But it's not just interference I actually hear the audio coming from the speakers in the headphones of my radio.

So the DAC in my tablet propagates audio via am radio waves?

>>8820503
no, there can be interference between both dac's or you are just making it up
also neither you or i know the circuts of both devices so it's hard to tell. maybe there is some electronics fag to explain it deeply enough

>>8820519
I'm not making it up I've just been noticing it for a while and it's been bugging me.

>>8820527
is this electronic pocket radio?

>>8820527
or better question is it using DAB ( https://en.wikipedia.org/wiki/Digital_audio_broadcasting ) or not

>>8820531
Um yes I guess? It's an old am/fm pocket radio from like 2001.

>>8820547
it can be just dac-dac interference or interference between tablet speaker and not protected audio jack in radio(which is more possible and i don't know why i hadn't thought about it before)

I have a pocket radio I hear interference when I flick a light switch on/off. Why is that?
