In the latest (October 2018) edition of The Spectrum Monitor, Thomas Witherspoon’s SDR Report Part 3 praises the RSPduo  where he writes ” The RSPduo is a true bargain for a feature-packed 14-bit, high-performance device.”

Later on in the same edition, Kevin O’Hern Carey WB2QMY features the RSP1A in “Step 1” of his new step by step guide to SDR  –  he goes through the purchasing experience and getting the software installed – next month he will feature its operation on air.
