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.
- introduction, Types of radio receiver
- 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

Congrats für dieses ambitionierte Projekt. Das Geheimnis von Stefan, allein
ein solches Projekt durchzuziehen, scheint zu sein, dass er es konsequent in
‘building blocks’ aufgeteilt hat. Diese hat er dann einzeln gebaut, vermessen
und schlussendlich zum grossen Ganzen zusammengefügt.
Sobald meine Drahtantenne fertig ist, werde ich Stefan um ein sched bitten. Ich
möchte schliesslich hören, wie sich der TRX ‘on air’ anhört.

Danke Peter und ja machen wir! 73, Stefan
Looking very much forward to follow this project. The nice thing about your videos is, that you are explaining the technical stuff in depth. Please keep doing that.

thanks René for the encouraging feedback!
Steps to build a ham radio from scratch. Step 1: become familiar with the various components of your ham radio. Step 2: obtain a valid ham radio license. Step 3: design and build a working circuit.
You can do amateur radio yourself. Ham radio can be built by anyone with the right tools and resources: a circuit board or a ham radio kit. Aside from that, learning how to start a radio hobby from scratch takes a lot of patience and perseverance.
