played a bit more this morning, something is still wrong with the "attenuator on TX". Goes to zero after each TX.
I guess this is also related to my power drop since I installed the new software.

2.9.0.8 power output bug
Just noticed after installing the latest one and running my Anan200Dat 25 watts and Pure signal, after a few minutes of QSO the power drops. I guess related to the attenuator the Japanese ham mentioned a few posts back. Restarting all gets it running again for a short time. Refolding to my other lap...

Re: VAC Tutorial
My Thetis audio was fine since I was running voicemeeter as you suggested. Recently it stopped working and I have no idea any more what went wrong. No more audio via ASIO... Did not change a thing. No more audio to or from Voicemeeter from Thetis. Can hear my own audio in voicemeeter. classic VAC wo...

Re: white noise in audio chain reveals modulator issue
Hi Scott, I am doing all tests on my Anan200D. I just mentioned that my friends with Hermes lite have the same dark audio phenomenon with Thetis in the windows directsound settings... I managed to get friture white noise running into the Anan via voicemeeter. All fine. USB micro too, all fine in ASI...

Re: white noise in audio chain reveals modulator issue
slowly getting there. Voice meeter uses ASIO. The audio integration issue is in VAC. ASIO is a totally different way of submitting audio to the radio.

Re: white noise in audio chain reveals modulator issue
Managed to route my audio test generator to thetis via voicemeeter. Now the frequency behaviour is flat but I did discover another bug. The displayed TX spectrum is totally wrong, it even moves... as you can see from the screenshot. Did not do anything and then things turned OK. But to summarize. I ...

Hi scott, tried this voicemeeter thingy but I cannot manage to route the audio from friture to Thetis. Weird program, when I switch its output the virtual input disappears...

Re: white noise in audio chain reveals modulator issue
so the only difference is you two use voice meeter or the Muzy VAC, and I am not. So it must be there. (I guess walter showed the control panel of Muzy VAC ?) will try voicemeeter but I do not like all these additional programs if something is built-in. Voicemeeter is overkill for this application t...

Scott, Walter, thanks for the hints. It is /was never my intention to appear rude but having a totally shitty modulation with a 3000 euro radio renders me desperate...

Re: white noise in audio chain reveals modulator issue
Hello guys, The issue is still there and has been confirmed by other people using Thetis with Hermes boards. WHY is the audio not flat coming from W10. Just tried a new install W10, no audio tweaking whatsoever. Internal Anan white noise is perfect, the VAC audio is going down significantly with inc...

Re: white noise in audio chain reveals modulator issue
Friture can output directly digitally to windows direct sound, so straight into VAC of Thetis. Click on the toolbox in "generator"
Great software not ? I use it to teach my students audio measurements at home during lockdowns.
Not using any equalisers in windows....

Re: white noise in audio chain reveals modulator issue
Great hint, did not know the Thetis had built in white noise. Just tested, perfectly flat !!!

As far as I know all my windows settings if any are flat.
Using windows direct sound.
Any more ideas ?

Re: white noise in audio chain reveals modulator issue
You can see the lines of my TXbandwidth filter. 300 Hz to 2900 Hz.
It is a 50 dB coupler. 30 dB directional coupler and 20 dB attenuator. It does not matter if there is an antenna or not. The thing has great directivity....

Re: white noise in audio chain reveals modulator issue
apparently everybody I speak to noticed this behaviour with their Hermes Lite's etc. They all have a TX spectrum that goes down like hell. Nobody cares, they just put their TX analysers extremely to compensate. To my opinion this is a serious programming bug in the modulator software. It should be f...

Re: white noise in audio chain reveals modulator issue
I am not talking about a few dB.
This is what my TX looks like taken from a -50 dB coupler on the antenna: All settings flat. White noise.

white noise in audio chain reveals modulator issue
Dear colleagues, After getting complaints about dark audio I decided to feed some white noise directly into VAC1. A great freeware program for audio analysis is Friture.org. After doing so it was clear to see that the Anan 200D flat spectrum was absolutely not flat, severely dropping above 1 kHz. Th...

Re: ANAN 200D PA issue (power drop above 20m)
Yes they have effect but I have no idea if a setting of 44 dB on 20 meter is normal or not. Then I get 50W FM and 100W SSB
