What is the characteristic of the JT65 mode?
Pick an answer to check it.
Answer: B. Decodes signals with a very low signal-to-noise ratio
JT65 is designed to decode signals with a very low signal-to-noise ratio, well below what the ear can hear. The 65 refers to the number of tones, not its bandwidth or baud rate.
Tip: JT65: decodes signals buried in noise.
