This article describes the details of the design, which can be easily scaled for just about any HF band. The antenna described in this article is for the 20 meters band.
This module is an analogue and digital SWR and power meter/monitor, designed to replace analogue SWR and power metering in an AM Transmitter project.
An experimental antenna for HF reception. It consists of a single loop element mounted on the ground. It is stealthy, small, and quiet. EZ-NEC plots and on-air test results are included.

While there are quite a few standalone Morse Code or CW decoders out there, I wanted to tackle the problem myself and end up with both a great Arduino learning project and a decent portable decoder for when I’m out in the field operating QRP
