In 1976, Sony introduced CRF-320, which is a high-priced portable world-band receiver. As the price exceeds DM 4000, it has not sold much, but its performance in shortwave band is still comparable to that of today's receivers. CRF-320A is the receiver that many people dreamed of in the 1980 s, so now it is left (thanks for the model come from: Wassup_)
