Drehko u. Variometer auf einer Achse: durchstimmbar 180-700m (mit LW-Zusatzspule 1800-2800m; siehe Bild); dieses Prinzip wurde später von Telefunken (noch später auch von Siemens) verwendet . Lizensierter Nachbau "TELEFUNKON D" bzw. "E304" mit kleinen Abweichungen (metrische Gewinde, andere Übertrager und Bauteile etc.).

Einschlägige US-Patente: 1,502,848 und 1,515,186, sowie 1,667,863 und 1,572,877. Sie beziehen sich auf die Einzelgeräte RA und DA, die in einem gemeinsamen Gehäuse die Bezeichnung RC tragen (ab 1921/22).

Tuning by variable condenser and variometer coupled on a single shaft; 180 to 700 metres; (with load coil 1800 to 2800 metres; see photo); This principle used later by Telefunken for the "TELEFUNKON D" or "E304" which was a licensed copy of the RC with minor variations e.g. metric thread / different audio transformers / slightly different tube socket sleeves / different capacitors and resistors;
