Home-brew Arduino-based QRP CW transceiver

 For the non-amateur radio enthusiasts the title translates to an Arduino-based low power morse-code transceiver. And one excellent example has been demonstrated by M0XPD in the United Kindom who made such a transceiver over a series of Arduino shields. As you can see from the stack in the image below the transmit and receiver modules are each relegated to a shield, and the Arduino-compatible board controls the AD9850 direct digital synthesis IC mounted on another shield to generate the radio frequency signals to transmit. It's an   excellent demonstration of synergy between Arduino and the world of amateur radio. 

For more information and other interesting projects, check out M0XPD's website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

When creating your own customised Arduino shields such as the QRP system above, you'll need a protoshield or three to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
