Another of Radio Shack’s very basic but popular CB radio was the Realistic TRC-468. This model featured all 40 channels, but no frills. Not even a digital channel display or a S/RF meter. Regular price was $99.99, but frequent sales brought it down to $69.99-79.99. Introduced in 1977, this was the 40 channel replacement for Realistic’s TRC-68 “Mini 23.”
