      JT9 like JT65 is a long duration mode allowing very weak signals to be averaged and decoded.  On six meters, the propagation is either Sporadic E, Tropo Scatter, Meteor Scatter or F2.  These modes of propagation tend to be strong but “sporadic”, with very short durations or bursts of signal.  ISCAT, FSK441 and PSK2K are designed to exploit these very short duration bursts and are a much better choice for the six meter band.

      Ve1sky and I have worked on 6m

      It was an easy decode by both sides

      Although this mode isn't really optimized for 6m

      I am wondering if anyone has tried JT9 on 6 mtrs.  I tried a test with K0KUK on JT9-1.  I was able to hear his signal, in the speaker, and see a good trace but never got a decode.  Any ideas!!
