KENWOOD TS-50S

Kenwood TS-50S is a compact HF transceiver  

 

The Kenwood TS-50S is a compact HF transceiver designed for amateur radio operators seeking high performance in a small, rugged form factor. Covering the entire HF spectrum from 1.8 to 30 MHz, including the WARC bands, the TS-50S delivers up to 100 watts of output power on all modes — SSB, CW, and AM — making it well-suited for both base station and mobile operation.
