Decoding Voyager 1 Telemetry with GNU Radio
Daniel Estevez often posts on his blog about advanced SDR and
radio experiments he's worked on. In a recent post he describes how
he decoded telemetry from the Voyager 1 spacecraft using GNU Radio.
As Voyager 1 is so far away, and the signal so weak, a rather large
scale 100 meter dish is required

Installing Remote SDR V2 on a Raspberry Pi 4B
Remote SDR V2 is software that allows you to easily remotely
access either a PlutoSDR, HackRF or RTL-SDR software defined radio.
It was originally designed to be used with the amateur radio QO-100
satellite, but version 2.0 includes multiple demodulation modes,
NBFM/SSB transmission capability, CTCSS and DTMF encoders, modulation
compression and a programmable frequency shift

Viewing the RF Spectrum in Virtual Reality + Augmented Reality
EMC Probe
Thank you to Manahiyo for submitting his video which shows his
software that allows the RF spectrum to be viewed in virtual reality,
using a VR headset and an RTL-SDR. In his setup he currently uses a
Oculus Quest 2 VR headset, but it should work with others too. The VR
screen allows you to

Receiving the ‘Hidden’ Broadcast FM SCA Audio
Subcarrier with an RTL-SDR and SDR#
Broadcast FM channels can often contain additional subcarriers
hidden within the bandwidth. A common subcarrier is Radio Data System
(RDS), and this is what provides song and radio station text
information to your radio. Another less commonly seen subcarrier is
the Subsidiary communications authority (SCA), which is a separate
audio channel hidden within the broadcast

DragonOS: RF Propagation Analysis with Signal Server GUI
DragonOS is a ready to use Ubuntu Linux image that comes
preinstalled with multiple SDR software packages. The creator Aaron
also runs a YouTube channel showing how to use the various packages
installed. In his latest video Aaron shows how to use the new
Signal-Server GUI that has recently been added to DragonOS. We posted

SDRSharp Guide V3.0 Released
Paolo Romani (IZ1MLL) has recently released version 3.0 of his
SDRSharp PDF Guide which we posted about last in March of this year.
As before the document is a detailed guide about how to use SDRSharp,
which is the software provided by Airspy. While intended for Airspy
devices, SDRSharp also supports a number of third

A SDR Digital Voice Hotspot with GNU Radio, MMDVM and QRadioLink
Thank you to Adrian (YO8RZZ) for writing in and sharing with us
his article explaining how to use an SDR to set up a digital voice
hotspot for digital voice modes supported by MMDVM such as D-Star,
DMR, System Fusion, P25 and NXDN. Adrian notes that this is possible
with any full duplex SDR such
