Title : Radio Analyser: New Program for Plotting DSDPlus Statistics
Content : Thank you to Matthew Cowley for submitting news about his
new program called "Radio Analyser" . Radio Analyser is a program
that imports DSDPlus radio and group files into a postgresql
database. The data can then graphed on the web interface allowing
you to view talk group and radio statistics. DSDPlus is a program
that can be used to listen in to digital P25, DMR and other digital
voice protocols with an RTL-SDR or similar SDR.

Title : Reprogramming a €15 USB Audio Dial to work as an SDR
VFO Knob
Content : Thank you to Tysonpower (aka Manuel DO5TY) for submitting
information about how he's managed to convert a cheap €14.33 USB
audio control dial into a VFO tuning knob for use in SDR programs
like SDR-Console V3. He writes:
Title : Experimenting with an Ultrasonic Sensor Connected to an
Airspy HF+
Content : Software defined radios can have many more applications
other than just radio. For example, it's possible to connect an
ultrasonic sensor which outputs a waveform at some frequency above DC
directly to the input of an SDR. We can then simply treat the sensor
output as an RF signal, and view it in any SDR compatible software
that shows us a spectrum. Normally you'd use a microcontroller with
ADC to process the output of these sensors, but using an SDR makes
visualizing and experimenting with these sensors much easier.
Title : SignalsEverywhere: The Ethics of Decoding and Sharing
Private Information with SDRs
Content : Over on the SignalsEverywhere YouTube Corrosive has
uploaded a new video that addresses the ethics about decoding
private information with SDRs. The radio spectrum is full of
private communications with little to no security around it. For
example hospital pagers in many countries and cities are completely
unencrypted and easily decoded by anyone who can run a radio and
install software on Windows. These messages often contain very
private patient data. Another example he gives is Inmarsat AERO
Medlink voice communications, and how he's seen full phone calls
being shared online.
Title : Tech Minds: LoRa Text Chat with Two Othernet Dreamcatcher
Boards
Content : Back in the middle of last year we posted about
Othernet's Dreamcatcher hardware and the LoRa chat application. The
Dreamcatcher is Othernet's receiver and computing platform that
is designed for receiving their satellite data broadcast. It is
currently available for US$79.
Title : RTL-SDR and HackRF Used in Mr. Robot – A TV Drama
About Hacking
Content : A few readers have written in to let us know the
role SDRs played in the last season of "Mr. Robot". The show
which is available on Amazon Prime is about "Mr. Robot", a young
cyber-security engineer by day and a vigilante hacker by night. The
show has actual cyber security experts on the team, so whilst still
embellished for drama, the hacks performed in the show are fairly
accurate, at least when compared to other TV shows.
Title : Building a FossaSat-1 LoRa IoT Ground Station
Content : FossaSat-1 is a recently launched open source
"picosatellite" with an onboard LoRa repeater designed for Internet
of Things (IoT) communications. It was launched via the Electron
Rocket in New Zealand on December 6. At only 5 x 5 x 5cm in size and
250g in weight, a picosatellite is a tiny satellite that fits in your
hand and can be affordably built and launched for around US$40k.
Title : Passive Doppler Aircraft Scatter with a VOR Beacon and
an RTL-SDR
Content : Over on YouTube Meine Videokasetten has posted a
video showing how he's been using an RTL-SDR to detect aircraft
landing and taking off via the scatter on a VOR beacon. VOR
(aka VHF Omnidirectional Range) is a navigational beacon that is
transmitted between 108 MHz and 117.95 MHz from a site usually
at an airport. Although as it is an older technology it is slowly
being phased out in some places.
