 +====== SE-203 ======
 +** SE-203 Radiovox**; manufactured by [[Autophon|Autophon AG, Solothurn]].
  
 +In the early 1950s, [[Autophon]] developed a frequency-modulated radio system for the communication between the aircraft command vehicle (FLEIW), the aircraft guidance post (FLEIPO) and the central aircraft control. It was based on a very similar police vehicle station.
 +
 +The set saw mobile use as **SE-203/m** in the Mowag aircraft command vehicle (FLEIW) or fixed use as **SE-203** in the mountain stations as VHF relays.
