The Realistic Navaho TRC-23B was Radio Shack’s most popular 23 channel CB base station. It featured great performance for the price which, in 1976, was just $159.99. Only the basic controls, but dressed up with a large “ON THE AIR / MODULATION” display which would light up on transmit. The TRC-23B also featured a strong front-mounted speaker, headphone jack, and 5-pin female DIN microphone jack.
I had this in 1974 and I loved it. I also got rid of the stock mic,
and replaced it with a Turner powered desk mic. Loved talking on it late at night.
