[Elecraft] K3 line out

[Rick Prather]

Jim,

A shot in the dark here but, is it possible you have line out set to "Phones" ?

"Note: Normally, LIN OUT sets a fixed-level receive-only output for main/sub (L/R), compatible with digital modes. Tapping    switches LIN OUT to =PHONES, where the line outputs match headphone audio, audio level is controlled by AF/SUB gain controls, and both RX and TX audio are available."
