[Elecraft] K3 Crackling audio with Noise Gate running

[Matt Zilmer]

Try adjusting the noise gate level up until the crackle disappears. If
you have it set too low, it doesn't seem to close quickly enough with
high background noise levels.

I had the same problem with a cooling fan behind me at an angle. Works
fine now.  The level here is 18.  Of course, YMMV.

You can set the gate with CONFIG:TX GATE using instructions in the
owner's manual, on p59.
