Re: Issue with "Ghost Audio" when using with RSP2 #rspduo

bigtalk1233@...
 

Yes, I can go to Windows mixer, and if I mute or turn down Console the audio goes away. So it is definitely being synthesized by Console and piped to the default audio device, irregardless of how the receivers are setup or if there any.

This only happens with the RSP2 and Console. If I switch to a different client program, the problem doesn't occur. If I switch to a different SDR, the problem doesn't occur. I tried it on a few machines, including laptops not connected to power or anything else, and it happens the same each time with this combination, so I don't think it is a ground loop or anything electrical. I'm also fairly certain this didn't happen prior to version .18 but I can't find my copy of .17.

Check your automute setting. The input levels got to high and it's triggering. Set it higher or turn it off.

When using SDRC with the Perseus or Elad S2, there is no signal (spectrum and waterfall below about 2 mhz.  Both radios work fine with their native software.

You can see what happens in the video as I tune below 2 megs.

Any thoughts for what is happening.  I have rebooted and tried what I think are the normal type solutions.

Re: RSP1DX

What are you using for an antenna? Through 30 MHz it takes a really terrible receiver to have more noise than the natural noise level picked up by moderately good antennas.

Hi George,
I have an Airspy S2 and an SDRPay RSPdx and they both play well with SDRC.

Performance wise there are clear differences and I find the RSPdx a bit deaf compared to the S2, especially on 6 meters.

When I compare the raw number of decodes on FT8 per 15 sec sequence, or the same decodes per seq using MSK144, the S2 is quite a bit more sensitive. I am driving the SDRs from my Kenwood TS-590sg antenna output port, which loses 3 dB of signal, but that has not proven to be a factor.

If you look at the specs of the RSPdx, it has a very high noise figure on HF especially. I found at my rural qth, a wideband preamp made a big difference. With the preamp, the performance of the RSPdx is equal to or better than my TS-590sg on all HF bands.
Again, the measure in number of decodes/sequence on FT8. I pay little or no attention to the raw SNRs, as they can be quite misleading due to AGC characteristics.

The preamp has caused no overload issues of any kind. I don't use the RSPdx for BC band reception as a rule, but I have no overload or intermod issues from either FM or BC stations to my work on ham radio bands, and very good antennas.

For normal HF work, the RSPdx is quite good, clearly better than the FunCube Pro+ on HF (the FC+ is excellent on satellite work with an appropriate GASfet preamp)

On 6 meters, even with the preamp, the RSPdx is not in the same league as the Airspy S2.

So, if your interests are HF, the RSPdx is fine. If VHF, not so much.

Re: RSP1DX

Give the whole frequency range you want to cover. 108 MHz to high energy X-Rays is a little much to ask for. AirSpy HF+ models go to 260 MHz. AirSpy R2 makes it to about 1750 MHz. Lime USB (not the mini, please) makes it to around 6 GHz. After that you are talknig about serious money.

So what would the experts out there recommend as a good SDR receiver for 108 and up (in frequency)?

Of course I want it to be "very" compatible with SDRC, of course.

Thank you for any suggestions.

Re: Issue with "Ghost Audio" when using with RSP2 #rspduo

OK, I think you just proved it is not SDRConsole providing that audio. You should be able to prove it by clicking on the audio mixer, finding SDRC in its list of controls and muting it.

With no receivers active SDRC is sending out all zeros, silence, if it sends out anything at all. So something else would have to be providing the sound you are hearing. If this only happens with the RSP2 that suggests it is related to the RSP2 demands on the USB power bus leaking into the audio system on the motherboard, This is not something Simon can fix if that is the case. Does the RSP2 have an option for separate power? If so try that.

Are you using a USB audio card? If so place it on a separate USB2 powered hub from the RSP2. Ideally move the RSP2 to its own powered hub. This MAY help. But this also could be pickup on your wiring from a very strong local station. But there is nothing in a basic SDR design that would provide a software path for this audio into your motherboard audio.

The audio produced sounds like it is highly filtered, about 100Hz of bandwidth around 2800Hz centered I would estimate, and with big +40 signals it becomes quite loud.

Here's my RSP1A on 2 meters, notice the signal strength of the repeater at 146.700 as 90 dB above the noise floor (the small mound at the floor of that signal is repeater splatter). The little RSP1A handles that dynamic range just fine.
No, it is not "repeater splatter" - it is LO phase noise. If you try the same test @ 70 cm you'll find that "splatter" consistently 10 dB higher relative to the carrier. This is a significant problem that is driving me away from the SDRPlay product & towards Airspy: the AirSpy Mini's phase noise is 10 dB lower.

Also wonder how you can get 90 dB of dynamic range when the RSP1a's ADC is 14 bits (84 dB max. possible)? Since you're sampling at least 3.6 MHz decimation isn't coming into play.

What is the resolution bandwidth of the spectrum display?

I would like to thank everyone who responded with ideas and suggestions.  This group's members are always so quick to jump in and help.  I really appreciate that.

It was indeed the auto mute setting.  Not sure how it got set, but obviously I hit it somewhere along the way.  There are so many features of SDRC, that learning what every thing does, I sometimes just don't know exactly what they do.

Again thanks to all.  enjoy your weekend.

You are right, George. This is odd. The only thing that springs to mind is the antenna.

Are you feeding both receivers from the same antenna? Is it maybe an active antenna that has a fault and cutting off below 2MHz?

Or do you have a filter or something in the feeder?

Perhaps try a wire or whip directly into the receivers?

Can’t think of much else.

Sounds more hardware than software but check filter settings in SDRC to be sure. I don’t have these radios, so this is conjecture on my part.

Good luck hunting this one down.

Re: USB timeout 10 minute W10 in Parallels

John W0MPM
 

Went into the windows device manager and Universal Serial Device Controllers of which found 3. Two "USB Root Hub", and a single "USB Root Hub (USB 3.0)". Looking at the properties found the 'Power Management' property of the "... (USB 3.0)" was set to "Allow the computer to turn this device off ..." and unchecked that permission box.

No change. After 10 minutes the Airspy HF+ 'turns off'. The amber power lite is still on but the blue lite that turns on when HF+ is running is off; and SDRc is not frozen. The corrective action is to 'Stop' the radio (takes 5 to 10 seconds) then 'Start' the radio again. 

Is there an equivalent MacOS setting to look at that would keep the USB device on or ...?

Not sure what to take a picture of. This is a screenshot of the task manager when everything is working normally. SDR Console varies between about 9% to 17% usage.

The problem is that you do not have the receiver tuned to 215Khz but the radio 1mhz bandwidth is centered such that the lower end is above 215Khz. There is a checkbox somewhere that automatically moves the radio bandwidth center if the tuned frequency is out of range. You could use that or you could drag the bandwidth bard (below the waterfall window) down to where it includes 215Khz.
