Hi Everyone: This proposal represents a very slippery slope. Let's try studio grade gold plated cables first, we already have the sound card. We can do this today. Our music industry has no problem with good quality cables. The last thing we want to do is hardwired upgrades. If an A/D converter and CPU are added, soon to follow will be RAM, a disk drive, Internet card, then even a small screen with keyboard (maybe even viruses). Whenever frequently upgraded components are "in the box", the box will change at least once a year. Then you have an Icom or Yeasu. In fact we already have Icoms and Yeasus of all shapes, sizes and colors. They're not as good yet but they keep introducing new and improved models to sell. I spent money on studio grade connecting cables from Sam Ash and Guitar Center and spend all my time hamming or trying to improver my settings. NOW, if anyone wants to talk about changing from BNC to SO239, I'll be very interested. Jerry Larry Loen <[EMAIL PROTECTED]> wrote: Jim Lux wrote:

As long as the Mini-ITX is separate from what I'm asking for, analogous to what is done with the Dell package, I have no problems with this. But, I want the radio _itself_ to be portable or at least reasonably "transportable." That means a 12v unit and also a unit as a whole that can be put into the bottom of a carry on bag for an airliner. Something physically not much bigger (maybe not bigger at all) than the current unit. I just want it very _slightly_ smarter in roughly the same package. I want it to be just a little more like a conventional radio and not outsmart ourselves with added complexity. Conceptually, take out the 2m transverter and insert the A/D D/A CPU-based package in its place. That's all, at least physically. Start adding in a full Mini-ITX PC as a single, indivisible unit and the whole suggestion becomes more problematical. Flex (whatever it does) is not going to have a gigantic product line. I vote for a KISS USB peripheral approach because it would acutally serve a _wider_ menu of needs. As I read Jim's idea, there's still a second computer involved anyway, so the Mini ITX, as a "platform" has more minuses than plusses, I think. Besides the sheer nightmare of the wires that motivates this plea, the current package is really a "base station" unit and not terribly portable, even though I'm willing and able to do it. But, the current SDR 1000 really kind of resists going portable. Or, put it another way, taking it portable, at the very least, disturbs all those darn wires. You hesitate in the way you might not with another rig. If it wasn't a 12v rig, I wonder if it would even occur to anyone to try. I don't think having the Flex unit itself having ethernet is critical at all. Nor particularly desirable. Given that (in my suggestion), the major smarts, including the DSP logic, stays off the SDR itself and that the SDR hardware remains primarily latches (now supplemented by a D/A A/D process _and no more_) then there'll be a second PC in the picture that can and will do the required networking. Even in Jim's suggestion, this appears to be true. Leaving the SDR off the network (and, therefore, no direct internet connection) simplifies "who controls the radio" questions anyway. So, again, if the Mini-ITX machine is separate, it's no problem in my view of it. I want the current form factor (with fewer plugs) to do the job. If ethernet is somehow the only way to do my version of this, I'll go for it. But please, no "all in one" kind of unit. Keep the hardware as simple, small, 12v, and as dumb as possible. Ideally in the very same box or one only slightly larger. All I really want to do is _mildly_ upgrade the SDR 1000 to contain enough horsepower to do the D/A and A/D so we can get rid of all those wires and all those easily disturbed plugs. Not a whit more. If it weren't for the delicate wires, I'd say what we have is already perfect. But, the wires just have to go. > > Maybe this is something that some decent soul will produce as a > product.

In my version of it, I don't care if the firmware is some simple embedded "thing in itself" or has a full-blown Linux underneath. But, if things go wrong, it has to be able to be powered off and on just like today's unit, with not much delay before being "ready" after power on. If there's a Linux in there, it had better be bootable from some sort of re-writable ROM and very spartan. The command set need not even be as sophisticated as Kenwood CAT anyway. "Set latch 1 to 55" and "receive current D/A packet of data" would be enough of a command set, with adequate publication of same (or, easily inferred from the schematic). The rest of the complexity would be outboard and could reasonably be expected to be the current PowerSDR console, the new one, or something else. No "feature creep" please. I don't want much more than we have already. Less is definitely more, here.
