[Elecraft] K2 keying and voltage display???

[David E. Shelton]

K2 SN 2120 is starting to get some use again after sitting around for the
last
few months. I have the SSB option only installed. I noticed tonight that my
K2's
keying is very harsh sounding that is on 40M, while listening in another
rxer.
Is there any concern I should have other than my personal taste for nice
sine
wave keying, Hi Hi. I can live with a harsh sidetone but I would like the
transmitted
signal to sound a lot better.

Also, I noticed that the voltage that comes up by pushing the DISPLAY button
is off
from the input in the back of the rig. My PS is ~13.8VDC, +/- 0.1VDC. The
displayed
voltage is 13.3VDC with the C at .18, set for maximum mileage out of my
batteries,
when I run it off batteries. What could be the problem if any here?

Thanks,
