Overview

The product is a shortwave receiver, specifically the EK 07 D/1 and EK 07 D/2 models, which can be used as operational and monitoring receivers in both fixed and mobile radio stations. It is particularly suitable for large stations with challenging reception conditions for commercial telegraphy and telephony transmissions. The receiver is capable of receiving amplitude-modulated signals and, with additional equipment, can also receive frequency-modulated signals and single-sideband transmissions. Key features include high accuracy, high scale resolution, selectable intermediate frequency bandwidths, and the ability to be remotely controlled over long distances. The EK 07 D/1 and EK 07 D/2 differ only in the type of coaxial connections on the back. The manual covers the device description, operating instructions, maintenance, and safety measures.
