Title : Reviews of the NanoVNA: An Ultra Low Cost $50 Vector
Network Analyzer
Content : A vector network analyzer (VNA) is an instrument that
can be used to measure antenna or coax parameters such as SWR,
impedance and loss. It can also be used to characterize and tune
filters. It is a very useful tool to have if you are building and
tuning home made antennas, filters or other RF circuits. For example
if you are building a QFH or ADS-B antenna to use with an RTL-SDR,
a VNA can help ensure that your antenna is properly tuned to the
correct frequency. Compared to a standard SWR or network analyzer
a VNA supplies you with phase information as well.
Title : WebWSPR: A Browser Based WSPR Decoder and Visualization Tool
Content : A few days ago we posted about [dj0abr / Radio
Electronics'] WebSDR software for QO-100. Having looked through
his GitHub we've seen that he also has an a similar browser based
server tool called WebWSPR for WSPR decoding and visualization
(click with WebWSPR link) which was released earlier this year.
Title : Hackaday Article about the Slow Death of NOAA-15
Content : If you've been following our blog, or have your own
RTL-SDR based weather satellite station, then you'll know that the
NOAA-15 APT satellite has been experiencing issues lately. There
appear to be problems with it's camera scan motor resulting from
it running low on lubrication. This is fully understandable as the
satellite is 21 years old and well past it's expected life span. The
satellite appears to be working some days, and producing garbage
image other days.
Title : Talks from GNU Radio Days 2019
Content : GNU Radio Days 2019 was a workshop held back in
June. Within the last week recordings of the talks have been uploaded
to YouTube by the Software Defined Radio Academy channel. The
talks cover a wide range of cutting edge SDR research topics and
projects. Many of the presenters have also made use of RTL-SDR
dongles, as well as other higher end SDRs in their research.
Title : Building a DIY 2.4 GHz Helical Feed for the
QO-100/Es’Hail-2 Satellite
Content : Over on his YouTube channel Adam 9A4QV has uploaded
a short video that demonstrates his 2.4 GHz homemade helical feed
designed to be used with a reflector (prime feed satellite dish)
for QO-100/Es'Hail-2 satellite reception. The antenna is made
from an old can, 2-turns of copper wire, and a plastic insulator
to hold the turns in place. The two turns are wound in left hand
circular polarization (LHCP), because when used with a satellite
dish reflector it will result in right hand circular polarization
(RHCP), which is the polarization QO-100 uses.
Title : Android ADS-B Flight Tracker with 3D Aircraft Display
Content : ADSB Flight Tracker is an Android App that allows you
to display ADS-B flight data in either 2D or 3D. It works either
with data shared from others over the internet via aggregation sites
like adsbexchange.com , or via your own home ADS-B receiver data
coming from an RTL-SDR and dump1090 server on your home network. You
can also directly connect to an RTL-SDR that is running on your phone
and this will allow you to get data faster with less lag. Using
data shared by others from the internet could have a delay of a
few seconds.
Title : SDRTrunk 0.4.0 Alpha 9 Updates Highlighted
Content : You may recall that a few years ago we released a tutorial
on how to set up and use [ SDRTrunk ]. Fast forward a few years
and the software has seen numerous changes. This application was
designed primarily for tracking trunking radio systems but also
has the ability to decode things like MDC-1200, LoJack and more.
Title : GNU Radio 3.8.0.0 Released – First Minor Release
Version in Six Years
Content : GNU Radio is an open source digital signal processing
(DSP) toolkit which is often used to implement decoders, demodulators
and various other SDR algorithms. Several SDR programs are based on
GNU Radio code, and it is responsible for a lot of DSP development
and knowledge within the SDR and radio community. It is compatible
with almost all SDR devices, including the RTL-SDR.
