For the WF to look correct in the vertical ( and for
WSJT-X to work correctly ) the A-D converter ( sound card device )
must be at set to 48kbps ( 16 bits ) , the data must be presented
to WSJT-X uninterrupted and the CPU must have enough available
cycles to process and display the data uninterrupted. LatencyMon
would tell you if you PC is up to the task. Or you might have an
unstable sound card device. It might be worthwhile to try a
different sound card device to try and isolate the problem.

Joe, one other question. How much disk space do you have? Reason I ask is when Windows gets to where it has less than 10% available weird things start to happen.

I do several times a year, have the Windows disk utility clean out old updates to help keep more file space on the disk. One thing you might try is to turn on save audio. Then after a few minutes turn it off, then see what happens when you have wsjt replay the files. Don't leave it turned on as it will run you out of disk space. On a few rare cases I have had vendor USB drivers go corrupt. Deleting them in the Device Manager along with their software allows a clean reinstall of the USB drivers.

Hi Reino and all, this type of waterfall display occurring spontaneously is symptomatic of a disrupted audio stream being delivered to WSJT-X. The shortening of the periods implies many missing sample frames and the broadening spectral display of signals would be due to the discontinuities around missing sample frames that translate to noise. If I were experiencing this I would look for other applications or system components using large amounts of CPU or I/O resources, or perhaps excessive virtual memory usage thus causing all other applications to have to wait for memory. On Windows the Task Manager application and it's related Resource Monitor application should help to identify the culprit applications or services. 73 |

Thanks Bill!
I have blocked any other services (and there were a LOT of hidden background applications with automatic permission) from accessing the microphones, and so far that has solved the problem! Thanks again!

Reino,
The WSJT-X User Guide says, "Be sure that your audio device is configured to sample at 48000 Hz, 16 bits." That is what I have it set for. My audio settings has two choices for 48000 Hz 16-bit; one channel and two channels. Mine was set to two channels so I changed it to one channel. So far so good. I'll see what happens after a system re-boot. Thanks for for suggestion. 73, Steve KS3K |

Hi Jim,
Can you tell me where I can find the Audio Directory?
Thanks

Subject: Re: [WSJTX] No decode, waterfall
compressed Joe,
I went back and reread your previous posts and have two questions for you.
1. You said you had Meinberg
running, but you didn't say you confirmed it was working correctly by going to
https://time.is to confirm it was working. Did you check it on that
website?
2. Besides the other things
mentioned, make sure your anti-virus program is not scanning the audio
directory. Have you done that?
Unless the others who say they
are having issues bring it to this discussion list, the developers will not
"hear" their issues. Back when I worked, one of IT issues I had were people were
complaining to everyone about computer issues, except those who could actually
help them. They need to be on this list to get help.

Steve, Bill explained the most probable real reason for the ’compressed’ waterfall and wider noise like signals on waterfall i.e. about half of audio samples are lost due to some overload in PC. I don’t think that the one channel setting as such solves your problem, the PC overload may have just went off and may return at any time due to some background processing. Good luck! Reino, oh3mA |

WOW! Absolutely amazing. Have no idea why this would be the simple solution, but it does work. I tried it with the "Sound" window in Control Panel on and off (window open and closed after clicking the Mic icon once). My program went back and forth from crap to normal and is now staying normal as long as the "Sound" window remains open.
Sad that such a simple solution was out there and the developers have not seen that and/or have not or can't work in a fix. Thanks Steve, KS3K Joe, W7RNX |

Hi Bill and Reino,
With nothing running except Chrome browser, I typically get between 5-20% CPU usage. After I start WSJT-X, my CPU usage goes up to 75% or more, the waterfall looks "compressed" and I get no decodes. WSJT-X only uses about 2.8% of that CPU usage. The two processes that use the most CPU are Windows Explorer (23.6%) and Service Host: Capability Access Manager Service (18.7%). When I open the Audio Devices, Recording, Microphone (USB Audio Codec) window, my CPU usage drops to about 35%, the Service Host process is gone and Windows Explorer takes only 6.0% CPU. My waterfall looks good and I get good decodes. I can run like this for hours without any problem; unless I close that Audio Devices window and try to transmit (even when transmitting into a dummy load with the power level on the IC-7300 set to zero, the problem reoccurs). How do I keep this Service Host process from even starting? (If that is even the culprit.) If I kill Windows Explorer, I lose my desktop. BTW, I have no problem with using PSK-31 with DM-780 (from HRD) and no problem using FLdigi for CW decoding. I'm not dead in the water with WSJT-X. My workaround with the Audio Devices works every time. It's just a nuisance now. 73, Steve KS3K |

Try shutting down both chrome & explorer! Neither are needed to run wsjt-x & both are memory & cpu hogs! See how much your cpu usage is reduced, then see if that helps you wsjt-x function properly. Further, try running only one at a time any other time; as chrome & explorer conflict w/each other frequently. I don't even use "exploder" anymore. 73 - John - N7GHZ On Sat, Mar 28, 2020, 7:19 PM Steve Ikler <ks3k@...> wrote: Hi Bill and Reino, |

