Focusing on HF

Raising power output and adding an antenna tuner are both moves in the right direction, but limiting the transceiver to the HF bands when the mainstream nowadays is HF~V/UHF would seem to be going against the tide of the times. Yet opting for the multi-band route inevitably leads to larger dimensions and higher prices. In this genre, price is an important factor, so by limiting the TS-480 to HF, we developed what is in fact a compact transceiver that stands apart from the competition. The TS-480 is designed to ensure not only excellent TX performance but also superior RX performance.
