What I like on the radio is the social part. The whole thing is about meeting different colleagues worldwide, exchanging ideas, getting ready, sharing experience, and the driving attitude to "make it better". Portable expeditions are always of my interest. They prove the quality of the colleagues. They prove the hardware as well. It's like scouting. Slowcoach, talkers, drop hammers, Hillbilly rednecks, and overinflated hot air baloons can stay at home. Based on present experience, the published ideas are copied and exploited within few months. A company from Ohio took the copying further into production, Silberwood from San Jose as well. :)) Therefore, the article content is limited.
