If the K3 were supplied with a stock microphone, rather than leaving it to
the purchaser to potentially make a poor choice and then not bother to
compensate with the equaliser, I believe we wouldn't be reading these
admittedly isolated comments about K3s with "thin audio". This has
recently come up again with the current dxpedition in Iran.
I probably make fewer than a dozen SSB QSOs in a year,
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.
