Omnirig Qlog disconnecting from Rig

[foldynl]

Discussed in #831

^{Originally posted by jasonamorrow November 11, 2025}
I often leave Qlog version 0.46.2 running on Windows 11 25H2 for long periods of time and Qlog will disconnect from my ICOM 7300 via Omnirig v1 and display the following warning.

Manually selecting Equipment -> Connect Rig will reconnect the rig and everything works as expected until it disconnects again. I haven't noticed a consistent reoccurring time period related to the disconnects. The serial connection is fine and other programs running at the same time like WSJTX using Omnirig do not disconnect and display an error. Is there any way to prevent this from happening?

Here are the debug logs from just before and after a disconnect.

I am/was having disconnects as well. Increased timeout in omnirig a bit. Currently 3 pieces of software are querying omnirig. So I am guessing it's just contention at least in my case.

[foldynl]

I prepared some changes, but I’m not sure whether they will help. I have the same test environment as you (Win + IC7300), but I was never able to reproduce a timeout from the rig. Hopefully this will help.

[ValtsS]

I think it will improve things. I see WSTJX to lose connection to Omnirig sometimes, but its a rare occasion.

As for reproducing, few days ago I realized it's quite easy - need just enough clients writing to the the same Rig. I can trigger the timeout immediately if I have:

• wsjtx running
• qlog running
• and https://github.com/ValtsS/OmniPTT/blob/31f96cb14e179dfc4aba343caaf8ee25c7e38732/Unit1.pas#L199 this code being run every 5 seconds

QLog will show disconnected error immediately after the NR is disabled;

P.S. I have FT DX10
