ok, so this site HB9RYZ - Swiss Amateur Radio Station - QO-100 - Remote DX-Station Rigi Scheidegg says - the new HDSDR version v2.8 (March 2020) uses the new OmniRig. It also says "However, OmniRig v1.19 and OmnirRig v2.1 can run on the same computer at the same time." That apparently is not true. When I have only the old OmniRig installed (installed last) then the VarAC works fine. But if the new one is installed VarAC uses that. However the latest HDSDR, which I use for my SDR panadapter, uses that. If I cannot find a way to do both then the panadaptor wins out. I won't give up that for VarAC. I try re-installing the old one and then VarAC worked, Then I go try HDSDR and it appears it can still find the new one. SO, THE MORAL OF THE STORY APPEARS TO BE THIS: If you are going to install OmniRig v2 you have to go back and make sure you reinstall OmniRig v1.2 after that.

Yeah, thanks. I thoght I was using all the right versions. Even HDSDR hates V2.

I must have got some new version of OmniRig. After removing it, then going to the actual creator of OmniRig and installing it all over again, & rebooting, I have the old menu items back, and it works. This is now OmniRig v.1.20, and installs to "C:\Program Files (x86)\Afreet\OmniRig" The other one is V2.x

Omni-rig 1.20 (was using this with my FT-450 and SDR, works great for rcv) Vara HF 4.6.2 (just updated) VarAC 4.1.6 Going through a SignaLink, just like I do for VARAHF Winlink (success for years now). Slider does nothing. ALC shows waaaay too high on transmit. Slider is represented in the Vara modem; that works, but does not change ALC. Also, twidling the Windows audio "Playback" for the SignaLink does nothing. WAIT, just now I noticed that the transmit switches to LSB from DATA USB. Looking into that... ... time passes ... Transmit in Winlink (VOX & SignaLink) does not switch to LSB, it just changes from "BUSY" USB & "DATA"-on to "TX" USB & "DATA"-on In VarAC it changes from "BUSY" USB & "DATA"-on to "TX" LSB & "DATA"-off I have the latest Rig ctl settings INI file, and I even made the FT-450 section match the FT-450D (there is one small diff) ... no change though.
