I cannot find a reference to this radio anywhere, and I'm usually
pretty good at digging up research.  What is this thing?  ends pretty
soon too.

I recently also purchased a very rare National Panasonic radio: the R442B, of which very little is known. This radio has continuous coverage in 4 bands going from .53-26Mhz. The radio was made in Taiwan (Sangean?), and has a "box type" pull-up loop antenna for reception. There is no FM band. Using only the supplied loop antenna, this radio is very sensitive. It operates from either multi-voltage AC or 4 D size batteries. I believe the radio is circa 1970 as the frequencies are labeled in Mhz rather than MC. The radio has controls: On/Off power,AC/Battery,High/Low tone, Band selection switch,Volume control, Main Tuning and fine-tuning controls I also believe because of the radio's high sensitivity, that it was made for such countries as Australia before they installed FM broadcasting. Can someone tell me more about this radio and also how I can upload a photo for all to see? In all, this NP radio is of very unusual design vis-a-vis the typical designs produced by NP in their various portables. Thanks for any help.
