Re: [Flexradio] Windows 8
:-) Well, thanks. I suspect Ubuntu may no longer be the distro of choice. Fedora would be, these days, probably. I couldn't say for sure, having been working mostly on OS X for a few years now. Were some team to develop a Linux-based app for the Flex products, they'd likely be best off just putting together their *own* distro based on, say, Fedora. It could run off a live CD or USB stick just fine.

Re: [Flexradio] Disk Jockey User Interface
Can you say 'MIDI'? It was designed exactly to capture fairly complex gestural information from multiple sources, in quasi-parallel. There are skillions of control surfaces that will emit programmable sequences of MIDI messages. Every OS one might care about already has capabilities for receiving and sending MIDI data, with time-stamping. It doesn't need to be USB2 as the 12Mbps speed of USB 1.1 is more than enough for how fast a human can move knobs. 73 Frank AB2KT -- Pourtant, j'étais fort mauvais poète.

A full-blown Cognitive Radio might be better thought of as primarily an autonomous agent -- a particular chunk of software -- that happens to have RF transducers attached to it. The radio capabilities extend far beyond merely reconfiguring the transducers and protocols, which is all that's implied by the conventional name. In particular, a full-up C/SDR is also capable of, say, defining for itself completely innovative sequences of actions based on, not just the signal environment, but also on the payloads of selected signals which are identified by probability models of unconnected systems, etc. Think of a smart contesting SDR.

Suppose what the technology does is make all the bands a panoramic playing board where you can see and track, moment by moment, everything that your competition is doing?

There's no FCC edict against reading the code which implements the lockout, however. And since no documentation is exhaustive, there are often details that can only be gleaned from examining the source. It's an important goal to minimize how much of that is necessary, however. In short, to cut back the necessary code-reading to stepping on bugs or resolving ambiguities in the spec. There is no substitute for having the source when you need it. As a system develops, the hope is that you need it less and less. There seems to be a little residual confusion still, though. The idea is *never* to keep details secret. The idea is to set up the rules whereby an application developer can draw a circle around what he or she needs to be concerned with in developing the application.

Of course you are very likely to find yourself in a vacuum -- which may be the intent and may, in fact, be the most efficient way of proceeding. Actually writing and debugging code is a fairly hermetic activity. However... OTOH you have to be really, really good to not want to see the outside ideas. Granted 90% of everything you get will be of little or no use (including what you get from me) but that last 10% (1%? 0.1%?) might prove surprisingly insightful and valuable. You have to dig through a lot of rock to find the occasional jewel. You find more jewels if more people are digging... I think the issue here is *not* a resistance to outside ideas. The problem is that so much of the design and implementation that's happening behind the scenes is essentially a refinement and a critique of a large body of closely-related work that's already very mature and very refined. Astonishingly little of the new architecture is in fact new at all. A lot of the design job has amounted to reviewing and culling the best available common, Open technology for our general family of applications. For example, much of the VR is different in no important details from a modern high-performance, mission-critical musical sound engineering application. The art and science of such applications is *very* ripe, and the documentary trail is decades long. Similarly, Erlang is the culmination of both a couple generations' worth of system development combined with shrewd predictions concerning the coming round of application-level networking innovations. It strikes me as the height of profligacy to think we can do better, given the resources available to us, at least as a practical matter. Designing this particular VR, for the application arena we're concerned with, requires above all a lot of woodshedding and absorption of all the pertinent preceding work. We've tried pretty hard to publicize what the necessary background is and how it can be acquired. Many of the issues that keep coming up for discussion are old, old discussions that have already seen their outcomes decided by the real world. One of the most conspicuous lessons is where the boundaries need to be drawn to keep a system coherent and maintainable. If I in particular am resistant to public discussion of many design concepts, it's because in any practical sense there *aren't* any issues to discuss. At least -- and I stress this, again and again -- at least, *not without a tangible prototype to criticize.* We're standing on the shoulders of many, many, very smart and productive developers and users *already*. Where we're at now is in exploiting what's already there. Once there's something to criticize, then it's time to bring out the knives and axes and see what we need to learn to do it better. Until then, the discussion amounts to little more than psychotherapy sessions devoted to how our (technical) ancestors decided to bring us up as children.

