[Elecraft] Digital modes - need clarification

[Julian (G4ILO)]

Most of the seasoned operators of PSK who use 100W transmitters seem to run
about 20W these days. It really isn't necessary to run more power than this
on this mode, and in view of the reported problems of drift reported by
K2/100 owners when the PA warms up I would think that it is particularly
important to try to keep things cool.

Assuming that you have a post SN 3000 K2 or have done the KI6WX mod to your
KSB2 you can use the power control to limit the output power, then adjust
the volume from the sound card until one bar of ALC is showing. Always
operate close to the centre of the SSB filter passband because filter
attenuation will reduce the drive at audio frequencies near the edge of the
bandpass.

I read the document PSK31_2.PDF but I'm still unclear on setting
transmit levels.  I assume you set the K2/100 power level to 50 watts or
less so as not to overheat on transmissions.  Then how do you tell when
you have the input level turned up enough?  And what should the K2 mic
gain be set at?
