NorCal Miniboots

 CW/SSB 10 Watt 20/30/40m Linear Amplifier, based on Norcal design


The files below are the instructions for building a 10 Watt CW/SSB amplifier capable of raising the output from a ~1 watt transceiver to 10 watts. It is based on the Norcal Miniboots design and contains an RF sensing T/R switch, multi lowpass band switching, and biasing circuit for SSB linear operation. We will not be offering it as a kit, however it is easy to build and the pcb Gerber files are offered here so you can source your own boards.
