Rohde & Schwarz

Rohde & Schwarz is a German based group of companies specializing in electronics. Their main business is in measuring and test equipment, but they have produced a number of amateur radios in the 1950s and 60s. At present they do not offer any equipment specifically targeted at amateur radio operators. That said, more than a few operators will own ex-military or ex-marine R&S equipment.
