Purpose Built Radios
• Purpose built radios are designed specifically to
support ARPS functions in a single package. Just
add a GPS receiver and go.

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

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.

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

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 TNC’s.

Typical Characteristics of
Transmit/Receive Systems
• A generic 2 M radio is required.
• TNC may support GPS
receiver directly
– Kantronics KAM, KAM+ v8.2
-- KPC-3, KPC-3+, KPC9612, KPC-9612+,v6.0 or
higher
– Timewave AEA PK-96
– There may be others

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
