Aviation Radio Shield for Arduino, monitoring 8 or more frequencies at one time!

We need your feedback on James' design for a software controlled radio, designed for Arduino. The radio allows monitoring 8 or more aviation frequencies. The board is very small and is planned for a Kickstarter launch soon! Send an email to [e-mail] with your questions and feedback and we'll get you registered for first notice on the kickstarter (along with the early bird discount). You'll also get a brief whitepaper on the design of the radio.
