Thought you might like to have this info on hand:
Any type of transmission (other than Intermittent
Control Signals and Periodic Transmissions) with
a bandwidth less than or equal to 200 kHz, is
limited to 250 uV/m @ 3 m. FCC Section 15.239
My words: Most hobbiest/amatuers and probably
verterans in the field tend to measure outputs of
a transmitting device in power (watt meter). As long as I have been experimenting with transmitters, LPFM (which does not necessarily
not include of forms of transmission) should
not exceed 10 mW's of power ( which is probably
the closest one can get to the above FFC guidelines), as far as not having
to have a license.
This was nice of you to say to all who may not
know where the line is drawn. Thank you...
