Enthusiast Todd Harrison was tasked with replacing the frequency display for a Kenwood TS-520S amateur radio transceiver, and is well on the way to creating an Arduino-based solution which not only works, but is cheaper than the replacement Kenwood unit. Todd's first post is the start of a long journey that reads as an excellent tutorial on all the subjects involved - and well worth a look. He starts off with the following video:
Many amateur radio enthusiasts from around the world have found uses for an Arduino-compatible board in their arsenal. Examples include the Morse code CQ-caller by Peter Parker, Ernest Neijenhuis' motorised antenna tuner and WB7FHC's Morse code to text converter.
If Arduino is new to you, but you're not sure how to start - then the best way to learn is with out new Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
