URI FAQs

Q: What is URI? 

A: The USB Radio Interface is the easiest and least expensive way to connect a land or mobile 

radio to nearly any host computer. This allows remote connectivity and simple internet access. 

Q: What type of radio can I use? 

A: Virtually any type of radio may be used including, amateur, business, public service/safety 

radios, plus GMRS, citizens band, and many others. 

Q: What types of applications is URI suitable for? 

A: Radios are often placed in inaccessible locations requiring remote access. Audio signals and 

digital controls may be passed through any available channel including but not limited to VOIP 

and Ethernet. 

Q: Can I use URI to make a repeater? 

A: Radio controllers may be replaced with a URI based system. Since URI is full-duplex, only 

one URI is needed for both transmit and receive channels. 

Q: How do I connect my radio to URI? 

A: Many transceivers and radio systems provide an interface connector for interfacing to external 

equipment. It is usually very simple to make an interconnection cable between this and the 25-

pin D-shell URI connector. If such a connector is not provided, internal modifications may be 

required to gain access to the required electrical signals. 

Q: How does the URI work? 

A: The URI contains a CM119A audio controller IC made by C-Media. (Older URIs used an 

equivalent CM108.) This is a high-quality full-duplex USB audio device with several general 

purpose I/O channels. The CM119A provides one channel of receive audio, and two channels of 

transmit audio. This allows support for many different radio configurations. The second audio 

output channel may be optionally used as a line monitor.
