I suggest you use Split set as Rig. Then you won’t have to worry about where you land. The software takes care of it. It uses VFO A for RX and VFO B for TX. Just let the software handle the radio. Bob

Later models have that resolved. Bob, K4TAX

Are you by chance running any other software or running WSJT-X via another application? I've seen cases where closing an application does not release certain parameters with other radios. 73 Bob, K4TA

I've experienced several ham applications that do not exit cleanly. Some may not release a COM port, while others may not release CAT control. I always stress to be sure and close the program correctl

As to time servers, I've not found Windows 10 system for time to be satisfactory. I've installed and use Meinberg NTP. Works great and I don't find that Windows updates to disable the service. Just be

The Time.IS App only compares one’s computer clock to a time standard. My iPhone just compared as 0.044 seconds fast. It does not correct computer settings. I use Meinberg NTP to maintain computer clo

Interesting regarding HRD. I use a single USB cable between my radio and my computer to operate AFSK, PSK-31 and CW. Two of these are audio modes and CAT control. All at the same time too. Bob, K4TAX

This week I encountered an issue with our church Mac that was updated this week with Big Sur. I had to replace or update several drivers in order for the video hardware to to resume working. Good thin

Yes but as Jim K9YC stated elsewhere; "A choke at the antenna feedpoint forces near zero current there, but the feedline may still [be] connected (as common mode element) via the tuner to ground. A ch

This looks like the one I used to get when I had an RFI problem. Reduce power 50% and see if it doesn’t happen again. Most likely a common mode issue. Put common mode chokes on each feed line at the s

Check your computer clock. Maybe too far off Bob, K4TAX

I’d say you have an RFI issue. Put some common mode choke on your feed line. And maybe a ferrite bead or two on the lines at the computer. Bob, K4TAX

The software does a great job in terms of timing. Also, it deals very efficiently with QRM from adjacent stations. What is unknown is how your radio AGC deals with strong signals. What I find in a cro

I am using my K3S and my Down East Microwave transverters on 2M and 70cm while running WSJT-X. Works great. Be advised that frequency stability becomes much more critical, especially with the transver

I find in removing programs, including WSJT and others, that fragments of code are leftover from the previous install. Then when one installs the program again, these fragments, usually broken code, c

Gosh! I have the latest MS update for Windows 10 Pro 64 bit, running on an HP EliteBook 6930P, and have not suffered any of these issues. Wonder why? I'd suspect non-MS drivers being used, or those wo

What method or type of interface are you using between the computer and the radio? In best practice, if the radio has provision for a line-level input, that should be used. My recommendation is to con

Also check mic privacy settings in the Sound menu. I found after installing a new ham application that WSJT was not getting RX audio. 73 Bob, K4TAX

Could be....... but if you have used any other application to play music or video, those applications may change the levels and may change the soundcard choice. And they may not reset them once they a

I agree with Rick. Proper application closure at the end of the day or session and proper computer shut-down procedure is likely key to many problems. Additionally, I've found that some applications d
