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.
