-[[Autophon]] got an order to develop an allwave superheterodyne receiver in 1938 and developed the **E39** receiver, based on their surveillance and measurement receiver RD2679. The concept of a receiver with a triple main tuning condenser and plug-in coil sets with calibrated frequency charts was based on National's HRO receiver. The core component, the triple - tuning condensator PW-3 with the micrometer dial typical for [[National|National's receivers]], has been acquired from that manufacturer in the USA.+[[Autophon]] got an order to develop an allwave superheterodyne receiver in 1938 and developed the **E39** receiver, based on their surveillance and measurement receiver [[de:rd-2679|RD-2679]].

-Autophon developed their control receiver [[RD2679]] in 1937 and got a contract to develop the communication receiver **E39** for the Swiss Army in late 1939. It's principle was based on [[National|National's]] [[HRO]] receiver with very similar plug in coils and calibration charts. The main component, the triple tuneable condensor PW-3 mwith it's characteristic "Micrometer dial" was acquired from [[National]].+Autophon developed their control receiver [[de:rd-2679|RD2679]] in 1937 and got a contract to develop the communication receiver **E39** for the Swiss Army in late 1939.
