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:
