OAUSA Net - January 14, 2016 - Software Defined Radio

Post by DaveK » Wed Jan 13, 2016 12:03 pm

This week we will cover a relatively new subject that offers the Amateur community a new approach to communications, using your computer. The ARRL describes SDR:
Software Defined Radio attempts to place much or most of the complex signal handling involved in communications receivers and transmitters into the digital (DSP) style. In its purest form, an SDR receiver might consist simply of an analog-to-digital convert chip connected to an antenna. All the filtering and signal detection can take place in the digital domain, perhaps in an ordinary personal computer. While there are still good reasons to use some analog components in high-performance gear, the SDR approach is becoming more common in Amateur Radio.
The ARRL has an extensive list of sources for further information, and can be found here: http://www.arrl.org/software-defined-radio .

Our guest this week with be Jim Sanders, AG6IF, whose links and pictures are posted below. We have numbered the items for reference during the net.

More to come today!
