A New Twist on the Software Defined Radio

Software defined radios (SDR) are not a novel concept; the original concept of a software radio first appeared thirty years ago. Due to the high cost of SDR hardware, though, software radio platforms really haven't been available as 'consumer' devices until recently. The wide availability of software defined radios for students, engineers & scientists, and hobbyists, was really kicked off by Matt Ettus in 2004. Since then, the use of the software defined radio has proliferated through many fields of communications and electronics.

The ISEE-3 Reboot Project: a dream SDR application

Puerto Rico is host to many interesting sights: lush greenery covering rolling hills as far as the eye can see, emergency first responder vehicles that always have their lights flashing even when not on call, the best crab turnovers, and the Arecibo Radio Observatory – the world's largest single-dish radio telescope. As luck would have it, multiple Ettus Research USRP N210s are now connected to the telescope for the purpose of communicating with an all-but-forgotten 36 year old NASA space probe known as the International Cometary Explorer.  

Sunny Days in London are Rare… and a Great Excuse to Geek Out with Some SDR!

During a recent business trip to Europe I had the opportunity to do a bit of sightseeing in London. I was also fortunate enough to visit on a warm sunny day, which has been a bit of a rarity this year. While walking through town, I realized that I had all of the components I needed to do some quick experiments with my SDR (software defined radio) near the important landmarks – Big Ben, the London Bridge, etc. This is a short write-up about my experiences in London, my stop on the "USRP World Tour".

The USRP X Series: A New Standard in SDR

Earlier this month, Ettus Research announced its newest addition to the USRP software defined radio family – the release of the USRP ™ X300 and X310. So far, the community has expressed excitement about the product and its high-performance nature.  We thought we would take opportunity to highlight features, discuss the new applications this series enables, and paint a picture of how it fits into the overall Ettus Research product portfolio.
