Re: Audio volume level passed to apps lower than expected
Frank O'Donnell K6FOD
Thanks, Tony. I see that when I have AGC off, the gain slider in that section had been set to minimum. Moving that slider up and down doesn't affect the RF signal level as seen in the waterfall or dBm meter. However, it does significantly affect the audio output level, and by moving it up I get a strong input level in the apps receiving audio from SDR Console. So problem solved -- thanks again!
Just so I understand this, am I right in thinking that the AGC slider acts at the IF stage? Thus it doesn't affect RF levels reported, but will affect the audio output since that's downstream? Also -- it appears that it doesn't affect levels as recorded in I/Q .wav files, which I gather are taken before the IF stage? Frank

Sorry, I meant the gain slider. Slope and threshold are only visible with AGC on. With it off you get a gain slider.

When you have AGC off, there are sliders in the AGC section that you use to adjust the gain. To the right of the AGC buttons is an icon to click for the sliders and another for the graph. Adjust the slope and threshold sliders to get the level
you want.

Thanks, Dale, good ideas. In my case, noise reduction is not enabled.
As for the equalizer, it's set with each of the vertical sliders at mid-range so the graphic shows all of them at zero (neither + nor -). I see the equalizer's checkbox to enable it is not ticked. I assume this is all the default, as I've never played with it. Do you think the settings as shown in your screen print are more effective?

Re: HL2 Portable - Proof of concept UPDATE
Just about ready to assemble it all.
The Arduino MIDI controller handles frequency changes (VFO), VFO "step ranges" up and down, AF Gain, Mute Toggle, DSP Filter lower limit, DSP Filter upper limit, Mode & Band selection, RX Panel Display Toggle, TX Panel Display Toggle, TUNE and MOX functions. The 5" capacitive touchscreen display works very well (even with my stubby fingers but MUCH better with a stylus), and there is virtually no lag. CPU burden ranges from 9.0% - 20%. I am still messing with audio outputs (I'd like to use a bluetooth headset but so far can only get RX audio out), but I have a small 5w AF amplifier sending audio to a Visiton FR7 high quality speaker - sounds great! Will be built into a smaller Takachi cabinet. I will post pix as I move along.

Audio volume level passed to apps lower than expected
Frank O'Donnell K6FOD
This week I've been using SDR Console v3.1 to pass audio output via Muzychenko's Virtual Audio Cable software to various apps. The PC is running Windows 10 Pro build 19043.
The levels I'm seeing, even when all controls are maximized, are a good bit lower than I'm remembering when working with comparable signals in this way a few months ago. The apps include audio editors such as Audacity and GoldWave, as well as WSJT-X. So far I've checked: -- In SDR Console, the output level slider (in the lefthand pane just below the output device selection and RX frequency) is maximized. -- In Windows' Sound settings, Line 1 (Virtual Audio Cable) is selected as input, with volume set to maximum. -- For those apps that have an input sound control, level is maximized. Is there anything else worth checking? Virtual Audio Cable has a checkbox to enable volume control, but the control itself doesn't appear in the VAC control panel. I gather this would be the volume control within Windows' Sound menu? Thanks for any possible ideas,

My information on QRZ.COM is three house moves and 30 years out of date. Plus the kids were a lot younger then, pre-teenage so still welcome in the home… I would update it but I’m still wading through domestic stuff and refiling. My shredder is a great source of QRM I’ve discovered…
