+ | ====== SE-111: Small Decimeter Station " | ||
+ | **Small decimeter station**; manufactured by [[Hasler|Hasler AG, Bern]]. | ||
+ | In 1941, a low power radi oset operating in the UHF range was developed by the Bern based company [[Hasler|Hasler AG]] and was introduced with the troupe in 1942/3 after some problems with the early sets have been cured. Since the device with the odd-shaped antenna could only used for point-to-point - coommunication in optical distance, it was used only in isolated occasions. | ||
