[21 Photographs of Radiolänkutrustning RL-41]
$250
n.p.: Siemens Corporation, [1960s]. 170 by 120mm (6¾ by 4¾ inches). Collection of 21 original silver gelatin photographs by Siemens Corporation of their Radio Link Equipment RL-41 and components along with an interoffice transmittal envelope.
The RL-41 radio link equipment was used in the late 1960’s and early 1970s for radio connections with “pule phase modulation in the frequency of 1700 to 2300 MHz.” This RL-41 is the Swedish edition “Radiolänkutrustning.” That model was used by the Swedish Air Force for communication with its fighter planes (and presumably sold to other government agencies and major corporations in Sweden).
