Your neighbors who have scanners can hear every bit of your conversation if your talking on a cell phone or a cordless phone. Cell phones have long rang and cordless only a block or two. Not to mention big brother listening in on land lines.
I would like to see the documentation to support your claim. Both my cell phone and cordless phone are encrypted.
If I recall correctly, older analog cell phones, with an older scanner that does not have the frequencies blocked (this is quite a while ago), that may be possible.
I used to be able to listen to cell phone conversations on an old TV (that went up to channel 83), but that was 21 years ago.

scanners can receive cordless phone broadcasts.they cannot and should not be able to receive modern cellular. scanners built before 1994 could be modified to unblock the cellular frequencies but could only recieve older analog signals..
"Background Information on Cellular Frequencies with Radio Scanners
Radio scanners were never built to receive cellular frequencies. However, scanners built before 1994 were able to be modified to receive these analog frequencies. The older scanner models actually had the cellular frequencies programmed in them and certain modifications allowed a user to un-hide them. Scanners built after 1994 were required to be blocked and didnt even have these frequencies hidden. They were manufactured to not even include them. Even if scanners today could receive these frequencies, they would be of almost no use. With the development and use of digital cell phone signals such as GSM, TDMA, or CDMA, and even if the scanner was tuned to their frequency, you wouldnt be able to hear anything. "

they are not legal in cars here in new york. however if you have a ham license and a transceiver that can get those frequencies your okay.
its still up in the air whether a ham license and stand alone scanner qualify because the scanner can receive ham frequencies.
nyc even requires a permit if you qualify for one.
"The New York City Administrative Code requires a $25.00 annual permit for anyone wishing to put a scanner into an automobile. There are no exceptions, although certain federal, state, or local government employees may have the fee waived - but they still need the permit. The application procedure is arduous and requires, among other things, a statement that the applicant has what the City would consider to be a legitimate need for a mobile scanner and a thorough background check. The Code also prohibits possession or use of any descrambling device that can decrpyt police communications"
its believed even in nyc hams dont need to pay the 25.00 as federal law according to prb-1 overides local laws. only requirement is that its not a seperate scanner but built into the ham tranceivers capability.

Scanners still receive many cordless phone, baby monitors, private security phones, etc. That should not be listened to.
I have a RS Pro 164 handheld. My county uses the Motorola II system. The scanner is decoding the Talk Group ID's but I swear you gotta be a NASA engineer to program this damn thing. We have one primary and 3 secondary for sheriff, police, fire etc, trouble is the primary 856.93750 is always scrambled.
I use a british naval adapter and have it hooked up to and antenna about 60 ft. in the air. It sure helps to identify what roads and neighborhoods to stay out of. Mostly illegal fires and traffic stops, 911 hangups, domestic issues. Last night a lady got stabbed with a broken beer bottle or knife at a bar, it was unclear. Funniest one yet was some guy up a ladder illegally reconnecting his cable TV.
Never a dull moment and really reveals just how many dregs there are in our society.
they shouldnt be listened to but its more ethical than law. only cellular are governed by law.

Its been a while since I have used this equipment. It was a lot more fun in the old days. But I want to point out that the Opto Scout automatically switches the Pro 2096 to the nearest frequency which I am sure that you fellows with some scanner experience know the importance of.

Encryption between the cordless phone and the base station is relatively common. Granted, DECT 6.0 has a somewhat weak algorithm, but you can get cordless phones all over the place (cheaply) that utilize this. I guess if you are willing to put enough effort into listening in, you can do it.
Another option is Frequency-Hopping Digital Spread Spectrum (FHSS). These cordless phones are also really cheap.
I am not too worried about anyone with a scanner being able to listen in.
