Hi, I have been pulling my hair out trying to figure out a way to accomplish something. Any help you can give would be greatly appreciated. I have a fleet of buses each with a CDM1250 installed as well as a CDM1250 at our dispatch office. I am trying to figure out a way to set things up so that the drivers will not be disturbed with radio chatter. We are finding that drivers are turning down the volume on their radios, or worse yet, changing channels to avoid hearing all of the traffic on our frequency. I would like to use MDC-1200 selective calling to allow the dispatchers to selectively call a specific bus. That's pretty straight forward. Where it gets kind of weird is this, upon receiving a selective call, I would like the drivers response to also be a selective call back to base so that other drivers do not have to hear either side of the conversation. I would also like like to silence the selective call alert tone that sounds every time a radio receives a selective call. I know that you can turn this off in the radio's menu, but I would like to keep the alert tone enabled for MDC call alerts. From what I can tell, it's either all or nothing as far as silencing tones goes. I would like to give the drivers an option to monitor all of the traffic if desired, perhaps by changing to a different channel that has OR Rx signaling squelch instead of AND. Maybe I'm going about this all wrong. Suggestions? Thanks.
