I am attempting to translate a 20khz DRM signal from its default spot

it also decimates the signal--which I do not want. I want to pass the
float input as a float until the final stage at the BlaeRF as my FM
transmitter is an all-float operation as well. Altering the signal at
all results in ruining reception of said signal. (I also like keeping
constant sample-rates throughout the graph).
Is there another way to translate frequency in GRC outside of the
all-in-one filter?
Thank you.

YOu don't *need* to decimate on that filter at all. And, I think that
you're confused about what decimation means. It has nothing to do with
data formats. It has to do with sample-rates.
