Aside from the considerable difficulty integrating such a thing with the current PowerSDR software, it's an intriguing concept. The bandwidth of the new radio is sufficiently large that you could probably cover the whole band of interest without ever retuning the RF section. You'd need to split the UI into set band of interest(which tunes the hardware) and tune within band of interest (which tunes the software receiver). I can imagine something which dynamically adjusts the hardware tuning to span all receiver users' current selected frequencies, but you'd have to have some sophistication to warn a user when they're too close to the band edge and/or a lead operator who can dominate the selection. The audio path is pretty simple.. you feed the Rx audio to all clients and they tune within it. The clients need to be told what the center frequency of the audio stream is, so they can relate user command/display in actual frequency to where in the I/Q bandwidth it is. Would you give each user the same panadapter display, representing the hardware tuned band? There's also an issue if one of the users wants to be at a frequency which happens to be at zero frequency in the I/Q stream, where performance isn't so wonderful. Again, some clever arbiter that takes desired tuning frequencies from users 1..N and turns that into hardware tune frequency and user offset 1..N would be fine. Sort of a juiced up version of the current spur reduction tuning algorithm. (And, if the F5K is using the new low spur DDS from Analog Devices, the need to tune for spur reduction is lessened... or just use only one side of the I/Q spectrum.. 100kHz is still pretty wide) I think the challenge is in specifying the rule-set behavior in a intuitive fashion, rather than the actual implementation (assuming the new architecture is implemented separating UI, dsp, and hardware control more thoroughly). What about Tx/Rx issues? I'm thinking that such concept could be useful in an Unlimited Multi Op contest category. One operator would be the run operator and the other operator being the SP operator. Each would have their own UI control and each could have two RX's as in today's PowerSDR, and then with the next generation PowerSDR software, maybe even 3-4 RX's per operator. No doubt would take some practice to learn how to team operate like that, but I would think it should be doable. Yes? No?

Re: [Flexradio] 2OSR Anyone???
If it was me I would have 14 watch receivers in the passband running as robots, one receiver for the run station and one RX for the SP station. I would have the robots automatically scan a given sub-band looking for stuff needed, by analyzing every signal in their little slice of spectrum in a sub band. I'm a CW guy so it would require some means of artificial analysis of CW signals like a neural net or AI. If something showed up that was needed the robot would inform the SP op and would take that op to the correct freq to work the station. The SP op could be doing a second run in the mean time while he was waiting for the robots to inform him of SP.

The robot can only search and pounce. No packet information can be used. 3. Comply to FCC rules. This is some gray areas here. If I write a computer program that controls the radio, am I in control of the operation since I wrote the program? 4. CW only.

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.

Re: [Flexradio] 2OSR Anyone???
I think that would probably require that components (rx1, rx2, tx) inside the 5000A box be separately addressable on the firewire bus, and that PowerSDR had the capabilty to target them separately. I don't think the software is there yet, but I might be wrong. And we won't have that second receiver anytime soon, I am guessing.
