[Elecraft] K2 Receive Audio

[wes Bolin]

I have a very nice K2 that I bought as previously owned.  It works fine on
SSB on
20 Meters.  The audio from the radio's speaker is low frequency for voice.
Sounds good on CW to me, but the SSB tone/pitch is like there is a LP
filter cutting off the
high frequencies.  When I have this situation with other
receivers/transceivers I find I can shift the BFO or Carrier Oscillator on
the filter slope and get audio that I like.
I also changed capacitor values in the audio stages too.  With the K2
I've tried other speakers and not found the sound that I like.  I am also a
little intimidated about any changes around the filter in the K2, since I
don't have the
spectrum displays that are recommended for exact adjustment.  Does anyone
have an idea how to get the higher audio frequencies out of the speaker?  It
will sure help me dig weak ones out of the noise.
