Re: [Flexradio] Transmit euqalizer + Gate causes lock-up in SVN821
This is a Firstin Lastout software conflict. Close everything (especially the browser), uninstall PowerSDR and remove All the software except the database (store the database off of drive C:, put it on a floppy if necessary). Reinstall any required Microsoft and Delta/Roland drivers from new downloads (just as a precaution). Reinstall PowerSDR and skip the Import from Database option. Restart PowerSDR and view the CPU usage. It should be below 20% - mine is around 10% with Noise Gate, Vox and Equalizer on. Restart the browser and wait till things settle down. It should settle down to below 30%. If this is the case then reload the database and you should be back to where you started sans the excessive CPU usage. It is also possible that there was a DLL conflict or corruption. The regular Control Panel uninstall the reinstall should correct the problem. Otherwise the PowerSDR DLLs need to first be removed manually the use a new reinstall. -- next part -- An HTML attachment was scrubbed...

Re: [Flexradio] Transmit euqalizer + Gate causes lock-up in SVN821
Edwin, Nice to know I'm not alone. Others have contacted me privately with the same issue also. In the mean time I have done some further experimenting. I have checked both 1.8.0 and 1.9.0SVN821 - there is no difference. Also I have started with a clean database, just in case, again no difference. It is very clear that the issue occurs only when both Gate and Transmit EQ (did not check RX EQ) are enabled. In that case, when starting the transmission with a closed Gate, the CPU% shoots up to 80-90%. If and when the Gate opens, CPU% immediately drops to the usual 20% or so on voice transmission. Sometimes the Gate will open after a delay, other times not at all (see below). All information prior to the Gate opening is lost (monitoring with a second receiver). A higher audio buffer and especially a lower DSP buffer will make a difference: with audio buffer=512 and DSP buffer=4096 the Gate will not open on transmission. With audio buffer=2048 and DSP buffer=1024, the Gate will open after a delay, cutting off the first syllable at best. Changing the sound card sampling rate makes no difference. Lowering the system priority from High (my usual setting) makes no difference, it doesn't get worse. Hope this helps resolve this issue. 73 de Joe - AB1DO - Original Message - From: "Edwin Marzan" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; Sent: Monday, January 08, 2007 13:58 Subject: Re: [Flexradio] Transmit euqalizer + Gate causes lock-up in SVN821 > Joe, > > Using the official latest realease 1.8.0, when I use the equalizer and the > noise gate I notice that CPU cycles shoot up and PowerSDR slows down > dramatically.

Re: [Flexradio] Transmit euqalizer + Gate causes lock-up in SVN821
Edwin, Nice to know I'm not alone. (Others have also contacted me privately with the same issue). Interesting is also that we are both using 3GHz Pentium Processors with 1GB of RAM and a Delta 44. Don't know if that is relevant, just an observation. In the mean time I have done some more experimenting. First I started with a clean database, just to make sure I had the default settings. I then adjusted the Gate setting such that enviromental noise was blocked (around -23 here). As I was doing so, I immediately noticed that the moment the Gate is closed (blocks), CPU% increases. Without EQ on, the increase is small however, only some 5-10%. The problem only occurs when both Gate and EQ are on and the Gate is closed (blocking environmental noise). The CPU% then jumps to 70-80%. Speaking in the mic, the Gate opens after a delay at best, but usually not at all. Sometimes, on the first over, everything will work OK, but on subsequent overs there is either a long delay or no audio transmission whatsoever. All information before the Gate opens is lost. Once (and if) the Gate is open due to audio in the mic, CPU% immediately drops to the usual 20% or so on transmission. The closed Gate (in conjunction with the EQ) seems to cause the problem. The problem occurs in both 1.8.0 and 1.9.0SVN821. Adjusting the audio and especially the DSP buffers makes a difference. Lowering the DSP buffer from 4096 to 1024 cuts the first syllable as opposed to no audio getting through at all (monitoring with a secind receiver). Without EQ on, the Gate will open immediately no matter what the buffer settings and all of the audio gets through to to the second receiver. My process priority is High. Adjusting this down makes no difference (as I would expect). I have not tried the Real Time setting yet. Hope this helps resolve the issue, or helps someone point out what I need to adjust to make Gate and EQ work together. 73 de Joe - AB1DO - Original Message - From: "Edwin Marzan" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; Sent: Monday, January 08, 2007 13:58 Subject: Re: [Flexradio] Transmit euqalizer + Gate causes lock-up in SVN821 > Joe, > > Using the official latest realease 1.8.0, when I use the equalizer and the > noise gate I notice that CPU cycles shoot up and PowerSDR slows down > dramatically.

Re: [Flexradio] Transmit euqalizer + Gate causes lock-up in SVN821
Joe, Using the official latest realease 1.8.0, when I use the equalizer and the noise gate I notice that CPU cycles shoot up and PowerSDR slows down dramatically. The ptt is sluggish in both directions. Turn off the noise gate and the response is back to its normal zippy self. I'm using an HP Media Center PC with 3.0Gig Pentium Processor, a gig of RAM and a Delta 44 Sound Card. Our symptoms are not exactly the same but there is definitely something going on that puts a drain on our systems when the equalizer and noise gate are used together.

[Flexradio] Transmit euqalizer + Gate causes lock-up in SVN821
Hi All, Using SVN 821 and I have noticed that when trying to use both the transmit equalizer and the noise gate, PowerSDR will not transmit any audio at all in SSB. Lowering the Gate value does not change anything. The panadapter freezes, cpu processing shoots up to for me an unprecedented 85-90% (usually around 20% when transmitting audio) and no audio is transmitted. PowerSDR itself does not lock up. No other DSP or other processing of any kind is used. If I disable either the Gate or the Transmit Equalizer, there is no problem, i.e. I can use either separately but not both together. Is anyone else experiencing this? Or is there something I'm possibly overlooking?
