I’ve written before about how it would be nice if QRP ops had a little more ooomph from time to time. I was thinking that 20 or 30 W would be a good figure to shoot for. That’s a little over 6 dB for a 5 W transmitter.
For even lower-power rigs, such as the DC40A that output 1 W, there is the Tx Topper. This amp, designed by Chuck, W5USJ, and Jim, K8IQY, provides about 5 W output.
Chuck and Jim have provided a nice set of documentation for this project. I may just have to build it once I’ve completed the DC40A kit I’m working on.
