[Elecraft] K3 with Signalink or MRP40

[Don Wilhelm]

Gerald,

The Signalink is nothing more than a soundcard.
Have you plugged the Signalink output into the Line-in jack on the K3? 
Make certain the plug is fully inserted.
Then go into DATA A mode and set the MIC SEL menu to LINE.
Adjust the MIC Gain (now LINE IN gain) to produce 4 bars solid with the 
5th bar flashing on the ALC meter - You can do that is TX TEST mode so 
you do not transmit RF.
If the MIC GAIN is 'touchy' and at a very low level, go to the computer 
and adjust the soundcard level lower.  Normally a soundcard level of 
about 75% is workable - too low and the S/N ratio is bad and too high 
the soundcard can overload.

73,
