Note there are other digital modes operating in the vicinity of these
frequencies besides JT65A. Anything you hear in a ham band that isn't
voice or CW is likely to be digital a mode used by radio amateurs.
Modes in common use include Baudot RTTY, PSK31, MFSK, Winlink, Pactor,
Hellschreiber, Olivia, others. Every once in a while I still even hear
Clover being used. :-)
