Nah. Scribed directly onto DECtape with magnetized needles.

Don't laugh, though. Did you ever see a description of how the RCA
Mark II Synthesizer had to be programmed? It tells you something
that people abandoned it and went *back* to splicing 1/4" tape
with razor blades.

Re: [Flexradio] Problem with adapter USB

[Terry Fox]

I'm not sure this will help at all or not, but Microsoft has a utility
called USBVIEW that shows a lot of the USB parameters.  I have used it with
DLP Designs USB modules to help me identify if a device has enumerated(?)
properly.  It shows whaich hub devices are connected to, their names, IDs.
etc.

I think I downloaded it from either the DLP Design or FTDI website, I could
not trace back where I got it from exactly.  It is copyrighted by Microsoft.

Thanks for the information.  More and more it is looking like a

Re: [Flexradio] Price Increase and 1 watt SDR discontinued

It's simply a business decision. Our cost to build the radio has increased
substantially.

We  will continue to support all models well into the future.

Why?  Is it that big a deal to build a SDR-1000 without the 100W amp, heck 
its built modularly anyway.  Some VHFers with transverters dont want the 
amp, I know we are a small minority, but is there something else?  Does that

mean that the 1 watt SDRs may never get the forward power meter working in 
CW in a future PowerSDR version?

Re: [Flexradio] More Strange Frequency Drift Problem

[Maarten N1DZ]

The same drift you described I encountered once in my 2m transverter.
I had stabilized the transverter with a thermistor soldered to the crystal.
Everytime I transmitted the voltage would sag a little causing a  
temparature change that caused the oscilator to drift a little.
It would only occur in high duty modes. Ultimately I gave the thermistor  
its own power supply. After that the problem was solved.
Good luck and let us know if you are able to solve it.

Re: [Flexradio] Problem with adapter USB

[Greg]

Don't know if it will make a difference,  but I saw a new computer accessory
from Aerocool that has powered USB ports.  One for 12V and one for 5V.  Its
called Powerwatch II.

They're not that expensiveone version that takes up 2 5.5in bays is
about $65 and there is another that goes into a 3.5in bay that's less.

Re: [Flexradio] Price Increase and 1 watt SDR discontinued

[Mike King - KM0T]

Why?  Is it that big a deal to build a SDR-1000 without the 100W amp, heck 
its built modularly anyway.  Some VHFers with transverters dont want the 
amp, I know we are a small minority, but is there something else?  Does that 
mean that the 1 watt SDRs may never get the forward power meter working in 
CW in a future PowerSDR version?

I frequently use OO for my wife to "fix" Microsoft Office documents that get
wedged on account of M$Office bugs and version incompatibilities.

But really, if you use either OO or MO for anything beyond letters and short
articles, you deserve whatever misery you get. Real Men use TeX.

Works fine here in Linux using a tool called wine. It lets you use your

There are incompatibilities between MS Office 2000 and MS Office 2003 
both on the Windows platform, so you cannot really use this complaint

Hi Bob,
I ´ll try to describe what I see:

The window  selected is always Blkharris.
I inject a -30 dBm signal from my generator (worse than yours, but it 
doesn´t matter here) and proceed to calibrate.
I observe the calibration steps and I see how the procedure adjusts the 
level for each preamp setting.  The adjustment makes the graphical level 
to increase until it reach -30 dBm, both in the spectrum an in the 
figures below it, and then switches to the next preamp setting and 
proceeds in the same way. 
When the procedure ends every reading is coherent unless the polyphase 
was on.  In that case the spectrum jumps  3 dB up.
I doesn´t make any diference if the calibration is done with the 
polyphase switched on or off, because its effect happens just  after the 
calibration.  Once the calibration is done, everything agrees if the 
polyphase is off, and 3 dB high with the polyphase on.   The signal 
meter shows the right figures in either setting.
This is independent of the sampling rate and the number of buffers (this 
was not true prior svn 802).  In this release the problem appeared to be 
solved, but it happend again in svn 803.

