Bill,

 

The big obstacle to a database as you suggest, is that some legislations allow people to use the plain call at another location without the need to sign say /A. Also the FCC allow continental hams to use their call in other DXCCs such as KL, KH or KP4.

 

Databases do exist that map calls that could be a number of DXCCs, such as GB or VP8, to the specific DXCC.

Hi Stefan,

that's too much latency. If you are receive only you can adjust your system clock to compensate but for Tx and Rx you are out of spec for using WSJT-X.

I often use an SDRPlay RSPduo with the accompanying SDRuno console software, that has about 350 mS of Rx latency, which is about the practical limit for HF FT8 use. The recently introduced FT8early decoding passes rely on Rx latencies no higher than that sort of level, with latencies higher than about 400 mS the FT8 decoding algorithm is compromised.

Hi John,

go to the "Settings->Colors" panel to see the highlighting options. As you will see there; highlighting new things per band or overall are both available.

WSJT-X does not have US State highlighting. This is mainly due to there being no readily available database in a suitable format that maps US calls to US States. A secondary reason is that even though WAS is a popular objective, it is rather geographically limited. If anyone were to contribute an accurate, well maintained database of *all* primary sub-entities Worldwide; then I'm sure such a source could form the basis of an excellent objective for DXers, after all main regional variants are already expressed as awards (WAS, DL Doks, JA Prefectures, UK Counties, Oblasts of Russia and many others, ...).

JTAlert and other applications that interoperate with WSJT-X are able to initiate QSOs with callers without having to locate the their CQ message in the Band Activity decodes window. E.g. with JTAlert (assuming "Settings->Reporting->Accept UDP requests" is checked in WSJT-X) you can simply left-click the call in the alerts panel to initiate a QSO.

with jtAlert,  in either the callsign display or decodes window, just click the call sign you want to work. 

No need to search the wsjtx window. 

The decodes window is very useful, as the callsigns don't disappear after the cycle is over. Bring is up with F9, or see the view menu. 

as for the wsjtx colors, i only have active is "my call in message' and "transmitted message'. other wise its too many colors which I can't remember anyway.

I should think so. It would be something like interpreting handwriting.

I am not a programmer and only have experience with machine learning in a theoretical capacity as the director of an R&D department working with such technologies in a totally different field.

You know, old experienced professional “sparks” on ships could recognize the person transmitting purely from his cW “handwriting”.

 

So yes, I think it would be possible.

 

However, as others have pointed out in this thread, there are already very good Cw decode programs out there. To what degree a system using ANN, or some variety of this technology, would seriously improve the decoding I do not know.

Hi John,

 

Decoding manual CW is not a particularly mathematical problem. The problem will be working out what are dots and dashes and inter-letter breaks, especially if the sender is not particularly consistent with speed. For example, CQ sent without an inter-letter break – your brain recognises it as CQ, but no mechanical process would. An AI approach is possibly a way to go, if you can find suitable vast amount of training data that has the equivalent text, but I think would require an inordinate amount of processing power. (And I don’t think generating pseudo-manual code with slight randomising of symbol length will generate valid training data.)

 

I found I could just about get fldigi to read my code sent on a straight key, after a few minutes. I found it quite hard work.

Hi guys,

Have an request.

Joe, with your crazy math skills and already existing talents in digital noise reduction, etc.; would you please create a much better CW  decoder!

See I, and many folks like me, have asymmetrical hearing loss & tinnitus from working around jets in the Navy, etc.. As such, my hearing prevents me from hearing cw right - it just all becomes noise & a blurry mess in my head.

So it it would really be nice if there was a far superior cw decoder with the ability to decode as well as FT8.  I have tried many of the packages available for pc-win 10, none of them work very well. Lots of t's & e's... in other words, more noise than conversion.

I think it would be really cool if you could manage to not only decode well, but do so in a broad band fashion as with wsjtx & decode several signals at once & & display callsigns for quick ID'ing.

It would really help. Thanks & 73

HI Bill,
 
Following up on this, I’ve been off the air for a few days but fired up WSJT-X today and got another freeze.  I’m sending you the last three .wav files that were saved consistent with your request below.  To me they just sound like normal audio and seem to terminate normally.  WSJT-X was up and frozen when I grabbed them and after I did, and closed WSJT-X, I checked and no more .wav files had been written.  I also took a short video showing WSJT-X with the waterfall frozen but the 15-sec timer still running and Flex DAX showing audio still being generated by the radio (that is, the radio and audio connection weren't frozen).  Being a video file, I won’t attach it here in case you’d rather I sent it via another means.
 
I’ve been getting these freezes since at least the first V2 and maybe before.  I can’t correlate them to anything.  During that time I’ve had four different Flex radios (quality is not a Flex Radio attribute - software or hardware) and several revisions of SSDR, CAT, DAX and Windows 10 software (I’m on 2004 now) running on three different fast laptops each set up from scratch.  I don’t use any third party AV software as they’re all basically malware themselves. The freezes seem to just “happen”.  Sometimes closing and restarting WSJT-X fixes it and sometimes I have to restart the whole computer.  I’ve lost at least one potential ATNO due to this.
 
Thanks for helping as always !

I happened to actually be in the no-decode state when I saw Ed’s post and your response.  The program controls are still responsive when this happens but the waterfall and input meter are frozen and of course no decodes come in.  I’m running a Flex 6700 (SDR 3.1.12, Win10 2004) and DAX is responsive while WSJT-X decodes are frozen.  Restarting DAX anyway doesn’t help.
 
So I set “Save all” for a few progress bar cycles and checked but out of a zillion files there were none covering that period.  Obviously the file doesn’t get generated when decodes are frozen and “Save” was off (somehow?) when it happened this time.  I’ve stopped and relaunched WSJT-X, it’s un-frozen again, and I’ve got “Save All” re-enabled.  So when it happens again I’ll grab the latest file and send it to you.
