That would certainly put the Whole House FM Transmitter somewere around 25 to 50 Nanowatts and the SainSonic (Supposedly 500mW at High Power @ 50nW-1mW (No where near 500mW as that would cover more than a mile. So again this proves that these transmitter companies lie about power output as this graph shows it. It also shows that the Whole House FM Transmitter certainly puts out way more than 250mV per meter. Or does this show that the 150 foot rule is debunk and you can actually get 1/4 mile on a certified part 15 FM Transmitter? I’d think the latter. I’ve seen plenty of folks getting out 1/4 mile without an incedent. Now some of the frequencies people were cited for were right where NPR Radio is and I’m willing to bet Some (not all) citations were because some jerk decided because he or she didn’t find a frequency with pure static they’d transmit aneyway. Makes me wonder why they don’t come up with portable AM Certified part 15 transmitters that would cover the range people are looking for on FM. Car Radio’s have AM Stereo so that could be an alternative for car transmitters. Not trying to be a jerk just trying to understand why or how a Whole House FM Transmitter is getting out close to 1/4 mile on a ghetto blaster? On a car Radio I could see that. Now I remember in Michigan Frankinmuth where they had a Christmas light show and transmitted it on 101.3 I think. It got out about 1/4 mile from the house or stores and restaurants? This is something that interests me cuz if this is true I can certainly run certified part 15 FM and get plenty of listeners around here for my Internet station to promote it. It does shed a light on the so called 500 mW transmitter however. I didn’t think it was anywhere near that power as I had a 100mW transmitter years ago on FM and I can tell you it went 3 miles in Stereo all day long. This was when I was in high school and didn’t know about part 15. It was rated at 100mW and I had a friend with FM meters that did test it @ 100mW out. So this is why I knew the SainSonic transmitter in no way was at that power.
