Hi Ko, Thanks for the decode, not bad a -10 db at one point. There must be a character limit on the Tx text box (Tx1) I have used as there is more than you have decoded. I will try placing the same t

Dear Gary, LF Group, Well, no problem copying your sigs, and I think I should have been replying to you OK with "G4WGT M0BMU IO91" (The first standard TX message), but obviously not OK at your end! 2
LF, I will QRT at 2200utc, thanks for all the replies & decodes etc. It seems some interest has been generated. So, I will try for a 2 way QSO tomorrow night if possible, I will start calling CQ (in

Also, Gary, what frequency Tol setting do you have? I see Jim's freq reading is -77Hz, so if you have Tol set to 50Hz, for example, it'll miss Jim's signals. It defaults to 400Hz at startup, so
Jim, Andy, Thanks for report Jim & comments Andy. Must be at my end. As far as I can see it should be decoding, I will check the sampling rate calibration if I can work it out :-(( I monitored HF ban
JT4 is based on the old 11025Hz sampling, which is badly supported by modern soundcards unlike WSPR which is based on 12kHz sampling. This has lead many an op to get poor decoding performance on ot

In its plain text mode which you have used, it can cope with just 13 characters. See http://www.g4jnt.com/Coding/JT4_Coding_Process.pdf and the WSJT documantation Andy www.g4jnt.com 2010/1/19 Gar
Overlapping emails :-) Think this was answered in the one just sent. JT4 and JT65 have similar input message formats, its just the to-air coding and FEC technique that is very different They do
Ah... I wonder. Jim's DT setting for your sigs is around +2 seconds. Which means in the opposite direction it would be -2s. This is a bit marginal. The WSJT modes were designed originally fo
