Of course they will, if you stay under the wattage limit, which IIRC is 250 milliwats. I built a legal 250mW transmitter years ago and ran a powerline radio station in my college dorm. Two capacitors coupled it to the power mains, and it transmitted to the whole building (250 residents) with ease. I could get the signal on a pocket radio for a couple of blocks. It was sweet until I tried to boost the power a little and fried it. I had a roomate who was a quiet, withdrawn, rumpled and shy geek, but hand him a mike and he became EMCEE KOVAR. I had enough stereo equipment to set him up with a simple mixer, two turntables and a tape deck, and that boy could rock the mike. It was great fun. Good thing for my vinyl collection that nobody had heard of scratching yet. Often you will see For Sale signs in front of houses, with a note that says "Tune your radio to XYZ to hear more" these are 250mW transmitters with a tape loop, unlicensed I believe. Harold Hallikanen will pipe in soon enough and straighten us all out on the FCC rules about this. -Lawrence -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
