In the early years of wireless communications, the Swiss Army mainly relied on German made equipment constructed by Telefunken or Lorenz.
The very early sets have been installed on horse-pulled trailers, later sets came installed on lorries. Portable sets that could be carried usually by several men have been added in the thirties.
You will find much more informations and images in the book "Die Funkertruppe" written by Col Rudolf J. Ritter, I got most of the following informations from his books - but they are written in german language only.
I hope to add images showing You the wireless sets, later.
