Colorado D-STAR folks, John Maxwell N0WBW was able to work 1.2 GHz "DV" voice from over 100 miles out from Mt. Thorodin with a 1.2 GHz corner reflector built by Dave W6OAL of "Ye Olde Antenna Labs" in Parker, Co today with an ID-1 on high power (10w?).
Exact range was roughly 115 miles. He wasn't quite able to make high-speed 128K half duplex "DD" data work at that range. He was line of sight from the top of the mesa called Cedar Point a few miles west of Limon, CO. A good sign that the RF portion of the 1.2 GHz combiner, duplexer, feedline, and antenna system at W0CDS/Mt. Thorodin was done "right". The Repeater is using a very similar but more compact/modern version of the same antenna. -- Nate Duehr, WY0X Sent from my iPhone
