Bill G4WJS  (lots of Bills here....)

"If I understand correctly, you are saying that while using one of the WSJT-X "Settings->Radio->Split Operating" options you selected a Tx audio offset, say 1000 Hz, on a VFO dial frequency, say 14,074 kHz, and observed the transmitted signal was *not* at 14,075 kHz (lowest tone frequency)"

Yes, this is exactly what I am saying.  And as I pointed out before, this also happened to NU4E during the contest so the problem is not unique to me.  We discussed the problem on the phone during the contest.  We both understand how the "split" operation normally functions.

I was not able to clear this problem by rebooting the computer. Probably I can reproduce this again.  First chance I get I will bring up he SO2R operating conditions and see (using 1000 Hz TX audio selection on the waterfall} exactly what the split VFO is reading while transmitting and then measure the frequency it is actually transmitting.  When the problem is present, both the FT signal and the tune button have the same problem.

"Why do you need to use anything other than "Settings->Radio->Split Operating->None" when you are using an all digital audio chain, and a rig with variable Tx and Rx bandwidth?"   

As Frode previously pointed out: The purpose of those two settings (Split - Fake It) is to make sure that the FT8/FT4 audio signal stays between 1500 and 2000 Hz (to avoid the risk of intermodulation in the audio passband). If you select an audio TX frequency (the red "goalpost" in the waterfall window) between 1000 and 1499 Hz, say 1200 Hz, you would expect your signal to be transmitted on e.g. 14,075.2 kHz. To transmit an audio signal in the 1500-2000 Hz sweetspot, the USB "carrier" or dial frequency is therefore moved down from e.g. 14,074  to 14,073.5 kHz. Your audio signal will be 1700 Hz, right in the 1500-2000 Hz sweetspot. Your signal will be transmitted on 14,075.2 kHz, which is the sum of  14,073.5 kHz + 1700 Hz.

WSJT-X User Guide as has this info: " Either method will result in a cleaner transmitted signal, by keeping the Tx audio always in the range 1500 to 2000 Hz so that audio harmonics cannot pass through the Tx sideband filter. "

I will be back later with the info you want, Bill.   I DO appreciate you responding.

"....for a long time now but recent versions sometimes fail to decode at start or
after some period of time even though nothing outside of WSJTx has changed."
This caught my eye. For several years, I have been running PowerSDR (v2.7.2) to control my Flex-1500 on a Windows 7 (Home) PC. After, several hours of operating WSJTx, I notice that the DT times on decodes will have crept up. Once it gets to around 2.0 seconds on my set up, I will start to lose decodes. I can clear the problem by stop/starting PowerSDR. I am now in the habit of restarting PowerSDR once a day as a preventative measure. I have had this issue on WSTJx v2.2.2 and had it on many previous versions 1.x and 2.x.

I read the time sync threads with some amusement at the agonizing over setting precise time at least for FT8 on HF.   At the cottage, Internet is spotty and the old laptop kept there for ham radio can be minutes off after being turned off for a week or several.  In about the same elapsed time as it would take to set up a hotspot, connect (hopefully) and sync online, I first manually set the computer clock to the minute by using the smartphone time stamp.  Then by watching the waterfall, eyeball how much to change the time so that the signals centre between the interval lines, then set the time.  A second attempt may be needed if the average DT is too far off - not getting decodes of (almost) everything.  It’s as much a test of reaction time as anything else.

 

Of course this lacks a level of precision, but it does get me on the air and making QSOs.  HI

locked Need help finishing setup

dhopkins04573@...
 

Good morning all, thanks for having me.  I am attempting to setup ft891, lcd auto tuner, shortened dipole mounted vertically with a Raspberry Pi 4, 8 gbyte currently running WSJT-X 2.2.2. Audio interface is a Sabrent USB external adapter. Optionally rig control can be by flrig but there is no difference in the way the system operates. Both WSJT-X and the Raspberry Pi operating system were installed with no errors, and start as expected.

Receive sound level is set as suggested.  The waterfall and decodes operate as you expect, in fact, I am a little surprised at how many signals are decoded.  The system will run in receive for extended periods of time in receive/decode and properly uploads to PSKReporter.

The problem occurs on transmit, either ‘tune’ or normal transmit.  The system appears to properly enter transmit mode, although no tone(s) seem to be generated.  This may be a problem with the audio setup, I don’t know at this stage.  After the transmit, the system appears to return to receive mode however the green audio in level remains at zero and no decodes happen.  The waterfall does operate normally, showing about the same number of signals as it did previously.

Closing the WSJT-X window does not shut down the system properly.  Reopening WSJT-X results in an error message to the effect ‘another instance is running.’  None of the options in the dialog box operate correctly.  Recovery from this state requires a ‘kill’ from the task manager or a system reboot.

An unrelated symptom, which I assume is different is that neither the time bar at the bottom right of the main page, nor the ‘test CAT’ button on the settings audio page are or ever turn green.  The test CAT button does seem to do what it should.  A short time after it is pressed, the ‘Test PTT’ button is enabled, and does turn red when enabled.  Enabling it and then disabling it does not interfere with the operation of the receiver nor decodes.

