I can't find the reference if there is a limit on the power output for a comm radio on the aviation bands? Can someone cite it for me, please?
TIA.

It's likely in an FCC document. They typically spell out the max transmit or radiated power in each frequency band.I can't find the reference if there is a limit on the power output for a comm radio on the aviation bands? Can someone cite it for me, please?

I see that there's a lower limit of 10W for "Aeronautical multicom" and "Aeronautical advisory". Perhaps the latter is for an airport's unicom ground station. I wonder if airborne comm transmitters with more than 10W output are required to limit power on frequencies designated for multicom. IIRC, most GA comm transmitters are 10W or less on all freqs.Here's the reg: http://www.gpo.gov/fdsys/pkg/CFR-2012-title47-vol5/xml/CFR-2012-title47-vol5-part87-subpartD.xml
It appears the limit for VHF comm is 55 watts.

Those two are for the ground stations licensed as those types. The restrictions associated with them are NA for aircraft comm systems.I see that there's a lower limit of 10W for "Aeronautical multicom" and "Aeronautical advisory".
