Thanks to everyone for replying. I guess I should have explained what I was intending. Between my HUGH amount of school work and my current projects, I won't be attempting this soon, but I eventually wanted to put a small B+W video camera in my RC plane. I would then transmit the signal to the ground and record on a VCR or camcorder in VCR mode. Being the sort of person I am, I wanted to turn this into a learning experience about video modulation and implement the modulator/transmitter myself instead of using a ready-made chip or module. I was only planning on doing this on a lower channel (like 3 or 4). Since I am so used to cable, I can't remember which channels broadcast in my area (I don't think there is a 4). So, I would really only be dealing with VHF, not really UHF. I also wouldn't need much power, only need to cover about 500 ft or so, and its totally in free space. I would of course have to avoid the 72 MHz RC signal Again, not something I am going to do soon. The thread just got me to thinking and I though I'd ask while the thread was going. Oh, one thing, about the DSB receivers. I had the (probably totally wrong) notion that early B+W TV sets had DSB receivers and that VSB was still used so that they would still be compatible. Am I totally wrong?
