Hi Kaz, A very detailed performance comparison between the SDR-IQ and Perseus was made by Marco Bruno IK1ODO last year. His article "Digital Down Conversion Receivers Compared" was published in the March 2008 edition of RadCom magazine. It focuses on the hardware side of the receiver and strong signal handling performance. You can download the PDF here: http://www.ssb.de/amateur/pdf/radcom_mar08.pdf
Here are some key figures from Bruno's measurements: Blocking dynamic range, 2.4kHz BW: Perseus = 120db; SDR-IQ = 108db Calculated IP3 intermodulation distortion: Perseus = 33dBm (dither on, preamp off); SDR-IQ = 14dBm (max gain) IMD3 dynamic range: Perseus = 102dB (dither on, preamp off); SDR-IQ = 90dB (max gain) 73, Guy Atkins Puyallup, WA www.perseus-sdr.blogspot.com > Message: 4 > Date: Sat, 16 May 2009 09:35:03 -0500 > From: "Neil Kazaross" <[email protected]> > To: "Mailing list for the International Radio Club of America" > <[email protected]> > Subject: Re: [IRCA] SDR > Message-ID: <002601c9d633$805881d0$3200a...@bigyam> > Content-Type: text/plain; format=flowed; charset="iso-8859-1"; > reply-type=original > > Craig, I believe it was Bruce Conti who said his SDR was also significantly > better than the R8B for audio recovery from splits.
