This kit just not worth it at any price. It is flimsy and it is very difficut to get the coil to contact the tuner. Also, it requires an antenna wire that is a lot longer than what is supplied. They want you to hold the short wire and be the antenna. Then you can't work the radio. Also, they want you to ground the kit to a water faucet by holding the end of a wire to the faucet. So, one hand to hold the ground, one hand to tune, one hand to be the antenna and one hand to hold the kit together to get the coil in contact with the tuner. So, it will get quite crowded with all of these people around this tiny kit, Junk~~~Read More
Have you ever made your own radio? A radio that needs NO ELECTRICITY; there's no need to plug it into an electric socket, no need to buy batteries for it, no need to turn a generator crank, no need for a solar panel, even. THIS IS THAT RADIO. It's as close to magic as science gets. Get one of these, put it together, and prepare to be amazed; if this doesn't amaze you, I don't know what will. You'll even learn something about radio waves, antennas, and wave propagation, if you aren't careful....Read More
