[Elecraft] K3 Error 6 when changing filters then xmitting

[Michael Eberle]

Fault #6 appears to be 'Excessive Driving Power' so it probably wouldn't 
hurt to run the TX Gain Calibration again, make sure PWR SET in the menu 
is set for Per Band, then check the power settings with the KPA500 on 
each band in operate mode.

Although I'm not sure why it would only do it when the 400Hz filter is 
selected.  You might double check that the 2.8KHz filter is still set as 
the TX filter for SSB, CW, and DATA
