[Elecraft] K3: Mixer Commands?

[David Gilbert]

I saved all of those emails  ;)

Here are the commands that were published:

!bed1; =  main left, sub right (default condition)

!bedb; = main and sub in both ears

!bed7; = main in both ears, sub in left

!bef9; = sub in both ears, main in left

 From that set of commands, KB9BRJ deduced that four bits of the second 
byte in the command determined which channels were heard in which ear.  
In other words, for the command !bexx;,

bit 0 (LSB) = main left
bit 1 = main right
bit 3 = sub left
bit 4 = sub right

where a "1" in the bit position activates that channel.

Note that bit 2 is skipped, or maybe used for something else.

If you make a chart of 1's and 0's for the last two bytes you'll see 
that this fits.  I tried, for example, !befa; and got the sub in both 
ears and the main in the right ear, which was not a published command.  
It's not clear to me why the published command for "sub in both ears, 
main in left" was shown as !bef9; since !bed9; seems to do the same 
thing, as does !beda: for "sub in both ears and main in right".  Maybe 
there is something I'm missing there ....

Remember the caveat that these commands may not survive some K3 actions, 
such as power on/off.  I loaded the ones I wanted into the command 
macros of the utility program for easy execution.

73,