I hope this can give you some clues.
73  and thank you for your efforts.

Ignacio, EB4APL

Re: [Flexradio] Linux third party software

[Frank Brickle]

John --

Reams of it. Please see

<http://radio.linux.org.au>

For logging, my favorites are

 * tlf for HF contesting, which is TR and CT compatible
 * roverlog for VHF contesting
 * xlog for general uses

All of these will do CW and voice keying, rig and rotor control,
cluster spotting, can be networked, etc. There are several others.

For digital text modes, some soundcard choices are

 * gMFSK, simply superb, provinding MFSK8/16, Olivia, Hell, RTTY,
PSK31 BPSK and QPSK, PSK63, MT63, and THROB1, 2, and 4. It is the
best-written amateur radio program I know. It also will do rig
control and interoperates with the various logging programs.
 * hfmodem, which will do RTTY, AMTOR, GTOR, and PACTOR I.
 * soundmodem, which will do VHF and HF packet
 * fldigi is a new program that looks promising
 * WSJT
 * and there are at least half a dozen other PSK/digital mode
programs readily available, including gpsk, kpsk, linpsk, twpsk,
and so on.

For SSTV,
 * qsstv, a functional equivalent to MMSSTV

AX25 packet, using either the soundcard or nearly every available
external TNC, is a standard part of the Linux kernel.

Using the jack audio subsystem, you have available a tremendous
range of plugin DSP facilities for EQ, filtering, echo and reverb
and pretty much every other common kind of outboard processing.

For recording and editing, there are
 * audacity
 * snd
 * ardour

Much antenna modeling software.

Etc. etc.

Re: [Flexradio] "S" Meter Lock Up

[Edwin Marzan]

This has happened to me as well. Usually happens when I switch to another 
program while running PowerSDR. So far, exiting PowerSDR and restarting has 
been my only solution. It has happened 2 times. I'm wondering if switching 
between programs has something to do with it.

Perhaps something to do with the screensaver?

Re: [Flexradio] Problem with adapter USB

[Ken N9VV]

Right Peter. Some inexpensive PCs use +/- 3vdc instead of +/- 5vdc for 
both the parallel and serial ports. Some manufacturers are abandoning 
the original specification when building inexpensive mother boards. [I 
had one of these in a Wal-Mart Celeron and it was a nightmare].

A PCI Parallel card or a PCI USB 2.0 card are not always the solution 
because some motherboards do not provide the required 5vdc. You can 
purchase a POWERED USB HUB that uses a wall plug in power cube to get 
the necessary 500ma and +/-5vdc power.

Good 13.8vdc for the rig, good powered USB HUB, and good grounds are all 
necessary for optimum SDR-1000 operation.

Re: [Flexradio] Problem with adapter USB

[petervn]

A good 2007 to all

 

I have an Flex USB-paralel adapter that worked intermittently

on one computer (a Shuttle without parallel port),

dint work with another computer (I think it was a laptop, not sure)

and finally worked on an Asus-espresso computer.

This Asus computer has a parallel port available that I use now.

 

When the USB adapter does not work it is seen by the computer 

as an "unknown device", when it works it is found as an USB device

with an identification (not have the adapter here, cant tell the id)

 

I still intend to test the USB adapter again with an external power 

supply, not done jet.

I think that the available USB power is one of the prime suspects 

in these cases. If I find something conclusive I let you know.

 

There seems to be a story that there are parallel ports with to low 

voltage levels for the SDR1000

yes.. but the OS platform those folks develop for determines the size 
of the pool of potential buyers of the SDR1000 hardware (and its 
successors).  Take an extreme example.  Say I developed a 
miraculously wonderful version of PowerSDR, but it runs ONLY on 
PDP-11 with an attached FPS coprocessor driving a Tektronix 4014 
graphics terminal.  Even the fact that it's written in C and 
opensourced wouldn't drive many sales of the SDR1000, because very, 
very few people have such a hardware configuration.  And, they 
wouldn't be likely to go out and get the hardware just to run my 
fabulous software (heck, they probably wouldn't take it if were offered free).

