The reason is that we experience no loss when using file source/sinks but
experience loss using coax, which might be due to timing errors introduced
by the hardware.
I’d greatly appreciate any help.
Thanks!

mu specifies the point between two samples that you want the
interpolated value of. It’s in [0.0, 1.0]. It’s the input to the
gri_mmse_fir_interpolator. The rest of the parameters are for the
control loop.
