Welcome

Welcome to D-STAR Reflector 77.

This is the information website for D-STAR Reflector 077 located in Chattanooga, Tennessee, USA.

News & Update

D-STAR Reflector 77 is Now Cloud-Based.
For sometime, there had been plans to migrate Reflector 77 to a Cloud environment.  The recent East Brainerd Tornado (April 12, 2020) was the genesis of moving forward with those plans.  The data center which hosted the Reflector 77 server was damaged by the tornado and was without power and Internet access for three days.

Through the technical skills of Robin Cutshaw, AA4RC, and Gary Ownsby, AK4ZX, as of Friday, April 24, 2020, Reflector 77 is now operating in The Cloud.  It might also be noted that Gary is also funding the operations expense for placement of Reflector 77 into its new cloud environment.

What Does This Mean to Users?
As a virtualized reflector, Reflector 77 no longer resides in only one physical place but rather is spread across multiple cloud computing centers.  As such it is almost completely impervious to storms, power outages, and most technical faults which could (and did) happen to a server located in a single location.

Power & Speed to Serve the D-STAR Community.
Reflector 77 is configured identically to Atlanta’s Reflector 30 so it has the capacity and speed to serve as a major communications hub and as an alternate hub for nets.

Available for Use.
Reflector 77 is available for a variety of uses including nets and special events.  Just get in touch and we’ll do all we can to support your needs.
