10 lbs of silver is about 145.8 troy oz. Silver is about $6.20 an oz. That makes your pile worth a respectable $903.96, less the cost to assay it, and less the margin price by your buyer. Not too shabby.
I wouldn't mind having -half- that extra folding money in my pocket.
2. Get there early and get in line behind your local used bookstore dealer who probably spent the night there.
3. By great old books at the.25 to 2 dollar range that are selling at the used book store for $4 - 15.
Don't do this unless you love sorting through old books. This is not my idea of making a living.
I actually have a small colection of books....

I actually have a small collection of books from that era. There were some fairly dangerous projects that were published in those pre-lawsuit-happy days. Spot welders, arc welders, melting down zinc and hot galvanizing your own stuff, making an air gun, making boomerangs, reloading shotgun shells...etc.
>Why does every radio emit a signal? Is it inefficiency? Is it really every radio or only old ones?
>>Your radio has a component in it (an oscillator) that vibrates at the frequency of the station you're listening to. This is "tuning" into the station. This vibration is what emits the signal.
you can squash this leak by adding a bandpass filter to your radio front end.
>Is this signal broadcasted back through your antenna or is this just a faint signal inside your radio and they have really good receivers in their billboards?
>>Definitely a result of good receivers in the billboard. Though I think the antenna helps.
yea, the RF of your radio's tuning oscillator leaks out and is radiated by your antenna. we used to detect U2 subs that way.
>>Has anybody tried to create a radio that doesn't emit this signal?
>Not that I know of. I don't think it's really been a major issue worth pursuing in the consumer market. The best way to do it would probably be to shield the box. But since you've got to have an antenna linking the oscillator with the emag signal, you can never completely isolate it.
again, a few cheap inductors and capacitors will fix this problem, it just saves the manufacture a buck or so per unit. FCC mandates spurious radiation to be below a certain level and if it meets spec. It's approved
>>Is this only something with FM radio, or also with AM?
>Both AM and FM. You've got to have an oscillator to tune into either one.
both AM, and FM, and most any receiver (radar detector detectors work the same way.) Sometimes Hams use their local oscillator to feed a frequency counter and do some simple math to figure exactly what frequency they are receiving on

Oh yea, with a lighter you can light shoe-bombs on fire
>they currently give people much grief over taking a lighter aboard a plane
Methanol is not THAT flammable, somewhere around the danger of vodka, rum, etc. I'm sure they'll amend the rules for a small quantity > 1 oz
The butane in a lighter is volatile, and could easily be vaporized and mixed in a bag or something for a small bomb.
