Re: PlutoPlus & SDR Console - Garbled audio

Progress!!! - The "Internal Microphone Array" is working and clear on record so I expect it to be clear to receiving stations.

The Yeti (second MIC tested) only has 2-channel options and is USB connected to a USB hub connected directly to the laptop.

The Logitech headset (original MIC) only has 1-channel options and is USB connected to the laptop docking station.

It looks like USB is the issue - it must be picking up noise there.

I have a USB extension I could try which is shielded pretty well.

Is this audio problem the same for all your microphones?

Good.  This must be a microphone setting, I’ve compared your log to mine and there’s no difference.

 

In the Device properties show me the window (below). I wonder whether there are some special options?

Um, er, it might right there staring him in his face, among all the odd settings. He's about 4 kHz off calibration; his audio is muted so of course he will hear nothing; he has gain set to maximum and video gain set to -30; he is set to full duplex (try simplex, make it work, then try duplex if needed); TX side has gains maxed out (overload can produce odd effects); RF bandwidth is a tad small for WX broadcasts; and I lost interest looking for more. (I have noticed that out of a fairly narrow band of Visual Gain settings the radio will blank. That suggests me Video Gain is not really only a gain for the spectrum related displays.

He should try 12 kHz bandwidth. It will sound better. (He should NEVER try to transmit on that frequency. Never Never Never. I hope he didn't try it.) NOAA broadcasts are a wide NFM rather than the narrower deviation hams and many other services use. Channels are 25 kHz.

Is his antenna connected to RX or TX side? Is he set to use Pluto's AGC? (I don't trust it. Is there a strong signal out of his display range that is suppressing Pluto's gain?)

Is he set to NFM?

Simon, you might do some good to place current mode and IF bandwidth down in the status bar.

Well I decided to update the Pluto firmware to 0.34 - now I am not receiving anything in SDR Console on the Pluto - for comparison I connected a RTLSDR and it's working fine.

 

BTW, the original issue was with TX audio from the Pluto being garbled - RX audio was always fine.  Also when I send the tone it was always fine on the other radio, I was monitoring both it on.

 

Advice on how to proceed?

Hi,

 

  1. PlutoPlus – first time I’ve seen this, I know it exists but you’re the first I’ve encountered using it.
  2. On the top right of your screenshot there’s an Auto button – press it see we can see the waterfall better and know what you’re trying to demodulate.
  3. Try offset tuning – don’t have the signal you want to demodulate in the center of the display, there may be a spur there (I think this is the case).
  4. In the Receive panel on the left:
    1. Close the audio display window – not needed (click the button next to the audio level a few times).
    2. Scroll down so we can see the Radio settings, I expect this is the problem, gains need adjusting.
  1. We’ll find the problem!

 

I’ve attached a screenshot of a Pluto rev B – you see the Radio panel on the left and Transmit spectrum on the right.

Good.  This must be a microphone setting, I’ve compared your log to mine and there’s no difference.

 

In the Device properties show me the window (below). I wonder whether there are some special options?

Um, er, it might right there staring him in his face, among all the odd settings. He's about 4 kHz off calibration; his audio is muted so of course he will hear nothing; he has gain set to maximum and video gain set to -30; he is set to full duplex (try simplex, make it work, then try duplex if needed); TX side has gains maxed out (overload can produce odd effects); RF bandwidth is a tad small for WX broadcasts; and I lost interest looking for more. (I have noticed that out of a fairly narrow band of Visual Gain settings the radio will blank. That suggests me Video Gain is not really only a gain for the spectrum related displays.

He should try 12 kHz bandwidth. It will sound better. (He should NEVER try to transmit on that frequency. Never Never Never. I hope he didn't try it.) NOAA broadcasts are a wide NFM rather than the narrower deviation hams and many other services use. Channels are 25 kHz.

Is his antenna connected to RX or TX side? Is he set to use Pluto's AGC? (I don't trust it. Is there a strong signal out of his display range that is suppressing Pluto's gain?)

Is he set to NFM?

Simon, you might do some good to place current mode and IF bandwidth down in the status bar.

Well I decided to update the Pluto firmware to 0.34 - now I am not receiving anything in SDR Console on the Pluto - for comparison I connected a RTLSDR and it's working fine.

 

BTW, the original issue was with TX audio from the Pluto being garbled - RX audio was always fine.  Also when I send the tone it was always fine on the other radio, I was monitoring both it on.

 

Advice on how to proceed?

Hi,

 

  1. PlutoPlus – first time I’ve seen this, I know it exists but you’re the first I’ve encountered using it.
  2. On the top right of your screenshot there’s an Auto button – press it see we can see the waterfall better and know what you’re trying to demodulate.
  3. Try offset tuning – don’t have the signal you want to demodulate in the center of the display, there may be a spur there (I think this is the case).
  4. In the Receive panel on the left:
    1. Close the audio display window – not needed (click the button next to the audio level a few times).
    2. Scroll down so we can see the Radio settings, I expect this is the problem, gains need adjusting.
  1. We’ll find the problem!

 

I’ve attached a screenshot of a Pluto rev B – you see the Radio panel on the left and Transmit spectrum on the right.

