    Used the famous radio amateur John Reinartz circuit (1921), featured a combination of capacitive and inductive feedback using a specially wound spiderweb coil with tapped primary, secondary, and tickler windings. The primary winding tuned the antenna and provided loose-coupling to the secondary. Once set for a particular antenna, the primary need not be changed much. During operation, the secondary inductance was the only one entering into the actual tuning of the set. Regenerative feedback was effected by a variable capacitor in the detector plate-tickler-antenna circuit. The tickler coil provided additional feedback at the higher frequencies.
    Coverage 130-2000 m band, using three various coils. Possible SW band with less coil.
    Prototype - Baltic; Stockholm, Sweden.
