Hi Joe, I get it. That’s a really neat case. It just dawned on me that having improved the SNR of the sync tone correlation by 3 dB, we should be able to raise the detection threshold a bit and possibly reduce the number of spurious (false detections) vectors. That might speed things up a bit

HI Joe- Just thought I would report it. It's not bothering me as I know what causes it. May be an issue for others if the on JT9 with a lot of additional JT9 stations. I See you on 160 tonight. Looks like Eu is coming through for the northern US stations. SA here so far. 73; Good DX Bill W2PKY

Hi Bill, OK, I now understand what you're reporting. Version 1.6.1 r5910 is quite a while back, code-revision wise. I tried to reproduce your effect with the current revision, r6041. I do see a small difference that depends on Rx freq: maybe one or two additional decoding seconds, with a tot

I would think, and I may be way off base here, the RCVR band-pass would have an affect on this also. My 1000MP has INRAD filters with Very Sharpe skirts. When operating both JT65+9, I've seen decode times slow down a tad. I just assumed ( maybe incorrectly ) WSJT-X was looking at what I had set

Hi Joe- My observation is that the total time to decode the received signals is influenced by the setting of the RX frequency. IE if setting the RX @ 300 Hz all decoding [65 & 9] proceeds rapidly. if setting the RX to 2K or above the JT9 prints are delayed significantly. My computer is a 4Ghz CPU

No doubt he did that because HA3LI sent him R-nn instead of just -nn when WB9OTX answered his CQ. I've not been able to figure out why some people do that, but if I'm not paying full attention I get caught out the same way. I'm really looking forward to using the new decoder! 73, Chris VE3NRT --

Hi Bill, I'm not sure that I understand your point. In JT9+JT65 mode, JT9 decoding is attempted only at frequencies above the "blue line" marker, set by the "JT65 JT9" spinner control. Decoding is always started first at the selected Rx frequency and mode, so the decode you care most ab

Hello JT Developers- Running 1.6.1 5910, noticed when mode is set to JT65 + 9 and the RX frequency is greater than 1500 the JT9 decoding takes a long time. If the RX is above 2000 and there are a few JT9 prints the last one could come at second 59. Regularly decode signals -26 -27 -28. 73, Bill

Wait. What? Very cool example, but I’m confused. When the user changes messages in mid-stream, my assumption was that the program would jump to the beginning of the new message symbol-stream, i.e. start at the beginning of a new message. But then the second message would decode with a big dt,

Hi all, Here's an amusing screen shot. WSJT-X was running with 2-pass decoding enabled for JT65. Note the two decodes of WB9OTX at Freq = 1856 Hz. Evidently he changed his Tx message from "HA3LI WBtOTX -21" to "HA3LI WBtOTX 73" in mid-transmission. The decoder gets the "73" message in its

Hi Steve, Thanks once more for your excellent work on the JT65 decoder!! I have confirmed your results using the test program jt65[.exe]. I then went ahead and merged your changes into v1.6.1 of WSJT-X; it's now performing at least as well as the WSJT decoder for the S/N=-24 dB files produced
