Normally the best response to spam is to delete it, but I thought that it
should be pointed out what kind of a con is being run here.

Now why did someone do that?

I would be quite surprised to find any cable system still using that type
of scrambling.  Most of them got rid of that system about 20 years ago
because it was so easy to bypass.


What they did was shift the carriers a little bit, and where the audio
channel was, send a jamming signal for the automatic frequency control to
lock on to.

They rely on the fact that most of their customers have no real knowledge
of their TV or have a cheap one.
I have seen some premium TV models that completely ignore the jamming
signal and some older sets can be adjusted to ignore it with the now
missing fine tuning control.

This type of widget is actually useful for removing interference from
computer equipment and near by radio/television receivers, or with TV
broadband amplifiers that tend to overload from a specific strong signal.

That widget is simply an RF notch filter.  A cheaper one can be made with
small bit of coax, a tee connector and a strong pin.  Connect the tee in
line with the cable coax, connect about 2M (for U.S. channel 2) of coax to
the end of the tee.  Adjust to remove the offending signal by using the pin
to short out the coax, starting at the far end.  When tuned, roll up the
coax into a coil and hide it behind the TV.

If you can not remove the interference completely, add a second one of
these fancy widgets.

Also be aware that homemade widgets may not get along with some of the
fancier cable systems and could cause damage to the equipment.  The cable
company may feel that they should charge for the repairs.

Do not worry about being able to answer.  Obviously anything that needs to
be marketed through spam or unsolicited phone calls is worthless.

An overwhelming response indicates a lot of sheep to fleece.  Maybe this
will remove some and give you time to concentrate on the truly hopeless.

Since you obviously know that this type of scrambler is no longer in use,
are you really giving a money back gaurantee?  Trust or believe a spammer?
