Hi Bill I've been testing the new jt65sim.
Current command line is: jt65sim -m C -n 1 -d 40 -S -s \-15 -t 2.5 -f 10 -M "G3WDG VK7MO -15" With 11025 sample rate, I find WSJT decodes only the first file tried (it can be _0001, _0002 etc). Subsequent attempts to decode another file in the set of 10 fail. WSJT-X is fine with all 10. WSJT-X: 0001 -14 2.6 1498 #* G3WDG VK7MO -15 f 0002 -14 2.5 1500 #* G3WDG VK7MO -15 f 0003 -14 2.5 1499 #* G3WDG VK7MO -15 f 0004 -14 2.5 1498 #* G3WDG VK7MO -15 f 0005 -14 2.5 1501 #* G3WDG VK7MO -15 f 0006 -14 2.5 1503 #* G3WDG VK7MO -15 f 0007 -14 2.5 1503 #* G3WDG VK7MO -15 f 0008 -14 2.5 1501 #* G3WDG VK7MO -15 f 0009 -14 2.5 1500 #* G3WDG VK7MO -15 f 0010 -15 2.5 1500 #* G3WDG VK7MO -15 f WSJT: 0_0001 12 -21 2.5 226 16 * G3WDG VK7MO -15 1 10 I also tried 40Hz spreading at -23 with 11025 with WSJT-X and found AP and no DS did not decode anything, whereas it gets 2/10 with 12000 sample rate. It does OK however with DS with these -23/40Hz 11025 signals. Perhaps the resampling on very marginal signals like this is responsible? I was not successful in changing to 1000Hz base frequency by adding -F 1000 to the command line. Maybe I'm not using the correct command?
