GENERAL DESCRIPTION OF THE HF2013DX-A AMPLIFIER
The linear amplifierHF2013DX-A is designed for all short wave amateur bands from 1.8MHzto
29MHz (including WARC – bands) and all operating modes. It is equipped with anceramic
tetrodeFU728F(4CX1500B). The HF2013DX-Ais automatically tuned to the operating
frequency of your TRX when the correct control cable is connected.
