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).
