[Elecraft] K3 and DATA Mode Transmit Question

Did you select: MENU:MIC SEL = Line IN and set the Mic Gain
(Line In) level for four bars of ALC *AFTER* switching to AFSK A
(DATA)?

The K3/K3S Mic Gain control is overloaded (used for both mic
gain and Line In) and defaults to Mic Gain = 0 when initially
selecting data modes.
