Realistic was a brand produced by RadioShack, a division of Tandy Corporation, to market audio and video products for home use. The brand name is no longer in use by RadioShack and was largely discontinued by the early 1990s. The brand was officially discontinued in 2000 after RadioShack entered an agreement with RCA to market their products.
In the early 1990s, the Realistic brand began to change its name to Optimus, a brand of speakers RadioShack had been offering since the 1970s. Both Realistic and Optimus brand names were later retired.
The Realistic DX-60 is an AM-mode only device. The radio receives 3 MHz to 27 MHz AM shortwave in three bands, 26.965 MHz through 27.405 MHz HF CB in one band, 540 kHz to 1620 kHz standard AM broadcast in one band, and 87 MHz to 108 MHz monaural standard broadcast FM. The radio existed in two versions, model 12-764 and a nearly identical but production-cost-reduced 12-764A.