The two processes that use the most CPU are Windows Explorer (23.6%) and Service Host: Capability Access Manager Service (18.7%).Hi Steve, something is not right there. Processes that should probably be idle most of the time should not be using huge amounts of CPU resource like that. For example if you have a quad core Intel CPU, which has 8 independent CPU threads of execution, then just 12.5% average CPU time is one CPU core thread running at 100%. That happens normally for short periods when a program is only CPU bound, like the FT8 decoder, but should not happen for something like Windows Explorer which is your Desktop that should be basically idle waiting for you to click an icon. The service host is part of the Windows infrastructure, there will be several running all the time, each one hosts one of more services. Services are background non-interactive tasks that do essential housekeeping. A service that uses excessive CPU time is potentially a problem. Some services do use a lot of CPU time now and again, for example an anti-virus scanner. It can be tricky to work out which service is consuming excessive resources. You can list them all from a command prompt with the 'net start' command, but that doesn't help much. Here's a link with some information on exploring Windows services and tracking down potential issues: https://www.howtogeek.com/school/using-windows-admin-tools-like-a-pro/lesson8/ Don't be tempted to stop services just because you do not know what they are there for, you will see many web pages showing how to stop numerous services to get a faster machine. This is generally a false economy a you will end up with a substandard system. There are often a few services that are completely unnecessary, perhaps installed by your PC vendor, but in general services do not affect performance unless something is going wrong. You are better to track down the problem rather than using a scatter gun strategy to solving performance problems. BTW, your problem is almost certainly one of those two processes using some other resource in excess to the detriment of all other processes. E.g. a single process running 100% on one CPU thread could be consuming memory or some other resource continuously, thereby blocking any other process needing the same resource(s). 73 Bill G4WJS. |

Chrome browser was open only so I could use Groups.io to reply. It is not running when I use WSJT-X. Windows Explorer is a background process started by Windows. It is not in my list of auto startup programs and I don't intentionally run it. Perhaps you are thinking of "File" Explorer which is also not in use. 73, Steve KS3K |

Thanks for your comments, Bill.
Immediately after boot-up my CPU usage is around 5-10 %. Windows Explorer uses 1% of that. After starting WSJT-X my overall CPU usage jumps to around 75% and Windows Explorer jumps to 25%. After opening the Sound Properties for Recording and clicking on the USB Audio Codec, my overall CPU usage drops to around 25% and Windows Explorer drops back to 1%. I agree with you that "something is not right here". It is strange that just starting WSJT-X causes this jump in CPU usage. BTW, one time I deleted the current version of WSJT-X and installed a previous version but still had the same problem so I went back to the current version 2.1.2. I will check out the link you provided. I guess I could re-install Windows. WSJT-X worked flawlessly for years on the same laptop computer. But, with my easy workaround, I'd rather keep doing that instead of taking drastic measures. 73, Steve KS3K |

Hi Steve, no, I know the diff., and I mean to actually go in & shut down Windows Explorer! Using the "services" app from the startup window. Please understand, I am talking about Windows INTERNET Explorer (the web browser), NOT the File Explorer (which used to be called Windows Explorer way back when!) I have mine completely shut off & disabled since I always use Chrome. (Well, at least 99.98% of the time!) In doing so, you'll free up many, many, many MB of memory & your CPU usage will be much less too. Now, I've seen your posts on here now for days; and I am starting to think that somehow you downloaded a corrupted version of the WSJT-X software, or it didn't install correctly, etc. You at some point, may want to start completely over by uninstalling wsjt-x & whatever else you recently installed. Then go back out to the official wsjt-x website & redownload ver 2.1.2 from scratch & reinstall it. Good luck. 73 - John - N7GHZ On Sun, Mar 29, 2020, 8:37 AM Steve Ikler <ks3k@...> wrote: On Sat, Mar 28, 2020 at 10:48 PM, JP Tucson, AZ wrote: |

John, Windows Explorer is not the same as the now obsolete Windows Internet Explorer. Windows Explorer is the name MS use for the Windows Desktop. If you stop Windows Explorer you will not be able to interact with Windows, but you can't stop it anyway since it will automatically restart. 73 |

Yup Bill, you are correct, another MS bad habit, reusing names & renaming stuff; confusing the crap out of people. That IS why I specifically made it a point to underline the WEB BROWSER as what I was talking about, because some people still use it or at least the term. 73 - John - N7GHZ On Sun, Mar 29, 2020, 9:38 AM Bill Somerville <g4wjs@...> wrote:

Ah yes, Gwen, "ExploDer" is right! When half the time, no matter how hard to try, your carefully coded webpage would not render as intended, but was fine on everything else. For the record, I really do miss Netscape 4.7! That thing was so stable and got everything right, until some fool started using non-standard HTML garbage (Bill Gate's 'team').
