Before you do anything drastic like looking for another radio, can I ask a
silly question or 2?
If the output power is flat across the AF spectrum when using ssb mode, why
doesn't everyone use it rather than DATA-A?

Well the main reason as I said in my post that I sent about the same time you were writing yours is that it is a hassle changing all the EQ, switching the input from MIC to LINE IN and remembering to turn off the compression. Of course some people may work digi all the time and never use a mic, in which case it would be the most sensible option. But I don't want to go through all that when I hear someone on SSB that I would like to call. Plus, many programs know what mode the K3 is in and won't do data if SSB is selected.

And since the output power is apparently so poorly controlled in DATA-A,
(with much higher power than called for) doesn't this actually give higher
rather than lower IMD?

Yes, although as long as the power is below 100W the IMD should still be within acceptable limits.
