OK, I had just had a fantastic idea, which is only useful for the coolness factor. Lets take one of my local radio stations KUPD, which is trasmitted at 97.9 Mhz. Lets take an AM radio station of 800 Khz. Still can hear both just fine, lets disregard quality for a moment. The important thing here, is that even with such a range of frequency, these stations can still broadcast through things like walls with varying degrees of success. My idea is to broadcast using a REALLY high frequency. Time to leave the radio spectrum, scoot past the microwave spectrum, and its time for infrared! Which I was informed IS heat. So I'm wondering, if someone used a heat lamp for an antenna, as opposed to a long piece of wire, could you pulse infrared radiation? Sure a heat lamp won't work well because it probably can't pulse like that, at least not at a perceptible level. My reasoning is that radio waves aren't exactly perceptible either, until received, translated, and amplified. So why not make a simple crystal radio thats tuned for the infrared spectrum? I know it won't broadcast through anything, but thats not the point.
You're thoughts on this guys?
