  1 Atwater Kent refused to take a license on RCA´s reaction patent which would have been about 100,000 USD p.a.;A.-K. instead offered this supplementary variocoupler separately and the dealer or the customer could complete the set if so desired.

  1 1 Kreis ohne Rückkopplung, jedoch konnte der Händler oder Kunde einen Variokoppler zur RK hinzufügen (mittleres Bauteil). Atwater Kent weigerte sich, Lizenz auf das RK-Patent bei RCA zu nehmen (ca $100.000 pro Jahr!). Deshalb diese vorbereiteten Sets.
