I've been occasionally fooling around with software-defined radios (SDR).
Considering the theme I thought I'd provide a few useful links for anyone willing to try out perhaps for inspiration or general interest. :signal_strength: :radio:

If you comes across some catchy oriental tunes or clandestine governmental intel, act accordingly!
Here's another fun tidbit.
It just happens that yesterday you could read from the news that my country's air-force conscripts were expressing themselves in quite a creative way.

I don't know whether to construe this as as a signal of distress or delight! These works of art could be observed in Flightradar24.
It's quite amazing that nowadays even ordinary folk can observe almost all aircraft going about. The other day I was looking into the standardized tech which makes it possible. Fascinating stuff!
When looking into the underlying definitions of SIGNALS, I bumped into this schematic in Wikipedia's article about signal processing.

I can't quite articulate why I'm inspired by it. But I might try to cook up something surreal but slightly going along these lines... Another angle I like would be to focus on biological or "organic" signals found all over the natural world.
Since I'm quite low on energy there's a real chance that I might have to settle with only devising ideas and concepts. But I'll try to come up with something really simple for the COMPO.
I was reminded of this doodle I made four years ago and managed to dig it up.

Might be I'll use it as a starting point, or might be that I won't!
But yeah. I'll end my collection of thoughts with an appropriate album I haven't listened to in a long time!

Prepare your transmitters for full operation!
