The TAPR/ARRL Digital Communications Conference (DCC) was held virtually during September 17 - 18 2021 and the live streamed talks are now available on YouTube. DCC is a yearly conference with many SDR and RF related talks, with a focus on ham radio science.
The talks include various updates on the development of the TangerineSDR (an SDR designed for citizen science experimentation), talks on the development of a magnetometer board for citizen science, as various other talks regarding ham radio and ham radio science experiments.
The two days of talks are all lumped into the two videos below, and a list of all the talks presented can be found on the TAPR schedule website.
Just a few days prior to the 2020 GNU Radio conference, ARRL and TAPR will hold their yearly Digital Communications Conference (DCC) online. DCC is a yearly conference with many SDR and RF related talks, with a focus on ham radio science. The talks will be live streamed on YouTube for free, however you can register for $30. Registration will grant you the ability to ask questions or chat via Zoom, and includes access to the papers. The YouTube live link has not been provided yet, so keep an eye on the DCC web page for the announcement.
The review initially focuses on the differences between the RSP1 and the RSP2 units, explaining how most differences occur in the front end circuitry. WB8IMY then goes on to review SDRuno, the official software package of SDRplay units. The review is fairly brief, but the most interesting part is the lab test results which are displayed throughout the review.
WB8IMY performed several benchmark lab measurements such as frequency coverage, MDS (minimum discernible signal) levels (note MDS measured at 400 Hz instead of the standard 500 Hz for some reason), noise figure, AM and FM sensitivity, blocking gain compression dynamic range, two tone IMD tests, second order intercept points, FM adjacent channel selectivity and more. The results can be useful for comparing against other SDRs.
