New PowerSDR software

I had experimented with PowerSDR/IFStage software last year with the K3, but the old version didn’t support a 64-bit computer, which I’m running. So I let it alone for a few months and checked the web site Sunday and there is a new version,, that supports the bigger computer, so I downloaded it. As with all software upgrades, it didn’t work right at first, but that’s half the fun of this stuff. I soon figured out I’d have up upgrade the LP Bridge software as well, and after I did that, it still didn’t work. Then came an hour of trying different combinations, and looking carefully at all the setup fields, and suddenly, I saw the problem. I checked the right box, and it works great. The PowerSDR, combined with the LP-Pan Panadapter, gives me a nice panadapter and computer. Here’s a short video of it in action.

CW decoder

I was having a very nice conversation (at 30+ words per minute on cw) with Bill, KA1RVM, this morning. We were talking about radios — my favoroite subject — and started talking about cw decoders. I told him I was surprised how well the decoder on the K3 worked, and picked up the camera and shot this quick video of the K3 decoding Bill’s last transmission.
