I run WSPR all night with my Flex 5000 without any problems or glitches. I am doing it with a computer that cost me about $300 to build (well, $400 now that I put an SSD in it :-) several years ago. I built the computer out of a used Antec case (the computer was being discarded), a new ASUS mobo ($70) with a now-weak AMD 2GHz Athlon x64 dual-core processor ($120 back then), 1GB of RAM ($50), an old disk-drive I had lying around, and cheap-but-adequate video and IEEE1394 cards ($60). It works brilliantly running PowerSDR with DPCs running between 60us and 160us. CPU utilization gets a bit high at 60% when running both receivers at 192kHz sampling but that's life. If I want lower CPU utilization I can go get a new mobo and processor. So the right answer is to address the problem. Hundreds of users whose Flex radios run for days or weeks on end prove that it is possible to get things adjusted properly. When the SWR is too high on your antenna at your chosen operating frequency, do you complain to Icom that their radio should do a better job of working into high SWR or do you prune your antenna? -- 73 de Brian, WB6RQN/J79BPL _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
