System Fusion Repeater Installed

MAC System Fusion Repeater Installed

The METRO AMATEUR RADIO CLUB REPEATER on 147.315/147.915 has been upgraded to a new repeater, the Yaesu DR-1, supporting legacy analog FM and supports the System Fusion digital mode – a specific implementation of C4FM FDMA.

Thanks to Bob K0KVK, Lyam N9LVG, Arne W9FO and Vern K9VRG for installing and programming the new repeater in April.

Yaesu has chosen MAC and CFMC radio clubs to be part of a beta test program.  Yaesu sent us the radios. All we have to do is use them!
The new technology these repeater use is known as “mixed-mode”.  Essentially, it means “analog in = analog out -- digital in = digital out”.  Digital signals sound something like the tones from dial-up modems that we used to access the Internet, in by-gone days. 
The repeater upgrade is part of a unique opportunity to be a part of the field trials of an emerging technology, we encourage as much repeater use as possible – both analog and digital.  Your feedback is important.
