Manufactured by Sangean, Taiwan.
In 1996, Sangean presented an exceptionally sucessful receiver: the ATS-909. The almost identical set has been sold in Germany as Siemens RK 777; as the price tag of the receivers with the Siemens brand was much higher, then the Sangean original, only quite few sets have been sold.
A while after Siemens withdraw from the domestic radio market, the Sangean receiver was imported and sold as Technisat ATS-909 which was a quite popular set in Germany over many years.

The set is equipped with semiconductors.
The set was developed in Taiwan and sold in Germany as Siemens RK 777 and in the USA as Radio Shack DX-398.
