  1. I've just tested the principle of processing using Controlled-Envelope Single-Sideband modulation (CESSB) in and it is beyond beautiful.

    It uses a two stage process of clipping and peak stretching that combined can reduce the effects of over modulation typically introduced by

    Even extremely overmodulated input signals (25x) still produce clean audio indistinguishable from the original source signal.

  2. Contributed my first patches to the amazing vrt-iq-tools:

    github.com/tftelkamp/vrt-iq-to

    With these you can stream IQ sampling data from SDRs over the network, supporting many interesting use cases. Including multiple concurrent users, integration with GNURadio, conversion to a Soapy device and even things like a correlator.

  3. I was able to reconnect with #hams from #maryland and people I met at #hamsci, #cedar, #hamvention and #gnuradio conferences. Some folx I haven't seen since the #pandemic! It was good to be out and about. Everyone was cool but no one who was still working wanted their photos shared on #socialmedia because they were concerned about security issues and fear of a #facist planet. This is what it has come down to. SMH 4/4

  4. HackRF + GNU Radio = WBFM Transmitter

    Продолжаю цикл статей посвященных легендарному HackRF. В этом материале я хотел бы разобрать изнанку GNU Radio и описать широкими мазками то, каким образом оно устроено под капотом и сделать какой-нибудь минимально интересный проект с его использованием. Для себя я выбрал простую передачу аудиосигнала с микрофона с одного HackRF на другой через коаксиальный кабель с использованием OFDM-модуляции. Посмотрим на созвездия, спектр, принимаемый сигнал во времени и по частотам. Добро пожаловать под кат, будет интересно! 🙂
