[Elecraft] K3: Odd ALC behavior

[Bob McGraw K4TAX]

There's actually 3 places in the system where the audio level for 
transmit must be adjusted correctly.

(a)  SPEAKER  -  Just left click on the speaker ICON and set the level 
for about 35%.   Or right click on the speaker ICON, then select 
Playback devices.   Click on the one being used, normally Speakers USB 
Audio CODEC, select this and then select Properties and then Levels.  
You can adjust the level from here.  Again about -18 dB although your 
level may vary.

(b)  The PWR slider on WSJT-X  --  I find this to run about 50% to 75% 
however {see C below}

(c) The Line Gain in the K3S.   I use a value of 30.

All three of the above will affect the ALC number of bars.  If any of 
the values are at either the extreme minimum or extreme maximum values, 
you'll likely have somewhat a challenge in getting the levels correct 
and stable.

Also be advised if you should use the computer of other reasons which 
require support of the audio system, you may find that the levels have 
changed.   No fault of the radio, no fault of the WSJT-X application but 
just the way Windows works.  Just remember the approximate values and 
where to change and set them.
