WHAT IS D-STAR
• Digital – Smart Technology for Amateur Radio
• ICOM’s 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)

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 person’s call sign
• D-STAR Replace Analog FM???


Akin to AM to SSB on HF in the 50’s and 60’s
Not to worry – D-STAR and Analog will co-exist for a long
time

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)

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
15 – 20 repeaters in Southern California

D-ECHO
Authored By: Robin Cutshaw, AA4RC
• The repeater will record your transmission and play it back
upon un-keying.
• The application is invoked by entering repeater call-sign and ‘E’
into the UrCall field (e.g. KF6BQK E).

Getting Started
Local Repeater Usage
• No Squelch Tails Or Courtesy Beeps From Repeaters

But You Do Get A Status Read Back!


Ur* Or Ur? Usually Means You Did Go Through
RPT* Or RPT? Usually Means You Did Not Go Through
Local Repeater RPT* -Try Again
Gateway Ops RPT*
Check Your Routing Calls RPT1 & RPT2 Or Local Gateway Could Be Down
Remote Repeater Could Be Busy
• Short Transmission From The Repeater

About 1 Second After Unkeying
• Be Conscious Of How Close To The “Cliff” you Or Other
User May Be

RADIO INITIAL SETUP - DV
• Turn on Radio
• Set Frequency as for Analog FM (Mt Woodson 446.980
MHz)

Set offset (±0.600 MHz for 2M; ±5MHz for 440 )
• Decide on the Communication You Want to Accomplish

To whom you want to talk

Defined by “RPT1” and “RPT2”
• Enter / Program Call Signs into the Radio

Push Buttons, Turn Knobs to Alpha Numeric Entry Areas
1. “MyCall” Always the Radio Owner’s Call Sign (e.g. Cecil uses WD6FZA)
2. “UrCall” Always the Station Being Called (CQCQCQ, Repeater, or Individual)
3. “RPT1” Call sign (& port) of the originating (input) repeater
(Local Repeater e.g for Woodson use KI6KQU^A, B, or C)
4. “RPT2” Call sign & designator of the gateway or cross band port
 Call Routing (Local Repeater e.g for Mt. Woodson use KI6KQU^A, B, C, or G)

Gateway Essentials
• Registration Required For Gateway Operation



Get With Your Local Administrator To Get Registered
Registering More Than Once Can Mess UP Gateway Data Base
Similar to IRLP Except

D-STAR Calls Are Automatically Routed
• No Registration Required For Local Use
• Conversations Are NOT Private

Both Ends Hear All
• User Linking / Routing, Not Site Linking
• User Determines The Route His Transmission Takes
• Program Your Radio Ahead Of Time For Mobile

THE CUTTING EDGE?
• Not the only digital game in town, but it works
out of the box
• Excellent performance on 440
• ISDN rate internet access via ID-1
• Transparent call routing throughout the D-Star
Network
• Significant experimentation and innovation is
occurring (e.g., home brew radios, openstar.org)
