Introduction: The Open-Source Concept
The TEN-TEC Patriot model 507 is designed
with the purpose of providing Ham Radio
operators a platform for developing and writing
code using the open-source Arduino
programming environment. It is a factory built
QRP radio with a ChipKit™ Uno32™ Arduino
compatible processing unit that holds the
operating program. The radio is provided with
programming for basic operating functions that
allow it to be used immediately as a basic QRP
transceiver. Additional operating functions can
be programmed by the user, either by writing the
code or copying/adapting code developed by
members of a growing number of Arduino
special interest groups. It is this sharing of
programming routines and ideas for
functionality that is the heart of the Arduino
open-source concept.
1.1 Unpacking Your Patriot 507
Examine the unit for signs of shipping damage.
Should any damage be apparent, notify the
delivering carrier immediately, stating the full
extent of the damage. Save all cartons and
packing material to document the damage.
Liability for any shipping damage rests with the
shipping carrier.
Note that there no accessories are included with
the Patriot 507. The assembled radio is the only
item of hardware. All power, antenna, keying
and programming connectors are standard types.
No specialized cables or adapters are required.
This manual and any purchase-related
paperwork are the only other items packed with
the unit.
1.2 About this Manual
This Operator’s Manual includes a complete
description of the features and functions of the
Patriot 507. The latest version of this manual is
also available at www.tentec.com. Also
available online are additional technical
resources, including schematic diagrams and a
list of resources to help users get started with
Arduino programming.
1.3 Power, Antenna, Keying and Audio
Connectors
The DC power connector is a 2.1 mm coaxial
power connector with the center pin positive (+).
A user-provided power source of 10-15 VDC is
required. Capable of providing at least 1.5 amps
of current.
The antenna connector is a female BNC
connector. The impedance is 50 ohms.
The microphone jack connector accepts a
microphone wired for Ten-Tec radios. And also
serves as the Connector for other forms of
modulation i.e. digital.
The Key/Paddle connector is a 1/8” stereo jack.
As provided by the factory, only a key or
external keyer may be used, with connection to
the tip and sleeve. Tip, ring and sleeve are
available if the user chooses to include a CW
keyer when programming the ChipKit Uno32.
The Speaker/Headphone connector is a 1/8”
stereo jack. The factory setting is for
headphones, and either monaural or stereo types
may be used. If a speaker is preferred, an
internal jumper may be moved, which will drive
a speaker connected between ring and sleeve.
See Sections 3 and 4 for additional details.
