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.
Title : Frugal Radio: SDR Guide Ep 9 – P25 LSM Trunking with
one RTL-SDR V3 and DSDPlus
Content : In his latest episode of his SDR Guide series Rob from
Frugal Radio provides a walkthrough on using DSDPlus Fastlane to
decode trunked P25 with just one RTL-SDR V3 dongle. In the video
he explains each of the various DSDPlus windows, and demonstrates
decoding of a Simulcast system in his area.
Title : Using an RTL-SDR as a Panadapter with an Automatic Antenna
Switcher
Content : Over on YouTube "Gadget Talk" has uploaded a useful video
showing how he set up an RTL-SDR V3 based panadapter system to use
with his traditional amateur radio. The setup involves utilizing
an antenna switcher which allows him to transmit with the RTL-SDR
connected to the same antenna. The switch grounds the SDR during
transmission, ensuring that the RTL-SDR is not overloaded with the
transmit signal.
Title : Tech Minds: Decoding Orbcomm Satellites with a Software
Defined Radio
Content : Over on his YouTube channel TechMinds has uploaded a new
video showing how to decode signals from Orbcomm satellites. Orbcomm
run a global network of low earth orbit satellites that perform
services such as Internet of Things (IoT), Machine 2 Machine (M2M)
communications, asset tracking, utilities telemetry, government
communications and much more. The signals can be received at around
137 MHz.
