- 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).
