May 2022 – RF: It’s Everywhere.  An introduction to SDR – UPDATE!

Now Includes Hands-On Workshop – BYOD!

For the month of May RISE is going on the air!  Well not really, but we are gonna talk about it.  Darrell Little a member of the local amateur radio club is going to talk to us about radio frequencies and software defined radios.  SDR (for those that might not know) is taking a traditional hardware-based radio system and translating that into software whereby it can be leveraged by a PC or Laptop.  In this talk Darrell is going to take us through the basics and then discuss how these systems are used.  This will be an important talk to those that need to be prepared for DR situations or natural disasters.  As always, the talk and beverages are free so come on out and catch some waves… Radio Waves! 

Just added this week – Tom Weeks (aka TWeeks) will be bringing GQRX software and RTL-SDR devices for us to play with in real time. Make sure to bring your laptop, or mobile device to participate.

RF: It’s Everywhere.  An introduction to SDR
A brief review of radio frequencies – part of the electromagnetic spectrum. What are traditional radio receivers and transmitters and what is SDR (software-defined radio). Beyond basic communications, take a look at how RF is used in business, industrial and medical applications. Then comparing some of the reasonably priced SDR devices available for research and testing use, along with the software tools to implement these devices.
