Danny Knaggs, 2E0DPK is developing a new free Ham protocol. DDP, Danny's Digital Packet, is a new Alternative Protocol for Packet Radio. It works with FLDigi or D-STAR DV. What is different is that the packets are sent and recieved in plain text on the waterfall. This is a very interesting development that will work with several operating systems. This is still Beta, so may the testing begin.
