EKD-500 DDR Communications Receiver - under construction The EKD-500 was a high-end short-wave (SW) with digital readout, developed and produced in 1986 by in (East) Berlin, during the days of the former DDR (East Germany) and the Cold War. The receiver was the successor to the EKD-300 and covered 14 kHz to 30 MHz. It was complemented by the. The EKD-500 was a double conversion receiver with IF-frequencies at 70.2 MHz and 200 kHz. It had a digital frequency readout with an accuracy of 10 Hz and was suitable for the reception of AM, USB, LSB, CW, FAX and ISB signals. With a sensitivity of less than 0.5 µV at 5 MHz it was a truely professional communications receiver. The receiver was available in a grey civil variant and a green/black military one.

Receiver Ekd 300Models EKD-500 is the name of this receiver family, but the actual design variant is determined by the number at the back of the unit. The units differ in frequency range, IF filter and SSB filter. • EKD-511, Range 14 kHz - 30 MHz, IF filter 5 kHz, SSB filter 3 kHz • EKD-512, Range 14 kHz - 30 MHz, IF filter 8 kHz, SSB filter 6 kHz • EKD-514, Range 10 kHz - 30 MHz, IF filter 5 kHz, SSB filter 3 kHz • EKD-515, Range 10 kHz - 30 MHz, IF filter 8 kHz, SSB filter 6 kHz. Diversity reception When two EKD-500 receivers are available, it is possible to connect them together in a diversity setup, allowing the strongest of two signals to be selected.
