Title : rtl-sdr.com
Title : Automatically Photographing Passing Aircraft with an RTL-SDR,
Pi 3, and IoT Software
Content : Arun Venkataswamy has recently completed a write up about
his system which automatically captures images of passing aircraft
. It works by using a Raspberry Pi and RTL-SDR to listen to ADS-B
broadcasts from aircraft. These broadcasts contain the live current
location and altitude of all aircraft in his area. When a landing
aircraft is detected to be passing near his house, the Raspberry
Pi sends a signal to another Raspberry Pi connected to a camera on
his balcony, and that snaps a photo of the passing aircraft.
Title : Mike Tests out L-Band STD-C and AERO with a Low Cost Modified
GPS Antenna
Content : SDR-Kits.net have begun selling low cost GPS antennas
that are modified to receive the Inmarsat satellite frequencies
between 1535 MHz to 1550 MHz . They also have a version for Iridium
satellites that receives 1610 MHz to 1630 MHz . The antennas are
powered by a 3-5V bias tee, so they should work fine with SDRplay,
Airspy and RTL-SDR Blog V3 units.
Title : Podcasts: GNU Radio with Ben Hilburn + New Signals and
Bits Episodes
Content : The Scanner School Podcast has recently released a new
episode featuring an interview with Ben Hilburn, President of the
GNU Radio project . If you want to understand what GNU Radio is,
and what role it plays in the SDR/radio world, then this is a good
listen.
Title : PEPYSCOPE: A Simple Panadapter for HF Radios using RTL-SDR
Direct Sampling
Content : Over on GitHub user mcogoni (Marco/IS0KYB) has
recently released a new program called Pepyscope . Pepyscope is a
simple and fast panadapter application that is designed to be used
with direct sampling capable RTL-SDR's such as our RTL-SDR Blog V3
units. Like other panadapters you simply connect the IF output from
the hardware HF radio into the input of the RTL-SDR. Then Pepyscope
gives you a waterfall display that helps users to easily visualize
the spectrum.
Title : Uplinking to QO-100 with a LimeNET Micro and LimeRFE
Content : The LimeNet Micro is a is a $329 board that combines a
Raspberry Pi 3 (compute module) together with a LimeSDR radio. The
LimeRFE is an amplifier and filter board accessory designed to be
used with LimeSDR units. When a LimeNET Micro and LimeRFE are used
together, it is possible to create a transmit capable radio system
that can be used for amateur radio.
Title : SignalsEverywhere: Driving around with KerberosSDR and
Locating a P25 Transmitter
Content : On this weeks episode of SignalsEverywhere, host
Corrosive tests out our KerberosSDR coherent RTL-SDR unit for radio
direction finding. If you didn't already know KerberosSDR is
our experimental 4x Coherent RTL-SDR product . With it, coherent
applications like radio direction finding (RDF) and passive radar
are possible. Together with the KerberosSDR direction finding Android
app it is possible to visualize the direction finding data produced
by a KerberosSDR running on a Pi3/Tinkerboard.
Title : AIS Share App Updated and Magazine Article
Content : Thank you to Christian, programmer of the AIS Share
Android App for letting us know about some updates to his AIS Share
Android application. AIS Share is a €2 app for Android that
allows you to turn an Android device into an AIS receiver together
with an RTL-SDR. AIS stands for Automatic Identification System and
is used by ships to broadcast their GPS locations in order to
help avoid collisions and aide with rescues. An RTL-SDR with the
right software can be used to receive and decode these signals,
and plot ship positions on a map.
Title : RTL-SDR.COM GOES 16/17 and GK-2A Weather Satellite Reception
Comprehensive Tutorial
Content : GOES 16/17 and GK-2A are geosynchronous weather satellites
that transmit high resolution weather images and data. In particular
they are far enough away from the earth to be able to take beautiful
'full disk' images which show the entirety of one side of the
Earth. As these satellites are in a geosynchronous orbit, they can
be counted on to be in the same position in the sky at all times,
so no tracking hardware is required and images can be pulled down
constantly throughout the day without having to wait for a polar
orbiting satellite to pass over like you would with the NOAA APT
or Russian Meteor satellites.
