Those complaining about "thin audio" clearly don't know much about the 
fundamentals of communications and speech intelligibility. It has been 
well known for nearly a century that the frequency range that is most 
important for speech intelligibility is 400 Hz to 4 kHz. It is also well 
known that speech below 400 Hz wastes transmitter power.  Those guys in 
Iran SHOULD have "thin audio." I'd consider them incompetent if they did 
not.

Ham radio is communications, not broadcasting.  Many of us have done 
both, and we know the difference.  I'm a Fellow of the Audio Engineering 
Society. My music recordings are full range. My ham transmissions are not.
