Hi Dick

This has been discussed before. Seems max bandwidth achievable in this setup with CWS is around 24 kHz regardless. I've also found this to be the case in practice (as you can see from my comments in linked posts below).

See these links:

am I trying to do something Console was not designed to do?
Dick,

No, something Skimmer was not designed to do.
It only does 192ksps with certain SDRs and only on it's own.

Fabio,
   Is the DSP panel visible? The DSP panel has frequency, audio output selection, volume, mode, filters, etc.
Click on the Receive tab (#1), the DSP (#2), then choose the output device and adjust volume (#3).

CW Skimmer Bandwidth

Dick Williams
 

My objective is to generate DX Cluster style spots for CW stations heard between 50.000 and 50.125 mHz. I'm trying to do this using Console to feed IQ data to CW Skimmer as described in https://www.sdr-radio.com/cw-skimmer with an RSP1A. That site suggests using a 48 kHz sample rate. My thought was that I could use the same setup but increase the sample rate in Console, VAC, and Skimmer to 96 or 192 kHz to get close to or exceed my objective.

 

I used a 48 kHz sample rate in my first attempts. The results there were promising until I looked at Skimmer's Bandscope window. It showed a bandwidth of just about 30 kHz. I had expected to see close to 48 kHz. I then set Console, VAC, and Skimmer for 192 kHz. Again, Skimmer's Bandscope window showed a bandwidth of just about 30 kHz. It looks to me like something is limiting the bandwidth of the I/Q data to about 30 kHz regardless of the bandwidth selected.

 

My question now is have I missed a setting or settings in Console that limit the IQ data bandwidth or am I trying to do something Console was not designed to do?

Many  thanks  for  your  reply  Max..

I've  downloaded and  installed  SDR Console  V3,  but  it's  not  OK. 

  I  used,  for  the  installation,  the  tool   Select  Identity  ( the  screen  was dark) and  ,after, i    did  not  select  the  window  MAIN,  but   ALTERNATE.  In  this  way  I've  seen  the  "waves"  of  the  stations, but  i  don't  hear  the  audio.

Where is  the  mistake?

Quite right Fabio, you came to the right place!

1) Go to https://www.sdrplay.com/downloads/ and install API (3.09 latest version works fine with SDRC). If you already installed the API as you will have done if SDR Uno is working, then no need to do anything further.

Then add the radio to SDRC (see attachment to this message):

(A) Run SDRC

(B) Top left of main screen, "Home" tab selected "Select Radio".

(C) In the panel that opens click "Definitions" and then "Search" and select SDRplay V3, then "Add".

(D) You should  now be able to "Start" the radio.

Regarding lists, yes, you can add HFCC:

https://www.sdr-radio.com/frequency-database

Although, for some fantastic functionality with SDRC, I urge you to look at CSV UserList Browser. They work brilliantly together:

https://www.df8ry.de/htmlen/csvub/%F0%9F%91%93features.htm

Video shows use with SDR Uno, but it works just as well with SDR Console:

RSPdx and SDR Console

ffiorin@...
 

Hallo  to  all  the  memnbers  of  this  group..

I  hope  that  someone  can  give  me  the  right  suggestions  for  my  problems..

I  own  a  RSP  receiver  (dx) which  I use  with  the  software     SDRPLAY (release  1.41).

The  software  is  fine  and  I  can  receive  many  stations (broadcasting    and  utility). In  my   opinion   the  software  is  not  very  easy, because    some  options  need  too many  steps  to  work. One  of  these  is  the  creation  of  the  broadcasting  lists.  After  many  attemps  I  installed  EIBI  list    using  CSV  browser  and  a  program  for  the  virtual  serial  ports  named  VSPE.  I  noticed  that  this  list is  not  exhaustive,  because  misses  some  stations.  I  have  tried  to  install  the  more  complete  HFCC  list, but  I  wasn't  able  to do  that..

