What can I do to minimize electromagnetic radiation from power amplifiers?

[Chromatischism]

The wavelength of 100khz is 3 kilometers.

Are you sure about that?

 

[solderdude]

yep, 100kHz = 3km.
1/4 wavelength = 750m

Handy link, thanks.

One would need to measure in the proper conditions (EMC lab) to get accurate readings with far more expensive equipment.

I don't think it's a good idea to wait until we make a lot or money or wait for EMC lab. I like taking matters into my hands.
0.1V/m resolution is fine enough. It is far better than nothing.

It's still better to have relative readings through a radio than to have nothing. Sound signatures give me some ideas.

If you are worried about your precious equipments, you can buy oscilloscope and measure your house wires.
Oscilloscope measures dirty electricity in house wires. I'm interested in what's actually emitted in the air.
Things like SineTamer can lengthen lifespan of your electronics and also your own lifespan.

I recommend using https://shungite-c60.com/shungite-emf-protection-proof-and-stady/ as a good way of anti-radiation protection. Been using it for quite a while, the mineral is able to purify and mineralize the water and make it completely safe for usage.

In order to shield something, especially HF, you would need to cage the total room around you and no wires can go in and out of that room without having extreme filtering at the point where the cables enter that room.
It's VERY safe to say this does NOT do anything at all.

Do you doubt me ?

Do you have radio and cell phone reception ?
When you hold the shungite stuff against your phone is the reception less or more ?

Wrap your phone in alufoil... now try to ring it.
Do this with the shungite .. normal reception ... so ergo.. all it does is empty your pockets and make you believe it does something.

ooh, now, there is a good assay!
Not perfect, though, as it would need to cover a very broad range of frequencies to be definitive.
Because, let's face it, the only part of the whole EM spectrum one really cares about are the frequencies that are causin' one trouble.

Shungite must have been taking lessons from Audioquest

The entire page using centred text is an immediate red flag.

It's interesting how the Shungite starts with basic electronics (simplified) and slowly deteriorates into total nonsense.
