Human society DEPENDS on limitations on other peoples activity. To name only a
few simple ones, we have traffic lights, speed limits, lane changing rules, and
parking rules. If I play loud music I'll disturb my neighbors. There are
hundreds of other ways that we as human beings must be considerate of our
neighbors. Most of these include limits on someone's behavior.

One roundtable of a half dozen guys on ESSB transmitting as described in a
previous email can easily chew up 25 kHz of a band, and in extreme cases, twice
that.

I have no problem ESSB or similar modes on an empty band. But propagation,
lousy receivers, a big power amp, and local noise can turn one guy's hot DX
band into another's dead band.

I've been working the CQWWRTTY contest this weekend. That is burning about 40
kHz on 80M (3560-3600), less than 75 kHz on 40M, and about 100 kHz on 20M
(14050-14150). There are probably more than 1,000 active stations worldwide
sharing that bandwidth, and this isn't a BIG contest -- the big contests have
5-10 times that number. That's just over 200 kHz divided between more than
1,000 guys, and it's 20 times less piggish than those six guys in an ESSB
roundtable! These contests prohibit activity on 160M, 30M, 17M, and 12M, and it
is few contests burn more than one-third of a band.
Compare this with "normal" activity. A few days ago, I wanted to check out a
new 40M dipole I'd put up for contesting. It was 3pm on a weekday in CA, and I
heard one one CW or digital signal (a guy in Detroit, more than 2,000 miles
away), and only two SSB QSOs. And my QTH is quiet, in a redwood forest with few
neighbors!
