ORIGINAL MESSAGE: REPLY: I can't speak for the ARRL but pulse tuning does not "sag" the power supply enough. You could pulse tune first and then tune at full carrier, but why bother? Just tune full c

ORIGINAL MESSAGE: REPLY: Another way to look at it is that full carrier tuning for SSB gives you a wee bit more "headroom" than pulse tuning. I don't think it's good to try to squeeze the last tiny b

ORIGINAL MESSAGE: REPLY: Because tuning with a full carrier and then operating with a normal SSB duty cycle gives you a wee bit of headroom to avoid clipping and splatter. I don't believe in tying to
