A lower frequency SDR?

[Bee Seventeen Bawmer]

Hello,

I am looking to receive lower frequency ranges in the area of 10 kHz plus or minus one or two, up to 15 MHz. (10kHz-15MHz

Is there any dongle out there now that can process this range?


I am very curious about these awesome little SDR dongles!

use upconverter

Yes, upconverter would be the only (relatively cheap) choice here. But I doubt you'll be able to receive as low as 10 kHz, most upconverters work from few MHz and up. I believe the reason for this is that dongles AGC acts like crazy around LO frequency and you see only spurs. Theoretically it can be solved with a good bandstop filter but even then I doubt that 10 kHz is achievable.

I have looked into the FunCube Dongle plus and they guarantee down to 150 kHz...

I am more focused on receiving the lower frequencies in the 10kHz-150kHz range, does anyone have any ideas on how to do this?

Is there a "lowconverter"?

[soooooil]

Well, yes, it's called upconverter
It does exactly what you want — shifts the lower frequency in the range where your sdr can receive.
The lower limit is slightly higher than DC only because of not ideal components. And there is not much you can do about it.

You don't need an SDR, just use your soundcard, a basic modern soundcard should get you from 0hz to 96khz just do some googling

a dxer I know is using Yosoo in direct sampling mode for these frequencies
