Title : Engineer and Beauty Queen Xyla Foxlin sends an RTL-SDR and
Miss America Crown to Space in a High Altitude Balloon

Content :   Xyla Foxlin  is a Mechatronics engineer, entrepreneur,
and beauty queen who amongst many other titles is also a STEM
YouTuber. In her latest YouTube video Xyla sends her Miss America
crown that she received as winner of Miss Greater Cleveland 2018
to space on a high altitude balloon.

Title : TechMinds: Testing a DC-160 MHz Panadapter Switch

Content :  Over on his YouTube channel Tech Minds has uploaded a
video where he tests out a cheap  US$90 automatic antenna switch
with DC-160 MHz range  that he purchased from Chinese goods retailer
Banggood. An automatic antenna switch like this is required when
wanting to use an SDR such as an RTL-SDR as a panadapter with a
transmit capable radio. The switch will automatically switch the
SDR to ground when transmitting, so that high power does not enter
the SDR via the shared antenna and destroy it.

Title : Evaluating LoRaWAN Security with an RTL-SDR

Content :  Over on their blog Trend Micro have uploaded a post
describing how they evaluated the security of LoRaWAN communications
using an RTL-SDR . LoRaWAN is a wireless communications technology
that allows for Internet of Things (IoT) connectivity at a much lower
cost compared to cellular infrastructure. However, as described
in their post LoRaWAN incorporates very little security, making
connected devices an easy target for hackers.

Title : Scanner School Podcast + Webinar: This is Why You Need an SDR

Content :  Scanner School is an online site providing tutorials,
podcasts and reviews all about the radio scanning hobby. They are
currently planning a Webinar for February 23, 2021 titled "Why Every
Scanner User Needs an SDR: The #1 Underrated Tool that should be in
your setup". You can sign up to the  webinar here . In addition to
the upcoming webinar they have also already  released episode 165
of their podcast  titled "This is Why You Need an SDR". The topics
covered in the podcast are listed below.

Title : Analyzing Frozen Air Traffic in the Hudson Valley

Content :  Thank you to Steve Bossert (K2GOG) for submitting his
article on analyzing traffic from his RTL-SDR based ADS-B receiver
during the recent heavy snow storms  at his location in the Hudson
Valley. His graphs show a huge drop off in air traffic and ADS-B
packets received during the storms.

Title : Generating White Noise with an FL2K Dongle

Content :  The FL2K project allows us to turn a cheap USB 3.0 dongle
into a fully transmit capable SDR (filters still required for high
power work). We have  posted about  the FL2k project several times
on this blog since early 2018.

Title : Getting Started with Developing Plugins for SDR# on .NET 5

Content :  Recently  we posted  about how SDR# was updated to the
latest .NET 5 framework, and this brought with it a new plugin
SDK for developers. If you're wanting to get started with plugin
development, Petri-Veikko Alajärvi (OH1GIU) has  uploaded a
tutorial showing how to get started with the free Visual Studio
2019 Community IDE . His post shows how to create a new project,
how to add references to the SDRSharp plugin files and how to set
up and test a basic GUI via an RDS information display example.

Title : Building an 11.2 GHz Radio Telescope with an Airspy and
1.2m TV Satellite Dish

Content :  In the past we've posted several times about how 1.42 GHz
Hydrogen Line amateur radio telescopes used with RTL-SDRs or other
SDRs for Hydrogen line observations of the galaxy. Recently Hackaday
ran  a post  highlighting a project from "PhysicsOpenLab" describing
an 11.2 GHz radio telescope that uses an Airspy SDR as the receiver.
