Studio & Engineering
Shortwave radio technology is where we share the practical side of Radio Delta AM — what we build, what we test, and what actually works on the air.
From transmitter design notes and antenna experiments to audio processing chains and studio setups — this section is for listeners and builders who like to understand the “how” behind the sound.
If you receive our signal, you can send a reception report and learn more about Radio Delta AM.

Our Transmitters
Design notes, build stories and test results from the transmitters we use on shortwave and AM — from vintage hardware to modern solid-state designs.
Explore Transmitters →Our Antennas
Antennas, radials, tuning methods and real reception results — what works in practice, and why.
Explore Antennas →Audio Processing
Audio processing chains, settings and sound experiments — from clean AM to punchy shortwave audio that survives long-distance propagation.
