  Subject: [Elecraft] K3 MH2 Mic Problem


  My K3 has an internal 2M module which is working very well.  However since
  installing the 2M module some two weeks ago I have a mic/power problem on
  the HF bands.

  When keying the mic on 2M I see a 10 W reading on the power barograph and
  the power reading in the VFO B area is 1.01 Mw which is what I would expect.
  Switching to a HF band and keying the mic I see one bar on the power
  barograph and 60 W in the VFO B area which is my power setting.  To generate
  power out - more than one bar - I need to hold the mic almost in my mouth
  and at an angle so the top of the mic is nearer to my lips. However
  generating power out is inconsistent. 
  Mic gain is about 56, compression is 5, MIC SEL is FP.L BIAS.  I have the TX
  EQ set to reduce the base and slightly increase the treble frequencies.

  What is wrong?  Appreciate any ideas.
