Actually, each station operator is using his own unique home-grown setup:
Transmitters,
Andy: DDS with phase ramp, dedicated controller software
Domenico: GPS-locked SSB exciter, SpecLab tone with audio ring mixer, ebnaut-tx with GPS time
Joe: OCXO-based DDS, XOR modulator, Arduino controller with dedicated Software, HF time signal
Markus: Rubidium with decadic synthesizer, ring mixer, ebnaut-tx with NTP
Receivers:
Andy: homemade GPS-synchroneous IQ sampler, dedicateed capture software
Domenico: GPS-locked SSB Receiver, soundcard with SpecLab opds FFT export, GPS samplerate tracking
Paul: direct-sampling fast ADC with GPS injection, dedicated Linux software
Markus: Rb-locked SSB Receiver, soundcard with SpecLab opds FFT export, Rb samplerate tracking.
73, Markus

At least with EbNaut nobody can complain that the operator is just installing the software and pressing 'start'. It does seem like that with some modes: the computers are doing all the communicating and the operators are merely spectators. Clearly not the case here! ... |
