This sketch will read RF power and SWR from any SWR bridge, designed to work on VHF UHF bands

Ham Radio applications with the Arduino micro-controller presentation

This project describes an ARDUINO based automatic antenna tuner, for an end-fed half wave (EFHW) antenna, working on 20 & 40 meter bands

A DDS VFO using the Arduino Uno platform

This Arduino project decode ICOM CAT frequency information and switch antennas according to preset values. RX and TX antennas can even be different, a project by ON7EQ

An Arduino APRS project based on the real time OS BeRTOS

A controller for the miniVNA using an Arduino UNO and touch screen color graphic LCD display

HamShield is a powerful VHF UHF transceiver that lets your Arduino talk to far away people using ham radio bands

This project hereby presented is a complete HAM radio simplex 'smart' repeater, built around a Motorola GM-350/950, Arduino NANO board and a WINBOND audio recording integrated circuit

Yet another Arduino CW Decoder based on the OZ1JHM prototype this include a custom program that can be downlaoded along to component list and pictures

Aduino-based Amateur Radio Antenna Rotator Controller that can emulate the Yaesu GS-232A or GS-232B interface by K3NG

Build a Arduino simple signal generator with an arduino board and some resistor to work as a 8bit DAC

AX.25 Packet Modem homebrew project on Arduino

Make and automatic antenna tuner based on Arduino and using economic card. This ATU Project can be installed outdoors and controlled remotely by an rs485 link

A stepper switch controller made with arduino by N3OX

Available worldwide can be used as Arduino Shield or plug it in to you PC , or with a bluetooth adapter connect to Android. With a highly optimized software, KAI200 brings you: a. Antenna analyzer form 1 up to 200 Mhz; b. WSPR transmiter (set up by serial terminal); c. Square Wave Signal generator KAI200 is all you need for your radio whatever it is Yaesu, Icom, Kenwood or Drake and DIY projects.

A WSPR beacon project based on Arduino nano (atmega328P) based microcontroller

An home made VNA made with Arduino Nano. This project features an LCD display 4x20 works from 1 MHz to 60MHz, can use bluetooth connection with Blue VNA android app.

Two easy to build microcontroller projects for machine recognition of hand-sent morse code

Web site and blog that reviews equipment, goes over safety, and display projects being built. Includes Yaesu FT-891 and Ameritron RCS-10 Review, a 555 Morse Code Practice Oscillator, and and arduino based Morse Code Practice Oscillator

A simple DIY project for a remote cw key connected to your Flex Rig (actually it can be any other rig). On the remote side it uses and Arduino Uno board and a cheap HanRun Enc28J60 ethernet shield. On the local side it uses a key (better a keyer) connected to a serial port of your pc

Arduino Flex Controller can be used with the new Flex 6000 Signature rigs. It is a DIY project and in these pages you will find all the informations you need to build and program your own. It is a perfect companion when used next to the official SmartSDR program but it can be used in stand-alone mode, without a PC.

This page provides a detailed guide on how to receive WWVB 60 KHz time signals using the Everset ES100 module with an Arduino Due microcontroller. It explains the background of time standards and the significance of WWV radio stations in maintaining these standards. The content is useful for ham radio operators interested in time synchronization, scientific research, navigation, and radio communications. The article is written by Keith Greiner, who shares his project inspired by his passion for the subject. For more projects by the author, visit the provided links.

This blog post from KA7OEI covers the author's initial exploration into the world of Arduino, a popular open-source electronics platform. The post likely discusses the author's experiences, challenges, and successes with Arduino projects, particularly in relation to amateur radio or other technical hobbies. It may provide insights, tips, or inspiration for hams interested in incorporating Arduino into their own projects. The content is likely informative, personal, and geared towards amateur radio operators or electronics enthusiasts.

This is a basic Arduino project for decoding Morse code. This is an Arduino program that decodes Morse code from an I/O pin and display in to an LCD screen
