Firstly, the current gr-op25 recipe in pybombs will build a version of OP25
that's compatible only with GNU Radio version 3.7. (If one really wanted to
build OP25 for GR3.6 he could pull the old SVN repo which is still online, but
that version is no longer maintained). However (last I knew)
Hello, can anyone explain to me exactly how the XMLPRC SERVER/CLIENT BLOCK

Hi Brandon,
well, I haven't tested OP25 on neither 3.6 nor 3.7, but the changes
between the 3.6 and 3.7 class naming and module organization are the nr.

Hi Brandon,
which version of GNU Radio are you working with (`gnuradio-config
--version`)?
