Rf filter audio recorder (Techniek Radio/TV)

Volgens mij ligt 105,025 MHz bijna net zo ver in de sperband van goede audioapparatuur als 105,175 MHz.

Dat is op zich een valide uitgangspunt maar TS zit met een erg grote veldsterkte.
Die zal zodanig groot zijn dat detectie al 'zonder afstemmiddelen (en/of mixers)' plaats kan vinden. De benodigde 'diodes' zijn er genoeg te vinden in de audio-apparatuur en dan is i.c.m. met de doorlaat van die apparatuur een flankdetector geboren.

Vr. groet, Ron
