I'll say this - my check, 65, as a phone check sucks. It sounds like 55 and I get lots of requests for repeats. On phone I would like my check to be 00. If my check were 00 it would suck on CW, so maybe I would use 55. Except for the rules. I'll bet it would make for at least a few QSOs worth of difference over 24 hours of operating. 73, Ken, K6LA / VY2TT
