Peter Scott (OZ2ABA) and myself gave a presentation at the 2018 AMSAT UK colloquium about the avionics in the Copenhagen Suborbitals Nexø II rocket. This included the radios and the DVB-S2 video transmitter used on the rocket. A video recording of the presentation is now available on the AMSAT UK YouTube channel, thanks to BATC.
