@baillehache_pascal while I know this is mostly chance and this pattern simply "looks like it", there are some features that are intriguing (like the horn-like features at both sides, also in the vicinity of the set). I wonder if there is some biological process that approximates (in a very broooad sense) the number of iterations of the Mandelbrot sequence, or something like that.
I left SigDigger running for the last 24 hours in HF @ 32 Msps. You can easily tell when the D layer of the ionosphere vanishes, enabling communications below 10 MHz. Useful? Not much, but damn isn't it beautiful?
Did you know that the Catalan word for chicken sounds like "chicken disaster" to Spanish speakers?
Also, I love how the following concepts sound in Portuguese to Spanish speakers:
- Pet ("esteem bug")
- Car Jack ("monkey")
- Ham ("allegedly")
I've finally tested my 3rd iteration of the varactor-based parametric amplifier. Gain is +20 dB. Test signal was Kate Ryan - Desenchantée (FM).

@baillehache_pascal yeah, I know it's a long shot. However, we tend to look to the set as just a bounded condition of an arbitrary sequence. But this sequence, once you paint it on top of the complex plane behaves as a very geometrical thing (like a spiral growing inwards or outwards). I can imagine some kind of cyclic biological process that either exhausts or explodes depending on where in the leaf it occurs.

Bom día. Sou espanhol e estou a aprender português europeu. Como é que é tão difícil encontrar conteúdos de Portugal na Internet? (estou a escrever este post porque @nirro@cascarilla.social quer máis actividade neste servidor).
More about my parametric amplifier, being powered on and off. The input signal is FM modulated, and the audio recording starts with the amplifier off. Then, I power it on right before the "tout est chaoooos" part, and then I toggle the power a couple of times more.
@g7vkq@mastodon.radio @scott@mastodon.clitheroe.ca 130 Msps is brutal. Do you happen to have any spectrum at hand? I am curious about its performance in LW / MW
@g7vkq@mastodon.radio @scott@mastodon.clitheroe.ca yes, it is a USRP B200, running at 32 Msp/s. I am using NooElec's Ham It Up, which shifts HF to 125 MHz (see "LNB" in the top - left, it is set to -125.000.000). Regarding the RX888 I have no idea, never heard of it until now. The specs are a bit odd, though: it says the VGA only applies to HF and VHF?
