K3: Mixer Commands?

[Dave Zeph]

At one time there were several messages on how to set up the K3 Mixer to get
various combinations of MAIN and SUB receiver Audio out to Both, or Specific
Ears.

 

At the time I though I had an understanding of the syntax of the Command -
but I don't.

 

Could someone provide the complete syntax of the command - indicating the
different fields, and the values of those fields for the various
combinations of Audio Mixing??  I don't find anything in the Programmer
Reference and the original message posting (if I could find it) was a bit
confusing.

 

 

Thanks and 73, Dave, W9ZRX

I'm the usual source of this sort of thing, but I don't have the information
handy.  I'll be back home (and thus at work) on Wednesday.  Remind me then and
I'll see what I can do.

I located one post from Lyle on the subject.  I am certain it is not all
of the 'magic', but perhaps it will help until the commands are
integrated into the MCU code so the user interface is much smoother.
I have copied  Lyle's post at the end of this email.

The adventurous may try the following.  These commands do not stick
through power cycles, and may not remain through mode changes or other
commands.  In other words, the radio may revert back to normal operation
at any time  :)

If you want Main Rx in both ears and leave the Sub Rx in the right ear,
go to the command tester and type:

!bed7;

If you want the Sub Rx in both ears and the Main only in the left, type:

!bef9;

Be sure SPKRS+PH is OFF, or SPKRS=2, with these commands.

Enjoy!

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.
