DIY HAM radio transceiver

Hi all,

I did build my first ham radio transceiver and I thought I let you know how I did it.

This might give you ideas about your own HF experiments and give me some feedback from you guys and ideas for new projects.

• antenna amplifier
• bandpass and lowpass-filter design
• mixer and modulator/demodulator
• crystal ladder filter
• audio amplifier
• microphone amplifier and two tone generator
• power pre-amplifier
• power-amplifier
• Fast Fourier Transformation, FFT
• touchGFX application on the STM32H735DK
