11 The PAPA System www.papasys.org

2 CONTENTS About D-STAR Key Benefits Why D-STAR D-STAR Benefits D-STAR Radios Stand alone system operation Gateway (Linked) system operation RF configuration of repeaters Resources Conclusion www.papasys.org

33 WHAT IS D-STAR Digital Smart Technology for Amateur Radio ICOMs implementation of JARL open standard for UHF/VHF digital voice and data communications 2 Meter, 440 MHz and 1.2 GHz Consists of radios, repeaters, and (optional) Gateway hardware and software Gaussian Minimum Shift Keying (GMSK) with forward error correction New Modulation Scheme RF aspects remain unchanged (RF is RF) www.papasys.org

WHY D-STAR Why Not D-STAR? Something in it for everyone Gateway and PC for Data Commx, Programmer, and Networking Interests RF for the Antenna and RF System interests Rag Chewing on Local and Gateway Repeaters Amateur Radio allows experimentation An experiment that seems to be working More Elegant and targeted form of networking than IRLP or EchoLink Must know users QTH and node number at that QTH D-STAR only requires knowledge of persons call sign D-STAR Replace Analog FM??? Akin to AM to SSB on HF in the 50s and 60s Not to worry D-STAR and Analog will co-exist for a long time 4 www.papasys.org

55 KEY BENEFITS Digital Quality Voice Communication Simplex Or Via Repeater Coverage On 440 Equal To Or Better Than Analog 10% To 15% More Range Try It And Report Back Audio Quality Is Consistent Nationwide Routed Call Sign Calling Via Gateway No Need To Know QTH Of Target Key-up Networked D-STAR Machine And The World Knows Your QTH Data Transmission Low-speed Data On UHF and VHF Wideband Service Is Available On 1.2 Ghz With Up To 128K Baud Rates Wireless Internet Access Via Router Available (1.2 GHz) Part 97 Presumably Applies To Content www.papasys.org

66 Additional Benefits Extensive support via forums and user groups Lower RF bandwidth requirements (6.25 KHz vs.16 KHz) Digital messaging in Digital Voice mode i.e., works on 2M, 440 or 1.2 GHz) Location services (e.g., D-PRS/APRS) IP compatible, OPEN JARL standard Probably between 500 + repeaters on the air (Internationally) Approximately 500 Gateways Approximately 20000 (???) Registered users Gateway users each day estimated 600 to 700 + www.dstarusers.org www.dstarusers.org 15 20 repeaters in Southern California Multicast Capability www.papasys.org

D-STAR Radio Capabilities D-STAR Radios Modes Radios work in both digital and analog modes and dual banders are available AM, FM, FM-N, and Digital Voice (DV) DV Dongle Station Identification is Automatic in DV Built Into Each Digital Signal Sent Meets all FCC Identification Requirements Can Send Simultaneously (and Display on The Radio) Your Name, GPS Position, and Text Message in the same Data Stream at 2400 Baud At 2X Packet Speed 11 www.papasys.org

DV Dongle www.papasys.org 12 AMBE Dongle Provides AMBE 2020 interface between a radio and computer through USB port. Computer can monitor and process baseband packet stream Many more uses
