Stuart,
I certainly agree with you, all except for the words "optimum" and
"proved". I have this vision that the Bell Labs folk who defined those
limits were male folk with more grey hair than I have! 300-3000 is
perfect for both their transmission and reception, but put a 7 year old
granddaughter on the line and you will quickly decide they might have
looked a bit wider!
OTOH for us old(ish) mostly male hams (who aren't allowed to play the
flute on the air, anyhow) it is perfect!
