I second this suggestion. I personally did not like the extra bass in my
audio. I have compensated for this using the TX EQ. But as you say, doing
that is less than ideal for data modes.

I also find, apart from the excessive FM deviation that I mentioned before,
that the FM sounds a bit "thin" compared to SSB. I'm wondering if the FM
audio needs a bit more de-emphasis. If it's just a matter of personal
preference, then I can't use TX EQ to adjust it to my liking as long as
there is only one TX EQ setting for all modes.
