Re: [Flexradio] Flex3000 with N1MM: When I open a browser window, either PSDR crashes or I get a crackly audio
Mike, Like Ken said, you can't run PSDR or any other streaming audio program when your PC is stalling with 38ooo us DPC's. Download and run latencymon.exe . It will tell you (in too much detail) which program or service is stalling. When you find the worst few offenders, google them and you'll find if it's network, disk, wireless, or what. I'll bet its the wireless network adapter. If it is, you must substitute a wired adapter and disable or uninstall the wireless stuff. You'll go crazy trying to work around that. Neal Campbell, the resident guru of PC building and tuning for PSDR, has frequently said that laptops are difficult to smooth out unless you happen to get one that works out of the box. Many Lenovos do work out of the box.

Mike - Wow, with those numbers I think you are onto the culprit. Of course, you have finds the specific item. My 5 year old XP machine runs about 120. And people have reported much faster times with some current low cost systems. Ken AC0HO On Sat, Oct 26, 2013 at 6:25 PM, Michael Ruttenberg wrote: > I was seeing 38000us (!!!) this evening.

Re: [Flexradio] Flex3000 with N1MM: When I open a browser window, either PSDR crashes or I get a crackly audio
Mike - What DPC numbers are you seeing? There are several knowledge base articles on the Flex site that get pretty detained on various things to look at. When you find the troublemaker it will look so simple, "of course" is the usual thought that I have. I am not a windows expert. I long for the sort of tools that we had when I was working (IBM mainframes), but they did cost tens of thousands of dollars each.

Re: [Flexradio] Flex3000 with N1MM: When I open a browser window, either PSDR crashes or I get a crackly audio
Hi Ken It is a relatively clean install. I have PSDR, N1MM, VAC, MixW, JT65HF, VE7CC ARUser. Windows Updates are off. AVG Free and ZoneAlarm. AVG is disabled manually for a bit of improvement. DPC is a bit better with wireless turned of but then I am flying blind. I have a nano wireless USB adaptor (Edimax) but it turns out that if I turn off the main (internal) wireless then the USB one doesn't work either so I couldn't use the USB one without the internal one grabbing the signal making the USB one redundant. On winXP I used to have Gboost but it seems to no longer be supported as I installed it and dialling home fails and the forum on the Gboost site says closed. Frustrated and missing CQWW :( 9 out of every 10 loads ups don't start successfully and the 1 that does work usually bombs out with an error.

Re: [Flexradio] Flex3000 with N1MM: When I open a browser window, either PSDR crashes or I get a crackly audio
Mike - What else is running on the PCs. Any bloat ware? Anti-virus packages? Page file active? And so on. I took the simple way out, my radio PC is a clean build (from MS Disk) so no extras. Running PSDR, VAC, FlDigi and Ham Call. I start Explorer only when I need to fetch new software, Flex and FlDigi updates. I do not let Microsoft (or anybody else) install updates automatically. It solves a lot of problems. My background included performance measurement and planning (in IBM mainframes). I just prefer avoiding excess tasks. 73 Ken AC0HO On Sat, Oct 26, 2013 at 7:16 AM, Michael Ruttenberg wrote: > Hi all > > Maybe someone can point me in the right direction. > > Using PSDR 2.6.4 with a Flex 3000. > VAC (full version) 4.12 > 4gb RAM Lenovo T420 laptop (with a relatively flimsy Firewire 800 port > installed, new Firewire 400 Expresscard on the way but not yet arrived). > Win7 Pro. > Same issue on Dell Latitude D630 (Firewire 800 port).

[Flexradio] Flex3000 with N1MM: When I open a browser window, either PSDR crashes or I get a crackly audio
Hi all Maybe someone can point me in the right direction. Using PSDR 2.6.4 with a Flex 3000. VAC (full version) 4.12 4gb RAM Lenovo T420 laptop (with a relatively flimsy Firewire 800 port installed, new Firewire 400 Expresscard on the way but not yet arrived). Win7 Pro. Same issue on Dell Latitude D630 (Firewire 800 port). WinXP SP3 with 1gb RAM. Samsung SSD. The Line1 and Line 2 VAC lines playback and record are set in Sounds to 2 Channel 96000hz audio as per http://kc.flexradio.com/KnowledgebaseArticle50504.aspx. N1MM v13.10.1 My buffers are set as follows: Flex measured Sampling rate: 48khz, buffer size 1024, safe mode 1 (low latency was no different behaviour) PSDR Audio -> Primary: buffer size 1024, sample rate 48000 (was same behaviour when 2048 / 96000) PSDR Audio -> VAC1: Windows WDM-KS, buffer size 1024, 48000 PSDR DSP -> Options: all 5 buffers set to 1024 PSDR runs on the win7 machine at around 9% CPU. Basically, when I click Buck on N1MM (or open any new browser window) I get crackly audio audible on the headphones, and sometimes PSDR crashes entirely (can't remember the error but it says Continue/Quit and then I need to reboot to restart PSDR). Any ideas?
