Listen to historic Grimeton station SAQ transmit tomorrow on 17,2 kHz (yes, you read that right, kHz)

It is in the audio spectrum and can be received via soundcard

SAQ scheduled to air on Alexanderson Day 2023 – The Alexander association

Get a load of this: SAQ is the only transmitter in the world that produces its RF straight from a generator without any electronics whatsoever! (alexanderson transmitter)

Like, just turn the wheel fast enough and hook up the antenna. Crazy but awesome, and I reckon so much cleaner and more efficient than a crude spark gap

The Alexanderson transmitter – The Alexander association

I'll probably try and listen in with my old external 96 kHz 24bit Sound Blaster and a long wire

If you tune in using the SAQrx software I linked above, you should already be able to see some military submarine transmissions and the like. Those stations are marked in the software.

This is absolutely awesome
