Hey Adrian,
anything that touches rate will go through cores/rx_dsp_core_200.cpp.
This has a function, get_host_rates(), which will not include the rate
you want. Modifying this function should get rid of this error message.
I don't know exactly what you changed on the FPGA, but note that setting
a decimation of 1 (or 'no decimation') will also disable all filters.
Cheers,
Martin
