Chasing waterfalls

In a previous post, I mentioned setting up the SuperAntenna indoors. However, I couldn’t get it tune much of anything. I ended up building a dipole with the legs roughly 8¼ feet long (e.g. for the 10m band), however I couldn’t get it set up fell length indoors, so it ended up with the legs at 90° angles to each other.

This antenna uses an antenna hardware kit I’ve had lying around forever, along with some silicone-coated copper wire I have a couple small 100′ spools of. I figured better to construct the antenna and see what happens. Well, here’s what happens:

This is the antenna tuned up on the 10m band. I need to spend some time thinking about what that SWR graph says about the antenna’s performance, but the point is that the antenna wasn’t bad. I still had a hard time picking anything up, but I tried this in the evening when the 10m band wasn’t so hot. I figured I’d see what else I could see. I’ve mostly stuck to the 40m, 20m, and 10m bands, but there’s a couple more bands in between the 10 and 20m bands (e.g. the 12, 15, and 17m bands).

Turns out I had the best luck on the 15m band.

I was able to receive a couple signals decently enough, including one that I think is a PSK31 signal.

Here’s a short video of the signal:
