An Expansion Board with SMA Output for the Raspberry Pi and RPiTX
					
Thank you to Ihar Yatsevich for writing in and sharing his open 
source project called "rpitx-coax-pcb" which is an expansion board 
for the Raspberry Pi that converts the GPIO pin used by RPiTX into a 
coaxial SMA connector for easily connecting the output to an antenna. 
He notes that there are two revisions. One includes

Decoding Multiple Pager Transmissions Simultaneously with GNU 
Radio
					
A few weeks ago we posted about "LikWidChz"'s work on using GNU 
Radio to channelize multiple NRSC-5 HD-Radio transmissions for 
simultaneous decoding with GNU Radio and an RTL-SDR. He has now also 
submitted a way to channelize pager traffic. He writes: Quite a while 
ago I wanted to decode pager traffic, specifically Flex. When I

Exploring 433 MHz Devices in the Neighborhood with RTL-SDR and 
rtl_433
					
Over on his YouTube channel CWNE88 has posted how he has been 
using and RTL-SDR with the rtl_433 software to explore the data 
coming in from various 433 MHz ISM band devices in his neighborhood. 
In the video he explains how he has set up rtl_433 on his Raspberry 
Pi, and what sort of data

yellowShoes: A Browser Based HD Radio / NRSC-5 User Interface
					
Thank you to Evuraan for writing in and sharing his new browser 
based HD Radio / NRSC-5 interface for the nrsc5 decoder which he has 
called yellowShoes. NOTE: We have been informed by some users that 
yellowShoes may contain a Trojan virus. This is likely to be a false 
positive which is a very common

Cloning A Garage Key with RTL-SDR, Universal Radio Hacker and an 
Arduino
					
Over on YouTube Adam Loboda has uploaded a video showing the full 
steps that he's taken to reverse engineer and clone a wireless garage 
door key using an RTL-SDR and Arduino. He starts by using the 
Universal Radio Hacker software to record a copy of the wireless 
signal generated by the garage key. Using the

Migou: A Low-Power Hybrid Radio Platform
					
Thank you to Ramiro Utrilla Gutierrez a PhD Candidate researcher 
at Universidad Politecnica de Madrid for writing in and sharing his 
research groups work on a low power SDR radio platform called 
"Migou". The basic idea is to combine software defined radio which is 
flexible but power hungry, with less flexible but power efficient 
hardware

CENOS Launches Affordable And Easy-to-use Simulation Software For 
Antenna Design
					
Over the past few months we have posted a few times about the 
beta of CENOS, a new antenna modelling and simulation design package. 
Recently CENOS has exited it's beta testing phase, and they have put 
out a press release about the first release. Of most importance is 
that the software is affordable for hobbyist's,

Raspberry-NOAA V2: Raspberry Pi Automated NOAA and Meteor Weather 
Satellite Capture
					
Raspberry-NOAA is open source code and a set of scripts that 
allows you to set up a Raspberry Pi as an automated NOAA and Meteor 
weather satellite station with an SDR like an RTL-SDR. The software 
makes use of the Raspberry Pi version of WXtoIMG and meteor_decoder 
for decoding the satellites, a program called predict
