|2304 is one of those bands where you can find some
surplus components to build with.
uses two 60w Spectrian amplifier boards with the usual input and output
hybrid coupler and combiner.
Spectrian amplifiers and their components can be found
in the usual online auctions, and occasionally offered as surplus
These two amplifier boards are not terribly efficient,
requiring a total of 26a @ 26.5v at full output, or almost 700w in for
120w out. But they do the job.
A Dow-Key high-power transfer switch handles the
changeover, and is controlled by a sequencer in the driving transverter,
which is pictured below the amplifier in this photo.
