[Elecraft] Making a Signalink cable for the K3's 8-pin mic connector

[Richard Ferch]

Slava,

If you are using a microphone input for data modes, adjusting the mic 
gain input for the data mode interface will affect the mic gain with 
your microphone. You will probably find this annoying.

The usual arrangement is to configure voice modes to use the front- or 
rear-panel microphone input, as appropriate for your microphone, with 
the mic gain level set properly for the mike, and then to configure Data 
modes to use Line In, with the Line In level set appropriately for data 
mode input. The Line In level and the microphone input level are 
independent, so adjusting the Line In level for data modes has no effect 
on microphone input levels, which is not the case if you use a 
microphone input for data modes.

If you use a sound card for voice keying, you can use the same sound 
card for Data modes. You would configure MIC+LIN to be on for voice 
modes and off for Data modes. By controlling the microphone input level 
to the sound card when you use it as a voice keyer, you can set things 
up so the Line In level that works for data modes is also the correct 
setting for voice keying in voice modes. You don't need separate sound 
cards or interfaces for Data vs. voice modes.