The same applies, but to a much less degree, to software that 
supports the SDR1000.  No matter how wonderful the Linux version, 
unless you can also do all the other stuff you do with Windows, and 
get it without suffering pain, most people won't switch over.  People 
like their existing word processor client, they like their email, 
they like their printer drivers, etc.  You'd have to give them a very 
convincing total package (not just PowerSDR) to get them to switch.

A "live CD" style scheme (like Knoppix) might work, especially if a 
way were provided to update the PowerSDR image. That is, you'd boot 
off your SDR1000 CD, and it would use the latest version of software 
stored on your hard disk (which you might have updated using an OS 
independent web browser interface).  Of course, if Windows moves to 
an encrypted disk structure, it would cause problems.  But, even 
then, you're basically converting your PC into a dedicated system 
while you're playing radio.  No cut and paste from an email or 
document into a PSK31 program, etc.  So, you've taken a powerful 
multitasking computer and turned it into a special purpose dedicated 
box.  Well, then, why not just embed a single purpose diskless PC 
into the radio.

I call BS.  It is a royal pain just to reinstall your existing 
applications on a new computer, staying in the Windows world.  There 
are lots and lots of Windows only applications out there that are 
quite useful, if not necessary.

For instance, I use 4NEC2 as a front end for NEC analysis.  It's not 
available for Linux, and I'm not particularly eager to go back to 
writing and reading bare NEC decks.

I use Microsoft Word's equation editor, reviewing, and cross 
referencing capabilities a lot, and open office is incompatible for 
some reason.  I haven't dug into why, but since I need to generate MS 
Word documents for others to review and work on, I'm not likely to 
change, nor am I interested in spending lots of time figuring out how 
to make it compatible.

What about hot-syncing my Treo with my PC?

What about support for my Tablet PC?  I'd hate to give up my stylus 
and the ability to take notes on a tablet.

Then, there's those horrible, but necessary, websites that are IE 
only.  All too many manufacturers of components put their data out 
with slick IE only web interfaces.  Why, I do not know (just 
ignorance on their part, or they hire a low budget web developer who

A fair statement.  However, my main point was that if the group were to do
something as sterile as moving from one language to another, the reasons
would presumably be more than simply a list of technical specifications.

Licensing provisions, under the right reality, might well be such a
reason, and Java now has some real advantages of just the sort that we'd
be looking for in such a world.  C might also fill the bill.  In any case,
it would be a short list, because it would have to run under Billyworld
and Linux and, possibly, OS X.

And, I have carefully noted that those that _are_ doing a substantial
fraction of the coding have also expressed concerns about the MS
environment, so it was appropos in that sense, at least.

Also, the SDR is a bit of an odd duck in that it (in a sense) "abuses" its
host operating system into performing real time function on an audio
stream.  Indeed, some of Bob's explanations show the amazing lengths that
are required to make this thing go here and there.

May we long continue undisturbed and unnoticed, but both of those things
are items that could go unexpectedly wrong in just the right set of wrong
choices made in Redmond for reasons having little to do with software
defined radios.

The recent discussions have simply exposed an issue that was always there
and will never quite go away.  We aren't in Dosland anymore, Toto.

This is pretty much the same conclusion that I keep coming
back to. Although I don't think that the SDR-1000's PC
necessarily need be embedded.

FWIW I drive my SDR-1000 (& other SDR experiments) dedicated
XP machine 90% of the time via VNC from my main 3 monitor W2K
 system even though the SDR-1000's PC is on the same KVM with
the W2K box.

