    Title : KerberosSDR App Update: Heatmap + Precise TX Localizing
    & Turn by Turn Navigation Demo Videos

    Content : We have just released an updated version of the
    KerberosSDR Android direction finding app . If you didn't
    already know KerberosSDR is our experimental 4x Coherent RTL-SDR
    product. With it, coherent applications like radio direction finding
    (RDF) and passive radar are possible. Together with the KerberosSDR
    direction finding Android app it is possible to visualize the
    direction finding data produced by a KerberosSDR running on a
    Pi3/Tinkerboard.

    Title : SignalsEverywhere: Creating a DIY Upconverter with a HackRF
    and RF Mixer

    Content : Over on YouTube Corrosive from the SignalsEverywhere
    channel has uploaded a new video showing us how you can make a
    DIY upconverter using a HackRF as a signal source and a cheap $10
    RF Mixer. An upconverter converts lower frequencies into higher
    frequencies. For example, an upconverter is commonly used to convert
    HF signals into VHF, so that VHF/UHF only SDRs can receive HF.

    Title : SignalsEverywhere: Windows 10 usb_open_error -12 Fix

    Content : The process to install an RTL-SDR dongle on Windows
    involves the simple step of running Zadig and installing the generic
    WinUSB drivers to the RTL-SDR, which shows up as "Bulk-In, Interface
    (Interface 0)" in Zadig.

    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 .
