??? I don't know too much about all this, but I personally
have experienced noise generated from some of the clones I have built in the
past. Some of the cheaper Motherboards seem to have this problem. I am running
an ASUS MB at this time and have not noticed any noise problems problems, so
far. I hope I have similar results to yours, Jim.

I have my
softrock 40 running.? It's plugged into an external USB hub for
power,
and hooked up to my B & W broadband folded dipole.? I can find
no
birdies within it's limited tuning range - 7.030 to 7.080 as specified
in
the AMQRP info.? It is extremely sensitive, and copies signals
within that
range as well as my K2 does, and that's saying something.?
The K2 has by far
the best receiver of any rig I've ever owned.
All
this talk about computer birdies and pc noise is pretty much
unfounded.
There is NO noise apparent with the scope on the DC voltage line
coming from
the USB port.
The computer is a Dell Dimension 8100,
Pentium IV @ 1.4GHz and even with the
covers off, I still cannot find any
birds attributable to the computer.?
I AM using just the
bare-bones, unsupported SoundBlaster PCI sound card
that's built into the
Dell's motherboard.? It performs adequately for the
Soft Rock 40, but
I would presume to say that if one had an SDR-1000, this
card would
definitely be struggling.? My sampling rate is only 48 KHz, and
it
still does very well.?
Maybe this will allay some of the fears I
see expressed here on the
reflector.?
What the heck do you
expect for $23 bucks a full blown SDR-1000?? Jeez,
lighten up and
experiment with the thing! It works as advertised, and maybe
even better
considering the low end sound card I'm using.
