I'd like to know how much power this station was pushing?
We have talked so much about 1710 Khz and 87.7-87.9 Mhz being illegal for use now we're starting to see this on AM? as urban legend always told folks that AM was far safer. But I wonder now that the jealous entities seem to have a hold on congress and the FCC.

It is safer but not on 1710. You just have to have less power but according to the NOUO it's not forbidden. Same as 87.5 to 87.9....only 100uV/M @ 3 meters....not even worth it unless just for yourself but not forbidden.

I never saw the logic of operating on 1710 or even 1700, in spite of better signal propagation than lower frequencies if you maintain the 3M antenna length requirement, because many MW broadcast receivers cannot receive you, and most listeners won't even think of looking for you there. |

Actually, the use of the r-f spectrum from 76 MHz to 88 MHz is not authorized for (legal) Part 15 "broadcasting" in areas subject to FCC jurisdiction.

Rich, Thanks for this handy chart. I have saved it in my FCC file as a good quick reference. It is safer but not on 1710. You just have to have less power but according to the NOUO it's not forbidden. Same as 87.5 to 87.9....only 100uV/M @ 3 meters....not even worth it unless just for yourself but not forbidden.

I stand corrected about the 87.5 to 88.1. Was mislead by the NOUO wording.
