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

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
