Free Radio Forum / Re: Rangemaster - Part 15

Perhaps to clarify part 15 FM and "power levels". Part 15 FM isn't restricted by RF power output, it is limited by field strength.  250 uv at 10 meters from the antenna.

There are no restrictions on how high you can mount an FM transmitter/antenna. So yes, mount everything high up for an FM operation and you'll have great coverage.

So don't get FM confused with the power input limits that are set for part 15 AM which is 100 milliwatts into the final stage.

You could run a 20kw FM transmitter and not be in violation, just as long as you do not exceed the field strength limit. You could be your towns most powerful FM station with the smallest coverage  :lol:  :?  :shock:

A perfect part 15 AM transmitter that is FCC and Industry Canada certified for broadcasting that -wont- break the bank in these hard economic times...I recommend the transmitter at this link :


I also run a yahoo discussion group that goes into detail about LPAM and our group supports the petition that would have the FCC create an LPAM license class that is similar to LPFM.
