Recommended USB sound card

[Nate Bargmann]

Hi all.

Yes, I've been AWOL. Good to see Tor is keeping up SO2SDR.

Some years ago I bought a secondhand Softrock Lite II setup up for the
K3 IF with the intent of playing with the SO2SDR bandmap. Well, it went
into a drawer and...I pulled it out a couple of days ago and decided
this would make a small winter project, that of figuring out how to use
it.

I am looking for a USB sound adapter for this project. I've been
directed to the Asus Xonar U5/U7 devices. The U5 looks attractive but
it isn't shown on the ALSA Web site. I've been pointed to other devices
and all look quite high end, which makes sense when looking into the 192
kHz league of devices (with the plethora of SDR programs out there, I
would like to look beyond SO2SDR for this project).

I think a USB 2 device would be more future proof, so I am looking for
a USB device only.

73, Nate

Hi Nate,

I haven't kept up with what USB sound cards are available. For not a
lot more $ than a higher-end USB sound card you can now get a direct
sampling SDR. In the long run this is much more flexible. I currently
use an Afedri SDR-Net (https://www.afedri-sdr.com/). SDRPlay and
AirSpy are two others (I have not tried either of these). I like the
Afedri I have because it has an ethernet interface- in linux this
means no dealing with kernel modules, alsa devices, conflicts with
Pulseaudio, etc.

Thanks for those tips, Tor.

I may move in that direction, though I also have a FunCube dongle in the
drawer I've not done anything with for a long time either. As it is VHF
and up and I do have a spare VHF/UHF antenna I can took it to, maybe I
need to play with it too.

I opted to order the Asus Xonar U7 MkII from Amazon this morning since I
had reward points to spend. It will be hear Tuesday and I can find out
of this SoftRock even works!
