As per title really. I’m looking for a new small music player that will play MP3 and FLAC files. Preferably that takes a large SD card, otherwise has at least 128gb of storage. I want to be copying files directly on to it in a file browser and for them to play in the right order (I have a player that plays in the order the files were copied on to it, which is full on madness). I have no interest in iTunes and I run Linux as my computer OS.
Also needs to be less than £100.
And I really mean no wireless functionally at all, I don’t mean “includes Bluetooth but it can be turned off”.
But receiving FM doesn’t matter. Tons of things can receive FM that don’t broadcast, like tooth fillings.
Corporate rules rarely care about logic.
Tooth filings pick up AM, not FM. Assuming that’s even a real thing. All you need get AM is a diode which can be made to varying levels of performance with a number of common materials.
FM radios generally use superheterodyne receivers which generate a radio frequency to be mixed with the incoming signal to pull out audio.
This receiver does emit a small amount of RF as a result and it’s how the TV police in the UK would catch you for skirting a TV license.
TV licence people were never capable of detecting TV like this. They just assumed everyone has a TV but not everyone pays for the licence. So would pursue people without a licence.
They’re main detection technology was looking in peoples windows and intimidation to gain access to their homes.
