Welcome to Signals Everywhere!

If you’re interested in Software Defined Radio and want to learn more about it you’ve come to the right place. Here you’ll find video tutorials, a dedicated podcast and a support forum all here to help you take your SDR game to the next level. 

What is SDR?

Software Defined Radio (SDR) is the next generation of radio communications. It allows you to both transmit and receive (depending on the SDR you get) virtually any frequency or any mode from P25/DMR/DVB-S/ADS-B and more! Allowing you to track aircraft, listen to trunk radio and so much more. All this at a price anyone can afford. SDR reaches into the amateur radio and scanner hobby and takes it by the horns.

Who am I?

My name is Harold Giddings, but you can call me Corrosive. It’s been my online alias for years. (it also happens to be my amateur callsign KR0SIV).

I’ve fallen in love with radio communications, especially Software Defined Radio and I’ve always had a deep desire to share my knowledge. This stuff isn’t always easy so when I learn something new I can’t wait to share it in the hopes I can make something easier for the rest of the community.

Software Defined Radios I Use

Adalm Pluto

This full duplex transmit capable SDR Tunes a range 325Mhz – 3.8 Ghz with software modifications to potentially extend those limites. Great for Amateur Television with software available for DVB-S digital video transmission.

Airspy

A step up from your average RTL you’ll enjoy 3-10Mhz of bandwidth along with built in tracking filters and bias-t support directly from within the SDR# application. The airspy comes in serveral different flavors.

SDRPlay Duo

The Duo is a unique SDR that has the ability to tune two seperate ranges at 2.5 mhz each or a single range up to 10 mhz wide. With the SDRPlay Uno Software you have features not found in any other package.

RTL-SDR Blog v3

Unlike the cheap RTLs you can find on eBay these are high-quality with great cooling a TCXO and enchanged L band performance for satellite reception at an affordable price. These guys work with just about any software you’ll find.

Lime Mini SDR

The value in the full duplex transmit capable Lime SDR comes in the form of software available. You’ll need linux for most appliactions but enjoy the ability to run OpenBTS and other advanced GNURadio applications.

HackRF

This Half-duplex (simplex) transmit capable SDR has an insane 10Mhz – 6Ghz tuning range along with software for fast scanning that entire band to quickly find interference and other signals. Most transmit options will require linux.
