	It's quite interesting that this subject
should come up. As has been said, (here) in the
bay area they have been poking around for "funny"
antennas, and harassing owners of said equiptment.

I know a couple whom this has happened to. They ,
apparently , are aiming to scare people into paying
HBO for doing something that they have every right
to do (have a VHF antenna). It's really not too
funny the kind of things they're trying to pull. 

Ok, *SUPPOSEDLY* they can tell if a person is actually
using HBO by analyzing his / her antenna. It is
my guess that they would (theoretically) use
a directional antenna, and look at the reflected
signal from said antenna..... Doesn't that seem
like a bit of a double standard? Sending
people to poke around people's backyards, and possibly
"monitoring" the signals from a person's antenna???
*THAT*'s what I call unauthorized butting in to
signals / privacy.

All that is nothing new, but as an sidenote, look
into the cordless fone issue that has been recently
discussed in fa.telecom. I think a decision was made...
"If a reasonable expection of signal privacy was
intended and implemented...... monitoring is a no-no..."
 
Well, then note this fact: near where I live
there's a transmitter link / repeater for it
of some kind. This link isn't "scrambled". The signal
from this thing (around 87Mhz...) actually cuts
*into* the bandwidth that is on low-end FM, and such.
In fact, I know of a person (I have witnessed this)
who can , with *NO* special antenna, tune his tv
to ch#6, and receive decent chroma + sound from it
with very little tweaking of any kind! (No antenna now..).
 
Surely, this isn't "Reasonable expection of privacy...."?!

Can anybody tell me what type of "scrambling", and
what freq. the main vid + sound carriers are
"supposed" to occupy? Is it usually this bad?
I mean, even el-cheapo sine-wave scrambling
techniques would seem to work better..... As I said,
I don't know how HBO actually funkys up the signal,
but would be interested to hear. I'm sure, whatever they
do, they can't be justified is this type of "antenna search".

(That they do it at all, would indicate their expection
of privacy isn't high. Do you see SHOWTIME doing that?)
