Single-tuner 14-bit SDR covering 1 kHz-2 GHz with no gaps
Up to 10 MHz of visible spectrum
Three antenna inputs (two SMA + one BNC) with front-end filters
HDR (High Dynamic Range) mode below 2 MHz
0.5 ppm TCXO and external reference input
Free SDRuno/SDRconnect software
Strengths
Excellent 14-bit dynamic range; HDR mode superb on MW/LW; three switchable antenna ports; great value.
Weaknesses
Receive only; the original RSPdx is superseded by the RSPdx-R2; needs a PC/software.
Verdict
A superb wideband monitoring SDR - the RSPdx's 14-bit front end and HDR mode make it a standout for HF/MW DXing and broad spectrum work.
The SDRplay RSPdx is a single-tuner 14-bit SDR receiver covering 1 kHz-2 GHz with up to 10 MHz of visible spectrum, three switchable antenna inputs, a 0.5 ppm TCXO and a High Dynamic Range mode below 2 MHz for tough MW/LW work. It runs SDRplay's free SDRuno/SDRconnect.
Compare the entry SDRplay RSP1A; feed it from a discone for wideband monitoring.
