Use this plugin to record its channel IQ data in [sdriq](../../samplesource/fileinput/readme.md#introduction) format. The baseband sample rate can be decimated by a factor of two and its center shifted to accomodate different requirements than recording the full baseband. More than one such plugin can be used in the same baseband to record different parts of the baseband spectrum. Of course in this case file output collision should be avoided.

Each recording is written in a new file with the starting timestamp before the `.sdriq` extension in `yyyy-MM-ddTHH_mm_ss_zzz` format.
