What receiver are you using? 24 MHz is the lower frequency limit of an RTL-SDR dongle unless you are using the direct sampling mode, so you may have encountered that.

Hi, I think you need an UP Converter (hardware, e.g. HAM IT UP from Nooelec)

First day.  GQRX 2.6 Never knew that the device needed any other hardware.

Hi, is it true that SDR. Com runs only under Windows and there is no Linux binary or source code for installation.?

I don't have any windows machine, SDR COM V3 runs perfectly with GQRX under any Linux version.

Hi Oliver, excuse me I know this is not the right place for my addtional question regarding SDR.COM Console. I did not found  a Linux installation source.  There is only a .exe file for Windows (32 or 64 bit). I gues you install SDR.COM software on Linux PC with VMWare Windows - is this that right?

Aah ! you were talking about SDR Console, I was thinking you were talking about the dongle SDR.COM V3 wich is not the same approach. I don't know if it's possible to run SDR console under Linux, maybe with mono, I don't know. I only use GQRX and Cubic SDR under Ubuntu.
Regards.

Oh, now I understand you. With SDR. COM dongle is it possible to receive below 24 MHz. I have an SDR_RTL dongel and in this case I need an UP Converter or tricky construction with direct sampling.
Best Regards Claus
