What do you mean "it blows"?

tvrx_wfm_rcv_gui.py works for me.  FWIW, I've got which_side = 1.

I'm not sure what tvrx_debug is supposed to do, so I can't really
comment.

I think you're missing something.

The constructor still accepts the mux argument.  Nothing has changed
there.  The tvrx_wfm_rcv.py code should really probe for the tvrx
d'board and set which_side automatically, but absent that, it should
accept a --which argument.
