Title : A LimeSDR Mini Based Es’Hail-2 DATV Ground Station
Uplink
Content : Daniel Estevez has posted on the LimeSDR Mini
CrowdSupply blog about his ground-station build for the Es'Hail-2
satellite . Es'Hail-2 is the first geostationary satellite with
amateur radio transponders on board. The LimeSDR Mini is a $159
RX/TX capable SDR with 10 MHz to 3.5 GHz frequency range.
Title : The HAARP Project Explained Simply
Content : Over on YouTube Curious Droid has uploaded an
interesting video that attempts to explain the purpose of the
HAARP transmitter project. The High Frequency Active Auroral
Research Program (HAARP) is an ionospheric research program based
in Alaska. It consists of a high power transmitter and antenna
array which is used to excite a portion of the atmosphere in order
to study the ionosphere and investigate methods of affecting radio
communications. Recently HAARP was also used in an art project called
" Ghosts in the Air Glow " which saw HAARP used to transmit several
audio art pieces.
Title : Reverse Engineering and Controlling a Wireless Doorbell
with an RTL-SDR and Arduino
Content : Thank you to Shreyas Ubale for submitting his blog post
about reverse engineering a wireless doorbell, and then performing
a replay attack . Shreyas had purchased a wireless doorbell set
containing one button transmitter and two bell receivers. However,
his situation required two transmitters, one for visitors at the
door, and one to be used by family within his house.
Title : ExtIO_RTLSDR# – Modified ExtIO for SDRUno/HDSDR with
Direct Sampling Mode
Content : Fixed RTL-SDR EXTIO for SDRUno.
Title : SignalsEverywhere Podcast: Satcom Piracy Interview
Content : Corrosive from the SignalsEverywhere YouTube
channel has released a new episode of his podcast. In this episode
Corrosive interviews an anonymous informant who has an interesting
story about his involvement with the UHF Military SATCOM pirate radio
scene in Brazil. Corrosive also explains a bit further about what
SATCOM is and why it's so susceptible to piracy. He also notes that
piracy on Inmarsat L-band frequencies is also becoming more common.
Title : Tracking and Recovering A NWS Weather Balloon &
Radiosonde with an RTL-SDR
Content : Over on YouTube OLHZN High Altitude Balloons has
posted a very entertaining video showing how to use an RTL-SDR
and small grid dish antenna to track and recover a fallen weather
balloon and its radiosonde. OLHZN writes:
Title : SignalsEverywhere: Common Modulations Tutorial Video
Content : This week on the SignalsEverywhere YouTube channel,
host Corrosive gives us a tutorial on common modulations that you'll
see on your software defined radio. His tutorial covers Amplitude
Modulation (AM), Frequency Modulation (FM), Single Side Band (SSB)
and Conintuous Wave (CW) modulations. In the video he shows what
they look like and how to select the correct mode and bandwidth
settings in SDR#. Corrosive uses an Airspy in the video, but the
same concepts are valid for any SDR, like the RTL-SDR.
Title : An RTL-SDR and Pi 3 Based Ground Station for Simulated
CubeSats
Content : CubeSats are small and light satellites that can these
days be built and launched into orbit by almost anyone with a small
budget of roughly $40,000. They are a great way for schools and
other organizations to get into a space based technology project. A
"simulated" CubeSat is one that is not designed to be really launched
into space, and is made from low cost hardware. The idea is that
simulated CubeSats can be used as tools to help demystify the inner
workings of satellites to the public and help CubeSat builders get
experience and competence before building the real thing.
