[Elecraft] K3S Audio buzz on transmit, especially AM

[K8TE]

The word that struck my attention is "solar" and the possibility of that
controller causing noise.  When you were connected to just the battery and
dummy load, was the battery disconnected from the solar system?  And, at
what level was the buzz relative to a full power carrier?

Every transmitter has some noise on its signal.  Specifications and FCC
rules in some cases call for a specific ratio.  I can't imagine a factory
reset solving a problem like this.  Be certain you have saved your
configuration first.  Solving issues like this is not magic, but sometimes a
mystery.
