Assorted ramblings from the developer


LimeSDR Transmitting
LimeSDR Transmitting

I spent a day working on transmit support for the LimeSDR. This is by no means finished, but I'm able to say that it works. I have a few problems,

  • Big spur at 0Hz, probably generated by a bad software mixer,
  • Noise bursts when switching from receive to transmit. 

The above are down to my own software, so I'll give myself a good kicking sometime and get this fixed later in 2017 or early 2018.

Here we see the Upper Sideband (USB) signal as received with an Airspy HF+.

And here's the TX panel from SDR Console.
