I realize that the SDR1000 is a totally different animal as far as it
having an external Sound-card but with a Edirol Fa-66 you could get Jack
in linux to run the radio. I've got my Flex-5000 connected to the same
PC and ffado in linux recognized that it had the Flex5000 connected via
firewire but there was no mixer avail so i never got it working with
Jack. That was a couple of years ago so maybe Linux, ffado and Jack
might still be something to look into. It would require a linux driver
for the Dice chip in the Flex-5000. do the 3000 and 5000 use the same
Dice chip? I think that is probably the current stumbling block. it
wasn't so much the change to version 2 PowerSDR. I don't know who owns
the software the Dice uses, Flexradio or TC Technologies or, if they
could be persuaded to release the required driver bit's but I got
curious about it after finding this PDF with Google. A SOFTWARE-DEFINED
RADIO IONOSPHERIC CHIRPSOUNDER FOR HF PROPAGATION
<http://www.eng.buffalo.edu/wnesl/papers/SDR_chirpsounder_nordic_hf_10.pdf>
. In which they seemed to be using the Flex-5000 without going through
PowerSDR If it can be done once couldn't that approach be used to get a
Linux version written? I don't have the skills but somebody must. Read
that PDF I linked, I looks like it's already been done.

If I remember correctly? If you choose a earlier version of the
PowerSDR source can't you get to,some source that might enable you to
write a Linux or Mac version that can use the Flex-3000 hardware?
Version 1.18.6 could run the 3000 couldn't it? I thought the framework
changes began after we moved to the 2 versions based on Pretty Betty.
I know the SDR-1000 can run under Linux. Maybe it would only require
rolling back to earlier source.

The answer might be that using PowerSDR we are all forced to install
M$'s (.NET) framework, this is a messy way of programming.
Also I have never been lucky enough to get it to install under linux
regard less of flavor, I longed for a release that could be cross
complied but it was never going to happen, they did promise it, a
very long time ago, and then they changed the software they use to
write the software under, at that time I would say was the 'Turing'
point, it is a real pity as linux offers so much more that windows
ever would (also the Apple guys).
This would be the reason why I had to buy another computer and set it
up only for the Flex 5000a VHF/UHF, the other fact is they will go
out of their way to blame a computer, or the firewire card, or the
memory, even the software OS. Every thing that was put into my box
was first questioned to people in FlexRadio Systems now they blame
the TI chipset PCI-e card. The whole system running flat out never
goes over 25% CPU and 2 GIG memory out of the 8GIG installed this is
the highest speed memory the board can use, even has those gamer
heatsinks on it, The fact is this is the second fastest machine I own
just, the main server is only 400MHz faster dual core.
cheers for now

Thanks Dave!
I may need to ask my question more precisely though.
Suppose I want to take the published PowerSDR source, use it to
understand how PowerSDR interacts with the Flex hardware, and then
write a completely separate program to use with my Flex instead of
PowerSDR - i.e, something written to run on a Mac under OS/X, or
on a Ubuntu Linux system, or on Android, rather than on Windows.
Is that possible? Or is there some other missing critical
component, outside of the PowerSDR source, that makes such a
project impractical.
I can imagine, for example, that there might be closed-source
components like maybe a Firewire driver that only comes in binary
form for Windows, and would therefore be difficult to provide for
another OS environment without knowing exactly how it interacts
over the Firewire.
I'm wondering if, when I declare my Flex-3000 to be obsolete, it
has value as a sandbox for playing around with some software
ideas. Or should I get rid of it and buy one of the
experimenter-friendly SDRs out there.
