      Greetings:

      Trying to convert from JT65-HF to WSJT-X and I am trying to figure out the
      band pass on the "Wide Graph". When using JT65 only, dial 14076, what is the
      upper and lower limits, on the graph, for JT65 signals? I am trying to
      figure out where to call CQ and still be in the old JT65-HF -1000 to +1000
      range.

      The same question would also hold true for JT-9, dial 14078, what are the
      upper and lower limits on the graph for normal JT-9 operation.

      I have the graph open from 0 to 2800 Hz and can get to 4000Hz, if needed.

      I have not started to explore combined modes on the graph. That is the next
      step.

      Thanks and 73

        JT65-HF's "0" point was 1270.5 Hz. Thus -1000 would be 270 Hz and
        +1000 would be 2270 Hz. It is easier to remember 300 - 2300 Hz ....

        The majority of JT9 activity is between 14.079 and 14.080 (RF) - for a
        dial frequency of 14.078 that's +1000 - +2000. If you have a rig that
        is capable of "wideband" (4 KHz receive) operation, JT65 will be from
        +300 to +2300 ... JT9 will be between +3000 and +4000 with a mixture
        in between (JT65 is expanding up a bit and JT9 is slowly sliding down
        a bit).

        73,
