I am preparing a gr-air-modes 0.0.2.c29eb60-1 which has uptream swig fixes that I expect will address this. (current gr-air-modes git HEAD)
Thanks for your interest in this package. Yes, it has caused me to learn more about swig, and this bug showed up trying to merge multiple github features along with my swig refactoring. So while that fix was upstream for a month, I got distracted by the recent gnuradio release of version 3.7.10 and my updating of all my gnuradio related packages following that. -Maitland
