Well, there's nothing like shutting the door for a few hours and just getting stuck into it. I figured out a few things... like SparkSDR's LNA adjustment is called RF Gain. So much for applying old hybrid rig understanding! Turns out I had it set lower than needed to cause the LEDs to flash, so I don't think it was clipping, Steve, at least not on SparkSDR. OpenHDSDR was higher, but not really triggering the right LED much at all. So after messing about a little with that, I eventually confirmed that SparkSDR seems to work properly and produce a clean signal. OpenHDSDR... not so much.
Further to Ron's comments, I did my best to set both SparkSDR and OpenHDSDR to comparable settings. But I admit to not having much luck finding my way through the settings, meaning OpenHDSDR and I don't want to play nicely, so.... I decided to add more variables and install Thetis with the latest beta changes I saw posted here a few days ago.
Yeah.... I think OpenHDSDR is getting punted off this computer... Thetis is so far doing everything it should, once I got my head around some of the details (documentation is really good). Signal is clean, although I do hear a noise on the second radio that sounds like the squelch activating on 2 meter FM. Just a very short blast of static after I hear the relay snap and then the FT8 tones begin. Not yet sure how local that is, however.
The waterfall is clean, but that might be due to how Thetis monitors the signal. I haven't dug deep enough to figure out whether it's showing the TX signal or the RX signal, but.... out of sight, out of mind? ;-)
I have not yet found a setting in Thetis that will get the two righthand LEDs lit or flashing though. More digging I guess, unless someone knows a quick way to make this happen? I'm getting a signal out though, as PSKReporter spotted me about as I would expect for 5 watts and a dipole. Made a couple of contacts too, so I'm hearing something...

VAC is developed by Eugene (Evgenii) Muzychenko, an independent software developer.
CheersHello Reid,
Please look up my post on the N2ADR groups io. I described and addressed this issue a long time back.
Basically most hams use the FREE version not realising that it is only ONE cable.
SO, when you go to TX that SAME cable that has been used for receive is REVERSED for TX. Unfortunately, the cable still has RX data in the cable. This 'data' is flushed out of the cable at the start of the TX sequence.
You have to BUY the TWO cables to do TX and RX without corruption. You can get this product from the same VB Audio designer.
Regards
Ed GM3SBC

Hi Reid,
The Windows bar at the top reads Thetis-HL2 v2.8.12 (03/21/21) Beta 2.
Switching mode in RX2 to CW, the paddle triggers TX and Thetis shows power output.
There are times when I've seen VFO B go to dulled colours and not allow user input. I haven't been able to figure out what eventually brings it back (sometimes corrects without restarting Thetis).
I've noted that sometimes after going into the configurations of WSJT-X and Thetis to confirm a setting (cancel to exit), VAC 2 is off. Switching back on does NOT bring back the stream in WSJT-X. The only solution at that point is to shut down Thetis and restart. At one point while searching through the settings, Thetis actually crashed - just disappeared off the screen without any error messages.

Hi Reid,
Back to it this evening... and again, no TX with WSJT-X! Hmmm.... No configuration changes at all since it began working. I tuned around, flipped between bands, called CQ on CW... then tried the tune function in both WSJT-X and Thetis. Nothing.
An interesting thing though... the Tune button on both Thetis and WSJT-X *will* cause power output when TX set to VFO B and RX2 mode set for DIGU, but NOT if RX1 mode is set for CWL or CWU! Other RX1 modes, apparently no issue, but the CW modes in RX1 seem to prevent RX2 DIGU power output.
I also note that switching from CWU to DIGU in RX1 will turn off both VAC1 and VAC2.
