In this episode of The Art of Engineering, we make the Cheap Chinese miniPA amp multiband HF across 10 bands via the homebrewing of a LPF board. This enables the Hermes Lite II SDR to operate from about 20-40 watts on these bands. I show the build, the guts of the build and manage some QSO’s too! 73 de VK2AOE.
