Unusual problem with FT8

Randy Member ✭✭
edited March 2020 in SmartSDR for Windows
Having problems using WSJTX's FT8.  Works fine on 20 meters, but will not work on 40 meters or 80 meters.  Have not tried on any other band.  Had initial problems which were solved by reinstalling DAX drivers.  I could then work 20, 40, and 80 meters.  Now I can only work 20 meters. FT8 shows no band activity.  Reloaded WSJTX and reloaded Smart SDR v2.0.19.98 and still 20 meters is all that will work.  Any ideas?

    Check yo make sure you're using USB or DIGU on all bands.

    Be sure  your DAX is selected so it is not "none"

    Working now.  I thought you would use DIGL on 40 and 80.

    I had the same problem today and reloaded the DAX drivers, now is working fine again. Must have been a W10 update? I followed the instructions here: https://helpdesk.flexradio.com/hc/en-us/articles/204017069-How-to-Manually-Re-Install-DAX-Drivers Sometimes a SSDR reload doesn’t reload the drivers, depending on how you proceed. Hope that helps, 73 Justin KL2D
