Hi Chris,

one likely cause is your PC not being synchronized to UTC well enough. The WSPR decoder has a much larger tolerance for time difference than the FT8 one does. We recommend installing the Meinberg NTP Client application if you are running on MS Windows.

Hi Peter,

there are several ways you can do it. Environment variables can be set in MS WIndows at the system level, at the user level, and in each process. You probably want the user level option which will set it for all processes started by your user. You set them in the "Control panel->System->Advanced system settings->Environment variables" panel, just add a new user variable called FST4_NOSHAPING and give it a value of 1.

Which version of raspberry pi os?

cat /etc/os-release

Or you can try lsb-release -a

Paste the output.

Also before installing the dependency package make sure you run apt update to refresh the repository information.

Also make sure you’re on the latest updates - run:

apt upgrade -y 

then reboot.

Edited

If you are seeing good signals on the screen but can't decode them, check your operating mode one more time.  Some rigs will defaull to LSB for frequencies below 9 MHz.  However WSPR is ALWAYS sent using USB, regardless of the frequency band.  It's the opposite of RTTY which always appears as LSB, where the transmitted mark freq is lower than the space). 
Also, make sure the receive level indicator stays steady green.  +60 on receive might be strong enough to overload the decoder input.

Hi Dave,

Thanks for your report.  I'll try to respond to each of your many questions.

1. Your inferences about when Q65 decoding should start are not correct. 

Consider, for example, the 30-second submodes.  Transmission duration is 25.5 s.  These transmissions nominally start at t=0.5 s, so they finish at 26.0 s.  Add at least a second (we used 1.6 s) for possible clock errors at one or both stations.  If EME path delays are involved, add another 2.6 s.  The actual number we use for Q65-30x submodes is 27.6 s if "Decode after EME delay" is not checked, 28.8 s if it is.  Your observations yield essentially these numbers.

2. Yes, the decoder may sometimes remain busy after end of the Rx sequence.  This does not necessarily cause any problem.  Decoding always takes place first at your selected RxFreq, and results are reported as soon as available. 

3. Did you follow the advice in "Quick-Start Guide to Q65" and select "Fast" on the Decode menu ?

4. If you wish, send me a copy of the file "q65_decodes.dat" in your Log directory and I'll have a look at some relevant statistics.

locked WSJTX v2.4.0-rc1 decode delay Q65 modes #install

David Redman
 

to the team congratulations on the new Q65 mode which I find of real interest for my small station EME activities
To Joe and Bill.
I tested the new Q65 mode to gain some experience with the sample files
This was on 3 pc's , specification per the attached file , all Q65 sample files decode ok on each pc but in the real world the decode 'light' comes on some seconds after when I think it should do and decoding overruns into the next cycle as per the chart attached. Checked all settings and are per Q65 Quick start guide.pdf
My chart below only covers mode A at the different time intervals
So what am I doing wrong ? , clearly lower spec pc is worse but all the 3 pc's run fine on JT65A or B or C and FT8 modes
In addition can you clarify the decode duration per mode and the minimum PC requirement for this new mode
A minor point in the Quick start Guide section 10. the sub directory 12D_Rainscatter_10GHz should of course be 120D................

Dave G4IDR

Observations            
1) decoding starts later than expected i.e Q65-30A should start decoding at t=25.5secs and end at t=30secs worse case i.e. before the next cycle )    
2) decoding running in next cycle shown    
3) in some cases into 2nd cycle          
4) base Processor load is with WSJTX running in monitor mode
  before decode starts , Load in columns is during decoding
5) All these PC's decode JT65A or B or C within <2 secs after t=52.5secs
6) All these pc's decode FT8 correctly before the end of decode period 
  and do not over-run into the next cycle except computer B when 
  decoding more than 30 signal in the period  
7) G , DL , OZ signals decoded today on 2m Q65 - 30C mode
  but decode over-runs as above

Then install WSJT. I believe you can double click on the .deb file in the download directory to accomplish this.. IE the dpkg command line is simply replaced by a double click on the file.
