A complete AM / SW / SSB / FM RDS Radio Receiver, with Si4735, Arduino NANO and 1.8in TFT Display.
See how an Arduino can be transmit music over AM with only a few lines of code.
Easy-to-build VFO (Variable Frequency Oscillator) that features a clear, touch-enabled circular display with retro-style virtual scales.
Add an external S-meter on any Icom amateur radio transceiver that has a CI-V control port.
Sensitive retro look radio capable of receiving signals from middle wave and short wave band.
Attach an amateur radio to this and the radio will regularly identify itself so others can use their direction finding skills and locate it.
Embellish, protect and reduce the sheet metal look of your modified HP server power supply with this 3D-printed enclosure.
This project implements an Amateur radio operator-oriented clock with features intended to help in the Ham shack or portable operations.
Now the Radio has new firmware from Gert Baak with more visual and functional improvements. Also used Si4732 chip.
This device is especially useful for HAM radio beginners, and also SW listeners who can monitor CW communications without knowing Morse cod
Radio that works with analog signal is implemented digitally on FPGA via VHDL.
A homemade semi-automatic antenna tuner for HF controlled by an Arduino Nano.
Remember the days when you would sit listening to WWV time signals on your shortwave radio (tick, tick, tick…At the tone, the time will be…)
How I converted a 1970s vintage receiver into a contemporary WiFi radio, whilst keeping all the original looks and features.
A very simple and easy way to enter the world of DX communications without learning Morse code
I made a brief comparison between these two SDR radios. Small Chinese SDR receiver will meet the needs of every radio listener, especially
This project walks through how to get started with the RTL-SDR on Mac OS 14
RTL2832 dongles were designed to receive DVB Digital Video Broadcast signals. We need to install a driver to use SDR Software Defined Radio.
How to make a relatively simple All band DSP Radio Receiver with color touch display which is based on the Si47xx series chip
The radio presented above is capable of receiving the entire spectrum, from 500 kHz to 2 Gigahertz.
A simple way to build a quality multiband receiver using a specialized radio chip.
Build a 12/24 hr UTC digital clock using low-cost TM1637 4-digit displays and a Raspberry Pi Zero W.
The "Rescue Repeater" is a drone-based radio repeater solution to allow communications to be rapidly restored or extended over the horizon.
In this way, we can also decode many digital radio signals such as Weather Fax, Slow Scan TV, and many more
