mute. I don't have any idea ...

PLEASE tell me you have a relay with a diode built in, or you put a protection diode across the mute relay. If not you may have smoked the MCS.

No, did not. But the relay has the following connections:

1. +12.5v input from MCS pin 14 (power to the switch)
2. +12.5 output to Dodge/Mopar PTIM ...

Any ideas? My bet is the ground from the radio on Pin 14 is bad, but I can't see how to confirm or how to fix it. Any suggestions?

I'm not sure what the deal is. I believe that I have the wiring correct, but I am getting some strange ...

Does anyone know if the YLN1120A SIU (System Interface Unit) will work to join 2 MCS2000 radios to a single MCS2000 Type III control head?

And if so, can the radios be setup as a mix of types?

I have a hi-band UHF Type 3 and a 900mhz Type 1 that I would like to join together if it's possible (the ...

Thanks for the quick reply.

Yes, conventional radio. Sounds like the Mod 2/3 issue is not a big deal. I was able to figure out how to re-program the func buttons and they seem to work fine.

Hello all. New MCS2000 user here. I am in the process of learning how to program my MCS2000 UHF low power radio (25w).

I'm stumped on one particular problem. The radio is remote-mount installed and working. But CPS shows it as a Model II though it is actually a Model III. The radio was originally ...
