Congratulations to Eric, for a very lucid
explanation of the terms currently being bandied about.
PersonallyI think splitting up the reflector

I personally am learning a lot, and starting to

I agree with Eric also. Do not split this resource up. I also do
not read some topics but certainly want to be aware of the

I think it's a matter of proportionality. Usually an
off topic post has a life span of a dozen messages or
less so who cares. If it becomes a hundred messages

messages who cares. You might institute a convention
of listing [OT] before you post

Let me put forth a couple of concerns we have about how to
best use the reflector and forum resources.
Due to the nature of a "software" radio, we will always be

Jim,
The SDR-1000 is sold as amateur radio equipment under Part 97 FCC rules.
The fact that is an intentional radiator for the amateur radio service
places it under Part 97 and NOT Part 15 rules. The SDR-1000 is not type
approved so it is NOT licensed for commercial use outside the amateur radio

First, I think the mailing list(s) are a huge improvement over the

forum and work my way through the postings. Forums are great
I posted this on January 23 but didn't receive any feedback. Possibly due to
harmonic interference from Eric's newborn. Congratulations Eric.
I wonder if it is possible to run a second, or more SDR 1000's from a single
computer?
Is it possible to have two or more radios plugged into the USB
Mike,
There is no technical reason that the SDR-1000 hardware cannot be used
alongside another SDR-1000. The big question is if the PowerSDR can
handle multiple instances running simultaneously. I know at one point
this was possible as I used to do side-by-side comparisons in this
fashion.

Mike,
I haven't done it, but you need two things as I see it, based on
running two copies of MixW, HRD, or N4PY talking to two different
transceivers. You need to designate two separate ways to talk to the
hardware, and the only way I know of to do this is to use two sound
cards and the
Hey guys, very intresting indeed. But if you used for instance an
additional parrallel port card. Could you not just set the port addresses
in each instance of PowerSDR...no USB confusion. That would take care of
the control. How would one install say two Delta 44 cards and make them
look
Yes, it should be possible to use two parallel ports without conflict. Our
production test stand at one time used one SDR-1000 as a signal generator
and another as the device under test. Both were controlled by the same
software in that case.
I think you would need to have two installations
I'm 100% with Mike on this one. It would be very useful to
run at least two instances of PowerSDR on 1 machine if
possible. With the level of CPU usage that I've seeing on
recent builds of PowerSDR on my AMD XP3000+ I think that
there is plenty of horsepower left to run a second PowerSDR
session.
Mike,

Eric and all, thanks for the comments. I think as discussed below, if your
ultimate setup is using two Delta44 cards...(as I would like to have) the
control panel handling two cards...I remember seeing that it could handle 4
devices. I guess one would not have to install the software again
I would suspect that the Delta1010 would work nicely, too. It uses a
single PCI card and an external, all-metal rackmount box with enough ports
for four SDRs (TX RX). In fact, the external box houses all of the A/D
D/A converters, so it's even quieter than the Delta44. It also appears
to use

is important that the rig be absolutely stable because a change of 10 to

It is also less subtle.

The SDR-1000 may require certification as a Part 15 Class B unintentional

that the new dual core processors have seperate 2MB cachesso all the

The P4 I run with the 2MB cache and the refresh of the pan adapter window
over 30 FPS only makes the unit sit around 15% cpu utilization.

The whole area of a SDR is one that is going to
require a lot of technical hand-holding for the
average ham, so you need to address this fact.
