    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.
