Sec. 15.219  Operation in the band 510-1705 kHz.
    (a) The total input power to the final radio frequency stage 
(exclusive of filament or heater power) shall not exceed 100 milliwatts.
    (b) The total length of the transmission line, antenna and ground 
lead (if used) shall not exceed 3 meters.
    (c) All emissions below 510 kHz or above 1705 kHz shall be 
attenuated at least 20 dB below the level of the unmodulated carrier.
