Thanks Dave, yes, I too am a little surprised as to why nobody cares to supply a fix, a workaround, or even a hint as why this is going on. I put the exact same post in the gnu-radio homebrew forum and the moderated closed the thread; I am not sure why because he wouldn't answer me but he closed it. Ive posted this question in so many places with but no luck so far.
As a workaround I removed the block "wxgui_fftsink2", as that block is not integral to the signal processing. And that is the goal of "op25_grc.py", to decode digital radio signals. This code block is run in GNU radio companion (GRC) along with many others in the signal processing path . GRC is a GUI where one can manage the code (ie. use a flow graph instead of coding) needed to process radio signals with a personal computer; sort of like the IDEs people use to create executables. One can create there own processing blocks or use blocks that others have created.
Thanks for your cooperation and patience! I am going to keep working on this as time allows.
