This project and your efforts will provide you with a 0.55…3 watt input to easily 10 watt output. The two linear amplifiers are ment for use with QRP SSB/CW/FM/AM transmitters on the amateur bands 15 and 17 meters can be powered from a 12 volt DC supply. The design is a good balance between output [...]
The best place to put a pre-amplifier is with out a doubt as closest to the antenna as possible. If possible, directly mounted at the feeder (dipole) and using phantom-type powering of the amplifier. The RF/DC splitter comes inside the shack just before your receiver. Keep the connections as short as possible @ RF IN [...]
