Hi Assaf:Thanks. That's right. Those sticks tend to have caps don't they. I hadn't considered that. Hmmmm. Perhaps it isn't a solution after all. But in answer to your question, I believe the amateur radio apps being demonstrated are audio rather than video - CQ 100 and HamsPhere. We'll also have to test the stick ahead of time to make sure it can communicate from inside the restaurant.
