Hello Eric, all,=20

arecord -c 1 -r 12000 -f S16_LE capture.wav
sox capture.wav capture_tmp.wav speed 2.0
jt9 -9 -d 3 -S 300 capture_tmp.wav
cat decoded.txt

That is amost exactly what I am doing in SlowJT9, just i= n a more fancy (user friendly) way ;-)=20
Does the speeding-up includes averaging ?=20

Correct, the original timings were fit into a "window" vs. simple= =20
scaling.  Since the slowJT exe wouldn't run in WINE, I just = ran a few=20
commands to decode K5DNL:=20

jt9 -9 -d 3 -S 300 capture_tmp.wav=20

jt9 is the standard executable decoder from WSJTX v1.9.1.=20
