Part 97.311 Spread Spectrum FCC Rules for Ham bands

(a) SS emission transmissions by an amateur station are authorized only
    for communications between points within areas where the amateur
    service is regulated by the FCC and between an area where the amateur
    service is regulated by the FCC and an amateur station in another
    country that permits such communications.  SS emission transmissions
    must not be used for the purpose of obscuring the meaning of any
    communication.
(b) A station transmitting SS emissions must not cause harmful 
    interference to stations employing other authorized emissions, and
    must accept all interference caused by stations employing other
    authorized modes.
(c) When deemed necessary by a District Director to assure compliance with
    this Part, a station licensee must:
  (1) Cease SS emission transmissions;
  (2) Restrict SS emission transmissions to the extent instructed; and
  (3) Maintain a record, convertible to the original information (voice,
      test, image, etc.) of all spread spectrum communications transmitted.
(d) The transmitter power must not exceed 100 W under any circumstances.
    If more than 1 W is used, automatic transmitter control shall limit
    output power to that which is required for the communication.  This
    shall be determined by the use of the ratio, measured at the receiver,
    of the received energy per user data bit (Eb) to the sum of the
    received power spectral densities of noise (N0) and co-channel
    interference (I0).  Average transmitter power over 1 W shall be
    automatically adjusted to maintain an Eb/(N0+I0) ratio of no more
    than 23 dB at the intended receiver.