Re: [Flexradio] v1.9.0 Level Calibration

Ignacio:

I am sorry you are having a problem with it.  I just put the code on my 
signal generator (8640B).   I tested every buffer size,  audio and dsp, 
with and without polyphase display.  The results were identical to the 
tenth dB on the meter and the same pixel on the display.   Are you using 
the Blkharris window?

Setup->DSP->Window == Blkharris

Then recalibrate.

Re: [Flexradio] Linux, any chance of a knoppix like setup?

[n4xwe]

Hello Everyone,

Over the past couple of days I have heard a number of comments in this thread 
about the "heartache" and "pain" associated with moving from Windows to the 
Linux OS.  

How soon we forget.  

The transition from DOS to the earlier versions of Windows was much more 
painful.  Not only did we have to deal with that buggy, crashing, piece of 
crap, Windows GUI, but the initial learning curve was tremendous. The only 
saving grace was that most (as in not all) of the Windows applications from the 
user perspective operated in a similar fashion.  And let us not forget about 
some of the horrific application software from the early 90's.  M$ Project 
comes to mind as one of the worst but there were plenty of others.

So when others talk about the "pain" and "heartache" associated with Linux, 
remember it is all relative.  In my opinion, the transition from Windows to 
Linux was a piece of cake.

73,

Dan N4XWE

Just tried svn 806 and the bug remains here.  The readings in the 
display, both graphically and numerically are 3 dB higher than the 
calibrated value, which is correctly shown in the signal lervel meter.

I don't believe Flex-radio sell the PowerSDR at all. It is open source 
and GPL. Flex-radio sell the Flexradio HARDWARE, and use PowerSDR as a 
tool to do that. The better PowerSDR is, the more Flexradio HARDWARE 
they will sell. They let other people in the open source community 
improve the software with them and that results in better, more reliable 
software, and therefore more Flexradio hardware sales.

I don't believe there is significant pain to shift from Windows to

90% of calls I have fielded with this kind of problem relate to installing
the driver properly.  Let me describe the procedure (and we will get this
into the kb if it isn't already there):

1. Download and install the USBIO software from the knowledge.
2. Plug in the USB Adapter.  If you had already plugged it in before, you
may have to go to the Device Manager to update the driver for #3.
3. When prompted, select the C:\Program Files\FlexRadio Systems\USBIO
directory and the driver should install.
4. Start PowerSDR and check the USB Adapter checkbox on the Setup Form ->
General Tab.

If you continue to get an error, then either the driver is still not
installed properly or the device has failed.  Contact us in either case so
we can help you get things straightened out.

Re: [Flexradio] D anyone?

[Eric Wachsmann]

For the record, I actually am a fan of Java.  However, I am NOT a fan of
developing a Java GUI (having done this in the past).  I'm sure the tools
have improved over the last few years since I last worked with a Java GUI,
but back then it was about as easy as Visual C++ GUIs before Windows Forms
(choke...gag).

Personally, I would love to use a GUI development language/tool that was not
wrapped up in the Microsoft hoopla, but there is just no denying that the
Visual Studio IDE + Windows Forms makes GUI development nice.  Nicer than
anything else I've used to date.  Intellisense, break points with watches,
immediate function calls while debugging, etc are really hard to live
without once you have had them.  The downside (besides it being Microsoft
and thus tied to the hoopla) is the massive amount of auto-generated code to
build the forms.  They addressed this partially by using another separate
file for the auto-generated stuff in VS2005, but it is still excessive in my
mind.

I suspect that other tools will (or have already) surpassed Visual Studio in
these terms (GUI development), but I have yet to use one.  Eclipse is still
on my list of downloaded, but not yet tried tools.

Let me get your argument straight.  Java is "bad" because of its huge
library, but C#, which has 35 to 50 million lines of code of Microsoft
APIs behind it is. . .good?

Java, with a few fits and starts, is well on its way to being open
sourced.  Perhaps for that reason alone its worth another, fresh look.  We
just had a cow thanks to some hiccup (yet to be fully proved) from Vista.

