I am just curious, because I understand but don't 100% understand why.
I know that some things can block radio signals but does anyone know
why this is.

If I take a local transit bus in my area, whether it is a big or a
small bus, on a walkman or scanner, their is usually little to no AM
at all. Some FM stations go haywire. Shortwave, on the bus dead. When
I go into my college, shortwave dead.

When I am in my house, I can easily get AM stations and shortwave, why
do some buildings just kill the signals?

Also, does anyone know, did McDonalds go encrypted or something with
their drive-thru? I have a Uniden BR330T scanner that includes drive-
thru ranges, and in my area of my college, there is 3 restraunts with
drive-thrus. One KFC, One McDonalds, and one Wendys, all right next to
each other. Now I have always been able to get KFC and Wendys with
usually only a search. No matter what I do, I can never seem to get
McDonalds on my scanner even trying known frequencies. I know for a
fact they use wireless headphones because when I went in to give an
order, I saw a pair behind the counter. Why is McDonalds the only
place I can never get on my scanner?


Wow what a huge loss, no mcdonalds mm mmmm, scanning is hardly even worth the
bother without knowing about all of those double cheeseburgers being sold.

That's not the fun part. The fun part is the other channels they use
for internal communications. Lets just say that some people would be
quite upset if they heard what was being said about them "off the
air".
