A DDS Based Inexpensive QRP CW TX - A fun Arduino project

Greetings Radio People! If you like what I am doing please subscribe to the channel - I would very much appreciate your support. In this video we build on the DDS based VFO we used in the BITX video here:    • Building a basic QRP homebrew BITX - Part1   With a key shaping circuit and buffer amplifier taken from the work of W6JL: https://www.qrz.com/db/W6JL/ We can create a very simple CW TX that can drive the QRPLabs linear we built here:    • Making a 10W linear - part 1 - musings and...   I have uploaded the project files here: https://www.qsl.net/g/g0mgx//BlogFile... You will find the schematic of the RF buffer Amp and CW key shaping circuit, the Fritzing wiring diagram and the Arduino software for the Blue Pill STM32 board. If you would like a video with a detailed walkthrough of the software please leave a comment to that effect below. The STM32 boards "blue pill" are available here: the display I used is this one: https://amzn.to/2RLLfTw Rotary encoders: https://amzn.to/38WQyW3 Buying through the links above result in a small commission to the author at no cost to you. Using this link to Amazon: https://amzn.to/3dyvl77 results in a small commission on all purchases to help fund my next sensor. I hope you enjoy!
