Title : Using an RTL-SDR to Monitor A Tire Pressure Sensor used in
Home Brewing
Content : Over on YouTube Andreas Spiess has been helping his
friend create a pressure monitoring system for his home brew beer
bottles. In order to do this, Andreas uses an externally mounted
after market wireless tire pressure sensor whose data can be received
with an RTL-SDR and the rtl_433 decoder software. Modern vehicle
tires contain a TPMS (tire pressure monitoring system) sensor, which
keeps track of tire pressure, temperature and acceleration. The data
is wirelessly transmitted via 433 or 315 MHz to the cars dashboard
and computer for safety monitoring.
Title : NOAA-APT Software Decoder: Users Guide Now Available
Content : Back in August, 2018 we posted about NOAA-APT, which
back then was a new NOAA APT image decoder program. Recently Martin,
the author of NOAA-APT has written in and wanted to note that he's
now created a guide and video tutorials for his software, and for
NOAA APT reception in general .
Title : Using a LimeSDR Mini in SDR#
Content : Thank you to Steve Bossert who wrote in and wanted to
share his notes about getting a LimeSDR Mini SDR to run in SDR#
. The LimeSDR Mini is a $159 RX and TX capable SDR with 12-bit
ADC, 10 MHz to 3.5 GHz tuning range and up to 30.72 MHz of live
bandwidth. We have a short review of it available here .
Title : QIRX SDR Now Shows Received DAB Transmitters on A Map
Content : QIRX SDR is an RTL-SDR compatible program that focuses
on DAB+ decoding and listening. In a recent update programmer Clem
notes that the newest feature is a map powered by OpenStreetMap that
can display a the location of received DAB stations . He writes
Title : SDRPlay Hamvention Demo of SDRUno and RSPDuo Diversity
Features
Content : At this years Hamvention Chris Howard from ICQ Amateur
interviewed Andy at the SDRplay booth. In the interview they discuss
various new features and improvements to SDRuno, the official
software for SDRplay devices.
Title : Using a HackRF to Reverse Engineer and Control Restaurant
Pagers
Content : Several years ago back in 2013 and 2014 we uploaded two
posts showing how it was possible to use an SDR to listen in to
restaurant pagers and collect data from them , and also to spoof
their signal and activate them on demand . If you were unaware,
restaurant pagers (aka burger pagers), are small RF controlled
discs that some restaurants hand out to customers who are waiting
for food. When the food is ready, the pager is remotely activated
by the staff, and then flashes and buzzes, letting the customer
know that their order can be picked up.
Title : Airspy HF+ Discovery Now Available for Preorder + Brief
Initial Review
Content : The Airspy team have recently announced the release
of their new "Airspy HF+ Discovery" . The Discovery is a smaller,
lighter and improved version of the Airspy HF+. The frequency
range, bandwidth and bit depth and specs all remain the same,
but there are some improvements to the dynamic range due to the
addition of preselectors. The original Airspy HF+ was released
back in mid-2017 and it still is in our opinion one of the best
low cost HF DX SDRs because of its very high dynamic range design,
so strong interfering signals are not much of a problem. We have a
previous review of the Airspy HF+ available here were we compare
it against a number of other HF SDRs.

Title : Short Article Explaining DSP Basics Without Math
Content : If the math behind software defined radio and digital
signal processing (DSP) concepts does your head in, the RSGB has a
short document that explains core DSP concepts without any math. If
you're just looking for an overview of what terms like sampling,
nyquist, aliasing, number of bits, undersampling, digital filters
and fast fourier transform mean, then this short article is a great
start.
