    Title : KerberosSDR Batch 2 Ships Soon! Pricing will Rise on Monday

    Content : KerberosSDR Batch 2 will begin shipping very soon! Thank
    you to all who have supported this project so far. If you didn't
    already know KerberosSDR is our experimental 4x Coherent RTL-SDR
    product made in partnership with Othernet . With it, coherent
    applications like radio direction finding (RDF), passive radar and
    beam forming are possible.

    Title : RTL-SDR Blog V3 X-Rayed

    Content : Over on Reddit user  u/isysopi201  has put up a
    fun post showing what an RTL-SDR Blog V3 looks like under an
    X-Ray machine . With the full resolution images, it is possible
    to see the PCB traces in internal planes, the windings on the
    electrolytic capacitor, inductors, USB choke and direct sampling
    matching transformer, as well as the bond wires on the RTL2832U
    and R820T2 silicon chips that connect the pins to the silicon.

    Title : Testing for Spurious Signals on the Airspy HF+ Discovery

    Content : Thank you to Nils Schiffhauer (DK8OK) for submitting
    an article documenting his tests on the Airspy HF+ Discovery  (
    pdf mirror ). Spurred on by discussions on the SDR-Console mailing
    list, Nils went looking for issues with spurious signals generated
    by the HF+ itself. In the end he finds some minor spurious signals,
    but notes that they have absolutely no adverse effects once an
    antenna is connected.

    Title : Transmitting WSPR on QO-100 with a moRFeus and less than
    4 mW Power

    Content : Thank you to Zoltan for submitting a short post
    about using a moRFeus to uplink WSPR to the Es'Hail-2 (QO-100)
    geostationary satellite with amateur radio repeater . moRFeus is
    a versatile US$99 signal generator and frequency mixer that can
    be controlled either by it's built in LCD screen, or via software
    on a Windows or Linux PC. It can generate a clean low phase noise
    tone anywhere between 85 to 5400 MHz, and can be used as a mixer for upconverting or downconverting signals. We have discussed moRFeus
    a few times before on this blog as we think it's a useful tool.

    Title : Cleanly Embedding an RTL-SDR in an FT-991A With No Extra
    Cables

    Content : GPIO Pins Used on the RTL-SDR Blog V3

    Title : SignalsEverywhere: Harold’s Mobile SDR Vehicle Load
    Out for Amateur Radio

    Content : This week on the SignalsEverywhere YouTube channel Harold
    shows us the mobile SDR and ham radio setup that he's installed on
    his car. On the roof of his car he's installed several antennas
    for various amateur radio bands including the 1.25m, 2m, 70cm,
    33cm bands, a modified GPS puck antenna for Inmarsat and Iridium
    reception, and an antenna and GPS pick dedicated for APRS.

    Title : Calculating Coax Length by using a NanoVNA as a Time-Domain Reflectometer

    Content : Earlier in the month we posted about the NanoVNA,
    an open source VNA project by  @edy555 and ttrftech  that has
    recently become extremely affordable at US$50 for a fully assembled
    unit thanks to Chinese manufacturing.

    Title : Decoding PAL Video from a Nintendo with An Airspy SDR Part 2

    Content : Oona combines composite output for color images.
