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

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

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.
