Let's crunch some numbers: Our total MF/HF spectrum consists of just
3.75 MHz, with only about half of it, 1875 kHz, useful for
communications at any one particular time of the day. If suddenly,
as if by magic, all licensees were granted MF/HF privileges, we could
possibly have 670,000 hams attempting to fill that 1.875 MHz.


Watch this closely, boys and girls. We're about to be given a demonstration of
"figures don't lie, but liars figure". In this case the person "figuring" is no
less than a self-proclaimed university "math lecturer", so we're seeing a pro at
work!

Okay, I'll grant you that folks have to work and sleep, so let's
say at any one time, we have one-fourth of all 670 kilohams
on the air, with two per QSO.

One-fourth? That averages out to 6 hours of hamming every day by every ham, or
167,500 US hams on the air at any given instant, 24/7.

Uh huh!

Get real!

The most popular US operating event is the ARRL Field Day. To date, the record
number of logs submitted was 2261 in 2004. The average number of
transmitters-per-log was 2.41. That works out to 2,725 two-way QSO's on the air
at any time. The mix of phone vs CW runs about 60:40. That works out to 1090
CW transmitters and 1635 phone transmitters active at any moment.

Presuming a phone transmitter uses 2400Hz of spectrum and a CW transmitter uses
200Hz, and assuming your 3:1 geographical sharing, that works out to 1.38MHz of
the avaliable 3.75MHz is "busy" at any given QTH, leaving 2.45MHz available for
additional users, and that's on the busiest MF/HF weekend of the year!

So much for your 336 Hz per user!

He also forgot to discount the time spent by hams typing in newsgroups
instead of working their stations.
