No, you shouldn't be worried. I'm not sure if you're putting us on or not, OM, but unless you've done something else, the van is not after you. Here are the facts: 1. In the U.S. it is only forbidden to work hams whose countries do not allow contacts with us. There have been very few such nations over the years. 2. Amateur radio in Cuba has a long history. You can work Cuban stations any day of the week and have a nice ragchew. Many are club stations, but many are just normal hams. 3. I would guess the confusion on your part is due to a busted call.
