Video of my slightly modded STTE communicator. Same basic unit as the Master Replicas unit, with cheaper parts and less "finishing." I did some finishing: gold leaf on grill, attenuation on the speaker, resoldered weak battery connections, lubed and adjusted moiré disc mechanism for smooth operation and more 3D appearance, some lead weights for more realistic feel. Oh, and stripped antenna/cover down to authentic brass, OF COURSE.
Not a bad communicator for $50-80 plus a few hours of work.
Still want to get a MR unit as I understand that, though not perfect, they are superior in some of the parts.
