The TS480 is an all mode HF plus 6 meter amateur transceiver. It features AF digital signal processing on both receive and transmit. A quad-mixer provides receiver dynamic range equivalent to that of the TS-950 class. Receive coverage is 500 kHz (30 kHz VFO) to 60 MHz and direct frequency keypad entry is supported.

One of the unsung heroes of smallish HF+ rigs, the Kenwood TS-480 isn't however a competition-class radio, but it is a good-performing little rig, better than most of the similarly-priced radios. The receiver is (apparently) better than the 480's big brother, the TS-2000. It has very good computer control capability, and it is designed to be good both base and mobile/portable, with a control head that is neither too big nor too small.