The midi message level seems fraught with peril, since it has to play nice with the midi messages between PowerSDR and F5K. Let's go through this again, slowly. Regardless of the fact that -- at present -- the F5K MIDI ports are visible from Windows, in principle and in the future the *only* exposure of the F5K internals is through a set of virtual resources that are not yet available to the public, as of July 2008. There will be MIDI ports available for using MIDI as a control channel for the virtual devices, but those talk to a proxy that implements a model of the device. In some small number of cases that proxy consists basically of a tunnel to some F5K firmware. In the overwhelming majority of cases, however, all that any application will know about is one or more virtual F5Ks. The real F5Ks are firewalled off from applications. There's no guarantee that MIDI control bears any consistent relationship to the MIDI messaging protocol between the VR and the firmware. The essential concept to get down is that, from the standpoint of any application, the entire system is distributed, and the actual locations of individual system components are unknown to clients. Regarding the host OS, that's an issue for a client. The VR doesn't *have* an OS, properly speaking, anymore than a webserver has an OS as far as its clients are concerned. 73 Frank AB2KT -- Travelling by airplane in the US is nothing more than mass training of Americans to the requirements of the coming police state.

The CAT system is intended precisely to handle legacy software, so it's the right thing to be using in these situations. That will continue to be the case.

That's questionable. The midi messages are basically like a stream of bytes going to/from a serial port. The messages themselves are 10 bytes each. To allow another writer to the port would mean that you would have to synchronize who was sending when. Having said all of that, there is nothing that would technically keep this from working as long as you avoid the collisions. In RX mode, unless you are changing frequency or setting some function, I don't believe there is anything active going on. So in RX, this should be pretty easy. I was wondering if the Windows MM driver would essentially queue the outbound messages. (probably not, see below) So PowerSDR is sending messages. Simultaneously, say you have something like a rotator control that is sending messages, destined for the I2C output. Presumably, the state machine in the F5K receives the entire midi sysex, parses it, then fires it off to do whatever, then goes back to fetch the next MIDI message.. So the messages are interleaved according to time of arrival at the Windows Midi outbound queue. Indeed, if one did the query messages, I could see things getting confused. The F5K would send the SysEx back, and it's not clear who the recipient task would be. But, if the Windows MM driver can only talk to one task at a time, (i.e. it's like opening a serial port), then this is moot. That is, if when you call Midi.MidiOutOpen, it only allows one user. (without delving too deeply into the arcana of the Windows MultiMedia API... http://msdn.microsoft.com/en-us/library/ms789663.aspx Fascinating that they handle MIDI as an audio device...

The way this problem is addressed under Linux is by using the so-called rt version of the kernel, and running the audio subsystem at a higher priority than typical user processes, even though it's running mostly in user space. One reason this is possible is that the window system and many critical system functions also run in user space, even though they might be essentially owned by the system rather than any individual user. The consequence is that, even with a monolithic kernel, routine but high-priority system operations spend a minimal amount of time hogging the kernel. What seems to matter most is the order in which tasks at the same high-priority level are scheduled for service. As long as the audio subsystem gets scheduled often and gets a chance to do its little bit of work ahead of things like paging, journal updates, etc., the audio hums along happily. In any case, the problem doesn't come up in the Linux world at all, at this point.

