Re: Audio Selection

Conrad, PA5Y
 

That is the best-case scenario for virtual soundcards, but it is dependent on the routing, whether you are using MME, WDM/KS or ASIO . But virtual soundcards have a buffer, to help with under runs or over runs and therefore data may not arrive when expected. To some extent there will be some sample shifting due to timing errors. This means that degradation can occur.

 

But VMP handles all of this very well and certainly produces the best results.

 

If you read this:

 

https://documentation.help/Virtual-Audio-Cable/advanced.htm

 

It is all explained, but you must read the whole thing as well as some hyperlinked pages to get a picture.  I wish that I could find a better reference, there is a lot that I don’t understand, and it really affects my EME operating. If your signals are well above the noise floor then this issues are a lot less important, or at least that is what I observe.

What if the soundcard is just a virtual card.....and you have a handfull of them all calculated from your main cpu clock...?!?

You can monitor any signal via the main output device. Like a real mixer it as solo buttons.

so now have 4x vac besides the 3 that potatoe brings with .. means 7 virtual cables used here together with the full blown mixer

(and additionalli installed lighthost and a few vst plugins to give my audio a better punch and sound)

Re: Audio Selection

Conrad, PA5Y
 

That is not true of virtual sound cards. There is ALWAYS some sample rate conversion. To save you reading all the documentation there are two very important things to consider.

 

1.‘When a Virtual Cable is used in a path containing another audio device (a hardware device, a software device other than Virtual Cable and even another Virtual Cable device), clock difference effect occurs. To minimize it, change cable clock correction multiplier until cable internal clock speed becomes closest to another device clock.’

 

2. ‘VAC uses relatively simple linear resampling algorithm and does not use dithering or other advanced smoothing features. Therefore, conversion results may sound worse than an original signal. To prevent quality degradation, you need to pay attention to a format matching. In an ideal case, all three formats (the playback client's format, the cable format and the recording client's format) are the same.’

 

You can read the whole article here:

 

https://documentation.help/Virtual-Audio-Cable/advanced.htm

 

Voice Meter uses more sophisticated methods and does it better.

It has a similar effect to poor phase noise on weak signals with up to 2dB degradation when compared to a radio (K3S or TS-890) and a soundcard. This does not happen with VMP. I don’t know this for sure, but I think if you use soundcard with a decent clock such as a UMC202HD as the master output device this becomes the reference clock. I could be wrong as this is not made clear. However, I am sure that VMP is much better than any other virtual soundcard solution that I could find 18 months ago.

You can monitor any signal via the main output device. Like a real mixer it as solo buttons.

i use potatoe from the same company ... works superb

also downloaded vac plus vac_a and vac_b and hificable

so now have 4x vac besides the 3 that potatoe brings with .. means 7 virtual cables used here together with the full blown mixer

(and additionalli installed lighthost and a few vst plugins to give my audio a better punch and sound)

so .. i can highly recommend the mixer and the virtual cables

Zoom lock and Panadapter back to "normal" op

Robin Thompson
 

Hi all

Just wanted to confirm on SDRC that there isn’t a way of locking the Zoom facility on the waterfall display, without locking the whole programme ? Using it on CW with an IF panadapter on 124Mhz with my IC7100 … really good to able to Zoom into that part of the band,  but Zoom reverts to default on a change of frequency.

 

Also, what is the quickest way of reverting to “normal” SDR operation out of the above IF shift mode ?

Would the best option be to create a different “Identity” and restart the programme ?

Re: Cordless phone RFI

Alan Higbie
 

Interesting coincidence that you are discussing how you used SDR-Console / SDRPlay to track RFI from DECT cordless phones.

For the first time - I did just that this week while helping a friend.

We are tracking 2 RFI sources:
(1) powerline source causing RFI on HF has been located &
(2) some (as yet) unknown source causing interference to his AT&T and Panasonic DECT phones.

These DECT phones operate in the 1.9 GHz range.  The exact frequencies were in the user manuals. 

In investigating this phone RFI problem, we used SDR-Console with an SDRPlay RSPDx.  It was very interesting to visualize the transmissions from the base unit and the handsets.
His phone RFI is interference TO HIS PHONE - - vs. Allan's RFI from a DECT phone.

I have tried other SDR software - but for RFI sleuthing, SDR-C is the best.  Its Signal History feature is most helpful. 

For anyone interested in locating and mitigating RFI sources, be sure to search archives of the RFI reflector:
http://lists.contesting.com/mailman/listinfo/rfi

Also, the ARRL's website has a very good RFI page:
http://www.arrl.org/radio-frequency-interference-rfi

Earlier this year, WD8DSB developed a small UNIDIRECTIONAL and BROADBANDED portable loop antenna for RFI hunting. It was the cover story in QST March, 2021.
To me, it seems like a breakthrough.
It pairs very well with SDR-Console, SDR receiver, and a laptop.

Re: SDR server synchronize with collocated Kenwood radio?

Gordon LaPoint
 

We are using RCForb server at the remote and RCForb client on the local, sometimes with DXLabs for logging and radio control.
I will experiment with using the local SDRconsole that is connected to the remote and see if I can get the local interface going with the Hamlib software interface.

I run a remote setup with a Kenwood TS-590sg and an RSP1a. Can the V3 server be run and synchronized with the Kenwood?

I can synchronize the V3 client with the kenwood, but want to access the server over the internet while using the Kenwood via RCForb.

Right now to see the SDR display I have to open a remote desktop to the server computer, I would like to eliminate that step.

Thanks Dale !

You know all this technology that we currently have available to us is just mind blowing. I mean here I am in my recliner listening to VLF down around 20 kHz and just 5 minutes ago had an S9 RS QSO up on 10 GHz. Never could I have imagined having all this fun when I was a kid (punk). If only kids nowadays knew how lucky they are to have all this at their fingertips !
