3.0.26 audio problems

Edited


Hello
(1)Many times after using the Binaural mode and returning back to the standard AM mode the audio levels lowers by between 3 and 6 db levels
Does it happen to anyone also?  
(2)αudio has many cracks since the version 3.014  and stills continues to happen in the V26 Look carefully this video for more https://youtu.be/-WmR60it5H4  that is made with external program . These cracks are not heard with the internal grabber
AND  another video https://youtu.be/GQhXGEoMtAg

Thanks,

 

Maybe just a lot more buffering, try the x4 option?

Hi Joanne

Might not be expensive but I have some Behringer kit (UMC202HD for used mostly as mic preamp) and have found it excellent. I guess experiences may differ.

I'm transmitting at 100W on the IC-746 and no it doesn't have a monitor.  As I don't need to monitor the sdr when I'm transmitting I thought my idea would work. i.e. it will clamp the sdr input when I'm transmitting.

Well, It appears that the problem has fixed itself...ghosts in the machine !

Here's what I did/happened since I sent the last files to you Simon:
1. Disconnected the Behringer and threw it to one side
2. Re-enabled a couple of the standard PC Audio (Realtek) components, namely 'Stereo Mix - Realtek high definition Audio' & 'Microphone Realtek high definition audio'
3. Made up a lead to take the Audio Out from the PC/Realtek to the Monitor Speakers directly
4. Plugged monitor speaker into PC/Realtek, Realtek driver asked what I had just plugged in, confirmed 'speaker out'
5. Made Realtek the default 'Output' Device
6. Tested SDR Console all good

When you requested the log file, I reversed all of the above, namely re-disabling the Realtek components in Point 2, removing all extra leads, plugged Behringer back into the Same USB port as used previously,
made Behringer the default 'Output' device. Started SDR Console and now audio is perfect using the Behringer.
Additionally both the CPU Load & Audio playback buffer values are much lower - CPU: 17.7% Audio: 29ms when using the Behringer

No re-boots or other activities, other than closing SDR Console when not in use.

Probably not of much use to you now but latest Behringer screenshot & logfile attached. Wish I'd captured the previous logs now !

Thanks

Simon,

Just to clarify, using the standard PC audio Device (Realtek) everything works 100%. When I referred to horrible audio using the standard PC audio it was the low quality speakers internal in the All in one pc that are the problem there, definitely not a SDR Console problem.

I have tried recording via the SDR Console recording tab, the problem with that is regardless of the recording device selected in Windows Sound settings the recording all come out 100% OK.
Note quite the quality you probably need but attached is an MP3 that sort of demonstrates the problem with the Behringer audio, The only way I could capture this was to use a dynamic Mic held up to one of the speakers and record via Audacity. However, the recording doesn't quite demonstrate the problem  as each application I open (for example Audacity to record the file) increases the CPU Load which appears to reduce the Audio Playback Buffer value in SDR Console thus correcting the warbling problem.
The more the CPU load the less the buffer value in ms !

With the problematic Behringer Sound Device, CPU usage is about 15-20%, Audio Playback Buffer Value around 500ms
With the Realtek, CPU usage 20-25%, Audio Playback Buffer Value around 85ms

I've attached the 2nd screenshot from my previous post which i the one for the standard PC audio device (Realtek).

I assume you want to connect to my PC ? Teamviewer or such like ?

746, I believe. I don't have a manual for it to check the schematic. If you do, chime in if it has a monitor receiver output.

Re: FT8 checking my signal

The diode fix would be good if you do not have nearby high power transmitters. If you do have nearby high power transmitters "diodes do as diodes are." They can cause IMD problems on overload.

