RE: Open Source Remote Control System (OSRC)
A radio system already exists that is more or less open source. Search out the Microstar 2000, Gordon Anderson and the Ace Micro Pro. They are all related and the Microstar is the latest revision.
The Microstar encoder is inexpensive and can be added to nearly any radio system manufactured within the last 40 years to make it a computer radio. The software is updated on a regular basis to keep the system up to date and even ahead of most any system currently manufactured.
Instead of re-inventing the wheel, why not improve or modify this system?
