Sec. 95.855  Transmitter effective radiated power limitation.

    (a) The effective radiated power (ERP) of each CTS and RTU shall be 
limited to the minimum necessary for successful communications. RTUs 
with powers in excess of 100 milliwatts must incorporate automatic power 
control to ensure the minimum ERP is used. No CTS may transmit with an 
ERP exceeding 20 watts. No fixed RTU may transmit with an ERP exceeding 
20 watts. No mobile RTU may transmit with an ERP exceeding 100 
milliwatts mean power.
    (b) For an IVDS system located in a TV Channel 13 station Grade B 
predicted contour, the maximum ERP shall be limited as follows:
