True, I can not hear anything over 3000 Hz so it does nothing for me, but I enjoy natural sounding audio.
For normal use, I like audio to go down to at least 100 Hz, but not be excessive in boost.
Some want the audio to sound as you would if standing in the same room with someone.
That makes no sense for DX, or QRP, or contests, but the ability to get the radio to do what you want is a plus.
If one REALLY needs to communicate, using a cell phone is a much better idea.
Its a HOBBY, no one NEEDS to communicate except in an emergency and most times a cell phone would be better.
I support every mode and every use that someone wants to use the ham bands for, as long as its legal and they don't be rude or stupid about it.
The FTDX10 looks quite good so far, the menu system is better by using the screen they way they do.
Still, I would rather have more knobs, or no knobs like the Flex/Anan radios, and no way I would buy the 10 unless they add averaging to the spectrum display.
The price is good and likely to come down.
