[Elecraft] Heil HC-5 & K2

[Don Wilhelm]

Bill,

That is the menu setting for setting the carrier balance potentiometer 
(SSBa=bal).  While it could work for some purposes, I for one would not 
trust it for a good evaluation of the transmitted audio.  An external 
receiver will not only give you the sound of the actual transmitted 
audio, but can also tell you that the passband of the SSB FL1 filter has 
been properly positioned for your particular voice,  and can also tell 
you if you have done the dial calibration correctly - If you hear a good 
quality received signal at the same frequency the K2 is set to, then 
both the K2 dial calibration and the position of the SSB FL1 filter 
passband is correct.  Other aspects of the transmitted could also be 
evaluated, such as tailoring the audio response of the mic and adjusting 
the compression, but it may be difficult to evaluate that while you are 
speaking due to the effects of bone conduction.  It would be best to 
record the received signal and then play it back.

I would only use the carrier balance menu parameter to make a quick 
judgement about the compression setting selected.