Re: [Flexradio] digital modes
On Thu, Jul 3, 2008 at 10:43 AM, Brian Lloyd [EMAIL PROTECTED] wrote: Once you have the signal in the digital domain it makes NO sense to convert back to analog. Except when there's no alternative ;-) Some of the modes will suffer worse than others. One thing to keep in mind is that many of the soundcard digital programs are built around voice-channel bandwidth and common consumer-grade soundcards. You have to resample the...ahem...high-quality SDR audio anyhow. Even a weak-signal program like WSJT is doing some serious mangling to the signal in software on the radio side of the software codec. As it is right now, almost no common digimode program is really set up to take advantage of what all-SDR can provide. The digital paths are there for convenience, mostly, not performance. In the first case, a third party program called VAC is used to create a virtual audio cable (VAC) between PowerSDR and the digital mode sound card program. In this configuration the AF between the two programs is kept entirely in the digital domain eliminating any noise or distortion introduced in the multiple A/D and D/A conversions. That sounds like the right answer. Under Linux and OS X this is easy since the modern audio subsystems are designed with full-duplex patching among audio apps in mind. However, it *does* make some sense ultimately to put codecs into the SDR DSP, for a variety of reasons. But this transposes the problem to a different area. On the application side of the codecs, the data will be bits, not samples. What's the transport yoga for these bits? If they represent varicode, where does the corresponding binary codec live? Furthermore they could be soft and not hard bits. Is the idea to put every variety of Viterbi decoder into the SDR? If not, what's the protocol? None of these questions has even begun to be asked yet, much less addressed, and it's lunacy to plunge ahead with a one-off solution based on our own idiosyncratic needs. It's a further safe bet that the existing digimode programs are far, far away from being restructured to handle binary data I/O rather than digitized audio, if indeed they can be restructured at all. Very few of the ones we've been able to examine at the source level (far too few of them BTW, since so many of the authors lock up the source) are designed for the kind of concurrency that would make that job palatable. Also BTW, these are exactly the issues that arise in building a systematic solution for digital voice, but in spades, since in that arena it will be almost essential to have a fairly tight feedback loop between the codecs and the DSP, irrespective of what the audio payload might be. The current generation of digimode programs, by and large, isn't up to that job in particular. 73 Frank AB2KT -- Sapristi nabolis! -- Count Jim Moriarty ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/

I would be *much* happier if the WonderRadio folks would make *their own* PowerSDR/DttSP distro, as they are entitled to do, because it would represent a level of work at least beginning to approach what they've done in retooling three boards down into one. Then we could all learn from what they do. I wish, for example, that they would turn the project over to Ramakrishnan Muthukrishnan and say, Go, make this even better. He's as well- or better-equipped to do that job, as anyone I can think of. He has contributed materially to the Linux effort for years, and deserves a chance to have his ideas and talents embodied in a showcase product.

Lee -- Don't get me wrong. There's nothing here that we don't agree on completely. What I'm whining about is a somewhat different issue. To take just a few examples: -- I get email *all the time* from students in the Indian subcontinent, Southeast Asia, and elsewhere asking for information and guidance on using and modifying our software. It's luminously clear that there is a huge groundswell of interest in SDR software and hardware, and a real eagerness to get going, but very few resources. -- From discussing this and other subjects with Ramakrishnan, I have the clear impression that the amount of SDR work going on in India is in fact miniscule, outside of a few extremely secretive government projects. The WonderRadio *could* have a massive impact on the level of development activity, *especially on the software front*. -- Even a casual perusal of the gnuradio developers' reflector shows that, among the students outside the US and EU fortunate enough to get formal education in the field, the level of knowledge and sophistication is very high, but the avenues for expression are few and narrow. So what I'm complaining about is simply that WonderRadio is only half a project, and that dumping off the other half to that big package from the US is, to put it mildly, a good way to miss out on a huge pool of talent and expertise that's already there to be exploited in some way or other. *I personally* want to be able to take advantage of what they can do, and it's not like we have to wait a generation to cultivate the people who can do it. 73 Frank AB2KT On Wed, Jun 18, 2008 at 11:05 AM, Lee A Crocker [EMAIL PROTECTED] wrote: Frank The end game is not here yet.

I got into ham radio when I was 6 years old because my Grandpa gave me an old AC/DC radio that covered 160M. Shocked the hell out of myself hooking up 50ft of antenna wire. I heard a couple of kids from the local high school mobile-ing home after school on that radio, and I JUST HAD TO GET IN ON THE FUN. Listening to WLS was fun, but this was friggin magic, and I was friggin driven. 12 years later I would up at Purdue in the engineering program. No AC/DC? Who knows what my life would have held.

Kirb -- The target for a preliminary suite of programs is Dayton next year. What that means is, it will be possible to run either the FLEX-5000 or the SDR-1000 entirely with cross-platform code (including a separate console) in distributed form (for example, with the console running on one machine and the DSP on another) before the middle of May next year.

