Hi All,

This is a continuing saga of my getting a Softrock LF operating properly (again).? It has been a number of years since I last used one, and the one Tony sent me seems to work quite well (with a few quirks).? But one thing I could NOT do was get a 192KCs bandwidth in the NDB band where I listen.? About 96k was the best I could get.

I had bought a new Creative Soundcard to install in my Tower computer as the soundcard it had seemed a bit "hissy".? This is the soundcard I bought, as it said it was 192k.

After I finally got into the Win 11 setup for the card , try as I might, I couldn't do any better than 96k, and that is all that HDSDR would let me do.

Finally, in desperation, I plugged the Softrock into the soundcard that came with the 'puter, a Realtek that is apparently part of the motherboard. ? Well, imagine my surprise when I went into HDSDR and it let me set the card up for 192K, and I can see that bandwidth in the display.? Seems to work quite well, except that I do get a "clip" indicator.? I've NOT figured out a way to lower the gain of the card that works, (Win11 is TERRIBLE about letting you change things).? But at least it IS working, but I noticed that I seem to have three very strong bands of IMD or "noise" (not listened to it yet) in the waterfall.? Something that isn't "real" as I don't hear them on the Yaesu receivers using the same antenna/ multicoupler, etc.

But otherwise the receiver seems to work well, in three nights recording (while it was still only 96k) I logged quite a few NDB's, including several Alaskan ones that I always welcome here. . .

This is interesting! I haven't used my Softrock RX Ensemble II since Linux
Mint (apparently) dropped the driver for my M-Audio 192k card.

The motherboard on that Dell died (the bad electrolytic capacitor fiasco)
and now I'm using an Asus VivoPC VM60 mini computer with Debian 12 KDE
Plasma. (Dual boots into Manjaro.)

Any 192k (or higher) solutions for that? USB maybe?

to set the gain you can open a terminal and run alsamixer , select the card
, and then toggle to the input or AtoD gain .
