Is it possible to buy a scanner?

Q. Can you buy a scanner that tunes into frequency's such as the police radios. i've herd that some can pick up cordless phones, cell phones and baby Monitors. that kind of scares me because people can listen into my conversations. i asked this question to get a general idea of just how many people have these out there.

A. Most cordless phones and cell phones can not be monitored by scanners, even if the scanner was modified to receive their frequencies. Modern cell phones and cordless phones utilize digital and/or encryption technology which can not be monitored by any scanner available to the common citizen. However, some older cordless phones can be monitored.

Do you think corded phones are better than cordless phones?
Q. Silly question but I was just wondering what you thought. Cordless phones are annoying. They have horrible quality, receive interference from just about any other device sharing the same network. Plus they need power to operate, so they are useless in a power outage. And there also in some ways a security breach. You can easily listen into a conversation with a baby monitor. And to top it off they lack most features that corded phones offer. So what's your opinion?

A. You clearly haven't used a modern cordless phone. A good digital cordless phone is unlikely to see any interference with much of anything, the link quality is indistinguishable from wired, and no, you cannot hear the call with a baby monitor. That's not to say that those things have not historically been problems, just that they're problems largely solved in pretty much all modern gear.

One good idea is to get a cordless phone system that does not collide with a home network or your microwave. Look for a 5.8GHz digital phone or a DECT (runs around 1.9MHz), rather than a 2.4GHz phone, which uses the same ISM radio band as your microwave, 802.11 network, X-Box 360, Sony PS3, Bluetooth phone, etc.

With that all said, yeah, I have a few wired phones as well as the cordless. Of course, this may also depend on how you get your phone service... if you're using POTS (plain old telephone system) phones, a corded phone is useful in a blackout. If you're on VoIP, FiOS, DSL, or Cable, there's a strong likelihood your network gear in the house goes down anyway, so the cordless phone is unlikely to be an issue.

I'm very happy with my digital 5.8GHz phones... one wired connection for a base station that supports up to eight handsets (I have four), phone to phone intercom system built-in, great range, enough to cover my house (4200ft^2) and the immediate areas outside (if I want to go for a walk in the woods AND talk on the phone, I'll use my cell).


Is it true people with scanners can hear you on a cordless phone?
Q. Someone told me that cordless phones aren't good to talk on because people with scanners can hear your private conversations. Is this true? Are there any cordless phones that are safe? What about cell phones? Can a scanner hear you on your cell phone too?

A. I will expand on the answer given by "silence.." above.

Early cordless phones used analog signals on the 49mHz band and could easily be intercepted by most scanning receivers and by some "baby monitors" that shared the same frequencies.

A little later, cordless phones came out that were on the 900mHz band but still used analog signals. A more expensive type of scanning receiver was required to listen to this band, but it could still be done.

Most newer cordless phones use digital signals and operate on much higher freqency bands. The digital signal must be "decoded" in order to be listened to and this is beyond the capabilities of the average person. While it would be possible for a highly-skilled person to intercept your call, the chances of this happening are remote.

Early cellular phones were also analog and could also be listened to using a scanning receiver, but it was much more difficult as cell signals are constantly switching between towers. You could listen to pieces of different conversations, but it was difficult to stay with any one conversation, and trying to listen to a specific person was nearly impossible.

To prevent people from listening to cell phones, Congress passed a law saying that scanning receivers had to be "blocked" so that they couldn't listen to cell frequencies. The problem with this law was that thousands of "unblocked" receivers were already in use, and that most "blocked" receivers could easily be "unblocked" by simply changing some wiring.

The good news is that, all of the newer cell phones are now digital, and like digital cordless phones, can't be listened to by the average person. There are still some analog cell phones in use (mostly in very rural areas), but effective February of 2008, these will be discontinued.

So, in the case of both the cordless phone and the cell phone, unless you are using very old equipment, you can be fairly sure that it cannot be listened to by the average person with a scanner.


when did your parents start letting you watch R rated movies?
Q. I know you have to be 17 to "legaly" be allowed to see R rated movies, but most of my friends have seen movies like the hangover, and orphan and the movie with the baby powder footprints, but i'm not allowed to. The only one i've seen is stand by me. WHen where you allowed to watch the movies? (my mum is very protective, i JUST got a cell phone on like, the 4th day of summer BTW: i'm 14)

A. My parents gave me unrestricted access to the internet..lol but they never talked about that. I guess they trust me to use my own judgement. :P

I could use the computer by myself before I could read. I'm sure they monitored me or something, but I think they mainly depended on my innocence ( and then vulnerability to feeling ashamed). It works. :l
I've never asked them if I could watch an R-rated movie. But if your mom says you can't, then at least don't let her find out if you do. This is her way of showing she cares, and in some cases it's for your own good.
