AX.25 and USRP? gr-multimon?

GNU Radio
1

Hello,

Does anyone know of any code for the USRP/Gnuradio to decode AX.25
packets? I’ve seen threads of this conversation from several years
ago but can’t seem to find any code to implement this. gr-multimon
seems to be a tool that might do it, but I can’t find it anywhere.

Thanks for your help.

Dear Firas,

I have been working on this, but cannot get it to compile on my Mac.
The error is:

/usr/local/lib/libgnuradio-core.dylib(single module) definition of
_fftwf_ct_uglyp
/usr/bin/ld: multiple definitions of symbol _fftwf_hc2hc_mkcldrn

/usr/local/lib/libgnuradio-core.dylib(single module) definition of

make[3]: *** [all] Error 2

Any ideas?
