Title : rtl-sdr.com
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.
Title : Airspy HF+ Discovery: Collection of Tests and Reviews
Content : The Airspy HF+ Discovery is a new US$169 software
defined radio that recently began shipping. On HF it can tune
from 0.5 kHz to 31 MHz, and on VHF from 60 to 260 MHz.
Title : Automatically Photographing Passing Aircraft with an RTL-SDR,
Pi 3, and IoT Software
Content : Arun Venkataswamy has recently completed a write up about
his system which automatically captures images of passing aircraft
. It works by using a Raspberry Pi and RTL-SDR to listen to ADS-B
broadcasts from aircraft. These broadcasts contain the live current
location and altitude of all aircraft in his area. When a landing
aircraft is detected to be passing near his house, the Raspberry
Pi sends a signal to another Raspberry Pi connected to a camera on
his balcony, and that snaps a photo of the passing aircraft.
Title : Mike Tests out L-Band STD-C and AERO with a Low Cost Modified
GPS Antenna
Content : SDR-Kits.net have begun selling low cost GPS antennas
that are modified to receive the Inmarsat satellite frequencies
between 1535 MHz to 1550 MHz . They also have a version for Iridium
satellites that receives 1610 MHz to 1630 MHz . The antennas are
powered by a 3-5V bias tee, so they should work fine with SDRplay,
Airspy and RTL-SDR Blog V3 units.
Title : Podcasts: GNU Radio with Ben Hilburn + New Signals and
Bits Episodes
Content : The Scanner School Podcast has recently released a new
episode featuring an interview with Ben Hilburn, President of the
GNU Radio project . If you want to understand what GNU Radio is,
and what role it plays in the SDR/radio world, then this is a good
listen.
Title : PEPYSCOPE: A Simple Panadapter for HF Radios using RTL-SDR
Direct Sampling
Content : Over on GitHub user mcogoni (Marco/IS0KYB) has
recently released a new program called Pepyscope . Pepyscope is a
simple and fast panadapter application that is designed to be used
with direct sampling capable RTL-SDR's such as our RTL-SDR Blog V3
units. Like other panadapters you simply connect the IF output from
the hardware HF radio into the input of the RTL-SDR. Then Pepyscope
gives you a waterfall display that helps users to easily visualize
the spectrum.
Title : Uplinking to QO-100 with a LimeNET Micro and LimeRFE
Content : The LimeNet Micro is a is a $329 board that combines a
Raspberry Pi 3 (compute module) together with a LimeSDR radio. The
LimeRFE is an amplifier and filter board accessory designed to be
used with LimeSDR units. When a LimeNET Micro and LimeRFE are used
together, it is possible to create a transmit capable radio system
that can be used for amateur radio.
