A well-designed and versatile Citizens’ Band radio. The 75–820 can be configured as a hand-held unit when used with the detachable battery pack, and the optional DC adapter turns it into the smallest mobile CB you’ve ever seen. The included battery pack uses either six alkaline AA’s (not included) or eight nicads (not included). This radio features 40 channels with instant access to five user-select channels, emergency 9, and road info/trucker 19. Has a BNC antenna connector (flexible antenna included). Measures (with included battery holder) 2.75"×5"×1.25". Comes with a slide-on base/powercord adapter which takes the place of the battery pack.
