Title : Hacking a Ceiling Fan Radio Control Signal with an RTL-SDR
Content : Over on YouTube "River's Educational Channel" has
uploaded a video showing how he was able to reverse engineer the
wireless control signal from his ceiling fan remote, and use that
information to create a new transmitter controlled via his smart
home's Raspberry Pi.
Title : FengYun-2G Confirmed to be Receivable with a WiFi Grid Dish
Content : Back in November 2020 we posted about the release of
a decoder for the FengYun line of geostationary weather satellites
which provide full disk images of the Earth and are positioned to
cover parts of Europe, Africa, the Middle East, Asia, Russia, and
Australia. Back then only a few people had attempted decoding this,
and it was believed that a 120cm satellite dish or larger would
be required.
Title : SATRAN: An Affordable Motorized Satellite Antenna Rotator
Content : Recently we came across the SATRAN project by Daniel
Nikolajsen, which is an attempt to design, build and sell low cost
kits of an automatic motorized satellite antenna rotator for less
than US$200. A motorized satellite antenna rotator is useful for
pointing high gain directional antennas such as a Yagi or satellite
dish at low earth orbit satellites which can move across the sky
quickly. This is also an idea used by the well known SATNOGS project
which also provides a design for a 3D printed antenna rotator,
and runs servers that archive received satellite data.
Title : Using SDR to Investigate Telemetry Still Broadcasting from
1960’s Satellite Transit-5B5
Content : Thank you to Derek @ok9sgc for pointing us to some work
Reddit user u/Xerbot has been doing on receiving telemetry coming
down from a "dead" 1960's satellite called Transit-5B5 . The fleet of
Transit satellites was used for military navigation with the first
launch in 1959 and the last in 1988. All in the fleet have since
died apart from Transit-5B5 which continues to transmit telemetry
at 137 MHz when receiving power from in the sun. Derek writes:
Title : Etherify Talk from The rC3 Online Conference
Content : The "Chaos Computer Club (CCC)" have recently been
uploading videos to YouTube from their "Remote Chaos Experience
rC3" online conference. One talk is by Jacek Lipkowski (SQ5BPF)
who presents his Etherify project which we have posted about a
few times on this blog already. Etherify is a program that allows
users to exploit unintentional RF leakage from Ethernet hardware
in order to transmit data over the air, essentially creating a
primitive software defined radio. In particular the Raspberry Pi
4 was found to have extreme unintentional leakage, with the signal
being receivable from over 50m away.
Title : NanoVNA V2 Enclosure and Carry Case Now Available on our
Store with Release Discount
Content : We have just release for sale our latest product which
is an enclosure and carry case for the NanoVNA V2. It is currently
on sale until the end of this week for US$14.95 including free
shipping from China to most countries. At the end of the sale the
price will rise to US$19.95. Amazon will be stocked in 2-4 weeks,
but will not be on sale. Please visit our store at:
Title : The R860 will replace the R820T2 – Same chip different
name
Content : We have recently received samples and tested the new R860
tuner chip from Rafael Micro. However, to be clear there is no
change in terms of silicon or performance between the R820T2 and
the R860. It is just a change in name signifying a minor change in
the manufacturing chain which has allowed production of this chip
to continue. In the future all R820T2 RTL-SDRs will transition to
the R860 and we are just noting this now so that customers are not
surprised if they see R860 markings on future dongles. We warn
that some sellers of RTL-SDRs may attempt to market the R860 as
an improvement, but we want to make clear that they are indeed
identical to the R820T2.
Title : SignalsEverywhere: A Front End GUI Control Head for OP25
Content : Sarah from the SignalsEverywhere YouTube channel is back
and this time showing off a new program she has created called "Pi25"
or " OP25 Mobile Control Head ". The program is a Python GUI for OP25
which runs on almost any platform including Android and Windows.
OP25 is an advanced open source digital voice P25 Phase 2 capable
decoder which can be used with an RTL-SDR and run on a Raspberry Pi.

Algunos encuentran el silencio insoportable porque tienen demasiado ruido
dentro de ellos mismos.