If Java really fulfills its newly minted promise to do real GPL, we'll
have something C# will never seriously give us.  Which is, a product that
can never be changed adversely or withdrawn altogether.

And, in any case, as far as I can tell, the performance sensitive code is
going to stay in C regardless, so this is all about the presentation code
anyway, isn't it?  That runs at human speed.



Larry  WO0Z

PS, if you're going to argue we can subset C#, that argument applies
equally well to Java.  But, the main arguments at this stage may not be
technical.

Sure. BUT PowerSDR is a product from a company that presumably wishes 
to stay in business and has to sell product to do so (unless Gerald 
is going to altruistically support ham radio into the future..).  And 
for the next few years at least (and probably well into the next 
decade) the dominant platform (in terms of percentage of computers) 
is going to be windows (just out of inertia, and because MS can spend 
a gargantuan sum of money to keep it that way).  Out of the 
hundreds,if not thousands, of SDR1000 owners, I suspect a very small 
percentage participate on this list, and there are a huge number of 
people just appreciating the SDR1000/PowerSDR combination as a high 
performance "black box appliance".  And, statistically, those people 
are more likely to be running Windows.

The vocal minority, interested in tinkering, etc., for whom open 
source is a godsend, probably has a higher percentage of Linux 
users.  Further, just because they're willing to tinker, they're also 
willing to suffer some amount of pain to shift from Windows to 
Linux  (and, yes, there is significant pain in doing so, 
notwithstanding how congenial the environment is after the changeover).

I actually think the optimum long range solution is a Linux embedded 
PC in the radio box talking over ethernet to the UI running on 
Windows (or whatever).  Then, the radio hackers get a nice open 
source platform to tinker in (and it's easier to do that kind of 
thing in Linux than Windows).  The "all I want is a radio" folks get 
what they want, without having to buy a whole 'nother computer that 
then has to be managed. (the embedded Linux box is a stripped down 
distro, etc.)  And the Windows UI folks get to do all the nice 
Windows UI things, including coexisting with other ham radio and 
other software.

Yes. And that IS a benefit of opensource.  The point I was trying to 
make is that we already accept some limitations on what we can do to 
meet regulatory requirements, and it's not much different for digital 
rights management.  It might well be that you can't run PowerSDR 
(which would need fully open interfaces to adhere to the philosophy) 
and watch a DVD or listen to iTunes at the same time.  Sure, it's not 
the "total flexibility do whatever I want in a single box nirvana," 
but that's never going to happen anyway, right?

Splitting the DSP and "radio" functionality into a separate processor 
(running Linux or RTEMS or whatever) and just passing control 
interface and audio through Windows fits within the existing and 
planned DRM models of Microsoft just fine. It's just another audio 
stream, and it can be tagged as wideopen unprotected, etc., without 
any trouble.

What you will find is that Windows is going to be ever less of a 
"hackers platform" than ever, but that's no big surprise.  It has 
always been painful to try and do real-time processing within 
Windows, because, when it gets right down to it, Windows is more of a 
"Presentation Manager" than a real operating system, and so, very UI 
centric, not OS services centric.  And, as corporate customers demand 
real OS features (like privilege management, security, etc.) it's 
only going to get less tinkering friendly.  With security (in any 
form) comes finer grained access controls and a larger administrative 
overhead to manage those controls.  It matters not whether you are 
protecting some video stream or sensitive health care information, 
the trend is to better security overall.

Actually it's not easy, Java has a huge learning curve due to it's 
massive libraries. So you would be placing considerable limits on who 
could help. And even more important the major player "programmers" are 
not fans of Java, and it's important to keep them happy.

The current choice C# is not a bad choice, better than Java or C++.

However if you use DttSP to do the math for you, you are free to use 
whatever else you like for the display/control program, there are some 
consoles written in Java, Squeak (smalltalk) and, C# at the present 
time. This situation keeps getting better as more and more separation 
between the modules get implemented.

