A problem with Virtual Audio Cables

Paul Gulliver
 

I'm using SDR console V3 to receive C-Band aero signals from the Inmarsat satellite - my setup is: RSP1A into SDR console, console has 9 receivers feeding 9 instances of Jaero decoding software each fed via a virtual audio cable.
Everything works fine for several hours then for no apparent reason the link is lost on all VAC's between console and Jaero - the signal is showing on the waterfall in console but not being passed on. The VAC links can be re-established by closing down console and re-opening it..
Has anyone experienced this sort of problem or any ideas where to look - the trouble is this receiver setup is supposed to run 24/7  so the problem is a bit frustrating.
All being run on a Windows 7 laptop

Hi all

I did most likely overlook something in my settings. New nstallation of SDR console 3.3 after a long break with my local SDRs (Afedri, Airspy and Funcube) worked fine. Everything seem to work with one exeption: When I tune in to a signal, i.e. a cw beacon, I hear the signal until I stopp moving the VFO, then the ton disappears like a nocht filter was active and a just hear the white noise despite the signel is clearly visable in the passband of the waterfalll. Thr notck filter is switched off! Any hints?

TNX!

I see this issue has now crossed several messages and seems fairly widespread.
That being said, there seem to be many not affected so that adds to some frustration.

I would have hoped the log files might contain some clues, but apparently not.

I could replace my entire network but have no assurance this is
truly a "network only" issue. I think my best course of action is to bring in a new 
PC and configure the server and see if that end has any effect. Having three clients all
behaving near the same, at least I may be able to isolate / eliminate one variable at
a time. And it's less timely and expensive that replacing an Asus high end router and reconfiguring our
entire network, again with no positive that these hours / $$ would resolve the issue.

In case it might get looked at again, attached is the latest screen shot. 
It would be bitter sweet to have to run up a white flag.
But...….

Isn't it still true that coherent reception on the 2 radios is not possible out-of-the-box? That would be a terrible shame.

I'm beginning to wonder if this is Spectre/Meltdown mitigation hitting streaming performance.
If so would differ between CPU's and BIOS's.
If you can, update your BIOS on any Server and Clients where stutter is seen, see if it affect anything.

BTW Kriss sort of got your lustration but had to hold my head sideways for the post-email-group formatting.
Good luck with the barn door, hope the horse is still there.

That's an old Net Gear 10/100. There was not much traffic through it, just occasional ADSB traffic, and the SDR-iq#1/SDRPlay #1 server was not in use at the time.

The DD-WRT modified router is there to give me an WAP out in barn (shop), so the wifi part really isn't in use now that I ran Cat6 over to repeater shed. I just use the ports as a switch for now.

Will spend more time later today, barn door folks are due to arrive any minute...

Kriss:
Logfile attached. No stuttering detected this AM. Currently listening to 75 meters and
clean.

I am having the stuttering issues on my LAN / Server. The log looks very similar to you and I am struggling
to figure it out and the significance of our constant restarts:

Radio V3Server> Flow control: sleep 5 ms (restart timing)

All my clients affected: laptops, WIFI, ethernet, desktops.

Quickish reply,
The "DD-WRT Router(Repeater Bridge)" is a red flag, WiFi repeaters can half the available bandwidth as they receive and retransmit the data, WPA bridges can be a bit slow anyway, add in clients and it's not a good arrangement for throughput.
That with 100M switches stands out to me as a bottleneck. If you don't actually use the repeater side just dedicate that WiFi to P-P and use another access point for clients.

I've gone over to fibre here as Mikrotik stuff is excellent value and two Managed 5 port Gig switches with fibre SFP (1.25G) modules and 30m of OM4 fibre should be less than $200. Would need a bit of trunking for that "inside" fibre but outside fibre is not that much more

If you must go WiFi then look at some dedicated 5G point to point from Ubiquiti (or even TP-Link).

5 port Gig switches are cheap now, IMO time for a refresh.

Cheers

Stu

BTW Libre office draw is free and excellent for quick sketches others can easily visualise..

Doesn't matter what bandwidth started or switched to.
The SDRPlay #2 on a neighboring netbook in the repeater shed operating at 1MHz bandwidth runs just fine from the client machine through all the network pieces

Can folks outside my LAN access my SDR-iq #2 and #3 and see how it behaves?

Re: LimeSDR - Transmit Status

steve@...
 

Hi,

I just wanted to check if we should currently expect a PTT ouput on the J12 GPIO yet ?

The other option that might work (for me anyway) is if there is a way a run a custom script at the start and end of a TX.   I could then send commands to my switching board to control TX/RX switching.

thx,
Steve

You most likely need something but you need to tell us what SDR you have.

Understand. SDRsharp has a plugin that allows it to send data to RSS. It was written by Alan Duffy. In fact just last night I finally got it to work sort of but it is buggy and crashes a lot. It is just a small dll file. So may not be too difficult. Understand about your schedule we all appreciate your expertise and work. Thanks!

OK – I didn’t realise it was FFT output needed. I’ll not have time for this project until Q3 2019 at the very earliest.

Here is what I received fro Jim Sky.

Hi Larry,

No file was attached, however, RSS doesn't read IQ files.  What we need is a live stream of the reduced FFT data from SDRconsole as per the blog instructions. Both programs would have to be running at the same time with SDRConsole feeding the live data to RSS.

Ron,

 

I’m watching this new Red Pitaya – if it’s as good as is claimed then I may be tempted, but in general I’m moving away from HF.

Simon, one of my friends owns a RedPitaya and is very pleased with it. Obviously it needs good bandpass filters to work fine. I can borrow it for a while if I want. It seems to need a specific software to run it as it seems.
