[Elecraft] K2/100 With W2IHY Equalizer

[Guy Olinger K2AV]

Read the manual for the W2IHY equalizer and follow the procedure to set it
for microphone bias voltage.  For the older model, on the bottom of the
unit there is a little round hole labeled MIC IN PWR JUMPER.  Move the dip
style jumper with a pair of tweezers or fine tipped needle nose.

73, Guy.
