Why is this needed?

Please end all phases on #t (or #true).

I suggest putting the lists on a new line.

Please remove the leading “A”.  (guix lint should complain about this.)

> +    (description "redsea is a lightweight command-line FM-RDS decoder for
> +GNU/Linux. Redsea can be used with any RTL-SDR USB radio stick with the rtl_fm
> +tool, or any other SDR via csdr, for example. It can also decode raw ASCII
> +bitstream, the hex format used by RDS Spy, and audio files containing
> +multiplex signals (MPX).")

Please remove “for GNU/Linux”.  Please use double spacing.  Could you
please use @dfn{} to define a few of these abbreviations?  The first use
of SDR could be “@dfn{software defined radio} (SDR)” etc.

I would do this for you, but as this depends on liquid-dsp, which needs
some clarifications, could you please also send an updated patch for
this package?

Thank you!
