[Elecraft] question for psk users

[Jon Perelstein]

Eric KG6MZS asked why wouldn't you run more than 70w on PSK

Because with the close spacing of signals in the various PSK  sub-bands, a
signal of more than about 50watts will completely annihilate all the other
PSK signals and make that sub-band unusable for everyone else.  The rule of
thumb for being polite on PSK is to operate 25-30w max.  I won't claim that
there aren't some who are operating more (you Cuban stations know who you
are), but many/most of us will avoid QSOs with people who are obviously
running 50w+
