#1 is likely one of two things...time sync...or sound card dropouts. Time sync
is easy to check at http://time.is. Sound card dropouts are harder but would
be visible in a saved WAV file (see Save/Save All menu). And provide us with
an example WAV file that doesn't decode as you think it should.
#2 You should test connecting WSJT-X directly to the FT-991 and see if it
behaves better to remove HRD as a potential problem.

I am currently running: WSJT-X v1.8.0 r8193 on Windows 10. I am using a MFJ
1204 USB Radio Interface for my sound card, it is linked to my PC and my Yaesu
FT 991. I use Ham Radio Deluxe (6.4.0.794) and have that selected as my “Rig”.
I control the receive and transmit volume through the MFJ 1204. I am very
careful to keep the receive (mic) at around 50 dB on the bar graph. When I
transmit I ensure my ALC meter does not register at all on any outgoing
transmissions.
I do have multiple options for sound on my PC due to external speakers but my
MFJ 1204 is selected in the “Settings” for both Input and Output for WSJT-X.
(same settings I use in my HRD software)
There have been two main issues that happen spuraticly. I have not been able
to nail down the causes as of yet.
- There are times when I first start up my pc and WSJT-X that it will only
decode one or two signals at a time when there are dozens of signals. My
filter width is set to 3000Hz. ( I never change this). The only way I have
found to get WSJT-X to work correctly is to uninstall the sound card drivers
and re-install them. Sometimes it take a couple of try’s of uninstalling and
re-installing to get it to work. This does not happen every time I start up,
but about one in every four.
- There are times that when making a contact that my PPT does not release at
the end of the 15 seconds. It will continue showing I am transmitting up to
5-6 seconds into the next transmission cycle. My transmission of data will
end before my 15 seconds are complete but WSJT-X will not receive data until it
has release my PPT. I frequently miss the replay message from my contact.
This seems to happen on specific contacts, and across different bands. I can
then click on a different contact in the same band immediately afterwards and
it will work fine., but if I go back the previous contact it will happen again.
I does seem to happen more when the contact is closer to actual frequency I
have dialed in and less when I get farther down the band width.
If you need any more details I would be happy to respond.
I do love the software and the FT8 language.
