Title : A Remote ADS-B, ACARS, VDL2 and Air Traffic Control Voice
Monitoring Station with LTE Connection
Content : Over on Reddit u/tsimola has posted about his remote
ADS-B station that is accessed via an LTE connection . When an
opportunity came up to install a remote ADS-B station on a tall
building with unobstructed 360 degree views, tsimola decided to
build the best ADS-B monitoring station that he could, and make
sure that it would be easily to maintain and monitor from afar.
Title : SDRplay RSPDuo Diversity: Combing a Magnetic Loop and
Miniwhip Antenna
Content : The SDRplay team have posted some more videos that
demonstrate the SDRplay Duo's diversity function. The SDRplay
RSPDuo is a 14-bit dual tuner software defined radio capable of
tuning between 1 kHz - 2 GHz. It's defining feature is that it has
two receivers in one radio, which allows us to combine the signal
from two antenna together.
Title : Using an Airspy HF+ Discovery to Hunt for HF Beacons
Content : Over on YouTube Tech Minds has posted a video of him
using an Airspy HF+ Discovery to hunt for signals like non-direction
beacons (NDB's) and other morse code CW beacons. The Airspy HF+
Discovery is a new software defined radio that builds upon the
already excellent original Airspy HF+.
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.
