Is this some sort of distortion?

There is something else wrong.

Those spikes are not all that strong PLUS you have room for 100 signals in-between each of them. Reason for no decoding is, I don't see any signals to decode! Joe WB9SBD On 10/9/2020 4:22 PM, Joe KN5Y via

Re: Windows 10 app Vol Device Prefences slider grayed out
JP Tucson, AZ
Hi Ted, Wish I had of heard about your usb hub earlier! ...and your fix may only be temporary! Usb hubs have a nasty habit of interfering with wsjtx & soundcards; as they can have power shut downs with power save modes! (Even if you turn off your power save) And like the audio settings, windows can reassign stuff causing loss of contact with the hub. I know SignaLink, for example, specifically states not to use usb hubs because of these issues. If your problem starts up again, that usb hub is your first likely suspect! Just remove it & connect your usb cable directly to see if it works properly. 73 - John - N7GHZ On Fri, Oct 9, 2020, 9:17 AM teka920 <ted.g7obf@...> wrote: Thanks everbody - now got WSJT working |

The answer to my orginal question about the grayed out slider in Windows 10 settings appears to be that it is of no significance and that others have the same. To get my setup working I have

Bill -
What Qt versions are you using? I could probably dig through the repo but if you know off the top of your head that would be great. I'm not aware of a Win7 SP1 dependency but will check with my staff later today. https://doc.qt.io/qt-5/supported-platforms.html 73, Mike - N8MSA |

Hi Marcus, You may have at some stage defined those additional frequencies yourself or got those from an older wjts-x version as in the latest version v2.3.0-rc1 those are not / no more defined for FT8. After Reset only 7.074 and 14.074 are there. 73 Reino OH3mA
From: main@WSJTX.groups.io [mailto:main@WSJTX.groups.io] On Behalf Of HB9BRJ
The default frequency list contains 2 FT8 frequencies on 40m and 20m: 7.071 and 7.074 on 40m, 14.071 and 14.074 on 20m. Several times I called CQ on an "alternate" channel but no response. In an ideal world, one would expect that users who cannot get through the QRM on the main channel would QSY to the alternate channel. |

Nevada QSO Party use of FT8/4
The Nevada QSO party will be using FT8 and FT4. They will be operating about 4 kHz up from the regular frequencies and will be using the Field Day overlay. The out of state exchange will be '1A SECTION' and the instate will be a 'coded number/letter NV' The coded number will represent the county or countyline operations in Nevada. You will have to use the Field Day overlay in order to complete a contact with a Nevada station. For those using N1MM+ logger to work the contest, you will have to exit N1MM and then start WSJT-X and use the logger in WSJT-X to record your contacts and you will end up having to send in 2 logs for your entry. Complete rules, FAQs, and a special section on the FT8/4 operation is available on the website, http://nvqso.com/
Come join us and have some FUN! Jim W6US |

They actually did document it in 2017. I am sorting through the documents now to find the exact one. I have stuff going all the say back prior to version 1.4, so it's a long search manually. It's there, because we used the document extensively in 2017. Give me time, I will fine it in the archives.

Running low power and having only a vertical antenna, I realized many months ago that my QSO rate is significantly higher in FT4 than in FT8, despite the few dB difference in sensitivity. 73, Markus HB9BRJ |

Hi Jeff and all,

The specification does not call any separation at all. The trick is a careful decoded signals reconstruction, QSB estimation and subtraction of decoded signals. Then a new decoding of the remaining signals is possible and quite often successful. Using slit i.e .not calling on the frequency of a CQing station is usually a better as on that frequency there may be too many stations overlapping. 73, Reino OH3mA -----Original Message-----

Noticed that the waterfall doesn't fall..stays blank The pop up screen at the start cannot be stopped popping up at load time I'm not seeing any rx levels on the LH pane when using WSPR mode so not sure if anything is I guess these may be only happening to me as its not the most powerful of tablets but would be good for trips out of the home QTH 73's Neil G1ABR |

Hi Bill - says file not found ...still strange that error message only appears when I download the 64 bit version of WSJT, no message on 32 bit version ?Hi Jay, looks like it may be a Qt Framework error. The 64-bit version of WSJT-X uses a newer version of the Qt framework we use for cross platform facilities and portability. The Qt versions we use both support Windows 7 or newer, 32- and 64-bit versions of WSJT-X should work the same. All I can suggest is trying again with the 64-bit version for the next WSJT-X v2.3.0 release when it becomes available. 73 Bill G4WJS. |
