[RTTY] K3 AFSK power and ALC?

Wow, the big news is I have a K3 -- I bought one of Doug's (ZP6CW). Now 
to get ready for the big contest! I won't have the FSK working in time, 
so will be running AFSK.

The usual instructions are to advance the mike gain to JUST BEFORE there 
is any ALC indication -- worked fine with my FT757. But the technical 
notes for PSK on the Elecraft site say to set power level to whatever 
(20-30 watts) and advance the mike gain to where "3 or 4 bars of ALC" 
are indicated. This will result in a very clean signal. No special 
instructions for AFSK RTTY are given.

Can a K3 user help me? Would this work (actually, it does work but I 
don't know how clean the signal is): Set the power to 75 watts, fire up 
a CQ macro into a dummy load, and adjust the mike gain to "3 or 4 bars" 
of ALC reading?

With a little more power available I hope to go high and call CQ, for 
once! See you in the test.