The plan is for eventually to have a message driven interface between 
the modules driven by Erlang messaging, which will make it very easy to 
write a control/display program that basically sends messages to another 
module that could be on another PC or locally. When they get there I 
anticipate a free for all with people writing their own consoles in 
every sort of language and platform. Erlang has libraries for all sorts 
of languages and OS's to send/receive messages.

It will be really exciting once some of this gets implemented.

Re: [Flexradio] 10 kHz AM filter off center

[Eric Wachsmann]

This capability was added in this last round of updates and allows the user
to completely customize the filter settings by mode to whatever they would
like it to be.  You want a 20kHz filter on AM, you can do it.  A 175Hz
filter on CW, no problem.  

This was the universal solution for the issue of choosing a set of 10
default filters with which everyone was happy.

Eric,

Thanks for your hint which fixed the problem. I was not aware that you can

* High Performance Software Defined Radio Discussion List *

Versions of the compiler are available for Linux as well as Win32. 
They say the difference is "String literals are read-only. Attempting 
to write to them will cause a segment violation" with the Linux 
version. Is this a serious limitation for PowerSDR?

Sure would be nice if one development effort could be easily compiled 
to both platforms. Otherwise, recent postings here make me wonder if 
a "consumer" version of PowerSDR will still be available in 3-4 years.

Re: [Flexradio] Using the signal generator to set levels

[Eric Wachsmann]

Using the signal generator is an excellent way to set transmit levels.  Note
that you also need to calibrate your microphone input.  Ensure that you are
hitting 0dB on peaks for the best signal to noise ratio possible.

Re: [Flexradio] Problem with adapter USB

[Eric Wachsmann]

90% of calls I have fielded with this kind of problem relate to installing
the driver properly.  Let me describe the procedure (and we will get this
into the kb if it isn't already there):

1. Download and install the USBIO software from the knowledge.
2. Plug in the USB Adapter.  If you had already plugged it in before, you
may have to go to the Device Manager to update the driver for #3.
3. When prompted, select the C:\Program Files\FlexRadio Systems\USBIO
directory and the driver should install.
4. Start PowerSDR and check the USB Adapter checkbox on the Setup Form ->
General Tab.

If you continue to get an error, then either the driver is still not
installed properly or the device has failed.  Contact us in either case so
we can help you get things straightened out.

Re: [Flexradio] D anyone?

[Jerry Flanders]

Versions of the compiler are available for Linux as well as Win32. 
They say the difference is "String literals are read-only. Attempting 
to write to them will cause a segment violation" with the Linux 
version. Is this a serious limitation for PowerSDR?

Sure would be nice if one development effort could be easily compiled 
to both platforms. Otherwise, recent postings here make me wonder if 
a "consumer" version of PowerSDR will still be available in 3-4 years.

I think the answer is both. It works very nicely as a consumer radio, 
but also is open enough to act as a hacker platform.

"must" is way to strong here. PowerSDR does not have to go any 
particular route. It is an open platform and will just go whichever way 
users want it to go.

Regulations are different in each country. The PowerSDR source code 
ships to be compatible with US Regulations, but users in other countries 
are free to modify the source code they use in any way they see fit and 
lawful. For example, the UK authority is not nearly as draconian as the FCC.

The SDR1000 is most certainly not a "no user serviceable parts inside" 
product.

[Flexradio] 10 kHz AM filter off center

[Willi Reppel]

Hello all,

I noticed that in version 1.8. the center frequency of the AM filter setting 
for 10 kHz is off center. The USB brickwall extends to +5600 kHz while the 
lower one ends at -4440 kHz, ie. the width is 10 kHz but off center.
I tried the older version 1.6.3 and here the 10 kHz AM filter is symmetrical.
Can anybody confirm this or is it a senior moment on my side?

