[wsjt-devel] Multithreading FT8 decoder in WSJT-X and DX-pedition mode

Hello Joe and all, . Multithreading FT8 decoder in WSJT-X can provide workaround to the latency issues being observed at the DX-pedition mode tests. . Multithreading FT8 decoder is already implemented in JTDX and this approach might be taken from the latest JTDX source code. . 73 Igor UA3DJY

[wsjt-devel] FT8 DXpedition mode test

It appears that when the fox gets busy, its response can be greatly delayed, which leads to wasted extra calls from the hounds trying for a roger from the fox. As others mentioned, perhaps the fox should give rogers higher priority than signal reports to newer hounds. (Also, maybe the hounds

[wsjt-devel] Band change patch

This patch was submitted Nov 2 but never applied.It comes from the bug identified in this thread where changing the rig freq from the rig does not adjust to the remembered power levels. https://sourceforge.net/p/wsjt/mailman/message/36101238/ Index: mainwindow.cpp

[wsjt-devel] DXpedition mode test results

There was no propagation on 20m and 30m, but on 40m and 80m I worked DX quickly and without problems. There were a few glitches that are hopefully not difficult to fix. 1. When the Fox answered my call at 01:02:00 (see the attached screenshot), his message appeared on the left panel but not on

Re: [wsjt-devel] MessageBox patch

I use the same cables on my TS590SG and my Winkeyer. They are cheap and they work. NOW if someone could get a fix for every TV in the house things would be better. Even on 100 Watts it causes some trouble but on 800 it is total destruction. TV Cable boxes and TVs are just not make the way

Re: [wsjt-devel] Public test of FT8 DXpedition mode March 6-7

Too bad, I was QRV at SK2AT and running a bit of FT8 with NA/SA @20m until about 30min ago when some aurora came along and transformed the signals to jingle bells and wasn't heard since. Looking forward to another try, either another test or for DXpedition. 73's and good luck with the test!

Re: [wsjt-devel] Status patch

Hi Mike, that was exactly my concern as NA is a valid, if somewhat cold, grid field. I will apply shortly as discussed. Thanks for the patch. 73 Bill G4WJS. On 06/03/2018 22:05, Black Michael via wsjt-devel wrote: Yeah...that works too...anything that doesn't look like a grid or is at least

[wsjt-devel] Add ft8d and ft8sim to makefile?

Hi folks, I am interested in integrating some software with FT8 by passing audio files into and out of the FT8 modem as provided by WSJT-X. I'm no FORTRAN developer, but it appears that I could utilize the `ft8d` command-line utility to decode WAV files, and `ft8sim` to generate them. Is that a

Can you run "ldd" on the jt9 executables?  That may point out what's different.  de Mike W9MDB On Tuesday, March 6, 2018, 1:26:40 PM CST, Doug Collinge wrote: I have done a fair amount of work to try to isolate the circumstances that produce the leak.-

I have done a fair amount of work to try to isolate the circumstances that produce the leak. - I used some spare partitions to build clean Ubuntu systems of various vintages. I installed the deb of 1.9.0-rc2, tested, then removed that and built it from the source using the libraries provided by

Re: [wsjt-devel] Memory Leak in jt9 Process

I found out there's no leak on Ubuntu 16.04.3 but there is on 17.10.  I upgraded 17.10 to gcc 7.3 thinking it might be a library leak and that didn't fix it either.  It only shows up on the multi iterationS that jt9 does under wsjtx.  de Mike W9MDB On Tuesday, March 6, 2018,

Re: [wsjt-devel] Audio input from RTP stream?

FT8 is already encroaching on the PSK subbands (or in the case of 17 meters right on top of the PSK subband) and probably others too.  PLEASE be a good neighbor and don't do anything to make it worse.  Everyone needs to share a very limited resource.  Just because FT8 is popular does not

Re: [wsjt-devel] Audio input from RTP stream?

Hi Phil, Your idea sounds reasonable. It might be a good way to enable wideband receiving -- that is, reception (of FT8, say) over a passband significantly greater than 5 kHz, currently the practical limit. The popularity of FT8 on the HF bands implies that wider sub-bands would be very
