Tnx QSO Spiros, good copy despite high thunderstorm QRN. A lot of JT9 and FT8 activity tonight. Just worked G8TTI for the first time (station number 164 on 472kHz). 73, Rik ON7YD - OR7T Good JT9 QSO.
​Hello Ricardo, thanks for the feedback. I haven't used a virtual audio cable (VAC) so far, but I will have a look at it. 73, Rik ON7YD - OR7T Van: [email protected] <owner-rsg
​Hello Paul, thank you for the report. I will try to reproduce the bug and fix it. 73, Rik ON7YD - OR7T Van: [email protected] <[email protected]> namens N1BUG paul@

Hello Paul, currently you have to subtract 3dB for JT9-2 and 7dB for JT9-5 to get the "true" SNR. A new version of SlowJT9, with correct reports and the cycle bug fixed, will be uploaded later today.
Paul, all, before I started programming SlowJT9 I did a "dry test" by generating JT9(-1) and JT9-2 WAV files with a known SNR and feeding these to the JT9 decoder of the WSJT-X suite (the JT9-2 WAV f
I just uploaded a new beta version of SlowJT9: v0.9.02 [12 Nov 2018] Bug fixes: - Non fatal bug that that corrupted the cycle calculation fixed. Changes: - Calculation of the report (dB) corrected fo
Hello Eric, yes, a scale factor of 2 and 5 is used. I hadn't any information about the old JT9-2 and JT9-5 modes and those scale factors seemed the most straightforward to me and make the conversion
Hello Paul, decoder.txt seems OK. I am sorry if I gave the impression that I thought you were complaining. Certainly not, all reports on crashes are abnormal behaviour are welcome. But these rare cra
Hello Eric, Paul, as Paul says the original JT9-2 and JT9-5 symbol lenghts are probably optimized for "good use" of the 2 minute and 5 minute cycle. JT9(-1) has a exact symbol length of 6912/12000 =
I just had a look at the CPU usage of my computer: it is wobbeling between 2% and 5% but peaks to 40% if the JT9 decoder is invoked. I am afraid that invoking 3 instances of the JT9 decoder at (almos
Hi Mauro, the link is still the same:http://472khz.org/SlowJT9/SlowJT9_setup.exe​ 73, Rik ON7YD - OR7T Van: [email protected] <[email protected]> namens Mauro
Hi Paul, it seems that we will have to make a choice: - either the old JT9-2 and JT9-5 standard and only decoding one mode at a time - or keeping the current JT9-2 and JT9-5 parameters and keep the o
Hello Antonio, solid copy of your signal on JO20IX: 2216 -19 -0.9 1309 @ IK1HGI BCN JN ​ Try a QSO? 73, Rik ON7YD - OR7T Van: [email protected] <owner-rsgb_lf_group@blacksheep.
Hello Antionio, the signal just above 1200Hz is most likely WSPR (by counting pixels I estimate its length at 110 seconds, a JT9-2 transmissions takes only 98 seconds). Either someone transmitting ou
Hello Jim, all, my plan was that SlowJT9 will decode all JT9 submodes and show them on the same decoder window. The user can see for each decoding what the submode is (the M parameter in the decoder
Hello Paul, all, the original slow JT9 submodes make better advantage of the cycle length than the ones currently used in SlowJT9. Eg.: where the current JT9-5 version has a transmission duration of
Dear all, I just uploaded a now beta-release of SlowJT9 (v0.9.03). The main changes are - The option to save all decoded messages in a text file (file "decoded.txt" in the folder "extra") - The optio
