I only have Mac computers here (personal preference). Two iMacs, 2 MacBook Pro laptops and one MacMini. I have NO problems with PowerSDR, absolute zero, on any of the five Macs. PowerSDR runs on it's own sector under Windows 7 64 just as if it was on an "inexpensive PC".
I was actually told by one of the Flex reps at Dayton last year that it is preferable to run PSDR on a Mac - don't ask me why, but that was what he told me when I asked him how well Flex and PSDR worked with Macs. That prompted me to buy a Flex 5000......it worked so well on my Macs that I also bought the 3000 and 1500. All of my Macs come standard with Firewire 800 - it has been plug and play for me, right from the getgo I usually run PSDR at almost full screen with no problems on my new 27 " iMac. Just FWIW 73 John, ZS5J and C91J On 14 Jun 2012, at 5:42 PM, Robert Costa, KB6QXM wrote: Let me understand something. With the inexpensive hardware that is available that will run PSDR, why do people try to bend their APPLE products into running real-time audio processing applications. Why not just buy a dedicated $300 PC for the Flex and be done with it? I am perplexed at all of the tweaking that is done on the Apples to run PSDR. One OS sitting on top of another and an emulator to glue it all together. Nothing native. Why go through all of that hassle? Just curious. 73, Robert KB6QXM "Ham Radio Open Conversation" Yahoo group owner/moderator ----- Reply message ----- From: "Sheldon Hartling" <ve1...@rac.ca> To: <FlexRadio@flex-radio.biz> Subject: [Flexradio] Touch-Screen All-in-One computer (late-2009 iMac) Date: Thu, Jun 14, 2012 8:31 am I've made a little progress and the iMac 27 is working better. Here's what I've done * Turned off thes features in Windows 7 control panel Programs & Features: Tablet PC components; Windows Gadget Platform; XPS Services; XPS Viewer; * Installed GBoost (www.gzero.com) and run it before PSDR; * Switched to Legacy Firewire driver; * Stopped "AppleOSSMgr.exe" process (not sure if this will make a difference, but its been attributed to DPC spikes on some support websites); * Reduced the size of the PowerSDR main window. This last one is interesting. If I resize PSDR to take about 3/4 of the 27" screen it seems to run normally. Once it reaches that size, if I make it any bigger the CPU% display stops updating and the FlexControl works erratically. Is this a known issue? As soon as I shrink it back down the Flex-Control catches up. The DPC Latency is running in the 60uSec to 140uSec range with bumps to ~500 every half hour or so. I left it running PSDR and DPC Latency Checker overnight last night but the display was messed up this morning and the latency checked showed a max of 4000. So there's still something causing occasional spikes. The longest delays normally measured with Latency Mon are in NDIS and the Nvidia network controller. I tried bumping the nVidia NIC driver back a version but it didn't seem to make any difference. Any advice appreciated! Especially from those who are successfully running PSDR on an iMac. 73, Sheldon VE1GPY From: Sheldon Hartling <hartl...@netpathinc.com> Date: Wednesday, 13 June, 2012 2:42 PM To: "Justin M.
