K3 Error 6 when changing filters then xmitting

This is easily repeatable on CW.

I have the 2.8 in slot 4 and a 400 hz filter in slot 2.

If I turn the bw down into the 400hz slot 2 position and Xmit. The amp
will fault out with an error 6.

I noticed this in the RTTY contest too but never figured it out.

I wonder if I should try a transmit recalibrate? I just upgraded the FW
on my K3, P3, KAT500 and KPA500 to the latest.

Sorry about the mixup.

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

In reply to this post by w0mu

I completed the TX calibration but the problem persists with a dummy
load or antenna.

I can see a huge power spike after changing the filters which is causing
the amp to fault out.

I noticed that the power output of the amp ramps up initially.

Weird.
