[Elecraft] question for psk users

[GLEN BROWN]

There was a question posted about power level and IMD when
transmitting PSK31.  I recent built a pskmeter kit and checked out my
signal.  I found that the 5-bar rule of thumb for the K3 is good for
up to about 70 watts.  IMD remains below -27db.  Above 70 watts drive
must be reduced.  But you shouldn't ever use that kind of power on
psk, anyway.
I drive my amp with 25 watts, so I just leave it there and run psk
barefoot.  That's plenty of power.
