Yaesu FT-4XRRADIATED SPURIOUS EMISSIONS

Rule Part No.:          FCC Part 15 Subpart B

Requirements:        FCC Part 15.109(a) Radiated Emission Limit

FCC Part 15.109(f) Radiated Emission Limit
For a receiver which employs terminals for the connection of an
external receiving antenna, the receiver shall be tested to demonstrate
compliance with the provisions of this section with an antenna
connected to the antenna terminals unless the antenna conducted
power is measured as specified in §15.111(a).


FCC Part 15.33(b)(3) Frequency range of radiated measurements

FCC Part 15.35(a) Measurement detector functions and bandwidths

ANSI C63.4 Methods of Measurement of Radio-Noise Emissions from
Low-Voltage Electrical and Electronic Equipment 9 kHz to 40 GHz

  • 6.2 Operating conditions
    § 6.3 Arrangement of EUT
  • 8.3.1 Exploratory radiated emissions measurements
    § 8.3.2 Final radiated emission measurements

The scanner receiver spurious emissions are to be measured when the
receiver is in the scanning mode and repeated when the scanning is
stopped, all while the antenna terminals are terminated into a non-
radiating 50 Ω load.
