Decodes signals with a very low signal-to-noise ratio✓Richtige Antwort
Symbol rate is 65 baud
Permits fast-scan TV transmissions over narrow bandwidth
Erklärung
JT65 was designed for moonbounce, where signals sit far below the noise, and its heavy forward error correction and slow symbol rate let it decode signals well below what the ear can hear. Its bandwidth is set by 65 tones and it is much slower than 65 baud, so the other descriptions do not fit.
