4 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 4 Types of Hardware Purpose Built Radios TNC Based Systems Sound Card Based Systems

5 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 5 Purpose Built Radios Purpose built radios are designed specifically to support ARPS functions in a single package. Just add a GPS receiver and go. –Kenwood TM-D700A –Kenwood TH-D7A –Alinco DR-135T MKII with EJ-41U TNC

6 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 6 Kenwood TM-D700A Coolest APRS radio on the market Dual band 114/440 MHz 50/35 Watts Decent 1200/9600 bps TNC Built-in Digipeater One screen text monitoring PC programmable Just add a GPS and go

7 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 7 Kenwood TH-D7A(G) Nice HT with APRS features Dual band 114/440 MHz 5 Watts Basic TNC One screen text monitoring PC programmable Just add a GPS and go

8 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 8 Alinco DR-135T/EJ-41U Basic 2 M Radio with optional TNC Allows direct input from GPS Requires PC to setup No APRS display on radio Basic 1200/9600 bps TNC

10 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 10 TNC Based Systems Roughly divided into two categories – Beaconing Only and Transmit/Receive The major elements include: –2 M Radio (Just about anything will work) –Terminal Node Controller (TNC) (Again just about anyone will work) –Computer to set up system and possibly run APRS application. –GPS Receiver if mobile

11 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 11 Beaconing Only Systems This is one of the lowest cost and easiest ways to begin to experiment with APRS. This configuration provides you with a system that periodically transmits your position from a GPS receiver. It does not provide you with the ability to receive and decode packets. –Byonics TinyTrak3 –Tigertronics TigerTrak TM-1 –TAPR PIC-Encoder

12 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 12 Typical Characteristics of Beaconing Only Systems Low Cost Transmits only position information Some systems are available as kits Easy to setup, once you figure out how Simple hardware configuration Normally allows for stand alone operation

13 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 13 Basic Interconnection Diagram Beaconing Systems GPS Radio NEMA Data TNC PTT XMT RCV

14 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 14 Transmit/Receive Systems These are a step up from the basic Beaconing system. Setup is very dependent on the actual TNC used. A computer and application software may be required, depending on the software version in the TNC. Digipeating is possible with most TNCs.

15 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 15 Typical Characteristics of Transmit/Receive Systems A generic 2 M radio is required. TNC may support GPS receiver directly –Kantronics KAM, KAM+ v KPC-3, KPC-3+, KPC- 9612, KPC-9612+,v6.0 or higher –Timewave AEA PK-96 –There may be others

17 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 17 Sound Card Based Systems No TNC is required Uses PC sound card to transmit and receive signals from radio Simple interface circuitry (The same as PSK31) Requires a modest computer to operate Probably the hardest to get running and keep running

18 APRS is a registered trademark Bob Bruninga, WB4APR Copyright © 2003 – Anthony Campbell W5ADC All Rights Reserved 18 Basic Interconnection Diagram Sound Card Based Systems GPS Radio NEMA Data In/Out Computer PTT XMT RCV A Weather Station could be used in place of the GPS with most applications
