Rf filter audio recorder (Techniek Radio/TV)

De technici meenden dat het radiosignaal een gedemoduleerde AM kan zijn?
Dus FM als Amplitude modulatie naar audio?

Alles kan.. een halfgeleider/buis kan als diode of ander niet lineair component een RF signaal onbedoeld omzetten in iets hoorbaars. Dat RF kan zelfs via de luidsprekerkabels naar binnen sluipen.

Maar dan moet dit RF signaal van voldoende sterkte zijn.
Afstand tot de zender is daarbij belangrijk. woon je dicht bij de inslaande zender?