Um, er, it might right there staring him in his face, among all the odd settings. He's about 4 kHz off calibration; his audio is muted so of course he will hear nothing; he has gain set to maximum and video gain set to -30; he is set to full duplex (try simplex, make it work, then try duplex if needed); TX side has gains maxed out (overload can produce odd effects); RF bandwidth is a tad small for WX broadcasts; and I lost interest looking for more. (I have noticed that out of a fairly narrow band of Visual Gain settings the radio will blank. That suggests me Video Gain is not really only a gain for the spectrum related displays.

He should try 12 kHz bandwidth. It will sound better. (He should NEVER try to transmit on that frequency. Never Never Never. I hope he didn't try it.) NOAA broadcasts are a wide NFM rather than the narrower deviation hams and many other services use. Channels are 25 kHz.

Is his antenna connected to RX or TX side? Is he set to use Pluto's AGC? (I don't trust it. Is there a strong signal out of his display range that is suppressing Pluto's gain?)

Is he set to NFM?

Simon, you might do some good to place current mode and IF bandwidth down in the status bar.

Well I decided to update the Pluto firmware to 0.34 - now I am not receiving anything in SDR Console on the Pluto - for comparison I connected a RTLSDR and it's working fine.

 

BTW, the original issue was with TX audio from the Pluto being garbled - RX audio was always fine.  Also when I send the tone it was always fine on the other radio, I was monitoring both it on.

 

Advice on how to proceed?

Hi,

 

  1. PlutoPlus – first time I’ve seen this, I know it exists but you’re the first I’ve encountered using it.
  2. On the top right of your screenshot there’s an Auto button – press it see we can see the waterfall better and know what you’re trying to demodulate.
  3. Try offset tuning – don’t have the signal you want to demodulate in the center of the display, there may be a spur there (I think this is the case).
  4. In the Receive panel on the left:
    1. Close the audio display window – not needed (click the button next to the audio level a few times).
    2. Scroll down so we can see the Radio settings, I expect this is the problem, gains need adjusting.
  1. We’ll find the problem!

 

I’ve attached a screenshot of a Pluto rev B – you see the Radio panel on the left and Transmit spectrum on the right.

(I have noticed that out of a fairly narrow band of Visual Gain settings the radio will blank. That suggests me Video Gain is not really only a gain for the spectrum related displays.

He should try 12 kHz bandwidth. It will sound better. (He should NEVER try to transmit on that frequency. Never Never Never. I hope he didn't try it.) NOAA broadcasts are a wide NFM rather than the narrower deviation hams and many other services use. Channels are 25 kHz.

Is his antenna connected to RX or TX side? Is he set to use Pluto's AGC? (I don't trust it. Is there a strong signal out of his display range that is suppressing Pluto's gain?)

Is he set to NFM?

Simon, you might do some good to place current mode and IF bandwidth down in the status bar.

Well I decided to update the Pluto firmware to 0.34 - now I am not receiving anything in SDR Console on the Pluto - for comparison I connected a RTLSDR and it's working fine.

 

BTW, the original issue was with TX audio from the Pluto being garbled - RX audio was always fine.  Also when I send the tone it was always fine on the other radio, I was monitoring both it on.

 

Advice on how to proceed?

Hi,

 

  1. PlutoPlus – first time I’ve seen this, I know it exists but you’re the first I’ve encountered using it.
  2. On the top right of your screenshot there’s an Auto button – press it see we can see the waterfall better and know what you’re trying to demodulate.
  3. Try offset tuning – don’t have the signal you want to demodulate in the center of the display, there may be a spur there (I think this is the case).
  4. In the Receive panel on the left:
    1. Close the audio display window – not needed (click the button next to the audio level a few times).
    2. Scroll down so we can see the Radio settings, I expect this is the problem, gains need adjusting.
  1. We’ll find the problem!

 

I’ve attached a screenshot of a Pluto rev B – you see the Radio panel on the left and Transmit spectrum on the right.

Thanks.

 

I’m in the middle of something else for the rest of today, but let’s try turning up the gains:

 

  1. Increase Gain to 100 (it’s at 56 in your screenshot)
  2. Click the […] button on the right of Tune, look at gains, here are my settings, note the Boost:

I verified the mute button on the headset by listening to my own audio in the Windows sound device. 

 

The MIC has been unmuted the whole time.

I have a Logitech microphone I bought while in Finland, was in my office there, had a spare day and wanted to talk with Peter PH1PH (SK) about Ham Radio Deluxe. Must have been circa 2005.

 

Anyway, it has a mute button.

 

Also the input level in the Sound Control panel could be set to 0.

 

Or something.

Multiple sound cards or inputs and the microphone setting is to the wrong one? I have a USB card with both mic and line inputs. Which one works seems to be an item of chance.

Um, er, it might right there staring him in his face, among all the odd settings. He's about 4 kHz off calibration; his audio is muted so of course he will hear nothing; he has gain set to maximum and video gain set to -30; he is set to full duplex (try simplex, make it work, then try duplex if needed); TX side has gains maxed out (overload can produce odd effects); RF bandwidth is a tad small for WX broadcasts; and I lost interest looking for more. (I have noticed that out of a fairly narrow band of Visual Gain settings the radio will blank. That suggests me Video Gain is not really only a gain for the spectrum related displays.

