Locked No decode on 40m, Band Activity blank #FT8
|
KG2RG
New to digital, but I’m having an issue on 40m only. There is a lot of signals on 7.077 on the waterfalls but nothing is decoding into the band activity box. Transmit also works fine.
This issue is only on 40m. I have made many contacts and the band activity fills up fast with station traffic. Crazy thing is that 40m is my strongest band with a quality ant. I’ve checked all of the filters and I’m listening 3K wide. |

You should be on USB and dial 7074 kHz. If your receiver is on 7077 LSB, WSJT-X will not decode but the waterfall will look 'normal'. Your bandpass should be about 7074.2 through 7077 kHz. IOW, your receiver should be passing audio tones from ~200 to ~3000 Hz to WSJT-X. Hope this helps, Chuck |

7.077 is where JT65 is or was.

FT8 on 40m is on 7.074. Look there for FT8. Best regards, *Kevin Potter * *k5vp* On Wed, Jul 13, 2022 at 1:42 AM KG2RG <justinandyazny@...> wrote:

Are you correctly set to USB?

I am experiencing the same thing right now. Windows 11, WSJT-X v2.5.4, Yaesu FTDX10. 20 meters (14.074) is fine, 40 meters (7.074) no decoding. It used to work. Set to LSB on 40 meters, USB on 20 meters. I have an ICOM 7300 and I will try it on 40 meters tonight.

this is the solution. if you don't have a dig mode, you MUST set USB also
in 40 and 80 meters. Pietro I2OIM Il giorno mer 13 lug 2022 alle ore 21:09 Larry Banks via groups.io <larryb.w1dyj@...> ha scritto: It is USB everywhere! |

Too many peo-ple are mixing up
USB - Universal Serial Bus USB - Upper SideBand Use USB on all bands for data modes Does no one read the manual - it says it quite clearly in there. *Use UpperSideBand* Andy www.g4jnt.com |

I don't see anywhere that this was suggested. Open WSJT-X. Set operation to 40m. Go to the WSJT-X "MODE" drop down menu. Verify that FT8 has a check next to it.

Second line in section 5 of the WSJT-X User Guide:
Be sure your transceiver is set to USB (or USB Data) mode. 73 -Jim NU0C On Wed, 13 Jul 2022 16:30:13 -0700 "fritz1000 via groups.io" <fritz1000@...> wrote: I don't see anywhere that this was suggested.

One reader of this group sent me an email about FT8 being USB on all bands. I tried USB on 40 meters and decoding started working again. I thought my configuration was broken but as it turns out, my mistake was setting the radio to LSB on 40 meters. I made the mistake of assuming the mode was the same as SSB on that band. The funny thing is I had used FT8 on 40 meters on that radio in the past and it worked, but I had not noticed the radio was in USB mode. Thanks for the help.

I'm seeing a similar kind of problem where WSJT-X (v2.4.0) will stop decoding if the setup is left untouched for a few hours and is only doing Monitoring. It happens regardless of band. At first I thought it might be something funny coming from JTAlert as I only started using it a few days ago, but with only WSJT-X running, it still stops decoding after sitting untouched for a few hours. Signals are on the waterfall and it's falling normally, the cycle timer is running, the DECODE indicator flashes at the right time but nothing shows in the Band Activity window and nothing shows up on JTAlert. If WSJT-X is decoding, it's not releasing the results.
This does not happen if I'm operating fairly regularly for several hours, e.g. it worked without a hitch over Field Day but now, if I leave the computer and radio alone, WSJT-X will stop releasing decodes after a while. It's lilke some user action on the computer is needed to reset a watchdog timer (I've got the TX watchdog set to Disable). Now, I know I'm using an older release of WSJT-X, but it works fine for me and I probably won't be upgrading until 2.6.0 is released. Nevertheless, I think there have been other posts here reporting the same problem with 2.5.0 and maybe also RC2.6. This is NOT a USB/LSB issue. I know what sideband to use for FT4/8. The only way to get things going again is to close WSJT-X and launch it again. Anyone in the know have any ideas? 73, Hugo, ve3ktn. |

When that happens check http://time.is and see if you clock is correct (i.e. the site will say "exact").

Hi Hugo,
There is one known issue at least in older versions of WSJT-X that may be a reason for "non-decoding". Do you have in General tab in the Display section activated the Start new period decodes at top? I have been running WSJT-X without it now almost two years 24/7 and have had no problem. At least earlier the display stopped after an extended period, but the decodes were there and could be seen by rolling the display. I had to erase the display now and then to keep it working. I don't have JTAlert in use, so don't know how it behaves in that situation. 73, Reino OH3mA |

I had the same problem, but it stopped when I upgraded to the latest WSJTX.
