                       TITLE 47--TELECOMMUNICATION
 
              CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION
 
PART 15--RADIO FREQUENCY DEVICES--Table of Contents
 
                    Subpart C--Intentional Radiators
 
Sec. 15.223  Operation in the band 1.705-10 MHz.

    (a) The field strength of any emission within the band 1.705-10.0 
MHz shall not exceed 100 microvolts/meter at a distance of 30 meters. 
However, if the bandwidth of the emission is less than 10% of the center 
frequency, the field strength shall not exceed 15 microvolts/meter or 
(the bandwidth of the device in kHz) divided by (the center frequency of 
the device in MHz) microvolts/meter at a distance of 30 meters, 
whichever is the higher level. For the purposes of this section, 
bandwidth is determined at the points 6 dB down from the modulated 
carrier. The emission limits in this paragraph are based on measurement 
instrumentation employing an average detector. The provisions in 
Sec. 15.35(b) for limiting peak emissions apply.

    (b) The field strength of emissions outside of the band 1.705-10.0 
MHz shall not exceed the general radiated emission limits in 
Sec. 15.209.