So  I  have  decided  to  use  SDR  console   V.3,  which  seems  easier  to  use.  I  would   like  to  know the  following  things:

1) In  some  tutorials  I've  seen  that  i  must  install  first  the  API  drivers.  In  what   folder  have  I  to  set  these  up? 

2) Is  it  possible  to  install  in  SDR  console  the  HFCC  list?  What  program  have  I  to  use?

In  order  to  recognize  the  frequency lists,   I  use  the    program   ERGO  in  my   old  "analogic"  receiver  (JRC  NRD535D) .  I  have  been  told     to  connect  ERGO, using  SDR  Console,  to  an  external  serial  port.  Then  I have  I  to  use  VSPE  again  to  create  the  serial  port  and  make  the  same  steps  as  before?

   73  to  all the members ,waiting  for  an  help.

Fabio

I had the newest firmware loaded. Same irmware worked fine with another FDM-DUO.

Finally I got help from Elad. After a 30 minutes TeamViewer sessiom they rewrote the whole firmware again and fixed some corrupted offset data in the FDM-DOU internal emory. That was it! SDR-Radio Console is now working on RX and TX, at least in SSB an FM. I cold not transmit in CW and I could not establish a working server to console connection with the FDM DUO (with FunCube it is working) so far. But this is another issue.

Many thanks for the support here!

Its probably not a level problem, its all in the timing and, in a computer, if a signal takes two paths one path is slightly delayed with respect to the other. If they are then recombined, there is either phase cancellation or, in extreme cases, actually two distinct signals like an echo.

On a computer, your NOT really listening to what you think you are.
Remember that computer audio is fairly complex and is designed to merge multiple sources into what you hear. At a simple level, it puts both "program" audio (music, zoom, SDRC, etc) as well as system sounds (warnings,, notifications, alarms, etc) into your speakers/headphones.

So... what is FLdigi REALLY "hearing"?
It depends on how your routing the audio internally and what you told it to listen too.

Windows designed a truly horrible sound architecture. Its levels all interact and routing is both a complex, error prone mess and severely crippled in functionality at the same time.
When you add in virtual audio cables (which you often have to do because of the crippled windows audio routing), it can get confusing in a hurry and there's a tendency to go "great! I see level! and stop.
Something that may help is to draw out the signal path and try to keep it as simple as possible:
SDRC -> Virtual Audio Cable ->FLdigi->speakers
is much better than:
SDRC->Virtual Audio Cable->FLdigi>Speakers
         -> Speakers>Fldigi
                                             ->Speakers->Mic->FLdigi
Which may work, but not very well, and is all too easy to achieve.

Here's a place to look for issues:
Start the whole thing up, SDRC, FLDIGI, Virtual cables etc.
Document EVERYTHING that you touch before you touch it so you can get back if you need too! I find a cell phone camera rerally handy for this, but check the pictures to make sure they are clear.
Look at the settings for audio in/out on each app in the chain, do they make sense when drawn out?
Now look at  Windows Audio built in routing and settings...
In the search bar (usually bottom left of the display) type the word Sounds and hit Enter
Now, go through each item, lets start with Playback and Speakers
Select them and click Properties
Go through all the tabs. make very sure that all "enhancements" are turned OFF. The "Kiddy Kewl Super Pro Enhanced Bass Processor" isn't going to help with what we do.
On to "Recording"
Real Microphones should be OFF! we don't want audio from the computers mixing with our real feed! (if you need them form Zoom, or whatever, dont forhet to turn them back on. You can experiment with settings later to figure out how to make life easier and have the things work for Zoom and not play havoc with our digital decodes.
On the "recording" sources "properties" there's a confusing option called "Listen to this device". Be careful! this is where things can get nasty. All that box does is enable the recording source to go straight to the speakers. you should only be listening to ONE device at a a time! Just to confuse things, FLdigi also has the ability to monitor the audio and so, effectively, becomes another recording source as well as a target. Those settings are in FLdigi, Configure, Config Dialog, Soundcard, Devices.
