    Title : SignalsEverywhere: Creating a 2.4 GHz Amateur Television
    Station with a Barbie Camera

    Content : In this episode Corrosive from the SignalsEverywhere
    YouTube channel begins a series on reverse engineering an old 90's
    Barbie branded 2.4 GHz wireless camcorder toy, and using it for
    Amateur Radio TV. The camcorder toy consists of the wireless camera,
    and a base station that plugs into a TV.

    Title : Two Antenna Diversity For the SDRPlay RSPDuo now Available
    in SDRUno

    Content : The SDRplay RSPDuo is a 14-bit dual tuner software defined
    radio capable of tuning between 1 kHz - 2 GHz. It's defining feature
    is that it has two receivers in one radio, which should allow for
    interesting phase coherent applications such as diversity.

    Title : Meteor M N2-2 Successfully Launched: Awaiting LRPT Signal

    Content : On July 5 the Russian Meteor M N2-2 weather satellite was successfully launched into orbit and appears to be healthy. The
    LRPT weather camera signal is not yet broadcasting however, and
    we expect it to still take roughly 1-2 months before it begins (if
    all goes well) as satellites typically run through a long list of
    qualification tests before becoming operational. During this time
    there may be broadcasts of test patterns that can be caught. Meteor
    M N2-2 can currently be tracked in Orbitron and online at N2YO .

    Title : Homebrew SDR Transceiver for HF Operation

    Content : Traditionally when we think about Software-Defined Radio
    we’re thinking about little USB adapters that unlock a world
    of radio in the palm of our hands. This is done by allowing us to
    directly sample the IQ data from the mixer within the SDR.

    Title : KiwiSDR Conference Talks: KiwiSDR and it’s GPSDO,
    TDoA Geo-Location and GNURadio Sources

    Content : Thank you to John ZL/KF6VO (creator of the KiwiSDR)
    for submitting some interesting KiwiSDR related conference talks
    that might be of interest to some readers. If you were unaware 
    the KiwiSDR  is a US$299 HF SDR that can monitor the entire 0 - 30
    MHz band at once. It is designed to be web-based and shared, meaning
    that the KiwiSDR owner, or anyone that they've given access to can
    tune and listen to it via a web browser over the internet. Many
    public KiwiSDRs can be found and browsed from the list at  sdr.hu
     or by signal strength and location  on this website . One of
    the most interesting KiwiSDR features is it's TDoA capabilities ,
    which allow users to geographically locate HF transmitters.

    Title : Solar Sail Satellite Lightsail-2 Now Transmitting Morse
    Code Beacon

    Content : Lightsail-2 is a solar sail experiment which
    successfully launched on a Space-X Falcon Heavy on 25 June, and was
    released into orbit on July 2nd. A solar sail is a type of spacecraft
    that uses a large metallic foil to create propulsion via photons
    from the sun hitting it. Lightsail-2 is still undergoing testing,
    so it has not yet deployed it's solar sail, but recent updates
    indicate that it is healthy.

    Title : SignalsEverywhere: Investigating USGS Gaging Stations and
    their GOES Satellite Connection

    Content : The United States Geological Service maintains over 8500
    "Gaging stations" in bodies of water all over the country. Gaging
    stations are devices that are used to measure environmental data
    such as groundwater levels, discharge, water chemistry, and water
    temperature. What's interesting is that they all upload their data
    in real time to GOES satellites - the same satellites that we can use
    with an RTL-SDR to receive weather images of the entire earth. The
    data is then downlinked in the L-band to the USGS scientists via
    a protocol known as DCP (Data Collection Platform).

    Title : Tracking Company Jets with ADS-B to Give an Edge to Hedge
    Fund Investors

    Content : Financial news site Bloomberg recently ran an article
    about how hedge fund managers are using ADS-B to track private
    company aircraft in order to help predict the next megadeal between
    companies. They explain with an example:
