I remember when the spam producing software tools came into wider circulation and some users just didn't fill out all the fields correctly, so the spam emails sometimes had <blank> and default entries.

If you'd ask me - what is the coolest piece of western #classicalmusic (in the broad sense), I might just bypass my adored all time favorite J.S. Bach and point to this, by Claudio Monteverdi

overseas or further from sweden, you may need a better antenna. For me, a 10 meter wire hung across the yard hooked up to the input, and a ground connection for the ground was sufficient.
And here's the info& livestream:

Since the transmit frequency is in the audible spectrum, it can be picked up directly using a sound card without any reception hardware. The only thing that's needed is a software that converts the 17.2 kHz pulses to the easily audible range and does some filtering:

On Tuesday, you can listen to the last remaining fully electromechanical #radio transmitter just using a computer microphone jack and a long wire (if you're in Europe).

It will start up to commemorate UN day, and will send a message using morse code.

The frequency is an absurdly low 17.2 kHz/

Hello everyone! I'm enthusiastic about fundamental physics, a field I have worked in years ago, energy and in particular prospects for nuclear technology as a climate technology, teaching science, and lately, I spend a lot of time thinking about electronics and amateur radio

Cheers!
