They might be using sub audible tones to block out their communications!

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? nvm my first question, I think I need to do a WFM search on the 900 range for McDonalds because that's the only one I didn't do, so that's probably why I never heard them.- Hide quoted text - - Show quoted text - Some seem to be. I used to be able to hear my local McDonald's on my scanners, but can't anymore. I couldn't pick them up in the 900 MHZ range either, even in wide fm mode. Doing a search all the way up to the 2.4 GHZ range in am, fm, amd wide fm modes, I could no longer hear them. They're either encrypted, digital, or wired. I think only some are now, although they'll probably all eventually switch to where we can no longer hear them on regular scanners. |
