The second item is a rule change that allows amateurs to use higher power from spread-spectrum communications. Not too smart, unless he was trying to hide other stuff that would have gotten him into even more trouble. This should make it easier for hams to experiment with spread-spectrum techniques.

In response to a ARRL Petition regarding spread spectrum issues, the FCC released a Notice of Proposed Rule Making NPRM on March 16 WT Docket No , proposing to amend Part 97 to facilitate the use of spread spectrum communications technologies by eliminating the requirement that amateur stations use automatic power control APC to reduce transmitter power when the station transmits a spread spectrum SS emission and reducing the maximum transmitter power output when transmitting a SS emission. Spread spectrum techniques are methods by which the information signal of a particular bandwidth is intentionally spread in the frequency domain. At any point of bandwidth the SS emission occupies, either the power spectral density of the transmitted signal is reduced to a comparatively low level or the duration of a transmission on any frequency in the frequency segment is very brief. Consequently, stations in the same area can transmit SS signals without causing harmful interference to or experiencing harmful interference from each other or a station transmitting a non-SS signal over the same spectrum segment.
FCC News: Man Fined $7,000, Spread Spectrum Rules Revised
Spread spectrum SS uses a wide bandwidth which would cause too much crowding on the relatively narrow bands below UHF. Last edited by wileyj Register to edit.
Back in , the RF world got very excited about the possibilities of using spread spectrum for ham radio. Listed below is some historical information related to this movement -- FCC's initial proposed regulations that would make this possible, and comments from the community about these proposed regulations.
