Missed a show? We got you covered! Here is @Daz (from discord) repo of past airings of some select shows. Feel free to take a listen!
I’ve been using the RTL-SDR dongle and a Nooeelc HamItUp+ Upconverter for the better part of a year for various projects and shortwave listening. I think they’re great devices, especially for the price point. Recently, I purchased an Airspy HF+ Discovery in an attempt to upgrade my listening experience, particularly on the HF / shortwave bands. The following is one of many tests that I’ll be conducting to compare the three devices.
RTL-SDR v3 Nooelec HamItUp+ UpConverter Airspy HF+ Discovery 9:1 balun Fencetenna connected to balun with wires as follows: 1x 100ft 16 AWG wire that is 2ft off the ground 1x 100ft 16 AWG 6ft off the ground with another 100ft 22 AWG magnet wire extension that is attached to the second story of my house at about 20ft SDR-Console V3 One caveat is that my tests are in no way scientific and it’s mostly based on my experience with signal, noise, and audio.
Formerly known as the International Shortwave Broadcast Guide, Gayle Van Horn has released her latest edition of the Global Radio Guide: Summer 2020. This is a great resource for information about radio listening on AM, longwave, and shortwave radio stations all around the globe. The book is part reference and part editorial content that is relevant for all types of listeners. You will find a number of great articles from various authors in the radio world as well as a 24 hour frequency guide for more than 500 stations.
This latest edition goes into detail about SDR listening and hardware. In specific, the book reviews the Airspy HF+ Discovery and the RSPdx devices.
If you have not tried some of the different ways to browse and parse radio schedule data, here is your chance to follow along. First, you are going to want to install Java from https://www.java.com/en/download/win10.jsp (I use Windows 10. Download the version for your operating system.) Then you are going to want to pull down the schedule in a special format to manipulate later on in this post. You can get it here http://www.eibispace.de/dx/eibi-radioexplorer-a20.zip . DO NOT UNZIP OR EXTRACT THE ZIP FILE FROM eibispace.de. Next, download Radio Explorer fromhttp://www.radioexplorer.com.ru/en/download.html . Unzip and extract this zip file to the same folder with the eibi-radioexplorer-a20.
Hello everyone! This is a project i have started involving the ISS Space station voice and APRS traffic. Below you will see SDRuno and the RSP1a at work to capture these ISS transmitters. I use the Windows 10 Satellite Tracker app to monitor the ISS location and orbit
EAMs are frequently read on the HF-GCS frequencies and usually won’t take you long to hear one. They begin with a 6 letter header, this preamble could have a few different uses, but NPS states for Minuteman Missile launches “The preamble told the crew which edition and page number of a non sealed authenticator to use. Once at the right page the crew would know what message checklist to use.” The receiving crew has access to an emergency action checklist binder where the message and instructions are copied to. Then the message continues afterward and is repeated.
