This is a rare Callpac PRC-2000 military pack radio.  It appears to be in very good condition although I have no means of testing it.  It comes from the estate of a long time collector/horder of HAM and Military radios.  He took good care of his equipment.  The shear quantity of the material that this guy had was staggering, imagine four 16 foot cargo trailers full!  I'll be listing all sorts of high quality radios and components in the coming weeks.  If you're looking for something in particular, let me know.  Please see the photos.
