VHF Band III baseband player (sender)
For crc-dabmod released by CRC, which did not yet contain an integrated UHD output, a baseband player is required to use the USRP Software Defined Radio platform. The baseband player sends the stream to the SDR device, and defines additional settings like transmission frequency, DAC sample rate, gain and other parameters.
