Title : rtl-sdr.com
Title : POLL: What do you want in a future low cost SDR?
Content : We've decided to ask the community what sort of radio
would be more popular for a ~$30 RX-only SDR. Note that thus far this
is only a hypothetical SDR that does not yet have any designs. We
are just feeling for what's most interesting to people and exploring
for future ideas which may not even be feasible at this time.
Title : Decoding the Lucky-7 Cubesat
Content : Lucky-7 is a Czech cubesat that carries some interesting
sensors including a low power GPS receiver, a gamma ray spectrometer
and dosimeter and a photo camera. The creators also claim that
it is "probably the lowest-cost scientific space mission in human
history". It was recently successfully launched and orbited together
with the Meteor M2-2 weather satellite and several other small
satellites.
Title : SignalsEverywhere: Satcom Antennas for L-Band Reception
via RTL-SDR + Podcast on the MiTee CubeSat Project
Content : On this episode of SignalsEverywhere on YouTube
Corrosive shows off several antennas that can be used for Inmarsat
and Iridium satcom reception. His video shows off a commercial
Inmarsat branded satlink antenna which is designed to be used on
moving ships, a grid dish antenna, a custom QFH iridium antenna made
from a repurposed Vaisala radiosonde, a commercial Iridium patch,
an older Outernet/Othernet Iridium patch and a custom Iridium patch
that Corrosive built himself.
Title : Dronesense: A LimeSDR Based Drone Detector and Jammer
Content : Over on the LimeSDR CrowdSupply blog, Ogün Levent has
submitted a short article about his "Dronesense" project . Dronsense
is a spectrum-scanning and jamming system based on the LimeSDR. The
LimeSDR is a US$299 12-bit TX/RX capable SDR that can tune between
100 kHz – 3.8 GHz, with a maximum bandwidth of up to 61.44 MHz.
Title : SDR-Makerspace Talk: Evaluation of SDR boards and toolchains
Content : The Software Defined Radio Academy YouTube
channel recently uploaded an interesting talk by Alex Csete
(creator of the popular GQRX and GPredict applications), and
Sheila Christiansen. Their presentation discusses their work with
the European Space Agency (ESA), Libre Space Foundation and how
they are running SDR Makerspace's that are helping students create
and track cubesats. During the talk Alex and Sheila also describe
various SDR hardware, and how they test them for their purposes.
Title : A Demonstration of RSPDuo Diversity Being used to Cancel
Local Interference
Content : SDRPlay have recently published a video demonstrating
how the new RSPduo diversity feature in SDRUno can be used to
cancel local interference. 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. The RSPDuo's diversity feature allows us to either
combine two antenna signals together for an up to 3 dB increase, or
for removal of an unwanted noise source via subtraction of signals.
Title : Weather Satellite NOAA 15 Appears to have Failed (Again)
Content : Back in April 2018 we posted how the NOAA-15 APT
weather satellite that many RTL-SDR users enjoy receiving images
from was having problems with it's scan motor resulting in image
errors. The satellite recovered from that problem, but today the
problem appears to be back and in a much worse way now.
Title : Atomic Radio: Quantum Laser Based Radio Reception
Content : Software defined radio (SDR) is a relatively new
technology that has impacted the world of radio technology in many
ways. But beyond SDR, there are still some other very interesting
radio technologies being worked on, such as "Atomic Radio" a.k.a
"Quantum Radio".

Hall's Laws of Politics:
(1) The voters want fewer taxes and more spending. (2) Citizens
want honest politicians until they want something
fixed.
(3) Constituency drives out consistency (i.e., liberals defend
military spending, and conservatives social spending in their
own districts).
