Gary,
Look at the main GUI, button marked "Lookup" just above the Date and time window.



From the User Guide:
"The program can maintain a database of callsigns and locators for future reference. Click Add to insert the present call and locator in the database; click Lookup to retrieve the locator for a previously stored call. This feature is mainly useful for situations in which the number of active stations is modest and reasonably stable, such as EME (Earth-Moon-Earth) communication. The callsign file name is CALL3.TXT."

The button might not do what you want, but "Lookup" is prominently there!
Kind regards
Kai, KE4PT

It would seem possible to add a feature to FT8 that would allow users to list a particular call they were looking for (such as a DXpedition) and have an alert sent when that call appeared in the FT8 "calling/working" list. Has anything like that been discussed? Thanks!

Perhaps the reason is they are still working on the bugs and enhancements of the primary package they have now.

WSJT-X doesn’t have a lookup button and never has that I know of. The program is more than a little busy to want to add something that might have to wait on the extremely variable speed of the internet.

I live in the Pacific NW and propagation on all bands has been dismal for the last several years. I like working DX on any band and mode so FT8 has been a new challenge for me.

Recently I switched over to FT4 to see what is out there to work. I found that the activity level is considerably lower on the two primary bands I operate, 40 and 20 meters. My big discovery is that I have made many contacts on FT4 that most likely would no be possible with FT8. My observation is that there are very brief openings ranging from 30 seconds to 3 minutes where DX to Europe and other distant locations occur. Contacts using FT8 with these brief openings are usually not possible but FT4 works quite well.

I have chased a lot of DX on 160 m using CW and am used to waiting 20 minutes for a 30 second QSB peak to occur to work a DX station. These peaks are very similar to those I have seen on 40 and 20 m and FT4 seems to be the mode that can take advantage of them. I'd expect the same to be true on 6M where sporadic E and meteor bursts provide paths of short duration's.   

I would like to see more DX stations to try FT4 on 40 and 20 m to see if FT4 maybe the more desirable mode for DX on some HF bands and conditions. One of the advantages of WSJT is that one can watch the waterfall to see the DX station before a decode happens so timing an attempt for a contact can be optimized. 

Hope to work you soon on FT4!

I have looked and it appears that the callsign lookup button really doesn't do anything, unless another application is also installed, like JT-alert.
Why not add some options, for lookup sites like Hamcall, QRZ, (for the paying subscribers) or HamQTH?

Hi Paul,

I have not used HDSDR in a very long time, but I think you need to examine the configuration of I/Q on "Input Channel Mode for RX"

Hi I am hoping someone can help.

 

I have been running wsjtx with various modes using the following rig combination.

 

wsjtx ---> HDSDR ---> softrock The link between wsjtx uses VAC cables for audio and CAT to HDSDR for rig control.

 

This combination worked fine for many years (since 2016) on a PC running W7 with many 100s of contacts.

Unfortunately having recently replaced my W7 PC with one running W10 it no longer works.

I have traced the problem to the fact that somewhere in the chain the allocation of the I/Q signals to the L/R audio channels gets swopped.

 

Now the reason for asking help from this group is that I do not see the same problem when going from W7 to W10 with other software combinations

eg Powersdr v2.4.4, fldigi ---> quisk

 

I know that this is an unusual setup but I would be interested if anyone else using a similar system has experienced problems.

FWIW .. it will always create a .wav file each decode cycle to enable any debugging, but will always erase it.   HOWEVER ... if you close the program in the middle of a decode cycle, that file WILL NOT be deleted.    That is why under the FILE menu there is a selection to DELETE all files in the save directory.     The developers advise to use that at least once a month (or more often if necessary) to clear out that directory.

It appears to be working now. I had to go in and manually erase the existing files. Then when I started WSJTX with no wav files it deletes the new file after each receive period.  Should have tried that before posting.

Hey Walter,

Thanks but that is what I have done and they are still being saved. At least there is apparently a limit of 2611 files because the oldest is erased before the new one is saved.

 Try clicking on the SAVE then select NONE.

How do I turn them off?

I have gone to the SAVE menu and have NONE checked but the wav files continue to pile up in the save directory.

Hi Paul,

in HDSDR on the Options menu (F7) you can select swapped I and Q channel assignments for Rx for sound card I/Q data.

That is why the wsjt-x webpage recommends you to install Meinberg NTP or equiv if you are on Windows.

Yesterday I opened WSJT-X and had the same problem with no FT8 decodes. I checked my computer clock and it was a full 4 seconds ahead!

After synchronization, everything is back to normal. I wonder if leap day on February 29 could have been a factor.

Windows 10 does have an easy synchronization feature. Go to Settings, Time & Language, Synchronize Your Clock, and Sync Now.

How do I turn them off?

I have gone to the SAVE menu and have NONE checked but the wav files continue to pile up in the save directory.

I also use Windows Defender on the computer running wsjt-x. I set it not to scan wsjt-x's audio directory.
