History
The TS-770 was introduced in the early 1980s as an all-in-one VHF/UHF base station transceiver. It followed earlier single-band designs by combining both 2 meter and 70 centimeter coverage in one unit. The radio supported multiple operating modes, making it suitable for weak-signal work, FM repeaters, and general amateur use.
This model was produced during the period when Kenwood branding had largely replaced Trio and Trio-Kenwood in international markets. The TS-770 became known for its versatility and remains of interest among amateur radio operators and collectors.
