Outline What is D-STAR? What is D-RATS? Goal Messaging Files and Images Positional Awareness

Outline What is D-STAR? What is D-RATS? Goal Messaging Files and Images Positional Awareness Network Connectivity Implementation

What is D-STAR? Purely digital mode Simultaneous voice and data High-speed (DD) and Low-speed

What is D-STAR? Purely digital mode Simultaneous voice and data High-speed (DD) and Low-speed (DV) Repeater and gateway infrastructure All DV radios can do ~950 bps data No modem required Just a serial port (no framing, ECC, etc) Not 8 -bit safe

What is D-RATS (Goal) All-in-one tool for D-STAR data ops Provide real uses for

What is D-RATS (Goal) All-in-one tool for D-STAR data ops Provide real uses for the slow data channel Oriented at Em. Comm No dependence on infrastructure Originally targeted for simplex All network interaction at endpoints

What is D-RATS? (Changes in 0. 3) Improved User Interface Provide more BBS-like behavior

What is D-RATS? (Changes in 0. 3) Improved User Interface Provide more BBS-like behavior (still at endpoints!) Email-client-like messaging interface FTP-client-like file transfer interface Better event capture and logging Email transport of forms (interface with Win. Link) Mapping improvements, dynamic data, speed Multiple data ports (multiple radios, networks)

What is D-RATS? (Messaging) Free-form multicast chat messages Checksum-protected No ACK/NAK from remote stations

What is D-RATS? (Messaging) Free-form multicast chat messages Checksum-protected No ACK/NAK from remote stations (yet) Structured messages Use XML to convey structure and content XSL at the endpoints for presentation Email gateway Crafted headers for reply and forward Ad-hoc setups at the end points (no infrastructure)

What is D-RATS? (Files and Images) Arbitrary file transfers with sliding window, compression, and

What is D-RATS? (Files and Images) Arbitrary file transfers with sliding window, compression, and resume “File server” for remote retrieval Integrated resize/resample of image files

What is D-RATS? (Positional Awareness) Captures and sends ICOM GPS strings Distance and direction

What is D-RATS? (Positional Awareness) Captures and sends ICOM GPS strings Distance and direction calculation Integrated map display External GPS to multiplex the port Moving stations updated in real-time Free maps!

TNC – The gateway drug to D-STAR data Use a KISS-mode TNC with D-RATS

TNC – The gateway drug to D-STAR data Use a KISS-mode TNC with D-RATS Gives you point-to-point data transfer No AX. 25 Simpler to setup Lower overhead Interface with D-STAR users through stations running both formats
