Thanks, Lex, for that 3D-printed knob design. I was lucky enough to find an original knob on eBay. Also, thank Cesar for your reply. This is one neat radio. I am researching a suitable AM transmitter to get more out of the one AM channel. I might consider building one from scratch and looking into a loop antenna for the USB and LSB. Does anyone know if this receiver had a transmitter that went with it, like the FT-101 FR-101? Or was this just a stand-alone unit?
