osmo-fl2k for using USB 3.0 VGA adapters as SDR transmitters

Added by laforge 5 months ago

On April 22nd, Osmocom developer Steve Markgraf has released a new Osmocom project called osmo-fl2k during OsmoDevCon2018.

osmo-fl2k allows you to use the DAC contained in Fresco Logic FL2000 USB 3.0 VGA adapters as a SDR transmitter. Rather than rendering video signals to a screen attached to the VGA output, the DAC is used to generate RF signals in base band, possibly relying on the harmonics to achieve signals at much higher frequencies than possible at 165 MS/s in base-band.

The project thus follows the spirit of the earlier rtl-sdr project, which re-uses USB DVB receiver dongles with the RTL2832U chip as SDR receivers. Like-wise, osmo-fl2k creatively re-uses USB 3.0 VGA adaptors as SDR transmitters. The two projects are thus complementary.
