====== Receivers ======
In the very early years of military wireless communications in Switzerland, the receiving equipment usually was bought together with complete wireless stations from commercial companies; these receivers were known by their commercial designation.

A few years later, abbreviations for the different types of receiving equipment were in use, usually consisting of **Exx** and the two digits of the year of introduction.

In the year 1951, a new designation scheme was introduced for all military telecommunications equipment, a few older sets still in use even got renamed according to the new designation scheme.

Since then, all receivers carry a designation following the **E-6xx** and a two digit number in ascending order designation scheme.

As an example, the "All Wave Receiver Autophon" introduced in the year 1939 initially carried the designation  **E39**, under which it is still very popular among Swiss former signalmen. After 1951, this receiver got the designation **[[E-600]]** according to the new designation scheme.

Not for all E-6xx designations, the receiver type is known today. In very few cases, a Exx-designation has been re-used for another set in later years. One of this very few examples ist the designation E-606, initially used for the american National Company's HRO, in 1965 a solid state portable radio developed by Biennophone got the same designation [[E-606]] and still can be found today in surplus shops.
