notes: label: Description (Brief)
content: Japanese mark 32 type military short-wave infantry radio transmitter from the World War 2 era. Unit appears to be a regenerative detector of the 1939-42 period, employing a UZ12C twin triode. This tube appears to be similar to the American 1G5G. A meter normally mounts on the right hand side of the panel, but the meter unit is missing. A three position switch on the front panel chooses desired frequency ranges. One control varies regeneration. Input voltages are 6 volts for filament and 150 for plate. Marked: Serial 102378. All other lettering is in Japanese with the exception of some electrical values on components, which are in English. Note: many markings appear to be made with radium paint so as to glow in the dark. Dr. Eiju Matsumoto examined this unit in 2004 and was unable to determine the maker. He translated the script and reported they refer to control identifications and component makers. Reference: See War Department Technical Manual TME11-227A, "Japanese Radio Communications Equipment," Dec. 1944, for identification and technical information.
