See how an Arduino can be transmit music over AM with only a few lines of code.
A complete AM / SW / SSB / FM RDS Radio Receiver, with Si4735, Arduino NANO and 1.8in TFT Display.
Add an external S-meter on any Icom amateur radio transceiver that has a CI-V control port.
Attach an amateur radio to this and the radio will regularly identify itself so others can use their direction finding skills and locate it.
Sensitive retro look radio capable of receiving signals from middle wave and short wave band.
Embellish, protect and reduce the sheet metal look of your modified HP server power supply with this 3D-printed enclosure.
Radio that works with analog signal is implemented digitally on FPGA via VHDL.
Now the Radio has new firmware from Gert Baak with more visual and functional improvements. Also used Si4732 chip.
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.
I made a brief comparison between these two SDR radios. Small Chinese SDR receiver will meet the needs of every radio listener, especially
A very simple and easy way to enter the world of DX communications without learning Morse code
This device is especially useful for HAM radio beginners, and also SW listeners who can monitor CW communications without knowing Morse cod
This project walks through how to get started with the RTL-SDR on Mac OS 14
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.
Build a 12/24 hr UTC digital clock using low-cost TM1637 4-digit displays and a Raspberry Pi Zero W.
A simple way to build a quality multiband receiver using a specialized radio chip.
The "Rescue Repeater" is a drone-based radio repeater solution to allow communications to be rapidly restored or extended over the horizon.
RTL2832 dongles were designed to receive DVB Digital Video Broadcast signals. We need to install a driver to use SDR Software Defined Radio.
In this way, we can also decode many digital radio signals such as Weather Fax, Slow Scan TV, and many more
How to make a relatively simple All band DSP Radio Receiver with color touch display which is based on the Si47xx series chip.
This miniature module has amazing possibilities, great sensitivity and selectivity
