To close out the saga, I hooked everything up in its original configuration including all three Ethernet switches. Without firewall it is rock-solid, with the firewall, it's unstable as before.
Thanks to everyone,

Re: VAC & ASIO Under/Overflows
Surprising result... My hypothesis said that the three network switches inline from Angelia to Thetis were introducing instability that caused over/underflows in the audio stream. This despite GPS-disciplined synchronization for the time domains at each end. To test the hypothesis, I set up the foll...

Re: VAC & ASIO Under/Overflows
Scott - Thanks for explaining. I wasn't sure which control panel was intended. I had set everything to 16-bit/48000 long ago as per your tutorial.

Re: VAC & ASIO Under/Overflows
KC2RGW... could you elaborate a bit on "Also double check Control Panel and set all the busses to 48k 24 bit if you haven’t." I'm not especially fluent with Voicemeeter.

Re: VAC & ASIO Under/Overflows
Scott - regarding your question, "Why are you not routing the Thetis virtual channel to both the WSJT-X and Map65 channels?" Map65 gets its I/Q feed from a UADC4 via Linrad and the network.

Re: VAC & ASIO Under/Overflows
Here are my Thetis settings. This instance has been running for an hour or so and has settlled down nicely after the first five minute of thrashing.
I will examine my VM setup in the morning; thank you for your observations and comments.

Re: VAC & ASIO Under/Overflows
Scott, sorry, my wording was poor. I know to always keep the main buffer in Thetis the same as in the ASIO driver. I meant that the main buffer had to be big in order for the VAC loop to be reasonably stable. After a number of warm and cold starts, stability is elusive. Sometimes VAC settles down in...

Re: VAC & ASIO Under/Overflows
I posted too soon... After a couple of hours, the Over/Underflows converged to zero. A restart (with Audio/Advanced/Old VAR checked) resulted in only a few glitches at first, followed by settling to zero within 5 minutes. Maybe my initial instability was due to an obsolete VAR from pre-Presonus?

Dear friends, After reading the "Thetis 2.8.11-21+++ VAC advanced controls: results and discussion" thread a couple of times, I purchased a Presonus 192 Mobile USB audio interface in the hope that it would be more stable than my previous Behringer UMC204HD. I hooked up a Leo Bodnar GPSDO @...

Turn off AGC altogether?
Dear friends,
Is it possible to turn off AGC altogether in Thetis? I do EME and it is useful to measure signal levels at audio where AGC just gets in the way. Note: I'm not asking about turning off "auto AGC gain mode" (which is so redundant.)
Thanks,
W9IP

Re: Thetis 2.9.0.6, ASIO, and VM Potato with WSJT-X & Map65
As usual, your explanation and suggestions were spot on. Thank you for taking the time to reply. I now have WSJT-X and Map65 routed through Voicemeeter and then to Thetis. The second part (Voicemeeter-Thetis) is ASIO which is exactly what I needed to do.
Thanks!

Surprisingly, 150% works OK; it's just 125% font enlargement that causes Thetis to crash on start-up under Windows 7. Weird.

Re: Font size and Thetis crash
I don't see any options for font size in Thetis either. That wasn't my original complaint, however. I had changed font size in Windows 7 and now Thetis won't launch. Scott... Yes, Thetis seems to run fine on Windows 10 with enlarged Windows fonts. It's Windows 7 that is the problem.

How does the RX attenuator work?
Dear friends, I am having trouble understanding how the drop-down RX attenuator works. I would expect that adding attenuation would lower RX levels; this is how an external (physical) attenuator works. You add a 10 dB attenuator to the RX input and all received signals are reduced by 10 dB. In Theti...

Re: Thetis: RX1 & RX2 without diversity?
When playing with Setup/General/ADC as suggested, I find that only Protocol 1 ADC assignments have any effect. Protocol 2 assignments, nothing. I'm running Thetis v2.8.11 (10/20/20) and an Angelia board with v. 5.4 firmware which I believe is Protocol 2. Am I overlooking something?
