====== Swiss Army receivers ======
{{ :logo:switzerland-logo.png?120|}}In the early days of radio communications, receivers produced by [[Telefunken|Telefunken, Berlin]] were mainly procured for the Swiss Armed Forces. With the advent of World War II, more Swiss-made equipment was introduced, such as superhet receivers from [[Autophon]] and [[Zellweger]].

Surveillance receivers were acquired in larger numbers, and high-quality communications receivers were purchased in small numbers for interception services and radio surveillance.

===== Nomenclature =====
In the early days, receivers were designated by an abbreviation **Exx**, **E** standing for receiver and the number for the year of introduction.

In 1951, a new nomenclature was introduced in the Swiss Army. Receivers were henceforth given the designation **E-6xx**, and the devices were numbered consecutively according to chronological order. The receivers still in service received a new designation according to the E-6xx nomenclature in addition to the old one.
