µController Arduino - HF Projects

Click to enlargeAD9850 DDS VFO by AD7C
The AD9850 is a chip that can produce a sinusoidal wave from about 1hz to 40mhz.
To control the AD9850 you’ll need some sort of micro-controller.

An Arduino Controlled GPS Corrected VFO by W3PM/GM4YRE
A VFO that provides 1 to 112.5 MHz signals on two independent outputs. Use it as a stand alone unit or with a GPS receiver to improve frequency accuracy. UTC and six digit grid square locations are also displayed in the GPS Mode.

Click to enlargeArduino DDS Shield by MŘXPD
This being my first ever experience of a Wotduino shield (much less an Arduino shield) I was interested to get some pukka "stackable headers" to allow the new shield to ride shotgun atop the Wotduino...

Click to enlargeArduino QRP Transceiver by MŘXPD
Meet my new rig - a QRP CW Transceiver for the lower HF bands, built around the Arduino "open-source electronics prototyping platform".

A Simple Arduinodriven Direct Digital Synthesiser Project by G8HKS
Our Technical Editor gets involved in creating a simple HF DDS local oscillator project. Don't worry; he assures us it's not that difficult!
