Note: For PSK and other operation,  you want to set things to the level 
where the 5th bar just comes on -- or  just doesn't.  If you have only 4 
bars in digital modes, that's OK.  With less than 4, you are under- 
driving things and the ALC will kick in to  bring up the power level to 
the amount you requested.  If you try and  trick the system and run with 
*zero*  ALC bars in PSK31, the ALC has to  work hard to give you your 
requested power - or maybe it will think there is  insufficient signal to 
work with - and your Tx S/N may suffer.  So,  *please* set it to 4 bars 
in soundcard "digital" modes. ]


Did you  mean for these instructions to apply to using the DATA A mode?  If 
so, I  find this almost impossible to do - I have to crank the Line In level 
all the  way up and set the MicroKeyer to almost maximum to get 4 bars on the  
ALC.   When I do, my output meter reads 50 watts even though the max  power 
setting on the K3 is 20W.  That just doesn't seem right.

The  suggested "4 Bar" system does seem to work using SSB for the PSK.
