Thread: C250 Mobile Multi-Switcher

I have been looking at one of these devices to hook up to my existing radios and adding a new Whelen CenCom controller to help integrate and upgrade my system. Has anyone used this system before. I will be hooking up the following to the C250:
Yaesu FT-8900R
Cobra 19DXIV
Grecom PSR-800 (headphone jack)
iPhone (headphone jack)

I am wanting to get my system down to one mic while adding some functionallity. I have added a very bad and simplistic diagram as to how the system ideally would be configured. I am thinking though instead of hooking up the C250 to the CenCom with the PA input I would use the RAD input.
