I use the Autocom with a Motorola UHF radio and it works just fine. Consider purchasing Autocom push to talk cable/switch which gives the flexibility to use vox (voice activation of the radio) or push to talk. As a result, you can communicate with an on-board passenger without automatically transmitting. I mounted that switch on the handgrip of my left handlebar. The radio is stored under my seat. And, with 2 watts of power, provides excellent range. This is used in conjunction with an XM radio input to the Autocom. When my 2-way radio receives a transmission, it lowers the volume of the XM by 1/2. If you purchase the right cable, you can also tie your cell phone into the Autocom. You set the phone to auto-answer and when a call comes in, it totally mutes the music. When the other party hangs up, your phone call is terminated and the music returns.
