The KG-46/MYK7A is a satellite telemetry and mission decryptor which first came into service in 1991. At the time it was the smallest satellite decryptor ever produced.
|This KG-46 is made by Mykotronx and is on display at the National Cryptologic Museum. The placard describing it shows it as the MYK7A which is a Mykotronx product. Hopefully the text below will link the MYK7A designator with KG-46 designator. (Photo by Ralph Simpson)|
