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."
