You may be able to find an existing weatherfax decoder that can be ported more easily. This worked for the multi-mon project. Somebody just took the dos code that had been around for a while and got it to use data from the gnu radio instead of a sound card like it did originally.

Subject: [Discuss-gnuradio] missing functions in gnuradio?
Date: Sat, 15 Apr 2006 11:03:23 +0200

Hello,

I am relatively new to gnuradio and plan to write a weatherfax decoder
in gnuradio.

I want to try different schemes for decoding the signal (coherent /
noncoherent / short-time DFT)

As there is phasing in the signal I am most interested in the
non-coherent approach. But there I am really lacking a square-root block
in gnuradio. It should not be difficult for me to implement it - but I
wondered why such a block is not present in the library.

Should such a block (or a general "power of" block) included in the
library?

Best regards,

Horst
