A strong combination: State-of-the-Art SDR transceiver Zeus ZS-1 and digimode software FLDIGI. With a step-by-step instruction, the combination of both with audio in/out, keying and freqeuncy transfer is easy.
With software-defined radio or SDRs, also ham radio has made a considerable leap forward. SDR transceivers are around for many years but failed to have a major impact until now. Among these transceivers, Russian and German-made Zeus ZS-1 is an outstanding example, covering each amateur radio band from 160 m to 10 m with up to 15 watt output. It received enthusiastic reviews around the world, e.g. by RadCOM of RSGB and QST of ARRL with excellent ratings.
Recently, I again bought on ZS-1 to re-vitalize my amateur radio activity with also again a focus on QRP and digital modes. For this purpose, ZS-1 with its outstanding clean signal under transmit and Receiver plus tidy interface is almost ideal. BUt Ehen I needed a fool-proof instruction to set up the combination of ZS-1 and a multimode software like FLDIGI, I didn’t found what I need: a step-by-step approach.
This was the reason for writing such an instruction by myself. I concentrate on the combination of ZS-1 and FLDIGI which in a PDF is laid out in detail and with instructive screenshots. In an appendix, I go also through some other digimode software like FreeDV and EasyPal. To my own disappointment, I couldn’t get work WSJT/WSPR. So your help is very appreciated!

It’s only in late 2015 that the first SDR transceiver of one of the big japanese players hit the market. Until then, there never had been even a receiver of this kind from these sources.
Technological progress seems to come from the edges, from Russia, Italy, Switzerland, and the U.S. For many decades, hams do have their difficulties in accepting new technologies and techniques – may that be the use of SSB, CW as a mandatory, the PC or advanced digimodes.
The majority of them remains stunningly conservative. And their media lives a role model which they simply follow.
The advent of the IC-7300 reminded me of a paper, written originally in German, already in 2007. There I tried to explore this attitude. It also tracks the way of professional technology, of which ham radio technology increasingly slower lagging behind it.
Adam Farson (VA7OJ/AB4OJ) did a great job to vividly translate the text into English, read it here.
Warum sind die Funkamateur nur immer so konservativ? Das fragte ich mich zuletzt 2007 angesichts ihrer Skepsis gegenüber der SDR-Technologie. Daraus entstand eine Analyse, an die ich mich anlässlich der Ankündigung des IC-7300 im Herbst 2015 wieder erinnerte.
Hier ist sie auf Deutsch nachzulesen, und immer noch erschreckend aktuell.
