JT9 is a very narrow 9-FSKFrequency-Shift Keying mode for making contact (QSO's) under extreme weak-signal conditions. JT9 is about 2 dBThe decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, here the strength of a received signal. more sensitive than JT65A while using less than 10% of the bandwidth.
