[Elecraft] K2 and KX3 with A/B switch

[Don Wilhelm]

Graziano,

How are you measuring the power output in SSB?  If an external 
wattmeter, you are likely driving it to full PEP power.

I test the SSB operation on each K2 I repair to be certain the PEP is 
the same as the CW response at full power.  I use an oscilloscope to 
determine that.  An external wattmeter will only show about 50 to 60% of 
the full PEP.

Run the SSB C menu parameter to 3:1 and try it.  If you are using an 
electret microphone (Elecraft or Icom), the SSB A parameter at 1 should 
be sufficient, but if using a dynamic microphone, a setting of 2 is good 
for the higher output microphones but 3 may be needed for those with low 
output.

73,
