These rigs are mostly known for their mechanical weaknesses. Only very few are operational at present time.
I have had a working BCR 101 for several years.I use it for general SWL'ing and WWV. It works fine on ALL bands. I have had no trouble with it so far. No, I have no books on it! It's nowhere near anything available today but it works and being older technolgy, it can be reapired locally. Tom N4CYV
