OK, I feel like I have to step in. I can't stand to watch this…..
It was all humor. You need to remember that there are some very smart people here that have a huge amount of knowledge and skill. Sometimes they like to play with the noobs. Not necessarily you, but you got caught in this. There's a few individuals on this site that are really -deep- into conspiracy theories and will often ask really idiotic questions about the "Government" outlawing P25, scanners, encryption, dihydrogen mononxide, tin foil hats, and the like.
No. I can promise you, 100% the "Government" is not going to turn off scanners. There is no way for them to "turn a scanner off". You own a scanner, you can use it. Don't listen to the conspiracy theorists. They are idiots.
As for encryption, yeah, it's happening. Your scanner isn't going to decode it. If a government (state, local, federal), an agency, a private company, etc. decide to run serious encryption, you won't be able to hear them. It's -just- encryption.
No one and no government can remotely disable your scanner.
Before you do that, understand that it is a deep technical subject and it's not going to be easy to understand. It may be easy to get confused and fall into the conspiracy trap, but stop yourself before that happens.
Narrowbanding was something that happened 01 Jan, 2013 that ONLY involved changing the analog emissions on some parts of the VHF and UHF bands. It did NOT stop anyones scanner from working. It was NOT a government plot. It was just a technical change to allow more radio channels to fit in the existing space.
Take a step back, take a deep breath. Some of the above posts are humor.
