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

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.
Title : A More In-depth Look at the Tunisian RTL-SDR Espionage Story
Content : The Africa Report, an online newspaper specializing in
African stories recently ran a story titled "A Tunisian spy story"

of a UN expert in Tunisian, supposedly for having used an RTL-SDR
dongle as part of his research into violations of the UN arms
embargo on Libya. See our previous post for the original details.

Content : Over on YouTube Corrosive from the SignalsEverywhere
channel has uploaded a new video showing us how to set up P25
trunking and decoding with DSDPlus Fastlane and only a single
RTL-SDR.
Title : Osmocom Now Releasing Weekly Windows Binaries for RTL-SDR
and Osmo-FL2K

project and the Osmo-FL2K discovery. In a recent announcement they
have noted that they are now publishing weekly binary builds for
the RTL-SDR and Osmo-FL2K projects . This means that Windows users

From the Pro 350 Pocket Service Guide, p. 49, Step 5 of the instructions on
removing an I/O board from the card cage, comes a new experience in sound:
5. Turn the handle to the right 90 degrees. The pin-spreading
sound is normal for this type of connector.
