Seems to be a successful attempt at allowing both:
(a) rig to control GQRX (b) GQRX to control rig There's a 0.5 second hang time whenever a given input is made, to prevent dueling inputs. The key thing appears to be, whenever GQRX sets the frequency, I need to tell the rig, but then also, tell GQRX again, so that it centers up the frequency. Other thing to note is that the frequencies are all negative. I wonder if that is actually necessary.
