[Elecraft] K3: Mike input no longer works.

[Lew Phelps K6LMP]

What filter is set? If you have a narrowband filter installed in addition to the stock 2.7K filter, and if you have been working CW/digital modes with a narrowband filter, and if the settings somehow got messed up on the mode-by-mode filter selection, you might be trying to transmit SSB through a narrowband filter.  the K3 doesn't like that.
