I think, not sure, that a majority of WINMOR testers are NOT experienced digital mode operators. By that I mean they may be RTTY or PSK31 operators but mostly come from the packet/pactor world. I am thus guessing that many are not familiar with other ARQ modes. This is based, in part, on several comments that I have seen from beta testers of WINMOR. Several have been "turned on to ALE 400 " by ALE junkies like VE5MU and K2MO.
