My point was that the power
supply was designed by engineers who didnt think about where it would
be used.


I very much doubt that -- it's much more likely they simply decided that
saving a little money was worth more than adding a little user convenience.

And if I make this thing cheap enuf, there wont be any *money* in it
for them coming out to get me.


Again, I disagree. If you make it so cheap it really catches on, sooner or
later it *will* be used in an area such that it intereferes with someone with
deep pockets and you'll get sucked into a lawsuit. If you're going to so
flagrantly ignore FCC regulations, you should simply publish *plans* for your
design so that you can't personally be convicted of selling non-type-accepted
equipment... unless you do want to have bars for windows for some time. :-)

Back when we used CB radios to talk to each other, we bitched to the
FCC about jerks in urban areas putting *1000* watts on a CB channel.
Where was the FCC then? No, man, out here, we are off the radar map.


The FCC does still routinely bust retailers for selling CB band linear
amplifiers and rigs that can transmit outside the CB frequencies.

I still think your best bet it to use 2.4GHz WiFi gear linked "house to house"
with cheap dish antennas on towers. Get that amateur radio license and you
can legally run enough power that you'll easily make the distances, and no one
will question why it is you're buying, e.g., 10W 2.4GHz amplifiers. Those
dish antennas are probably going to be a lot cheaper than a bunch of Yagis
anyway...

The FCC allows 4 watts EIRP for fixed point to point WiFi links. At 2.4gHz
this is a lot of power, usually created by focusing the output of a
regular router or similar device with a small dish or Yagi.

For example, the well publicised "Pringles Can" antenna can be easily
modified to put out that much from a 100mw source. You need line of site,
but if you figure a two routers, antennas, wires, etc can be purchased in the
U.S. for less than $200, you can set up a whole relay system.

The latency will be much too high for VoIP and video conferencing, but
websurfing and file downloading would be fine.

Even if its cheap, it aint *easy*. a 180 mhz Yagi on a 30 foot pole
compared to the soup can users would take to in shorter range high
density regions where they need more channels.

But in any case, whether you all know the technical issues or not, I'm
not going to get that feedback here, so I'll quit bothering you.
My address is 1984 Kirkendoll rd, Clinton AR, 72031. you have my email
addy. send it to the FCC for all I care. That's how much I think they
will give **** what goes on out here. Besides, there is a whole world
out there of remote areas that are not served well beyond the reach,
whatever that is, of the FCC or their ass kissing agenda to big media.
It this takes off, by the time the FCC figures it out, it'll be like
trying to get CB users to register. snurk

That doesn't appear to be nearly so much in the "boonies" as I would have
thought. As the crow flies you're only something like 5 miles from I-65,
right? I'd predict that within a decade you'll be able to come up with some
reasonably high-speed, reasonably cheap solution based on the cell service
providers rolling out high-speed data services along the interstate there, if
you don't already have the option of getting a cable modem or DSL just as soon
if you're willing to pay for the cable back to highway 16.
