Re: [Flexradio] PC Specifications for SDR-1000
Title: PC Specifications for SDR-1000 I am not sure the testing situation for this particular person, and I can assure you that without an optimal setup (read virtually no other user processes running), you will have trouble running PowerSDR near the minimum spec. Having said that, we have run the PowerSDR software on a 600MHz Athlon. Slowing down the FPS was necessary, but it was only running at 65ish % average (not bad for 200MHz below our min spec).

Dave W9AD has been running his SDR1K on a Dell 933/512M and started experiencing some dropouts and computer effects on transmission. Just today he replaced the 933 with a 2.8G and so far the indications are that this WAS his problem. He told me that he had seen the CPU utilization rise to 80-100% with the Dell 933. His computer was dedicated to the SDR1K only. You might want to rethink the 800 megahertz minimum. --Larry W8ER - Original Message - From: Eric To: 'Tim Ellison' ; FlexRadio@flex-radio.biz Sent: Wednesday, August 31, 2005 7:21 PM Subject: Re: [Flexradio] PC Specifications for SDR-1000 My apologies for missing your earlier message. Obviously the faster the CPU, the better for real time audio applications. I am currently developing on a Celeron 2.4GHz with 512MB of ram and integrated video. My home machine is built more for PC gaming, and therefore has a bit more graphics horsepower (ATI 9800, 1GB ram). Clearly both of these are way above the minimum 800MHz machine as specified on our specs webpage. I would recommend a P4 w/800MHz FSB if you plan to do high speed CW. The faster “real-time” timer on the motherboard can improve the timing on speeds surpassing 35 WPM. There has been no testing that I am aware of on 64 bit operating systems to date. For this reason, I can’t do much more than make a general statement that I believe a 64-bit version of the PowerSDR is possible and will come to fruition with or without FlexRadio’s help thanks to the GPL nature of our software.
