Found this in a local thrift store. Sounds ok for satellite audio that's heavily compressed.... Sub woofer helps a bit.
It's almost cool, I'd love to watch some of the tech guys hack the signal and broadcast their own multi-channel network.
That would be interesting, these things are up in the 2.3 GHz band. Way back when the earth was cooling a buddy of mine built a pair of 2 way radios out of Fuzzbuster antennas. Short range line of sight but rather interesting and probably inadvertently the first radar scramblers.... I always wondered about old cell phones, I have a pair of the old Radio Shack 5w 'lunch pails' with long dead battery packs and car kits. Considering todays phones are rated in milliwatts 5w would be rather interesting.
Brings back memories of some of my ultra-smart neighbors, they talked about two encyclopedia sets above me but I love hearing about their contraptions including sending power over the air. They claimed they built a device that could power anything normally plugged in, remotely, or not physically plugged in. I never saw the over the air power supply but these guys weren't known for kidding around. We were lucky, we had a real electronics supply store in town, aisles of parts, metal boxes and electronic components to build anything, unfortunately it's long gone.
Tesla was experimenting with over the air power. Seem to recall that there is a lot of line loss from those big overhead transmission lines..... We have smaller scale versions now with those inductive charging devices for our cell phones. When I was a teenager I lived in Radio Shack stores! Anytime I was on the road in the states I would always visit every Radio Shack I could find, used to go down to Rochester NY to George Eastman house quite regularly to check out their museum/photography exhibits and while there they had a pretty decent surplus parts store in another part of town. Up here we had Electronic which was more warehouse/wholesale but had a catalog as thick as a phone book and they carried every conceivable component you could image, but they are gone I think. Also had Active Surplus which was bigger than A1 but not as jam packed.... now we only have the one. And Radio Shack closed down in Canada and was replaced by The Source which was a mere shadow of Radio Shack. They are now shutting down those stores as well. I hunt for stuff on eBay but it's not the same, although as I think of it perhaps it's better in many ways as I always seem to have picked up a lot of things I wasn't looking for when I used to frequent the surplus shops. Was talking to someone about parts the other day and they mentioned that some company in China had bought up a lot of the supplies of parts from major manufacturers and that's why we can only find some parts there. The flip side of the equation is we are such a disposable society today that instead of repairing something we toss it away and as a result there are very few places that repair things and the parts to do the repair are not easy to find. We ran into this the other day looking for a top cover for a Samsung fridge so the door hinges could be moved from the right side to left. The little plastic part is $14 but has to come from China as there are none of these pieces anywhere in Canada. Granted I would have suspected the fridge probably shipped with both covers when new but of course someone tossed it out....
