Amateur spread spectrum allowed

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.

If interference is detected by the receiver it will signal the transmitter to change frequencies B. If interference is detected by the receiver it will signal the transmitter to wait until the frequency is clear C. A pseudo-random binary bit stream is used to shift the phase of an RF carrier very rapidly in a particular sequence D. The frequency of the transmitted signal is changed very rapidly according to a particular sequence also used by the receiving station. The general concept of spread spectrum is to spread the RF signal across a broad range of the frequency domain. Generally with spread spectrum, the carrier frequency of the transmitted signal will continuously change over time, dragging the signal bandwidth with it all across the breadth of the amateur band from moment to moment.

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. ET Docket No.

Spread Spectrum : Part 97 Rules and Regulations. The following is no longer current. The most significant changes are the elimination of the APC requirement and the reduction of power limit to 10 watts. The reader is advised to consult the most current version of Part 97 rules prior to operation.
