[Elecraft] LIN IN level varies

[Alan Ibbetson]

I downloaded the latest K3 firmware and the fault has not reappeared in 
the past 24 hours.

Another thought struck me. The external USB sound card I use for FT8 
might be playing tricks on me. I've had it disappear from the Control 
Panel Sound menu for no apparent reason in the past. But who knows what 
Windows does under the covers.
