Make an Arduino-based amateur radio antenna tuner

Once again Jean-Jacques De Rey, ON7EQ brings us another excellent project that finds synergy between the Arduino development platform and the world of amateur radio. In this example he has designed and build an antenna tuner for his 20/40m end-fed half-wave antenna, that can be interfaced for control by and used with his Icom IC7000 transceiver.

The Arduino is used to interpret commands from the transceiver - including SWR data from the inbuilt meter on the Icom,  and uses a rotational servo to adjust the variable capacitor in the tuner. Then the tuner works through the entire range of the capacitor, noting the SWR levels and then returns to the best point in the adjustment.

Another great example of home-brew, and complete details can be found on the tuner page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're interested in more advanced Arduino projects and usage - get yourself a copy of "Practical Arduino" by Jonathan Oxer and Hugh Blemings: 

Create your own Arduino-based designs, gain an in-depth knowledge of the architecture of Arduino, and learn the easy-to-use Arduino language all in the context of practical projects that you can build yourself at home. Get hands-on experience using a variety of projects and recipes for everything from home automation to test equipment. For more information and to order, click here