There is some interesting commentary that follows that article, to 
wit, that to a certain extent, the concerns are overblown and 
theoretical.  Yes, Microsoft *could* cause everything to quit working 
and yes, there could be unforseen side effects from DRM.  However, 
this is the same thing that happens now.  Most MS users use automatic 
update, and nothing stops MS from rolling out (either by accident or 
design) a patch that kills Windows. (e.g. the whole WGA thing).

Corporate users would obviously not tolerate such a threat to mission 
critical systems (and, in fact, such a "remote software kill" feature 
if implemented intentionally is actually illegal (civil not criminal) 
in some case), and since MS wants corporate users, I suspect there 
will be appropriate procedures (and, most likely, Vista Corporate 
Edition) to deal with it. Tying software serial number to physical 
hardware has been around for decades (remember "vault" and 5 1/4" 
floppies) and doesn't create a significant hardship on the mainstream 
corporate computer builder/user nor on the run of the mill consumer, 
who is buying a "computer as a black box".


Most consumer electronics is not "user serviceable" in any real sense 
of the word (and neither are most ham radios, for that 
matter).  Nobody, when faced with a dead $40 consumer DVD player, 
goes out and buys a replacement drive and tries to bolt it into the 
existing chassis.  Likewise, the TIVO box, the Sony Playstation, etc. 
(not to say that people haven't done it, it's just not the intended 
use case.) For that matter, the same applies to TVs and Stereos. PCs 
are EXACTLY the same.  They are pieces of consumer electronics and 
have long since moved away from the "open up the case and swap in 
another interface" world.  (hence the popularity of 1394 and USB 
interfaces).  Sure, there are places that do servicing (for all 
appliances) and for decades there has been a system (authorized 
factory service centers, SAMS Photo-facts, etc.) to deal with 
repair/replacement at the component level.

The fact that this "no user serviceable parts inside" philosophy 
happens to be tied to digital rights management does cause a lot of 
"information wants to be free" philosophers to get their knickers in 
a twist, but, again, this sort of thing is nothing new.  The attempt 
to control the hardware and software configuration has great 
potential benefits for most consumers (at least as far as the user 
experience goes.. note that Apple stayed in business many years with 
a very closed architecture) and is legally required in some cases 
(the reason there are no firmware updates (and not even any mechanism 
for doing so) for my IC7000 is that the FCC requires "no user 
serviceable" components to get equipment authorization.. not because 
Icom has some evil plan for world domination)

The people who will be most subject to the problem will be the ones 
trying to do something unusual (i.e., the hackers and tweakers) or 
who are trying to reuse old hardware (replacing the mobo, for 
instance).  But this is nothing new, and is just part of the fun of 
hacking.  It just means it gets a bit harder, or you have to choose a 
different platform to hack on.


And that gets to what the future of an SDR1000/PowerSDR is...

is an SDR1000 a hacker platform?
is it a consumer software radio?

If the latter, then PowerSDR must go the Vista route (unless MS goes 
out of business or becomes a <10% minority share player in the 
market). There are already limitations imposed on PowerSDR (as 
shipped) to meet regulatory requirements, and any peculiar DRM 
related functional issues would be the same. Hey, the source code can 
still be open and so can the hardware interface specifications, so 
the philosophical intent of Gerald, et al, can still be met.

As far as the former goes, there's a small and vibrant community of 
people playing with the SDR1000 hardware platform in a variety of 
ways. And I think it will stay that way.  But recognize that the 
software/hardware hacker and tinkerer is a distinct minority of the 
total SDR1000/PowerSDR market.  There are a lot of people who would 
be perfectly happy with a SDR1000 in a sealed ("no user serviceable 
parts inside") box connected to a sealed Windows Genuine Advantage 
("No user serviceable software inside") Vista box, as long as the box works.

I've been running this same free VMware server under Kubuntu -- running

VMware doesn't yet support firewire.
