§97.313(c)(2)

Amateur stations transmitting on the 3.6-4 MHz segment may not emit an angle-modulated (FM or PM) emission that has a modulation index greater than 1 at the highest modulation frequency.

§97.305 and §97.307(f)(1)

Amateur stations transmitting on the 3.6-4 MHz segment may not emit a non-phone emission that exceeds the bandwidth of a communications quality phone emission of the same modulation type. The total bandwidth of an independent sideband emission (having B as the first symbol), or a multiplexed image and phone emission, shall not exceed that of a communications quality A3E emission.

§97.305 and §97.307(f)(2)

Only a RTTY or data emission using these specified digital codes may be transmitted on the 80 m band: Baudot, AMTOR, ASCII, or any technique whose technical characteristics have been documented publicly, such as CLOVER, G-TOR, or PacTOR, for the purpose of facilitating communications.
