Title : SWLing Blog: Building a Homemade YouLoop (Noise-Cancelling
Passive Loop) Antenna
Content : Over on the SWLing Post Blog Thomas has uploaded an
excellent tutorial showing how you can build your own YouLoop (aka
a Noise-Cancelling Passive Loop). If you've been following our
previous posts you'll know that we recently started selling the "
YouLoop " which is designed and produced by Youssef from Airspy. The
YouLoop is a passive loop antenna designed for HF reception, but also
works well up until VHF. The main catch is that you need to use it
with a receiver with a low noise figure front end, like the Airspy
HF+ Discovery (SDRplay units should work well too). The RTL-SDR Blog
V3 in direct sampling mode does somewhat work with it to an extent,
but RTL-SDRs relying on upconverters for HF will probably see poor
results.
Title : Radwave Updates: Browse SETI Spectrum Data on your Android
Device
Content : Back in February 2019 we first posted about Radwave
, an Android SDR App for RTL-SDR dongles. It has some interesting
features not found in other Apps like the ability to easily zoom,
pause and rewind the spectrum at any time.
Title : Starlink Doppler Reflections Caught with an RTL-SDR
Content : Over on YouTube William IU2EFA has been uploading
multiple short "meteor scatter" videos. This involves using an
RTL-SDR to briefly receive distant radio stations via the RF
signal reflecting off the ionized trail left by meteors entering
the atmosphere. However, in a similar fashion satellites orbiting
the earth can also reflect distant radio stations.
Title : The SWLing Post Reviews the YouLoop Passive Loop Antenna
Content : Over on the SWLing (Short Wave Listening) Post blog
Thomas has just uploaded his review of the YouLoop in a post titled
" The Airspy Youloop is a freaking brilliant passive loop antenna
". If you weren't aware, we are currently selling this loop in
our store for US$34.95 incl. free worldwide shipping to most
countries. Sales are currently in pre-order as our first batch
of units ordered sold out within a day, but we're soon going to
receive the second batch in the next few days.
Title : A Homemade Boat Computer with RTL-SDR for Weather Fax,
NavTex and more
Content : Over on Hackaday we've seen a post about [mgrouch]'s
"boat computer" which consists of a Raspberry Pi 4, HDMI display,
and a whole slew of sensors and receivers useful for a marine
environment including an RTL-SDR.
Title : A Comprehensive Lab Comparison between Multiple Software
Defined Radios
Content : Librespace, who are the people behind the open
hardware/source SatNOGS satellite ground station project have
recently released a comprehensive paper (pdf) that compares multiple
software defined radios available on the market in a realistic
laboratory based signal environment. The testing was performed
by Alexandru Csete ( @csete ) who is the programmer behind GQRX and
Gpredict and Sheila Christiansen ( @astro_sheila ) who is a Space
Systems Engineer at Alexandru's company AC Satcom. Their goal was
to evaluate multiple SDRs for use in SatNOGS ground stations and
other satellite receiving applications.
Title : YouLoop Batch 2 Available for Pre-Order: Estimated Shipping
in One Week
Content : A few days ago we posted about our release of the first
batch of YouLoop passive HF/VHF loop antenna kits. We underestimated
the demand and sold out of kits in less than a day! We now have a
second batch currently being manufactured and it should be ready
to ship out in about a week from now (late March/early April).

You plan things that you do not even attempt because of your extreme caution.