I set my sdr1k to the fastest buffers, and listen to my Icom 746 sending cw.. the relay closeson the 746.. it sends a dit, and the radio just starts to receive again before I can hear the signal in my srd. I cannot see how that lag problem will be overcome... It can't. The latency that's solved is entirely from the point of view of the operator, the lag between the end of a sidetone-sounding element and the resumption of received signal. Purely from the standpoint of QSK, that's the lag that counts. Where this can be minimized is in not emptying and refilling the buffers. With full duplex the buffers are kept full with causal signal, so the audio output sent to the user can be switched at the lowest latency in the system. So, all of the lags on signals arriving at the receiver will be consistent once they get to your antenna. But before the signals get to you, they will have been subjected to essentially random delays due to the different paths they take between their antennas and yours. So it's not like there aren't delays in signal arrival already, messing with your mind in familiar ways. Still, all of them, and your keying sidetone too, will be time-shifted by a *constant, miniscule* amount, and that's the key ingredient in smoothing the QSK. The CW ops at the great coastal maritime stations were dealing with transmitters located many miles from their operating positions, keyed with cascades of relays over phone lines, and with TX and RX antennas similarly located at separate sites. For that reason among others, I suspect that perfect QSK allows a lot more flexibility than we've been stipulating here. I further suspect that a lot of *perceived* perfection of QSK is actually an illusion sustained by other factors in the switching. 73 Frank AB2KT Frank Brickle wrote: On Wed, May 14, 2008 at 11:59 AM, Jerry Flanders [EMAIL PROTECTED] wrote: If I understand Frank correctly, we will not see what CW ops call QSK in PowerSDR/Windows.

Re: [Flexradio] CW QSK ability
Without getting into a long discussion -- the situation isn't really that complex, nor is it worth spending more than a few further moments on -- the problem is all in the audio subsystem. Between PowerSDR, PortAudio, VAC, and realtime user monitoring requirements, the fact that anything approaching QSK is even possible is a testament to the programmers who've hammered on the Windows SDR code over time. The problem isn't PowerSDR. It's the lack of integrated, rational support in Windows for the kinds of state transitions in the audio subsystem that a QSK application requires, especially when users demand that it also cooperate transparently with third-party applications over which PowerSDR has no control. That's really all I as an individual developer have to say on the subject. The current state of PowerSDR is a best-effort attempt to bring an existing application into line with a number of fundamentally incompatible operational requirements, given also the demand that the nest of applications run on a platform with ill-defined capabilities and competition for system resources, and with an uncertain roadmap for the dominant OS in the future. Speaking only for myself, I think this line of discussion has run its course of usefulness. Development effort is being focused on doing it right, not patching the current system, which is basically unfixable in a systematic and maintainable way. Batting numbers back and forth is amusing, but the problems aren't quantitative. The problems are all practical and empirical, and they're being addressed.

In so many ways, FlexRadio is the solution who's time has arrived... indeed, a multi processor implementation might be nice, however, it should be necessary. The existing implementation IS multithreaded (and has been since the beginning) I suspect that there are some idiosyncracies in the implementation that have bad interactions with some of Windows. The existing PowerSDR uses the pthreads package to provide a POSIX threads interface to Windows's multithreading environment. There may be some issues there. After all, there are existence proofs for Windows software that has very good real time response characteristics, running on a single processor. Games are the most notable one, but there's also data acquisition software (e.g. LabView) that does quite well at a millisecond scale timing. I suspect, though, that the dollars/labor invested in making first person shooter games and LabView play nice in the Windows environment is substantial. bear in mind, too, that having the multiple cores available doesn't mean that you automatically get better performance. The OS has to support farming the work out to the cores in a useful way, and you're still faced with a bunch of other bandwidth limits (e.g. memory bus, i/o device access).

A good place to start is with the Extended CAT code vocabulary designed and implemented by K5KDN.

