Also be aware that Blocking Dynamic Range (BDR) for the Perseus is
relatively poor, as is true for all current SDRs.  BDR is 99 dB at 2 kHz and
117 dB at 20 kHz versus 139 dB for both 2 and 20 kHz, per ARRL Product
Reviews.  If you have strong neighbors (either commercial or amateur
stations), the Perseus will need additional filtering to prevent strong
signals from overloading the front-end.