He should try 12 kHz bandwidth. It will sound better. (He should NEVER try to transmit on that frequency. Never Never Never. I hope he didn't try it.) NOAA broadcasts are a wide NFM rather than the narrower deviation hams and many other services use. Channels are 25 kHz.

Is his antenna connected to RX or TX side? Is he set to use Pluto's AGC? (I don't trust it. Is there a strong signal out of his display range that is suppressing Pluto's gain?)

Is he set to NFM?

Simon, you might do some good to place current mode and IF bandwidth down in the status bar.

Well I decided to update the Pluto firmware to 0.34 - now I am not receiving anything in SDR Console on the Pluto - for comparison I connected a RTLSDR and it's working fine.

 

BTW, the original issue was with TX audio from the Pluto being garbled - RX audio was always fine.  Also when I send the tone it was always fine on the other radio, I was monitoring both it on.

 

Advice on how to proceed?

Hi,

 

  1. PlutoPlus – first time I’ve seen this, I know it exists but you’re the first I’ve encountered using it.
  2. On the top right of your screenshot there’s an Auto button – press it see we can see the waterfall better and know what you’re trying to demodulate.
  3. Try offset tuning – don’t have the signal you want to demodulate in the center of the display, there may be a spur there (I think this is the case).
  4. In the Receive panel on the left:
    1. Close the audio display window – not needed (click the button next to the audio level a few times).
    2. Scroll down so we can see the Radio settings, I expect this is the problem, gains need adjusting.
  1. We’ll find the problem!

 

I’ve attached a screenshot of a Pluto rev B – you see the Radio panel on the left and Transmit spectrum on the right.

Especially taken when it is acting up. There’s an important bar graph meter in the lower ribbon bar that will probably leave us to some conclusion.

Made the changes - still no audio - only clicking.

Thanks for looking at this - no rush - I know it will work.

Um, er, it might right there staring him in his face, among all the odd settings. He's about 4 kHz off calibration; his audio is muted so of course he will hear nothing; he has gain set to maximum and video gain set to -30; he is set to full duplex (try simplex, make it work, then try duplex if needed); TX side has gains maxed out (overload can produce odd effects); RF bandwidth is a tad small for WX broadcasts; and I lost interest looking for more. (I have noticed that out of a fairly narrow band of Visual Gain settings the radio will blank. That suggests me Video Gain is not really only a gain for the spectrum related displays.

He should try 12 kHz bandwidth. It will sound better. (He should NEVER try to transmit on that frequency. Never Never Never. I hope he didn't try it.) NOAA broadcasts are a wide NFM rather than the narrower deviation hams and many other services use. Channels are 25 kHz.

Is his antenna connected to RX or TX side? Is he set to use Pluto's AGC? (I don't trust it. Is there a strong signal out of his display range that is suppressing Pluto's gain?)

Is he set to NFM?

Simon, you might do some good to place current mode and IF bandwidth down in the status bar.

Well I decided to update the Pluto firmware to 0.34 - now I am not receiving anything in SDR Console on the Pluto - for comparison I connected a RTLSDR and it's working fine.

 

BTW, the original issue was with TX audio from the Pluto being garbled - RX audio was always fine.  Also when I send the tone it was always fine on the other radio, I was monitoring both it on.

 

Advice on how to proceed?

Hi,

 

  1. PlutoPlus – first time I’ve seen this, I know it exists but you’re the first I’ve encountered using it.
  2. On the top right of your screenshot there’s an Auto button – press it see we can see the waterfall better and know what you’re trying to demodulate.
  3. Try offset tuning – don’t have the signal you want to demodulate in the center of the display, there may be a spur there (I think this is the case).
  4. In the Receive panel on the left:
    1. Close the audio display window – not needed (click the button next to the audio level a few times).
    2. Scroll down so we can see the Radio settings, I expect this is the problem, gains need adjusting.
  1. We’ll find the problem!

 

I’ve attached a screenshot of a Pluto rev B – you see the Radio panel on the left and Transmit spectrum on the right.

OK - I fixed the receive issue after the firmware upgrade - I checked a UHF 432 and a UHF 1296 beacon that I had received before and they were coming in fine.  

 

I then checked the Pluto Plus chipset - it had reverted to the default AD9363 (Default ADAM-PLUTO) which only has a tuning range of 325-3800MHz - I used the command line commands via SSH to change this to a ADM9364 which has a tuning range of 70-6000MHz.

 

Now back to the initial TX garbled audio testing which has turned into no audio from a MIC now even with the latest firmware v0.34. 

 

Not getting any TX audio except on TX with "Tone" - see attached screen shot using MIC 🙂

I have a Logitech microphone I bought while in Finland, was in my office there, had a spare day and wanted to talk with Peter PH1PH (SK) about Ham Radio Deluxe. Must have been circa 2005.

 

Anyway, it has a mute button.

 

Also the input level in the Sound Control panel could be set to 0.

 

Or something.
