Produced by various U.S. manufacturers.

The high-performance AN/GRC-26 radio teletype station was used by the U.S. Army in different configurations and was also used by the German Armed Forces after 1956. In addition to a transmitter, the station equipment included two receivers and two teleprinters with the necessary accessories, which were usually housed in a shelter on a lorry.

The predecessor station in the Second World War was the SCR-299 / SCR-399 radio station, which was introduced in Switzerland as SM 46 or SE-402.
