SDR software on macOS survey

This morning I thought I'd listen to the ARNSW Sunday broadcast on a Mac using an RTL-SDR dongle, just for a change.

First I tried my old favourite, CubicSDR.

I like CubicSDR largely because of the nice keyboard commands for tuning around and zooming.

Next I ran GQRX 2.5, which works well. I noticed I could also receive the broadcast on 1273.5MHz.

Finally I stumbled across waveSDR in source code format by Justin England or getoffmyhack.

This is a wonderful piece of source code in modern Swift, very clearly written. Thanks Justin! It seems to have a memory leak and there's a runtime warning about reading a view's bounds off the main thread.

I had a bit of trouble figuring how how to tune it, the secret is to choose Tuner from the popup in the left panel. You can also click on the spectrum but dragging doesn't seem to work.
