osmo-fl2k: USB VGA dongles and SDR
04-22, 15:00–15:30 (Europe/Berlin), Main Room

The osmo-fl2k project [ab]uses USB3 VGA adapters as ultra low cost SDR transmitters

There are some modern USB3-VGA adapters which don't have a frame buffer internally, but which are basically only USB-attached DAC, where each pixel of each frame is sent from main memory.

If we disable the back/front porch to get a continuous flow of samples, we can use the DAC[s] not for generating a video signal, but for generating radio signals.