There may be quite a few more logical pieces, implementing things like multiple receivers, etc. The Core component communicates with the Console component via the CAT command language on a messaging interface, whether comm emulation or some other. Provision is to be made for either streaming panadapter and meter info, or externally controlling a panadapter/meter window. CAT is one path. It's a protocol layer between an application and the Virtual Radio Kernel. With this breakout it is possible to clarify my earlier question, which has two parts: 1. What will be the development language of the Core DSP and radio control component? It is currently a mix of c and c#. Will this be remodeled? No, the DSP core is pure C, and has never been anything but. That is not likely to change until third quarter 2009. We're still evaluating what DttSP 3.0 will look like. 2. What will be the development language of the Console component. Although users may create their own, I assume there will be one official UI. What will the development language and environment be? It is currently c#. Will this be ported or rewritten in something else, perhaps java? For the time being the Windows version will almost certainly be a very close version of the current C# console, while the Linux/OSX/BSD version will be John's new creation in Java. Beyond that we're envisioning a completely new structure making heavy use of 3D compositing window managers. John has already made some forays into this territory with his Java console and Sun's MPK20 virtual collaboration space. I am suggesting that the search for development tools and environment has priority over implementation details, because the latter depends so intricately and completely on the former.

A few questions about HyperSDR: - Is this the long anticipated 'New Architecture'? Yes. - Will the radio and its functions be accessible via DLL libraries? No. Something simpler. A message-passing protocol that works locally or remotely in a transparent way. Participating processes can be written in pretty much any language you please, because it's all protocol-based, not API-centric. - Is there a Time-Line so the Tinkerers can clear their schedules? After Dayton. There's a pre-alpha batch of code which I promised for 15 Dec but got diverted from for unavoidable reasons. Sometime in the next few days, I think. The current PowerSDR needs to be polished up and shrink-wrapped as-is for Dayton anyway. - Any docs, wiki or blog to drool over? ;-) Tim put a presentation on the Flex website that is based on a talk I gave at DCC in Hartford this year.

Re: [Flexradio] So, the new PowerSDR is moving to Linux
No, no, no. Please stop trying to twist what's being said. Once again, in clear, plain, simple words: You will *not* have to install LInux to continue running PowerSDR. PowerSDR will continue to be supported under Windows as long as there's support from Microsoft for Windows. What *will* happen is this. Past a certain point, functionality of PowerSDR as currently constituted will not expand further. That PowerSDR will continue to be supported but it will not enjoy significant enhancements. Major enhancements will require different OS support. Nevertheless, thanks to virtualization, both the old (PowerSDR/Windows) and the new (the Virtual Radio system) will be able to coexist and interoperate on a single (multicore) machine. You are not up to date regarding efficiency of virtualization, either. What part of this are you having trouble understanding? On second thought, don't bother answering.

WSJT only operates at one rate (11.025 kHz) so there has to be some resampling taking place between PowerSDR and WSJT. That resampling is probably the real culprit.

Re: [Flexradio] Spam: Question about CAT/Console logic
Bob Tracy wrote: The code I'm playing with now runs a little differently, it interfaces directly with the radio API (whatever that turns out to be). I have been using an API of my own design for testing in lieu of anything concrete from the Flex guys. It probably will have to change given the use of MIDI (which I have not had a chance to investigate yet) in the latest software design. One of the things that's going to make this a little confusing at first is the nature of the spec. There is no single API in the usual sense. There's an excellent discussion of this in Joe Armstrong's thesis Making reliable distributed systems in the presence of software errors (http://www.sics.se/~joe/thesis/armstrong_thesis_2003.pdf). A typical configuration (in fact, exactly the one I'm working on now) is something like this: (1) A node -- either a pure erlang process, or an erlang node written in some other language, it doesn't matter -- is sitting idle waiting for a sequence of bytes to arrive. By convention it's accepting data formed as CAT commands. As far as the node is concerned, it's just reading from a file descriptor. It doesn't know or need to know whether that descriptor is attached to a device (serial port), a file, or a socket. In any case, the input to this node is through the standard OS filesystem. (2) A little chunk of data arrives at the node's doorstep. The node is then responsible for making sense of the CAT command according to *its own* internal model of the radio. In other words, it's this node that thinks of things like VFOs, bandswitches, and so on. (3) The node then sends one or more erlang messages to the VR-Kernel. These messages are requests to bring the DSP software and the RF hardware into a particular set of states. For example, a request can express something like: Please bring about the changes necessary to produce 6kHz-wide SAM-detected audio from an RF setting of 3.851MHz. The VR-Kernel isn't at all interested in ideas like VFO -- that's part of the radio model implied by the CAT vocabulary. (4) The VR-Kernel either carries out the request, or else throws an error (which is OK -- errors are acceptable and frequent responses). An error travels gracefully back to the node, which can decide on an alternate plan of action. (5) The CAT node goes back to waiting for input. In short, the CAT-receiver node is set up like filesystem-in - translate - erlang-message-to-kernel. Obviously there's a symmetric bidirectional path for commands that elicit responses. Note that the CAT-receiver node is only one of many possible requesters for service from the VR-Kernel, and since it's speaking erlang to the VR-Kernel, it also doesn't need to know where that Kernel is running, nor what software and hardware are on the other side of the Kernel. Thus also a graphical console can emit either CAT commands -- from a program like grig, for example -- or it could emit rigXML to a *different* translator node, or it could formulate requests directly to the VR-Kernel itself. One of the especially tasty consequences of this scenario is that the implementation can grow incrementally, since in the erlang world (as with RPC) multiple versions of each component can coexist without conflict. A small implementation of this idea can grow and be refined easily without committing to a full spec prematurely. 73 Frank AB2KT ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/

