AM Radio- Help?

Question

For AM Radio, if I was to broadcast under 300 feet(or whatever it is), can that be commercial or not? Just wondering, becuase then I may be able to find a rule breaker.

Answer 1

Your question isn't very well worded, so I'm not exactly sure what you're trying to accomplish, I do get the feeling you're trying to be a bit sneaky.

Believe me, the guys who write the rules have thought of it all (and heard most every challenge there is). You obviously have read the ruling on the situation you want to create and you don't like what you read, so now you're looking to circumvent the process. Don't even try.

Answer 2

I agree with the broken worded question being hard to figure out but here it goes.

In the US, people are allowed to maintain a station if that station is only meant to go only a few hundred feet out in total range of being heard(even though some can hit a mile) which are legal as long as the power doesn't go above 100milliwatts (most AM stations are 1,000watts or above BTW) and 50 feet of antenna (I haven't investigated it fully but heard a technical figure to get a bigger size as long as the signal doesn't go above what the FCC wants)

Anything above that requires a license from the FCC.

Answer 3

I don't think you are referring to the height of the tower, as AM is not line of sight.  

In the U.S., signal strength has nothing to do with commercial and non-commercial signals.  It has to do with the license issued from the FCC.

Sounds like you are describing a Low Power Frequency Modulation (LPFM) signal.  I that case, tower height would be a factor.  Many A and B class towers are under 300 feet.
