Hi,
The virtual signal mode was present in the early release of ExtIO_sddc.dll. It is no more present from version 1.x

Please use the latest release 1.20 https://github.com/ik1xpv/ExtIO_sddc/releases/latest
The required files are ExtIO_SDDC.dll libfftw3f-3.dll
They can be downloaded from the archive SDDC_EXTIO.zip at https://github.com/ik1xpv/ExtIO_sddc/releases/download/v1.2.0/SDDC_EXTIO.ZIP

Or even better the prerelease v1.3.0RC1 the archive is at https://github.com/ik1xpv/ExtIO_sddc/releases/download/v1.3.0RC1/extio-package.zip
The application HDSDR.exe v 2.0 or v2.81 can be downloaded from https://www.hdsdr.de/

Connect the BBRF103 or RX888 without running HDSDR. It must be seen in the connected USB devices as "Cypress FX3 Boot Loader Device" If not there is a problem with the Cypress driver or hardware (by the way is the port USB 3.0?)

Thanks a lot now running in HDSDR but no audio ? SDR sharp 1732 works but I can't adjust the gain - it's deaf atm. SDR console 3.0.24 what to do ? Latest version works ?

Update : ok SDR sharp works ok but how do I adjust the IF bandwidth down from 32MB ? Also I keep having to change settings each time I close down / start up again

The max IF bandwidth processed depends also by the application.

While HDSDR processes 32 MHz in real time or 64 MHz when the setting of adc clk is 128MHz,
some application are able to manage only slower rate and
some others can manage 32 MHz signal stream while the real time display of IF spectrogram is limited to a narrow band.

Settings are managed by host application with the EXTIO_API ExtIoGetSetting and ExtIoSetSetting
If the application do not uses them the setting are not saved,
See https://github.com/ik1xpv/ExtIO_sddc/blob/master/ExtIO_sddc/ExtIO_sddc.h

OK anyway all 3 progs working now. Most compatible is SDR console 3.1 followed by HDSDR, SDR sharp is all over the place certainly with VHF for weather sats but MW is good
