Hi Wolf, Marco, LF,
Marco below cited some "classic" receivers (Racal 1792, Eddystone 1650,
Rohde&Schwarz EK081...and I imagine some Watkins-Johnson's could join the
group) and Perseus. Despite of the fact that all of these are some dB's
higher than my budget, I'm interested in your opinion about how best SDR's
compare with "classics"...Probably I'm wrong, but I believed that top-rated
radio's like Racal, Eddystone, R&S, W-J, etc. distinghished over the others
because of their superior construction, even from a mechanical point of view
(no wide-band circuits, lots of metal screens, etc.). How is this level of
quality achieved in modern SDR's?
Cheers
D.

Beware, the Perseus doesn't work at a few kHz; it's nice for LF (where I
use it too), but not for the lower VLF range.
The reason is, I guess, the input filter which has an "L" between the
input and ground (unlike SDR-IQ) .
Cheers,
Wolf .

I agree... probably a better choice, if you already have a _decent_ HF
receiver.
If not... consider buying a Perseus, but the price is 4,4 dB higher
than your target :-)
Otherwise, Racal 1792, Eddystone 1650, Rohde&Schwarz EK081, all in the
500-1500 Euro range.
I don't consider amteur radio receivers to be good radios, expecially
at LF.
