New HF Digital Protocol to Debut at DCC
WINMOR, an HF digital protocol designed for use with the Winlink 2000 network, will be unveiled at the upcoming ARRL/TAPR Digital Communications Conference in Chicago, September 26-28.
According to developer Rick Muething, KN6KB, WINMOR will effectively eliminate the need for external PACTOR hardware. "This new protocol is implemented through a Windows application that uses a computer sound card for all the analog-to-digital conversion. It provides error-free ARQ transfers within 200, 500 or 2000 Hz bandwidths," Muething said.
In terms of throughput, Muething said that the 200-Hz WINMOR mode appears to equal the performance of PACTOR I. In WINMOR's 2000 Hz mode, its performance rivals PACTOR III.
"WINMOR is a work in progress," Muething said. "We won't be pulling the wraps off a finished application at the conference. We're close, though. I'd like to see on-air testing in 3 to 6 months."
Conference information and registration is available online or by telephone at 972-671-8277. Rick Muething's presentation paper, WINMOR. . . A Sound Card ARQ Mode for Winlink HF Digital Messaging, is included in the conference proceedings. Proceedings will also be available for sale on the ARRL Web after the conference.
