You are moving now from a superlative SDR-1000 to a much more modest
Perseus, the reason being that it can copy a huge 400 Khz of spectrum
at TOH for later playback, and however modest the specs of the Perseus
might be, this facility is going to get you lots more catches and
positive ID's.

Hi again John,

I would have to disagree that the Perseus is a "much more modest" receiver.
The SDR-IQ would fit that description, but Perseus has +31 dBm IP3 and 125
dBm blocking dynamic range (@ 14 MHz), assisted by a total of 9, 6-pole
bandpass filters and one 3-pole lowpass filter to help achieve this
performance. I know specs don't tell the whole story, but these are very
good to excellent numbers, not modest at all. In fact, the Perseus appears
to be roughly in the same league as the SDR-1000.


Wow!

I just looked at the Perseus, it looks incredible. I was thinking of
getting an SDR-IQ but since I'm in north London, UK, the extra DR of the
Perseus could be useful. However it's more than double the price and I
could pick up a preselector for under £100. So now I can't decide - and
the wife would go nuts if she ever found out I'd spent £600 on "just a
radio"!
