Good instructions for the analog world.
There's one more way that works on most any computer these days....Even people
with direct USB connections to their rigs are having problems.
I would add this...and it should work on most any rig setup....
#1 Set WSJT-X to minimum power#2 Set audio devices (record/playback) to 0dB#3
Rig to 50% of rated power for CW (some rigs can do full power on CW, some can't)
#4 Rig gain to zero (MIC gain if you're input is the MIC, or USB gain if USB,
or Data gain if one of the DIN connectors)
#5 Click Tune on WSJT-X#6 Bring up WSJT-X power SLOWLY to max...you should
still see no power or very low output on your rig (assuming rig gain is at
zero).
#6 Bring rig gain up SLOWLY until you get 5W or so of power. If you don't see
power coming up then you have the wrong gain control. Then look at your ALC
meter. Whatever your ALC meter shows at this stage is where it should stay as
you bring up the rig gain. Some rigs show 1 bar of ALC (e.g. IC-7100), some
show 30-50% (eg IC-7300/7410), some show no ALC at all.
#7 Bring rig gain up and eventually you will see the ALC start rising....back
it down to the level you had at 5W. What ever transmit power % you have at
that point is all you will be able to transmit without ALC kicking in. It will
probably be 80-90% of your rated CW power.#8 Bring up rig power to full CW
power level and the ALC should stay constant. You can now adjust your transmit
power either from WSJT-X or the rig.

Exactly right. The last page of this link has detailed instructions for
setting audio levels that avoids distortion.
