***** High Performance Software Defined Radio Discussion List *****<br><br>Hello Chris,<br> How about posting a link to capture card sdr, sounds interesting.<br><br>Thanks,<br>Al<br>KE5EUP<br>KCARC,ARRL,TAPR,AMSAT,HPSDR<br>

<br>><br>> On another list I just read instructions on how to modify<br>> a television capture card. These are intended to put a<br>> TV picture in a window on a PC but they have tunners<br>> and ADC chips and sell for cheap. This guy pulled off

<br>> you want to. Personally I think I'm going to pass on the Janus<br>> board. It does not do much more then my M-Aduio Deleta<br>> card that I have in my PowerMac G4. I'm waiting for a<br>> system that can do tens of mega-samples per second

<br>>><br>>> I had gone ahead and purchased the Janus and Ozy boards even though I<br>>><br>>> do not own the SDR1000. I was hoping to purchase the SDR1000 and a<br>>> PC capable of handling the software with ease. (I mainly use Macs
<br>>> and my only PC is woefully inadequate for the job) Now that the<br>>> SDR1000 is to be discontinued, it looks like I will not be able to do<br>>><br>>> what I had planned (I was still about 6-8 months away from saving up
<br>>><br>>> to the purchase price). So... I have decided to back out of the SDR<br>>><br>>> world until a later time. Meanwhile, the Janus and Ozy boards,<br>>> already paid for, but of course, not yet delivered, will not be of
<br>>> much use to me as I really need to save my money for a much longer<br>>> time before purchasing an SDR radio. Does anyone out there wish to<br>>> purchase a set of already built boards, to be delivered as soon as
<br>>> they are sent to me? I only need my cost back out of them, and all I<br>>><br>>> can do at this time is promise to deliver them when they are<br>>> delivered to me. I do not need to take any money in advance, -- I
<br>>> only need to have a guarantee that you will purchase them when they<br>>> are delivered sometime in the latter part of May, or early part of<br>>> June.<br>>> I will still lurk on this site, learning all about these wonders
<br>>> (which are beyond my total comprehension, but still fascinating to<br>>> me) and maybe someday later, I will join the SDR group of pioneers --<br>>><br>>> not in the first wave of explorers, but in the second or third wave
<br>>> in the future. Meanwhile, I continue to support TAPR as a member and<br>>><br>>> have the greatest admiration for all of you so involved in the<br>>> exciting design and production of this cutting edge.
