Not op, but fun story to share.

The year was 1999, I had befriended a strange group of friends from an IRC support channel. We all lived within 250 miles of each other and one day decided to have a gathering with about 6-7 randoms from the channel. Hilarity ensued as we played games of command and conquer, Starcraft, and Serious Sam. I was yelled at for saturating the 1.5mbps SDSL line with my webcam, streaming views to our friends who were too far to drive in. Someone else was eating aluminum soda cans. At one point one guy happened to login and said “wait you guys are having a LAN party? I’ll hop on the PATH and be right there”. Then my life changed in front of my eyes.

In walks this dude that looked like he came straight out of Hackers. We all dap up and continue talking about random nerd things. The conversation goes to cell phones and how the fcc passed this law which OP talks about. Surprise someone has a grandfathered scanner that could scan 800-900mhz. Dude that showed up starts talking about how he knows a guy that knows a guy that took his code and runs an elaborate carding net. Dude then whips out a demodulator app that he wrote that takes beeper signals from the scanner audio and decodes it to text. He tells us we can pull livery and taxi beeper codes because they text headquarters with the credit card numbers on pickups. Then his app does it. One guy holding the scanner at an angle to one of those bend/squiggly microphones that were ubiquitous in the AOL era. Modem like beeping screeching through the air. Then messages and credit card numbers start streaming through this dudes app. The entire room does a collective holy s#%^ mainly because we can’t believe this would be streaming in “broad daylight” across the Hudson.

He went on to explain how he got into hacking almost just like in the movie Hackers. Dude was brilliant and got recruited into hacking groups as a programmer when he was 13. He was writing stuff like this for 5 years. We think we had crossed paths at some point because I was deep in the demo scene and wrote patches for hacking groups.. but that day blew my mind about how security through obscurity worked and led me down a black hat path that switched to white hat in the early 2000s

I once overheard a phone interview for a position so interesting that I wanted to apply for it myself.

The answer to "How did you hear about our company?" would not have gone well. :-)

When analog TV's with UHF were still a thing, I could rotate the UHF dial all the way to the top of the band and just begin to hear the unencrypted analog cell phones. Crazy.

Lots of similar stuff in the book The Best of 2600

Back when i was in high school in the late 90s/early 2000s there was a website, i think called cellphonescanner (.) com that had a realmedia stream to listen to analog cell conversations around NYC and Toronto or something like that. It was great entertainment.

One of my friends who was a huge scanner fan (did you know they had their own magazine?) worked in a boring mundane part of his family's business. Most of his day was spent waiting around for two or three loads of paperwork to come in to be filed. It was a make-work type of job to keep him employed and out of trouble. What he did most of his day was listen to the scanner. Mostly police and fire calls but he did modify the scanner to pick up cell calls. Most were short but there was a two hour long call that the radio tuned to one day I was visiting. Given the price of cell calls in the mid 90s, especially during daytime, this was highly unusual.

The call was a professor at the local state university talking to a woman whose identity I was not able to determine. Almost the entire conversation was about how much he hated Palestinians. That they were subhuman and should be wiped out. I grew up in the South and had heard hateful things before but this was the first time I heard someone advocate for genocide so openly. That conversation has stuck with me ever since, making me wonder what's going on in people's minds that they keep hidden from the public.

At one point in the conversation the woman asked if he was on a cell phone and if anyone could overhear them. Despite there being no way of them knowing we were listening, it still caused my hair to stand on end. He said it was unlikely. The quality of the signal didn't waver during the call and was strong the entire time was he probably was stationary nearby. So very odd that he didn't call using a landline given the cost of such a cell call.

Honestly I never heard anything interesting on either analog cell phones or cordless phones. Messing with drive-thru intercoms with our modified Icom W2-As was a hell of a lot more fun.