And, on this you can probably trust me thoroughly. We are talking about minimum signals well beneath one microvolt, -107 dBm. We are dealing with transmitters perhaps +50 dBm. That's nearly 150 dB of attenuation before your signal reception at your site will become unsuited for what you want. You have no idea how hard it is to get an honest 100 dB in a screen room within a screened facility (floating on a bed of mercury.) (That's the old Rockwell International calibration lab in their Anaheim campus.) We designed for 120 dB isolation between input and output of the GPS satellite frequency synthesizer. We figured we could "fudge" and make 80 dB just about work to bury the oscillator's version of 10.23 MHz in the noise sidebands from the oscillator. We managed 100 dB. This is on Phase IIa. On the next satellite set built they tried to take out some of the ceramic PCB to hogged out alumin(i)um box grounding wires. They could not take out even one of them and maintain enough isolation. This is with a solid lump of aluminum with a +/- 2 Hz synthesizer in about 2 micro Hz steps on the output and a stable but maybe off frequency Cs standard. (They actually did end up using that synthesized that way. It was designed to corrupt the GPS signal "so the soviets could not plunk a nuke down Jimmy Carter's toity" ((C) jdow) using our GPS.)

Betcha you can hear yourself on 20 meters just fine. You may hear yourself too well as a matter of fact.

in program options/start you may find an option to increase "priority to above normal" to reduce interruptions

did you try that?!?

Good evening group.

I've just installed SDR Console V3.0.26 64-Bit with the hope of using it in conjunction with a Pluto (on its way to me) to access QO-100.

But, I have a problem, when familiarising myself with the software using an RTL Dongle and listening to BC-FM the receive audio is very wobbly and occasionally drops out for a ms or two.
I have gone through all of the setup items and the audio buffer settings do make a very slight difference but the 'wobbling' persists.

When researching trying to find answers I did notice though that the more tabs I opened in my browser the better the audio got !
This translates to a higher CPU Load and a Lower Audio Playback Buffer Value, as displayed on the SDR Console taskbar.
Obviously artificially increasing the CPU load is not the real answer.

Any tips or Hints as to where I can look next ?

BTW, My shack PC is a Intel Core i3 with Windows 10 64-Bit and comfortably runs my Anan 100D via Thetis or PowerSDR. Also the RTL_Dongle works perfectly with SDR #.

Thanks,
Peter.....

The sdr setup is independent of the transmitter.  The transmitter and associated outdoor antenna is separate to the sdr receiver and indoor loop.  It turns out my solution could be simple, a couple of diodes across the sdr antenna input.  See here http://www.kk5jy.net/rf-clipper/  Although I won't be able to see my transmission if I do I can use a temporary attenuator as you suggested earlier.  At least the sdr should be protected and I should be able to use the sdr as a pan adaptor.

Re: FT8 checking my signal

Where is the SDR patched into your setup. Are you using it as an IF spectrum device or are you using it as if it was a separate device on your antenna. If it is tapped off the transceiver's first IF then you should be safe. If you are on an RF output designed for a second receiver it is probably OK. If it is on the antenna used for transmit, a really high quality RF relay that disconnects and shorts the receiver input when transmitting is called for.

settings->System->Power and Sleep
On the far right under "Related settings" click on "Additional power settings." Show additional plans". Select High Performance.

Or.... here are two bat files I use.
===8<--- MaxPerf.bat
@powercfg /S 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
===8<---
===8<--- BalPerf.bat
@powercfg /S 381b4222-f694-41f0-9685-ff5bb260df2e
===8<---

With task manager you can see the effects the two commands produce. Unfortunately much of what is going on here is hidden by Microsoft's GUIDs for the two power modes. And I am not even sure they will be the same on your system as mine because I forget where I got this.

There may be better information on Google. The GUI is a way of making it more understandable. You select a power plan. High performance nominally is "pedal to the metal." Balanced performance is fine for most things including youtube. Power saver might be the way to go for reading mail and the like if power saving is important to you.

Windows 10 Advanced Power settings. From your description of "internal speakers" I would guess this means it's a laptop? They often have power settings set to conserve battery power by restricting the CPU power. May be this? As far as I know this is where it's set. See attached picture. Or there may just be a preset power plan in the top drop-down for "Maximum performance".
