If interference is caused by spurious emissions, the operator of the transmitter must take whatever steps are necessary to reduce the spurious emissions as required by FCC regulations.

WebAccording to §15.407(b) (4) For transmitters operating in the 5.725-5.85 ㎓ band: All emissions within the frequency range from the band edge to 10 ㎒ above or below the band edge shall not exceed an e.i.r.p. of −17 dBm/㎒; for frequencies 10 ㎒ or greater above or below the band edge, emissions shall not exceed an e.i.r.p. of WebIn addition to the emission limits in Table 1, there are restricted frequency ranges, or bands, defined in section 15.205, in which only spurious frequencies may be produced. That is, the fundamental frequency of an intentional radiator cannot fall within one of these restricted frequency bands even if the transmit
