Title : Electrosense+: Global Network of RTL-SDR Sensors with
Decoding of FM/AM ADS-B AIS LTE ACARS
Content : Back in late 2019 we posted about the Electrosense
network which is an open source project aiming to deploy radio
spectrum sensors worldwide. The idea is to help analyze and
understand radio spectrum usage across the globe. Each sensor
consists of an RTL-SDR, Raspberry Pi and an optional downconverter
to receive the higher bands.
Title : Tech Minds: Eavesdropping on Video Monitors with TempestSDR
Content : Over on his latest video Tech Minds' explores the
use of TempestSDR to eavesdrop on video monitors with his Airspy
Mini. TempestSDR is a program that we've posted about several
times in the past. With an RTL-SDR or other compatible SDR like
a HackRF it allows you to reconstruct an image from a computer
monitor or TV just from the radio waves unintentionally emitted by
the screen or cable. SDRs with larger bandwidths like the HackRF or
Airspy are better at reconstructing the image as they can collect
more information.
Title : Imaging the Milky Way in Neutral Hydrogen with an RTL-SDR
Part 2
Content : Last month we shared information about Job Geheniau's
success with using an RTL-SDR dongle to image our galaxy in neutral
Hydrogen. Our galaxy is full of neutral Hydrogen, and lots of
neutral Hydrogen together results in a detectable radio peak at
1.42 GHz. This peak is called the Hydrogen line. By scanning the
galaxy at the Hydrogen line frequency with a 1.5 meter dish on a
motorized mount, an RTL-SDR, and a few filters and LNAs, Job is
able to create a radio image of our galaxy.
Title : An Introduction to Radio Trunking Systems with a Focus on
P25 and SDR Trunk
Content : Thank you to Carl Makin (VK1KCM) for submitting a video
that he produced for his local ham radio club in Australia. In the
video Carl first gives an overview on radio trunking systems and
explains why they are used to improve spectrum efficiency.
Title : A Simple Guide to Setting up a DIY NOAA Weather Satellite
Ground Station
Content : A few weeks ago we posted about Sophie Dyer and
Sasha Engelmann's work in creating an artistic performance based
on weather satellite reception with SDRs. More recently they
have uploaded their own tutorial showing how they receive NOAA
APT weather satellite images with an SDR, turnstile antenna and
computer. Sasha and Sophie note that they are attempting to create
visually rich guides that don't assume any prior knowledge of radio,
science or engineering.
Title : Guest Post: So you’ve bought an RTL-SDR, now what?
Content : Thank you to Merlin from the SignalsEverywhere discord
channel for writing this guest post.
Title : Step-by-step Guide to Creating a GNU Radio Based QO-100
SSB Receiver
Content : Thank you to M Khanfar for submitting his video that
shows a step-by-step tutorial on building your own SSB receiver in
Windows GNU Radio for QO-100 satellite reception. His tutorial
includes adding several tuning sliders in the GNU Radio GUI as
well.
Title : Frugal Radio: 2020 SDR Guide Ep 1 – The Incredible
World of Software Defined Radio (RTL-SDR, Airspy, SDRPlay etc.)
Content : Frugal Radio has begun his YouTube channel a few weeks
ago, and we've already posted about his YouLoop and SDR-Kits
L-band patch antenna reviews as well as his results with the
YouLoop on LF & VLF .
