Discovered a way to monitor and listen in to 3G and 4g calls

[Hugo Drax]

Just go to your local movie theater. No fancy equipment needed.

:biggrin:

What does 3G and 4G have to do with calls?
How do you hear both sides of conversation?

Get a job with US law enforcement and you can listen to all the phone calls you want, 100% warrant free thanks to Stingray.

Dude the first rule of stingray is we don't talk about stingray!

Ah, fond memories, back in the late '80's, early '90's cordless phones were all listenable via a scanner. We lived in an Apt complex so 8-10 people were always in range. Weather they were fucking, fighting, or just ordering pizza or phone-sex we could hear it all. One couple (Victor and Patty) were great, Patty would call Victor and complain about how painful his anal session was from last night. Then she would tell her friends about her nasty vaginal discharge and how she thinks Victor gave her the clap. It was better than any TV show!...

I used to live in an apartment complex on a street full of them back when I was a newspaper photographer. I'd monitor fire and police on the scanner for work, and would occasionally scan the cordless phones too.

One day I heard a panicked woman calling 911 because she was pregnant, stuck on the toilet, bleeding heavily and thought she might be losing her baby. Sad, sad, sad. I hope it wasn't Patty.

Once bill C-51 passes you'll be able to do this here too. :awe:

Back around 1997, I walked into Radio Shack and watched the guy behind the counter running a scanner listening to random cell phone calls. So I thought, what the heck, spent $200 on a handheld scanner and a book of frequencies to pick up local fire and police transmissions.

It had a scan mode so you would get about 30 seconds to a few minutes of conversation as most people went between towers. Most conversations were mundane, but others were not. It was interesting.

About a year later ATT & Sprint started to upgrade to digital encrypted frequencies that you could not intercept.

Sold the scanner on Ebay for $150 in 2012.

Yea, we could get cell calls too but only one side of the conversation as the cell was usually talking to a landline.

Don't most calls still use "2G" CDMA in North America?

Back in those days, you didn't even need special equipment to listen in to analogue phone calls. AMPS (Advanced Mobile Phone System) ran between 824-894mhz. Which just happens to be the same frequency band as UHF TV channels 73 to 83. If you played around with the fine tuning knob on older TVs, you could hear people's conversations. I discovered this completely by accident. Had an old portable TV in my bedroom in my early teens, and stumbled upon this trying to see what stations I could get on it.

Old baby monitors had the same problem.

We're talking a long time ago when cell and cordless phones had not converted into digital, with a scanner you could hear almost anything, one would set it to "sweep" a band and it would stop when it caught a signal.

Lot of them do but any new phone is HSPA. I don't know about all telcos but one I work for is actually going to be shutting down CDMA soon. OnStar uses it though, so I don't know what's going to happen to that.
