Title : Hacking Iridium Satellites With Iridium Toolkit
Content : Over on YouTube TechMinds has uploaded a video showing
how to use the Iridium Toolkit software to receive data and
audio from Iridium satellites with an Airspy. Iridium is a global
satellite service that provides various services such as global
paging, satellite phones, tracking and fleet management services,
as well as services for emergency, aircraft, maritime and covert
operations too. It consists of multiple low earth orbit satellites
where there is at least one visible in the sky at any point in time,
at most locations on the Earth.
Title : KerberosSDR Batch 2 Ships Soon! Pricing will Rise on Monday
Content : KerberosSDR Batch 2 will begin shipping very soon! Thank
you to all who have supported this project so far. If you didn't
already know KerberosSDR is our experimental 4x Coherent RTL-SDR
product made in partnership with Othernet . With it, coherent
applications like radio direction finding (RDF), passive radar and
beam forming are possible.
Title : RTL-SDR Blog V3 X-Rayed
Content : Over on Reddit user u/isysopi201 has put up a
fun post showing what an RTL-SDR Blog V3 looks like under an
X-Ray machine . With the full resolution images, it is possible
to see the PCB traces in internal planes, the windings on the
electrolytic capacitor, inductors, USB choke and direct sampling
matching transformer, as well as the bond wires on the RTL2832U
and R820T2 silicon chips that connect the pins to the silicon.
Title : Testing for Spurious Signals on the Airspy HF+ Discovery
Content : Thank you to Nils Schiffhauer (DK8OK) for submitting
an article documenting his tests on the Airspy HF+ Discovery (
pdf mirror ). Spurred on by discussions on the SDR-Console mailing
list, Nils went looking for issues with spurious signals generated
by the HF+ itself. In the end he finds some minor spurious signals,
but notes that they have absolutely no adverse effects once an
antenna is connected.
Title : Transmitting WSPR on QO-100 with a moRFeus and less than
4 mW Power
Content : Thank you to Zoltan for submitting a short post
about using a moRFeus to uplink WSPR to the Es'Hail-2 (QO-100)
geostationary satellite with amateur radio repeater . moRFeus is
a versatile US$99 signal generator and frequency mixer that can
be controlled either by it's built in LCD screen, or via software
on a Windows or Linux PC. It can generate a clean low phase noise
tone anywhere between 85 to 5400 MHz, and can be used as a mixer for
upconverting or downconverting signals. We have discussed moRFeus
a few times before on this blog as we think it's a useful tool.
Title : Cleanly Embedding an RTL-SDR in an FT-991A With No Extra
Cables
Content : GPIO Pins Used on the RTL-SDR Blog V3
Title : SignalsEverywhere: Harold’s Mobile SDR Vehicle Load
Out for Amateur Radio
Content : This week on the SignalsEverywhere YouTube channel Harold
shows us the mobile SDR and ham radio setup that he's installed on
his car. On the roof of his car he's installed several antennas
for various amateur radio bands including the 1.25m, 2m, 70cm,
33cm bands, a modified GPS puck antenna for Inmarsat and Iridium
reception, and an antenna and GPS pick dedicated for APRS.
Title : Calculating Coax Length by using a NanoVNA as a Time-Domain
Reflectometer
Content : Earlier in the month we posted about the NanoVNA,
an open source VNA project by @edy555 and ttrftech that has
recently become extremely affordable at US$50 for a fully assembled
unit thanks to Chinese manufacturing.
