What Use Is An F-call?

What use is an F-call? Recently I heard an f-call ask on-air about the performance of their HF antenna. It reminded me that in order for any learning to occur, there needs to be two elements that come together. While it's simple to ask questions among your friends, it takes a leap of faith to ask a stranger. So, one of the elements you need is a Leap of Faith, "I have a problem and I wonder if anyone might be able to help." For this leap of faith to pay off, you also need to gain access to the knowledge required to solve your problem. It can come in many guises, from "read the manual", through "I have done that and I solved it like this." to "Let me come over and give you a hand." The second element that is needed is Generosity. The interesting part for me is how the discussion opens up many possibilities when experienced people enter the conversation. It's one thing to acknowledge the original Leap but two inexperienced people talking to each other about a problem
