It could be a dedicated box, but my 275 dollar solution, as such, doesn't assume that. It assumes, rather, that you have some aging ATX box with adequate peripherals and an adequate power supply. That means you can reuse keyboard, display, CDROM, hard file, etc. There's no reason to suppose these peripherals need any sort of upgrade in this scenario which presumes that running the SDR console better is the problem. So, we need just the basic "horsepower." Recall that I am totally glitch free with my existing 2.4 GHz P IV. So, while a dedicated machine is one option, a simple horsepower upgrade is also an option. and (of course) a bit cheaper. My suggested components, then, would be just enough to get you there if, say, you had an existing 700 MHz or perhaps an even faster MHz Celeron machine that wasn't delivering enough performance for your SDR work today. It assumes you're willing and able to "gut" the existing box and put a new motherboard in there plus memory and CPU and reattach the rest. Not everyone could do that, but I suspect most people here could, presuming they have a remotely standard desktop. The particular assumptions my friends dug up had a Micro ATX form factor, which would fit the majority of machines that aren't the so-called "small form factor" machines (in other words, mini towers and anything like one). It would fit all my several surviving ATX machines. I'd have to double check total power consumption, to ensure my power supply cut it, but that would be about it. I also talked about a second machine, however. That would obviously cost more, so we can continue with your note and with your original assumption. I just wanted to clarify that there's really two scenarios here which I may have not clearly distinguished. On to the other. >The parts below for $275 almost get you there, but not >completely.

It's not too hard to find machines like that. You sometimes have to be ready to buy "right now" but such machines show up with some regularity. The last time I faced what you suggest, and had to do a whole machine's worth at once, I managed to find a then state-of-the-art machine a friend was selling for about. . . 500 dollars, which is ballpark to what you are dealing with here. The D44 is kind of a "don't care" in that if you have it, you reuse it in any scenario and if you don't have it, it has to be purchased in any scenario. So, your idea certainly works, also, which makes both of my scenarios whole (presuming, in this scenario, that one wants a dedicated box anyway -- otherwise, see above). But once we hit the 500 dollar range, I would actually start looking for the "specials", unless I really wanted particular components. >-Tim >--- >Tim Ellison ( [EMAIL PROTECTED] ) >Integrated Technical Services ( http://www.itsco.com ) > > > Larry WO0Z _______________________________________________ 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 Homepage: http://www.flex-radio.com
