[Elecraft] switch to another microphone using a macro?

[Dick Dievendorff]

Hello, Werner!

I would recommend a pair of macros, one to select the front panel microphone
and another to select the rear panel microphone.

Each macro might need to "toggle" the high/low sensitivity settings and the
bias.  These aren't going to be "idempotent" macros. 

I don't have an SM-8, but I presume from your question that it requires
bias. I don't know if it requires High or Low, but let's assume that it's
different from the rear panel microphone.  If H/L doesn't change, it's a
little simpler.

To shift to the back panel Proset with HC-4, you'll need to change the
microphone from front to back, maybe change bias, maybe change the High/Low
setting and perhaps set the microphone gain setting.  You could extend this
to change compression and/or VOX settings as well.

You need to be in a voice mode for this to work (you can't change microphone
settings while in CW, for example).

MN053; opens the "MIC SEL" menu item.
SWT11; will simulate a "tap" of the 1 button, which toggles between H and L
settings.
SWT12; will simulate a "tap" of the 2 button, which toggles between bias on
and off.
Rotating VFO A will shift between front panel, rear panel, and line in.  You
simulate that with the VFO A UP; or DN; commands.

So the command sequence MN053;DN;DN;MN255; will switch to the Front Panel
microphone (no matter where you started).
MN053;DN;DN;UP;MN255; will switch to the Rear Panel microphone (no matter
where you started).

MN053;SWT11;SWT12;MN255; will toggle both high/low and bias on/off.

MG is the microphone gain setting.  First set the gain manually and then
using the K3 Command Tester type "MG;" and it'll show you the current
microphone gain, perhaps MG035; as the "current" setting.  Do this for both
microphones.  Suppose the Heil Proset needs gain of MG050; and the SM-8
needs MG035; (I'm just making these up).

Now one macro that switches to the front panel might be:

MN053;DN;DN;SWT11;SWT12;MN255;MG035;

This chooses the front panel microphone, taps the H/L and bias to change
them, exits the menu, and changes microphone gain to 035.

Another macro that chooses the rear panel microphone might be:

MN053;DN;DN;UP;SWT11;SWT12;MN255;MG050;

This chooses the rear panel microphone, taps H/L and bias to change them,
and sets Microphone gain to 50.

The only problem is that the bias and High/Low are "toggles"; their action
depends on where you started. You might need to press the same macro button
again if the wrong bias and/or H/L has been chosen.

Does this help?

Subject: [Elecraft] switch to another microphone using a macro?

I have an Icom SM-8 microphone attached to my K3's front panel and a Heil 
Pro Headset with HC 4 element plugged into the rear panel. Depending on 
working conditions and my mood I sometimes prefer one or the other 
microphone. 
The procedure requires to change Bias and sensitivity in the microphone 
menu which takes quite a time. 
I'd like to create a makro so I can switch from one 
microphone to the other with a shortcut. I did not find the necessary 
commands. 
Is this possible at all?
