Thank you for inviting comments on the Wassenaar Arrangement Plenary
Agreements Implementation for Intrusion and Surveillance Items. As a member of
the information security community, I am concerned about the effects of the
proposed implementation on my industry.
My greatest concern is clarity of the proposed rule. If you must provide an
answer to a frequently asked question about what a rule means, it may be
because the rule was not written clearly. I was particularly troubled by the
publication of the FAQ regarding the proposed rule, partly because it indicated
a lack of clarity in the rule but also because the answers didn't seem much
clearer. Had the answers been clear, I would still be concerned that the text
of the rule would not be interpreted in the future in the same manner as your
present interpretation. The text matters, and it is overbroad and unclear even
to well informed members of the information security community.
Unfortunately, computer security is an unsolved problem. The people who are
working to improve the state of the art of computer security are diverse
members of a global community of researchers. The proposed rule directly
prevents the sharing of information among those researchers, and it will have a
negative impact on the security of computing systems and software for the
Software is a form of information, and control of the flow of information is
very different from control of the transport of physical goods. I urge you to
remove software from the scope of the Wassenaar Arrangement at the annual
meeting of Wassenaar Arrangement members in December 2015.
Black Hat Student Pass
If you are a full-time university student and would like a free ticket to
this summer's Black Hat
Briefings, send an email to firstname.lastname@example.org today. We have
two tickets to give away, and we would like to give them to students who share
our interests. You must meet Black Hat's criteria,
and you will be responsible for your own travel and lodging.
We'll be busy at Black Hat USA this year. I'm teaching two
sessions of my Software Defined Radio class, and I will be giving a talk
at the Briefings about the NSA Playset. Additionally, Taylor and I will show off
a new project called YARD Stick One at the Black
HackRF One at 1 MHz
We've decided to advertise the fact that HackRF One operates all the way
down to 1 MHz, not just to 10 MHz. This isn't a change to the hardware design;
it is simply an acknowledgment that the hardware has always worked at such low
frequencies and that we support operation down to 1 MHz.
In fact, HackRF One
can even function below 1 MHz, but the performance drops considerably as
the frequency decreases. The curve is reasonably flat down to about 1 MHz, so
we consider that to be the lower limit for most uses.
Now that we've seen consistent low frequency performance across multiple
manufacturing runs, we're comfortable changing the official specification:
HackRF One operates from 1 MHz to 6 GHz. Try attaching a long wire antenna to
listen to shortwave radio!
Although HackRF One has reasonable performance down to 1 MHz, it performs
better at higher frequencies. To get the best possible performance down to 1
MHz and lower, I recommend using an external upconverter/downconverter such as
the excellent Ham It
Up, open source hardware designed by
Open House Invitation
For the first time ever, Dominic, Taylor, and I will all be in the same
place at the same time in June. We decided we should celebrate, and you are
Please join us at our recently expanded lab in Evergreen, Colorado on 11
June 2015 from 17:00 to 19:00. You can see the lab, talk to us about our
projects, check out our latest prototypes, and even learn to solder!

Free Stuff, February 2015
Great Scott Gadgets is pleased to announce the recipients of our inaugural
Free Stuff give-away. This being our first give-away,
we got a little overexcited and ended up giving away 5 HackRF One units to
people who made requests in February! We were excited to see so much interest
in our Free Stuff program, and after much deliberation we were able to narrow
the field down to these 5 entrants. Congratulations, and we can't wait to see
what you do with your HackRF Ones!
Alex Page wrote to us representing the Interlock hackerspace in Rochester, New
York, which has recently begun hosting SDR meetups. They have been encouraging
those new to SDR as well as seasoned veterans, and they have made a space where
they can all interact. We are awarding Interlock a HackRF One unit to
encourage this sharing of knowledge. Thanks Alex, and keep up the good
JinGen Lim is a promising student and developer from Singapore. When HackRF
One was released he used it as an inspiration to build his own open source
device called CCManager. We
awarded JinGen a HackRF One unit to see what he can come up with next. Thanks
for making your ideas open source JinGen!
Rajesh Kannan is a licensed amateur radio operator and enthusiast as well as
a rather successful amateur meteorologist. Rajesh has plans to use his HackRF
One to help develop an HRPT satellite receiver with a group of students in
India. Thanks Rajesh for igniting the RF spark in the next generation!
Taavi Laadung is a graduate student at the Tallinn University of Technology in Estonia.
He is working on a nanosatellite project and plans to use the HackRF One that
we give him to help build a ground station. Thanks Taavi for including the
HackRF One in your research.
Chris Johns is a student at Spokane
Community College in Spokane, Washington, and with the help of a few other
members of their technology club Chris plans to use his HackRF One to start an
amateur digital TV station. It's an interesting proposition, and we thank you
for trying it out, Chris. Good luck!
Thanks to everyone that sent us a request. If you didn’t send us a request,
why not? It never hurts to ask. We look forward to seeing what you come up
