Title : PREORDER SALE: Active L-Band 1525-1637 Inmarsat to Iridium
Patch Antenna Set For $34.95
Content : Over the last several months we've been working on a
versatile active L-band patch antenna that can cover Inmarsat to
Iridium satellite frequencies. That antenna is now almost ready,
and should be able to ship out from our Chinese storage warehouse
by week 1 or 2 of October. No other components like filters or
amplifiers are required to be able to use this antenna, as it is
an all in one system.
Title : Monitoring 3D Printer Filament Moisture with an RTL-SDR
and rtl_433
Content : Over on Hackaday we've seen a post about Scott
M. Baker's 3D printer filament drying farm that is monitored by a
433 MHz ISM band sensor and an RTL-SDR running rtl_433. If you're
familiar with 3D printing then you'll know that it is critical to
keep the plastic filament free from absorbing moisture, otherwise
it can cause all sorts of issues when it comes time to print
something.
Title : Vancouver Broadcasts Hospital Patient Data Over Unencrypted
Wireless Pagers
Content : Canadian based researchers from the "Open Privacy Research
Society" recently rang the alarm on Vancouver based hospitals who
have been broadcasting patient data in the clear over wireless
pagers for several years. These days almost all radio enthusiasts
know that with a cheap RTL-SDR, or any other radio, it is possible to
receive pager signals, and decode them using a program called PDW
. Pager signals are completely unencrypted, so anyone can read the
messages being sent, and they often contain sensitive pager data.
Title : Decoding the ARES Train Protocol with an RTL-SDR
Content : Over on YouTube user JellyImages has uploaded a video
demonstrating his Windows based ARESrcvr software. ARES is a railway
control communications protocol used by some trains in the USA.
His code connects to an RTL-SDR dongle, and demodulates the
ARES protocol, providing decoded packets to ATSCMon via UDP on
localhost.
Title : Exploring the Limits of General Purpose SDR Devices
Content : Back in August 2019 the Chaos Communication Camp was
held in Germany. This is a 5 day conference that covers a variety of
hacker topics, sometimes including SDR. At the conference Osmocom
developer Harald Welte (aka @ LaF0rge ) presented a talk titled
"The Limits of General Purpose SDR devices". The talk explains how
general purpose TX capable SDRs like HackRFs and LimeSDRs have their
limitations when it comes to implementing advanced communications
systems like cellular base stations.
Title : YouTube Video: Reverse Engineering with SDR
Content : Over on YouTube Black Hills Information Security (aka
Paul Clark) has uploaded a one hour long presentation that shows
how to use a software defined radio to reverse engineer digital
signals using GNU Radio.
Title : NanoVNASaver Software Walkthrough + NanoVNA Firmware Updates
Bring 1.5 GHz Max Range
Content : The NanoVNA is an open source VNA project by @edy555
and ttrftech that has recently become extremely affordable at
less than US$50 for a fully assembled unit thanks to Chinese
manufacturing (or a little more if you order it via Amazon ).
Title : Reviews of the Low Cost MLA-30 Wide Band HF Magnetic
Loop Antenna
Content : Recently Chinese manufacturers have begun producing
a low cost wide band (100 kHz - 30 MHz) magnetic loop HF antenna
known as the MLA-30. The loop can be found on eBay for under US$45
with free shipping . In the past wide band HF loop antennas have
not been cheap, normally costing $300+ dollars from manufacturers
like Wellbrook.
