Good point, Artisan, there are some fine people posting at Hobby who tend to get upstaged by the brash band.
Looking back at Post # 33 Tim in Bovey said: “Distance above ground to work with the Potomac is either 7 or 30 feet. I used 7 because 30 is far too much work! Accuracy is better at 30 feet. I can’t remember off hand, I believe it’s 12% at 30 feet, 18% at 7 feet.”
Those are the standards used by Tim for testing the FM transmitters, and he explained that certifying labs use those same distances.
What I don’t recall reading is an explanation of why those particular distances are chosen… 30″ would be more convenient, being the average height of a table… so why either 7′ or 30′?
