My DS14 showed up today. Very impressive! I have a question though. The thing is beeping when I have the RX turned on. Over and over. Everything is fully charged, but I just cannot find what the beep is for? Also, it said something about an unregistered RX. Do you have to register your RX's , and if so, where is this done? Certainly a lot to learn with this radio. I tried to buy some upgrades as well, and it would not take paypal. Now my account is not showing a registered radio, but when I input all of the SS numbers it says that radio is already registered. Maybe some goofy stuff going on with the website?
