Restrictions
Amateur stations transmitting on the 18.11-18.168 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.
§97.307(f)(1) and §97.305(c)
Amateur stations transmitting on the 18.11-18.168 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.
§97.307(f)(2) and §97.305(c)
Only a RTTY or data emission using these specified digital codes may be transmitted on the 18.068-18.168 MHz segment: 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.
§97.305 and §97.307(f)(3)
The authorized bandwidth for the 18.068-18.168 MHz segment is 2.8 kHz.
§97.305 and §97.307(f)(3)
Contest activity shall not take place on the 17 m band. Non-contesting radio amateurs are encouraged to also use the contest-free bands during large international contests.
