Re: LF: EbNaut and The Cat / Take 3

.. and you can hopefully soon add one more unique RX setup to the list:

SDR-IQ with OCXO-locked 66.666 MHz oscillator + SpecLab with wave file recorder tapped at the decimated input to the FFT (this function is new, it has not been uploaded yet.. and not successfully been tested so far. Keeping fingers crossed. Trying to tame my old TS850's main oscillator was not successful.)

Cheers,

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.

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!
