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”.
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.
