Will adding a linear amplifier to my ham station make my signal "louder"? How is this related to the S meter reading on the other guys radio? In order to understand how much difference and amplifier (linear), as used in amateur radio, would make if added to your transmitter on the air, rating and running a pair in a linear with about 66% efficiency, you're only going to get out about 100 watts. Today's generic transceiver already puts out that much, and if you're looking for an HF "brick" for a QRP rig, solid state is a better way to go.

Will adding a linear amplifier to my ham station make my signal "louder"? How is this related to the S meter reading on the other guys radio? In order to understand how much difference and amplifier (linear), as used in amateur radio, would make if added to your transmitter on the air, That means that you would need a 400W amp to faithfully AM modulate a 100W CW signal. If you have less power available, or "headroom", your amplifier will be operating in compression, which will distort the signal by "clipping" or cutting off the peaks of the rating and running a pair in a linear with about 66% efficiency, you're only going to get out about 100 watts. Today's generic transceiver already puts out that much, and if you're looking for an HF "brick" for a QRP rig, solid state is a better way to go. On the other hand, a nostalgia-driven project could be lots of fun. In retrospect based on the total number of reviews on this site and if they are an accurate indicator, statistically the 811 HF amp is the best bang for the buck in the ham community.
