[Elecraft] Audio levels in K2

[John, KI6WX]

There is an alternative way to increase the K2 audio output to headphones.
The K2 RF board contains series 82 ohm resistors at R35 and R36 to reduce
the volume for more sensitive headphones.  If you have low impedance or
insensitive headphones, the value of these two resistors can be reduced to
give you more audio output.

There is an easy way to check if this will help.  Plug your headphones into
the K2 external speaker jack on the rear panel.  If you now have plenty of
volume from the headphones, reducing the values of R35 and R36 will fix the
problem.
