|IRLP - Keeping the Radio in Amateur Radio
I set out to design a better way to use the same technology to perform the same task, while improving usability, user control, and sound quality. My first breakthrough was to replace the existing operating system, Windows, with a more stable and versatile language. I chose Linux, an open source form of the operating system UNIX designed by Linus Torvalds, because of its superior networking characteristics, its reliability, and its ease of programming.
I designed my own interface board to interface the radio to the computer. This allowed a large amount of delay to be removed from the system because two VOX circuits were no longer being used . I also wrote my own custom control software, and modified an existing voice-over-IP software package to accommodate the project.
The final product was a combination of hardware and software that created a nearly seamless radio link between two remote sites on the internet. The product works so well that many people can not believe that they are talking through a link at all!
