PREFACE
Thank you for buying the RIGblaster duo . Whether you are upgrading from another RIGblaster ,
another sound card interface, or this is your first interface, we think you will be pleased with the
capabilities of the duo. After building over 25,000 RIGblaster sound card interfaces we are pleased to
introduce an interface designed especially for a station with two radios that makes a station neater,
simpler, more efficient and easier to operate. It features a receive monitor switching, mixing and
amplification system patterned after an aircraft audio panel. We hope that you find it makes your station
better in every way.
Integrating the audio and switching of a station with two radios is complex but we have made every
effort to make the RIGblaster duo as easy to operate and toinstall as possible. Front panel controls
are laid out to be intuitive and ergonomically correct. You should be able to understand the operation
simply by looking at the controls. You only need to become accustomed to having a single mic, a
single pair of headphones and using a master volume control.
Front panel status indicators show at a glance, signal routing, audio source and status of PTT, CW and
FSK control and keying. In addition to seeing the position of the transmit-select switch, optional
external LED indicators are available to be located at each radio to make it obvious which radio is ready
for transmit.
In many ways the installation is actually simpler than other model RIGblasters except that each radio
has its own connections. The installation will be well worth the effort as you will have your station
totally integrated.
This manual is written with a step-by-step approach explaining how to connect and use the primary
features first, and then later the advanced options. You may not want nor need some of the advanced
options so you may ignore them if you wish. Of course if you understand and know what you want to
do, feel free to continue into the manual as we explain how to add more and more functions and
features. It depends on your desire to experiment; in the spirit of Amateur Radio; that’s what it is all
about!
The RIGblaster duo was conceived as a platform to support all Amateur Radio sound card software,
keying and rig control software, even software that has not yet been written.

PLEASE NOTE:
In this manual we will refer to the sound device on a computer as “Sound Card”. We understand many
computer sound devices are integrated onto the motherboard of the computer, or can be external. We
will stick to the more familiar wording “Sound Card”. Note that RIGblasters do not have built in
sound. If they did it would mean that you would have to disable the internal sound system in your
computer to use most Amateur Radio sound card software, because most programs cannot select the
computer audio device. All RIGblasters leave your computer sound fully functional just as it was
before, yet you have full capabilities will all Amateur Radio sound card programs and operating modes.
The words “Radio”, “Transceiver” and “Rig” as used within this document are synonymous.
Throughout this manual any reference to using a computer is worded for a Windows® computer. You
may have to interpret the wording to suit a Mac OS® or Linux® computer to fully understand references
to using a computer.
AN IMPORTANT NOTE ABOUT STATION GROUNDING:
Interconnected electronic equipment, such as an Amateur Radio station, is a system. Interconnected signal
cables must only carry the signals (RF, audio, power or control) they are meant to. They should never be
allowed to be power ground interconnects!
Your station making up this system must be grounded properly at a single point! All desktop computers,
monitors and printers have AC power cord ground connections. The computer AC ground must be
connected to the station ground at a single point. If you radio grounds are not connected to the same physical
location, and AC ground potential; that ground current will be superimposed on the desired signal.
Simply connect the radio grounds, station grounds and AC grounds together at the same physical point. Do
not daisy chain the grounds from one unit to another! This will not only make all the equipment work
properly as a system but it will be much less likely to have damage from a nearby lightning strike.

CHOOSE A MOUNTING LOCATION
The supplied microphone cables are 3 feet long and the computer cables are 6 feet long. Choose a
location that allows these cables to reach your radios and your computer. You may extend the computer
cables within reason or you may purchase optional 6 foot microphone cables. It makes sense to have
your computer at your operating position with the radios. Do not attempt to run the
RIGblaster duo
with a computer across the room, especially if it is on a different house wiring circuit than your ham
station. Put your radios and computer together so everything is at your fingertips for maximum
operating convenience. The
RIGblaster duo is intended to help make your station convenient to use.
If possible set up your station so you have access to the back panels of all the equipment.
Note: the top cover can be removed without disconnecting the cables, for easy access to the internal
jumpers. Therefore, if possible, mount the RIGblaster duo where you can remove the cover.
If you will be using a hand microphone with a coiled cord, consider the tug on the cord. The
RIGblaster duo is fairly heavy but could be pulled around by a coiled mic cord. Use the supplied
double sided foam stick-on pads as an easy way to secure it.
Locate the RIGblaster duo at least 18 inches from anything that has a strong magnetic field, such as
transformer type power supplies, amplifiers, CRT type monitors or rotor control boxes. Do not put the
RIGblaster duo in strong RF fields.
The RIGblaster duo requires little ventilation and can be put in any cool location that does not block
the ventilation for another piece of equipment that does require ventilation.
INSTALLATION PLANNING
This instruction manual is written, and the RIGblaster duo is designed, to accommodate any operator
no matter what equipment he or she may have, or what type of operating they would like to do. Beyond
the basic function of the RIGblaster duo as a station integration console there are many other options
from which to choose. This would depend on how you wish your station to work and what type of
operating you would like to do.
Advanced options are towards the back of this manual and the basic installation and operation is first.
Continue through this manual, in order, front to back to make setting up the RIGblaster duo an easy
step by step process. Start with the primary functions and later explore the advanced options.
We will proceed in order. After you have your station set up to operate more conveniently than ever
before we will discuss operation with Amateur Radio sound card software. Next we will cover
advanced options, including; CAT/CI-V rig control, CW, FSK keying and special audio routing.
Only attempt a full configuration of the RIGblaster duo from the start if you have a complete
understanding of exactly what you wish to do and how you would like your station to operate. You also
need an understanding of how these advanced options function, how they are used, their intended use
and why you would want them; before attempting to configure everything at once.
