There are a number of ICOM (R3 and R10 plus others), AOR, and Uniden radios that were made for overseas that do not have the 824 to 850 and 869 to 894 ranges blocked. Older radio Shack scanners, like the Pro-43, can be modified to receive these frequencies but it will not do the user any good since for the most part, cellular traffic is now digital and not decode able.

I don't know why some of you are even in the hobby. "Dull and boring" ??? I guess you don't do your homework. I am busier than ever with all of the new federal homeland security, ICE, CBP, military, trunked systems, digital voice decoding (DSD), snooping military air freq's. I can go to my shack any day of the week and pick up federal surveillance going on. I can't even keep up with it all. We have the greatest hobby in the world !

You sound very ignorant when you say something is "impossible". It is illegal, so you shouldn't pursue it. I used to listen when it WAS legal. Trust me, it's a little intriguing, but it's not ALL THAT. If you like listening to dysfunctional people get on, just watch cops on TV. It's the same thing. It doesn't really belong in our hobby.

But to the guys saying it's "impossible", you are pretty ignorant, just like those who said our hobby was coming to an end 12 years ago because of APCO 25. I told them that was a joke. Now we can decode P25 with a cheap computer and sound-card ! You are not even close to being qualified to say what is impossible !

No not impossible, but out of the technical/financial range for many. Breaking GSM Security With a $15 Phone

Okay I know it says $15.00 phone, but I'm sure it takes more than that.

Back in the day (early 80s), I didn't listen that much to cordless phones, but every now and then, I would get the "itch" to tune in. I heard two minority women talking about how to get a job for the post office and who to talk to. I guess one needed an "inside connection" to get that job. I also heard some pretty kinky stuff about secret romantic get togethers. Again, that was then and this is now. I was 16 then and have grown. The best you can do now is go with the 900mhz, non-digital cordless phones, if avaliable.

Wireless home phones like the 5.8 and the 6.0 ones can be wide open. I had a pro2030 with a easy mod done to hit. It gets almost all of the 900 wireless freqs.The problem is they are a bit off freq. By mistake I got a pair of Sennheiser wireless head phones with a freq tuner on them in the 926.929 range.

The signal from a few neighbors came in super clear. I was shocked to hear at what I heard.

If i had a Vfo on the pro2030 ? It would do the same I think

900 MHz Analog Cordless Phone

There's still a lot of old 900 MHz analog home cordless phones in my neighborhood. Although I never listen to them using my PSR-600, I do hear them occasionally when they break thru one of the channels I have programmed into my 900 MHz Motorola Maxtrac I use for 33cm operation. The calling channel (927.500 MHz) seems to have a lot of activity where I live.

I was minding my own business one evening when a girl two doors away suddenly came across that "channel". It was around 1am and she was talking to her boyfriend and needless to say she was a little . . . uh . . . anxious, needy, or whatever you want to call it. That was the FUNNIEST stuff I'd heard in a LONG time with all the carrying on that went on in that conversation - or rather - session.

Years ago when I lived in Tallahassee there was a young woman (mid 20's) who operated her own "escort" company from her home. I would listen using my Radio Shack PRO-2006 to her analog 900 MHz traffic and would hear her calling her *girls* to arrange for motel encounters for the guys who would first call her home/business number to get prices and/or arrangements.

Yep, there USED to be plenty of interesting stuff to listen to other than fire, medical, police or whatever. Nowadays the illegal stuff is either encrypted, Spread-Spectrum or whatever. In either case, it's beyond what most radio gear that's available to *us* is capable of listening to.

If you want to listen to cordless phones, maybe, cell phones no. I am no expert but, with the newer technology that has the entire band as one big signal not individual channels as in the old analog days. Hacking a cell phone may be the way, but you would have to know what signal you want to listen to, there is QAM 16 to QAM 64 or more( look that up in you Funk and Wangles) . Depends on the system and location rural or city as to what type of system is used. In the EU, I have read in some blogs that the basic encryption has been broken, not because it's weak, but because the cell companies there use a weak key all 111111111. I tend to use my cell phone as opposed to a land line now a days because it is so secure. A good indication as to how secure cell phones are, that with a warrant the police get a feed from the land line component of the cell system not over the radio portion.
