Title : Creating Wide Area Composite Images with WXtoIMG + Weather
Satellite Failure Updates

Content : With so many independent people receiving weather
satellite images from the NOAA satellites daily, an interesting
collaborative task is to stitch these images together to create
a wide area composite image. Fortunately the WXtoIMG software
already has stitching as a feature.

Title : Using an RTL-SDR, RF Fingerprinting and Deep Learning to
Authenticate RF Devices

Content : Every device that transmits radio waves has a unique and identifiable RF fingerprint which occurs due to the very slightly
variations in the hardware manufacturing process. This means that
devices using identical transmitters of the same make and model
can still be differentiated from one another.

Title : LimeRFE WSPR Tests

Content : The LimeRFE is a power amplifier and filter bank solution
designed for the low cost TX capable LimeSDR software defined
radios. It has multiple bands from HF all the way up to 3.5 GHz,
and is capable of putting out about 2W on the HF bands. Currently
LimeRFE is crowdfunding over on CrowdSupply with a cost of US$599
or alternatively there is now a cheaper unit for US$449 without
support for the cellular bands. The campaign is active for 4 more
days from the time of this post, and after that the price is due
to rise by another US$100.

Title : Using SDR For QO-100 Satellite Operation

Content : Es’hailsat, otherwise known as QO-100 is the first geostationary satellite with an amateur radio payload on-board. The
satellite contains both a Wide Band transponder for experimental
modes and DVB-S Digital Television and a Narrow Band transponder
used mostly for SSB voice and some digital mode contacts with other
amateur operators. If you’re unfamiliar with this satellite
we’ve covered it in previous articles, like in [ Es’hail Transponder Now Active ]

Title : Updated Meteor M-N2-2 Tutorial and Decoder Now Available

Content : Thank you to Happysat for submitting the following
information about the updated LRPT decoder for Meteor M-N2-2. He has
also provided a link to his very useful Meteor Satellite reception
tutorial .

Title : Kickstarter for a Lower Cost Laboratory Grade RF Broadband
Noise Generator

Content : UPDATE: John wanted to add the following clarification:


Title : YouTube Video: Information Packed Introduction to SDR

Content : Over on YouTube Nick Black has uploaded a video where
he does a good introduction to software defined radio (SDR), SDR
history, how SDR works, various SDR concepts like sampling and
bandwidth, different SDR hardware, the SDR Linux stack and reverse
engineering wireless signals.

Title : PiSDR Image Gains PlutoSDR Support

Content : [ @Lugigi Cruz ] has announced on twitter that his latest
PiSDR image now includes full PlutoSDR support. PiSDR is a pre-built
Raspberry Pi distribution that supports several SDRs including the
RTL-SDR. It comes with many applications and libraries ready for you
to use some of which include GQRX and GNURadio Companion. PiSDR is
available on [ GitHub ] and just needs to be burned to an SD card
to be used. The PlutoSDR is a low cost (typically priced anywhere
between $99 – $149 depending on sales) RX/TX capable SDR with
up to 56 MHz of bandwidth and a 70 MHz to 6 GHz frequency range.