Bob Tracy wrote: The code I'm playing with now runs a little differently, it interfaces directly with the radio API (whatever that turns out to be). I have been using an API of my own design for testing in lieu of anything concrete from the Flex guys. It probably will have to change given the use of MIDI (which I have not had a chance to investigate yet) in the latest software design. BTW I'm very aware how unhappy some people can become in the absence of a big book where all the subroutine call parameters and data structure elements are laid out, page after page, in advance. That's an unfortunate habit of mind that needs badly to be surmounted in this environment. It's very important to get hold of the idea that in principle there is *no way* to enumerate the possible states in a system like this, even theoretically. (Yes, I know, that's equivalent to saying the VR-SDR is nondeterministic, and that's correct. That's because it can change over time *without being restarted*.) The fundamental notions in the whole VR-SDR system are, first, that you *don't call subroutines*, you read and write messages to ports; and second, *errors are not mistakes*, they're customary and expected parts of system functioning. A priori there is no difference between errors and innovative conditions. In practical terms, what this means is that writing system components is much simplified, because the *only* things a component needs to know are the kinds of messages they will accept and the kinds they can emit, using nothing more than elementary I/O. For most functions the range of possibilities is very, very small. 73 Frank AB2KT ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/

Jim Lux wrote: And presumably, those messages to the DSP software and RF hardware are defined somewhere? (if only implicitly in the fact that sender node and receiver node have consistent software that has common semantics, i.e. is Frequency in MHz or Hz, etc.) Of course. The significant point, however, is that many if not most of the radio functions don't need to know anything about those definitions. Would the VR kernel, for instance, have some mechanism for backward compatibility with old style messages? Yes. This is all covered in considerable detail in the OTP documentation. You have the same thing in much simpler form with RPC, for example. 73 Frank AB2KT ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/

Re: [Flexradio] 2OSR Anyone???
Once again, demonstrating the point that contesters are driving so many of the interesting SDR challenges... Duane - N9DG wrote: Has anyone else pondered the feasibility of running one session of PowerSDR on two separate computers with both being connected to a single 5000A HW box?? Most of what you're describing is not a big reach at all. What's novel about this scenario is the need to arbitrate commands and data input from more than one operator at a time. On its face, that would seem to be much more of a human protocol issue than a technical one. However it does imply three important requirements: first, command message streams from each UI need to be stateful; second, the command protocol needs to include priorities; and third, commands may need some sort of time tagging and scheduling. Very interesting. Important stuff to bring into the picture. Fortunately, not something either the UIs or the DSP need to know anything about. For the rest, this configuration isn't much different from running multiple UIs on one machine, except the control/focus issue is more clearly defined for a single user with several UI instances. In that case, commands can still be treated as atomic rather than stateful, and can be executed as they arrive rather than needing scheduling. Much, much simpler. I'm thinking that such concept could be useful in an Unlimited Multi Op contest category... 73 Frank AB2KT ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
