  1. Heute in einer Woche, am 9. Juli 2026, bei Supercomputing Systems AG im Technopark Zürich findet das Embedded Software Meetup «Software Defined Radio: Intro, Fun, Testing and Profit» statt.

    Würde mich freuen, viele neue und alte Leute zu sehen, die Vorträge zu geniessen und zusammen anzustossen!

    Anmeldungen hier bitte: meetup.com/embedded-software/e

  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 had the curiosity to do some tests transmitting and receiving DMR DMO with an unmodified #plutosdr

    Normally DMR in repeater mode requires establishing a time base from the BS transmission in order to fit into one of the timeslots.

    However, in DMO mode, there is no such requirement. When starting a DMO transmission, every terminal establishes its own time base, and the receiving radio must synchronize to it.

    So DMR in DMO mode can work fine with the Pluto.

  4. A few pics with the signals right at the output of my ADALM-Pluto in the 2390 MHz band, before amplification. In order or appearance: 4FSK, DQPSK, GMSK. I don't normally use the GMSK modem due to it's slightly lower performance, it's just there to spite my D-Star-using friends. Audio payloads are Codec2 and Opus.

    The amplification chain has two stages: first to ~16 dBm, second one to ~36 dBm.

  5. Today I learnt that #GNUradio Companion (GRC) has the ability to export C++. I think that this means that I can compile the C++ and run it natively on a #PlutoSDR.

    Time will tell what the gap between theory and practice is :)
