Could you please clarify whether its a Standalone SDR or one should interface with the previous version of LIME-SDR
@Tony - Tony,
It’s a companion board that plugs onto the LimeSDR and up/downconverts the Lime’s receive and transmit paths. Think of it like a outboard up/downconverter or mixer. I would also think that data communications to it to tune will be from the LimeSDR API from the Lime itself.
