DL35 - Germany special event

The DARC honours 35 years of SDR-technology with special callsign and special-DOK. In order to acknowledge the high importance of digital signal processing for communications technology in general and amateur radio in particular, a special event station 'DL35SDR' will be active from the greater Munich area throughout the year 2020. The Special-DOK "35SDR" was issued for this station.

Today, digital signal processing via Software Defined Radio (SDR) is the generally accepted standard for decoding and generating of radio signals.

Commercial services have been using this technology for a long time and nowadays amateur radio is not imaginable without SDR.

Prof. Dr.- Ing. habil. Ulrich L. Rohde, DJ2LR / N1UL, was the first to describe the possibilities and perspectives of SDR in a congress lecture at the "Third International Conference on HF Communication Systems and Techniques" in London in February 1985 (classified). The title was: "A Sampling of Techniques".

DJ2LR / N1UL, a member of DARC Amateur Radio Club Munich South (C18) is recognized as one of the pioneers of SDR technology 35 years ago.
