High-power 3-500 HF Linear Amplifier

摘要

Alinear amplifier is not strictly necessary on the HF bands from 18MHz upwards, and can often be-dispensed with. However, high power is often desirable or necessary on the 14, 7 and 3.5MHz bands because of the congestion and high levels of interference. Although I am not a dedicated country chaser or contest operator, I often use a linear amplifier on those bands merely to remain competitive.
