This is most interesting. I have heard of the "Eyebank Net Docket" and the
fact that it prohibited communications even for non-profit organizations,
but is it really true that there was no prohibition at all on business
communications in the amateur service prior to 1972? I'm embarassed to admit
that I don't know the answer to this, since I was first licensed a year
earlier (1971).
Consider the following points:
1. The motivation for banning most international third party traffic was to
protect lucrative European government telephone monopolies.
2. If I understand the ARRL correctly, the US amateur service got along just
fine without any prohibition on business communications until as recently as
1972.
3. In 1972, the very same year the strict prohibition on domestic US
business communication over amateur radio was imposed, the Bell System
launched an all-out war against competition in all forms (e.g., MCI et al).
(See the book "The Deal of the Century", by Steven Coll.)
One wonders if the timing of these last two events was a coincidence. Given
that the anti-competition war ended in surrender by the Bell System, perhaps
it's time that this rule (and the reasoning behind it) were re-examined.
With the high speed digital networks now under development, the rules for
message-by-message approval by an amateur operator of all third party
traffic are becoming even more impractical.
For example, it is entirely possible, technically speaking, to take a couple
of N6GN's megabit microwave transceivers, attach some codecs and digital
multiplexors, and have a portable 100-line trunked telephone system that
could be set up for free public use in a disaster shelter. But to operate
legally, such a system would have to have 100 amateurs on hand, one to
monitor each voice channel to make sure no improper communications were
passed! Ridiculous.
The potential for this technology to provide a "voluntary noncommercial
communications service" to the public is severely stunted by these rules.
The likely result will be a service that is even more irrelevant to the
modern world and unable to defend its shrinking allocations. (The microwave
bands are almost certainly next, by the way.)
It has always seemed to me that any abuses of the amateur service by
commercial interests would be automatically self-limiting as long as you
enforce the basic characteristic of a radio amateur that is inherent in the
word "amateur" -- that he receives no pay for his services. Human nature
being what it is, there aren't many people who will gladly volunteer their
time and facilities to make money for somebody else when they can't get a
share of it. I would think this would be *especially* true for hams.

Why do you think that the monitoring stuff should be in rec.radio.shortwave?
There are those who do one or the other and don't want anything to do with
the one they weren't interested in. By the NAME of the group, shortwave
listening goes there, but monitoring is still left out in the cold, and most
people still expect it to be HERE. So until someone gets off their other
end and sets up rec.radio.monitor I will continue to expect it to be here.

Message-ID: <311@ssc.UUCP>
WB9MVP asked for info on FCC rules regarding RFI susceptability and
telephones.
Unfortunately, there aren't any. In fact, the FCC doesn't even require
telephones to FUNCTION in order to be registered! All that FCC registration
requires is that they not generate any signals that would "harm the
network".
The big RFI problem with the el-cheapo and many electronic phones is
that they have the entire telephone on an IC, which is line-powered
by a zener diode in series with the line! Of course, the line makes
a dandy antenna. The diode makes a nice detector.
When my neighbor's $12.99 Radio Shack phone picked up my SSB on 20 mtrs
(for some reason their line was running across MY backyard to the
pole!), Radio Shack told them I needed to get a "filter" for my
transmitter!
As if harmonics were causing the problem....

Subject: the FASO of Burkina
I read the answer to the question where Burkina Faso is. Please note that
the country's name is, according to National Geographic Magazine, Burkina.
The term FASO means something like 'peoples democratic republic'.

While it would add a little expense to cellular phones to be encrypted,
perhaps a more realistic reason than the ECPA was passed, even though
even THEY might have believed it to be unconstitutional, was that it would
get cellular systems popular to begin with. Later, when the law is overturned
"they" will come out with "Cellular II" which is encrypted and highly secure.
Now they have the market developed, and forcing a massive product turnover.
But then, we will get all the junked 800 Mhz hardware :-)
