Zonekeeper posted:Assuming I wasn't listening to a simulcast, this could be the explanation! This happened when I was like 5, so I'm probably forgetting most of the details - the part that sticks out was the same audio coming out of my clock radio and TV at once. I can't find a cite, but I remember reading that the reason broadcast TV started at channel 3 back in the day is because the lower end overlaps with police/taxi 2-way radio bands. Similarly, FM transmitters for MP3 players (to use your iPod without a tape deck or aux in, were big a from the late '90s up until a few years ago when new cars started coming with USB or at least 3.5mm input jacks) and some wireless headsets step on the bottom end of the FM band. I'll be listening to NPR and pass an older car or pull up to the McDonald's window, and it'll go to static. Edit: AM radio is 153kHz-26Mhz, FM is 88-108MHz, two-way radios and TV channels 1-6 are in between (CB, for example, is around 27MHz), and TV channels 7 and above are above FM. So TV channels 6 and 7 could be picked up at the ends of an FM dial if they overstepped their bandwidth or your radio had some slop in the tuner. Wikipedia has charts if you want specifics.

Channel 2 is very much a station. Channel 1 was until 1948. Early Television Museum, which has a lot of interesting stuff, includes this Andrea set that tunes channel one: Unfortunately, digital conversion means you can no longer rig up a late 1930s television to fully work.

So what I'm thinking is: make an ATSC-to-RF modulator that outputs on channels 2-13 simultaneously instead of just channels 3/4, and which lets you map each RF channel to a specific ATSC channel. Leave one RF channel as a general pass-through for the ATSC tuner so you can select digital channels that aren't already mapped to RF, program the other channels, etc. Now your old Philco Predicta works just like a normal TV again!

Hey DicktheCat: Since you don't have PMs, I'll post here. That looks to be a French Chauchat, which is a full auto machine gun. If you don't have NFA paperwork for it (and since you said it was found in a ditch, I'm guessing you don't, but I could be wrong), or if it's not deactivated to the ATF's satisfaction, you may not want to post pics of it online, since owning it is a pretty major felony. I'm not remotely an expert on the legal technicalities around full-auto weapons, so if you want more info, poke around the NFA or Military Surplus threads in TFR. Zedsdeadbaby posted:You should probably hand it to the police immediately. You're looking at prison time just by hanging onto it there buddy. Also, reading back, I see I'm not the first to mention it. DicktheCat posted:Even if it's not functional? Because this thing will NOT fire. At all.

Found this link via TFR. . One thing I"ll add is that you need to make a major effort to find out if it's registered, not just asking around with grandma or whatnot. One that was registered back in the day, even if you don't have the paperwork, is worth tens of thousands of dollars. One that's not registered is a felony. Properly deactivated into a parts kit (ATF instructions are easy to find and it just requires a sympathetic friend with a welding torch) you're still looking at a few thousand bucks. Handing it to the police it's still a potential felony and no money at all. Hell, non-zero chance of bad lawyer bills on top of that. All in all, I'd say ask around in TFR. You can get some good advice on who to contact to find out if it was ever registered.

I get that it is technically an assault weapon, but would law enforcement really care? The only person that thing would kill is a person dumb enough to try to fire it.

Germstore posted:I get that it is technically an assault weapon, but would law enforcement really care? The only person that thing would kill is a person dumb enough to try to fire it. It is not "technically an assault weapon." The Chauchat is legally defined by the 1934 National Firearms Act as a machine gun, and as such, it is required to be registered with the Bureau of Alcohol, Tobacco, Firearms, and Explosives for any private citizen of the United States of America to possess. What DicktheCat's local law enforcement knows or cares is immaterial, as is the machine gun's current lethality. It is federal law.

It pains me to say this but you really should just cut that into a bunch of small pieces with a cutting torch or hack saw and dump it into a lake. Whatever you do make sure it's permanently taken care of (IE don't throw it into another ditch so that someone else can find it). e: assuming it's not registered. For the love of god please check if it's registered. If it is that is an awesome piece of history you can restore and keep!

You guys are all paranoid and acting like the big mean government is just looking to nail anyone at the drop of a hat. Call your local police department and explain that you found your grampa's rusty old gun and ask what steps you need to take to deactivate it and/or get it legally registered. They're not going to bite your head off for calling and explaining the situation. Worst case they'll ask you to turn it in. Collateral Damage has a new favorite as of 12:23 on Oct 4, 2013 |

You won't definitely get arrested/prosecuted if you show up at your local police station and say that you just found out that you're committing a felony by possessing an unregistered machine gun. But you won't definitely NOT get arrested/prosecuted either. Think about it like this. If you and grandpa found a nicely-wrapped kilo of coke that got dumped in a ditch, then picked it up, brought it home, kept it for a while, and posted pictures of it online, would you be comfortable just walking into a police station to turn it in with it with no lawyer?
