Update from a couple weeks ago:

Echoing Ed but for different reasons, I've now also joined the 21st century, and gone digital/visual readout/SDR. Well, kinda, so far. On Gedas' strong recommendation (many thanks, again), I picked up the RSPdx-R2 and have been playing with it for the last couple days. The good news: I've got signals! The not-so-good news: the SDRconnect software provided by SDRplay (which supports Macs which I use) has a steep learning curve, at least if you start from zero as I did. My first evening I was really excited to connect it up and did so, but got nothing no matter what I did, and finally shut down disappointed after a half hour of dead air. Then, the next day I discovered the drop down menu for antenna selection, switched to the correct antenna input of the 3 possibles, and bingo, signals magically appeared. That kind of stuff, baby steps, but they're happening and I'm gradually learning my way around. The SDRplay YouTubes are useful, but only to a point.

Which brings me to a question about QRSS: what software do the LOWFER cognoscenti on this board use for QRSS? Somehow I'm thinking it's not the SDRplay-provided SDRconnect software, since (1) I see no way to slow down the time-moving waterfall plot, and (2) I see no way to turn the waterfall plot 90 degrees to horizontal. So, I'm assuming I need something else.

Again, thanks to Gedas for recommending the RSPdx-R2. Any advice or pointers from anyone will be gratefully received by this digital/visual readout/SDR newbie. My goal is to hear/see my first ever LOWFER signal this winter while propagation is still favorable. I mean, TAG is only 110 miles away, and Gedas way out in IN is seeing it all the time. Surely, success must be mine, right?

73, Bruce WA1HGJ
