[Elecraft] FT8 Driver Issue

[Bob McGraw K4TAX]

Go into the TX TEST mode and see if the issue still exist. If not, it’s an RFI issue. If not, back the MIC (Line gain) down to zero and start up watching the ALC  scale. The computer level may be overdriving the radio. If so back the PWR slider on WSJT down.

The K3S manual recommends setting the drive at 4 or 5 bars to avoid distortion by the ALC.. When I use the audio output slider set the drive level, the display jumps from no bars to 6 bars, and vice versa, and nothing on between.  I have also tried using the MIC level and the POWER slider in FT8 with the same results.  The software id decoding fine. Can anyon suggest what the problem might be?
