[Elecraft] Transmitted audio distortion on certain frequency

[Walter Wilson]

I have a very distorted transmit audio (listening on another receiver)
around 7.183 KC on LSB.  If I move up or down the band only 4 or 5 KC,
everything is clear again.  On USB, the problem occurs at 7.180 KC.  Any
ideas???
