[Elecraft] K2-Bias Resistor When Using Mic Connector Pin 1 for Soundcard Input

[W3FPR]

Jim,

If I understand your question in the subject line (but no text to detail 
your question) - then the answer is that it all depends on the 
soundcard.  If it has a DC blocking capacitor in the input, then all is 
well with the bias resistor in place.  If there is no DC blocking at the 
soundcard, the the bias resistor will have to be removed or a special 
cable with a DC blocking capacitor will have to be inserted between the 
mic input and the soundcard AF input.  A capacitor of 1 to 5 uF should 
do fine.

If this does not answer your question, the respond with more text 
instead of us trying to guess from just a subject line.

73,
Don W3FPR
