Hey, Roy -

My 3 mW answer was for 30 meters. I think that ratios correctly to your
30 microwatts at 3 meters. Yes?

Yep, that's right. And I finally got curious enough to look up the
actual regulation. According to section 15.225(a), intentional radiators
at 13.553-13.567 MHz are allowed 15,848 uV/m at 30 meters, which is
about 4.75 mW to an isotropic antenna in free space. There's also a
0.01% frequency stability requirement which would imply crystal control.
And any emissions extending outside the band have to be about 54 dB
lower, 30 uV/m at 30 m.

So if N9OGL's transmitions are legal power wise, he would basically be
broadcasting for the kids across the street. Maybe he could take song
requests. They can just shout out their front doors what songs they want
him to play.
