[Elecraft] bad audio at K4XU

Hi Dick, 


I had the same problem when my power supply voltage was too low 
(12 volts with no load).

Okay, I need to be more specific about my "bad audio".. The audio is raspy, 
like it has rf in it. It is independent of frequency, power, mic type, 
recorded or not, Hi or Lo mic gain setting, and mic drive level. 

The only other issue I have is that the low power carrier is 5W when the 
PWR is set at 12W and jumps to 15W when PWR is set to 13W. It is 100W at 
the 100W setting. 

Perhaps the two issues are related. CW operation is unaffected.
