base12 has the advantage of being divisible by 2, 3, 4 and 6, while base10 is only divisible by 2 and 5.

Fun fact about that: in morse code, SOS is a prosign. This means it gets its own special rules.

Rather than being three seperate letters (… — …), it’s one letter without any letter spaces (…—…). This is something that applies to all prosigns in morse code, though most of them are just two letters long.

Also, when sending it on repeat you just continue the pattern without any spaces. Instead of …—… …—… (with a letter space) or …—…/…—… (with a word space), you send …—…—…—…—… and just keep continuing the pattern. iirc SOS is the only prosign where this is a thing.

Other prosigns are for example HH (…) to indicate a correction to something previously sent, and SK (…-.-) (silent key) to signal that you have finished with the current conversation and the frequency is now clear.

If you decide to set up an SDR for ADS-B, you might want to consider setting up a WebSDR with something like OpenWebRX. This would let people listen to all the signals in the bandwidth that you set.

If you’re interested, receiverbook.de is a list of most WebSDRs.

That looks really cool.

Have you tried using an automatic CAPTCHA solver (e.g. Buster)?

While, as you said, both wires will conduct electricity just fine, they will have different AC impedance.

I would guess this wouldn't make much of a difference if you go Audio->Ethernet->Audio, since sound is at fairly low frequencies. But Ethernet->Audio->Ethernet might have problems with really high data rates, like GiB/s.

I don’t know, I didn’t make this.

Thanks, I didn’t know where it came from.

Ahh, sorry my mistake. I remembered reading a headline somewhere about Google having already implemented it, but I didn’t check. Thanks!

It has allready been implemented in Chromium/Chrome (link). Websites only have to start using it.

Edit: see comment

This mostly wasn’t actually Google, the website it refrences was written by ChatGPT, Google’s crawler just found it and shows it in the summary.
