This is the device I'm referring to:http://www.bhphotovideo.com/c/product/474795-REG/Impact_AVT12_AVT_12_Wireless_Audio_Video_Transmitter.html
I also mentioned it in an earlier post asking about FCC part 15 rules. And now I've got some more questions. In the FCC part 15 rules for unlicensed TV transmitters it is allowed 512-608 MHz and 614-698 MHz according to the part 15 rules as I found on http://edocket.access.gpo.gov/cfr_2010/octqtr/47cfr15.707.htm
However that AVT-12 works on channels up to 54 which according to http://www.csgnetwork.com/tvfreqtable.html
is a channel that ocupies the frequencies 710-716MHz. Now I'm not sure if the FCC regulations allow that or not, as I can't find any mention of frequencies that high in the part 15 rules. Is the page I'm using as a part 15 reference an old page, and since then the FCC widened the available frequencies for unlicensed TV broadcast use? I mean it is limited to 25 feet range, but does that limit make it legal? Or is it still illegal, but the limited range just makes it very unlikely that the FCC will discover the illegal transmission, and thus the company selling the device is trying to help people get away with violating the FCC's rules? Please let me know, thanks.
