Hi Eric,I have not looked at tunnel_ip_null_mac. I went through the others. What I am trying to do is identify the gnuradio blocks I will need to use to convert a character stream from a file into signals that can be sent across the SMA cable to the rx side, where it can be decoded and written as a

OK, Let's try this again ;) I've fixed the tarballs such that the output of swig is no longer in them. This ensures that all modules will be built using the version on swig on the build machine. Please let me know if you run into any problems. The new tarballs are at ftp.gnu.org: gnuradio-c

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. -Clark Fro