All cabling in the system is protected with ferrite beads, and the components are bonded.

thanks for your help.

As post earlier I can consistently force the “no decode” failure, decodes stopping after several minutes of operation in spite of good signals on the waterfall. Bill posted if FILE ---> SETTINGS---> GENERAL --> START NEW PERIOD DECODES AT TOP was enabled this triggers a know fault. Deselecting it and saving didn’t resolve the problem. Was the setting “stuck” in a configuration file somewhere?  I uninstalled WSJT-X and deleted all other files relating to it. Reinstalling … the fault cleared.

As Bill stated, that’s already taken care of - which brings up a point that needs to be made. As a person who has helped more than one blind ham a great deal over the years, one in particular for the last 40 years, I would request that you pay vey close attention to what is stated and what is not.

Hi OM,

the green lines indicate the start/end of T/R periods. The signals look like FT8, yo probably want to reduce the "N Avg" spin box control to 1 or 2 to slow down the waterfall. You are working with a quite narrow bandwidth, I expect your rig bandwidth is more than the 1200 Hz width of the waterfall. Either expand the Wide Graph window, or increase the "Bins/Pixel" spin box to increase the decoder analysis window. I will assume the uneven spacings of the T/R periods is due to your transmissions, if that is not the case then there may be issues with system performance causing audio data to be lost.

You may find reviewing the operating tutorials in the WSJT-X User Guide useful:

Williams, G (af8c)
 

I am going to take a wild guess that your CPU is too slow or to busy to keep up with WSJTX for some reason. It appears there is not enough CPU power to keep up with the timing.  That's because the horizonal lines that are supposed to be 15 seconds apart, are not scrolling often enough.  My guesses come from last night's problems with my slow Windows 7 netbook as described below.

In my opinion, if not in fact, the WSJTX User Manual does not suggest that you need dedicate (buy?) a quite fast machine, perhaps with Solid State Drive, with no other unnecessary processes running on the side. And there might be other requirements for the PC also. 

My slow Netbook's audio going to the SL to a TS2000:  I monitored the audio being transmitted with the PWR/TX MONI function on the front panel of the TS2000.  There were obvious "burbles" in the audio going out and I was not getting many QSOs. Upon investigation in the PC with Task Manager I found unwanted processes running in the background, such as several instantiations of the browser. ( I don' know why they were "stuck" in the list when I didn't have a browser open)  I was not able to stop enough unwanted processes in Task Manager to affect (remove) the burbles in the audio. Well, this netbook had been pinched into service due to problems with other computers at the time.

Moral to that story:  listen to/monitor the audio being transmitted.  Yes, I suppose not all radios have that ability.

Ways to find out more about your PC's workload follow.

Are you running a slow old PC?  Replace it with something newer.

Learn how to use Task Manager  (found by right clicking in the Taskbar) .

Looking at the Desktop, or in the Applications Tab in Task Manager,  close all other unnecessary applications that might be running, but NOT WSJTX,  When Task Manager is running, click on the Performance tab to see how busy the CPU is, and click on the Application Tab to see if anything is running that is not WSJTX related. All other applications need to be stopped.

Next, is your hard drive light illuminated/ flickering a lot, a majority of the time?  Perhaps your hard drive is too busy doing something that is not obvious in the Task Manager.  Perhaps you have an antivirus/antimalware application running? Some anitmalware software can tie up your PC something fierce.

Unfortunately, a deeper dive into Task Manager control would take up too much space here.

Yep, I can get wordy.

Hello Frode

I appreciate your comments.  The problem I was having was - while split and fake it operated just as you described, the actual desired audio frequency was not correct.  I verified this by monitoring my actual transmitted signal on a second radio running WSJT-X.   The ACTUAL transmitted audio had a constant offset from the desired and expected frequency.  NU4E also experienced this problem at his station.  The offset caused severe problems when operating because the frequency (say 1000 hz) I thought was being sent was not sent.  Instead 1500 Hz was actually being sent.  (I don't remember the actual offset - sorry).  I verified this on the second independent radio and WSJT-X setup.  I was making very few QSOs when this happened, even with 1 KW output.  Once I stopped using split or fake it, I verified the ACTUAL transmitted signal on the independent WSJT-X and the problem was gone.  I started making QSOs at good rates.  I run SO2R FT8 & FT4 so verifying this problem was easy.  My second SO2R radio setup never experienced this problem.

Bill N4iQ
Hi Bill,

your comments do not clarify the issue you are reporting. Audio offsets are irrelevant when checking the behaviour, what matters is the RF frequency the signal is sent on. If I understand correctly, you are saying that while using one of the WSJT-X "Settings->Radio->Split Operating" options you selected a Tx audio offset, say 1000 Hz, on a VFO dial frequency, say 14,074 kHz, and observed the transmitted signal was *not* at 14,075 kHz (lowest tone frequency). If that is what you are observing then please tell us what VFO dial frequency is being selected for your Tx VFO when this happens?

As an aside, why do you need to use anything other than "Settings->Radio->Split Operating->None" when you are using an all digital audio chain, and a rig with variable Tx and Rx bandwidth?
