[Elecraft] QSK CLICK

[Fraser Robertson]

This is a new one on me, as is the recent suggestion of increasing C72 from 
10 to 100n on the KPA100.

I get QSK clicks regardless of whether the PA is enabled or not, so I 
haven't tried the C72 mod.  I have the KAF2 audio filter, no DSP.  I have 
1M0 in parallel with R17 (3M3) to speed up the QSK.  Will the 100k /MUTE 
line mod help reduce the clicks?  Any feedback would be appreciated.

Thanks / 73 Fraser G4BJM   #4368
