The repeater offers both local digital and connection to talk groups, called Reflectors, through an internet gateway.  Ham radio operators with D-Star equipment can use the local repeater function, but in order to use the gateway and talk on the Reflectors, it is necessary to register with the D-Star system.  This registration helps to ensure that only ham radio operators are using the gateway.

This Fusion repeater supports standard FM analog voice and Fusion digital voice, however, the analog users will not be able to communicate with the digital users. Digital and analog users cannot be transmitting through the repeater at the same time. Since the digial and analog users share a common frequency, analog users should set a CTCSS tone of 100.0 Hz to filter out digital transmissions from Fusion users. 

This repeater will be up for general use until at least March 2017.
