Re: [Flexradio] MAKE BACKING UP A HABIT
Hi, last week I have exercised imaging the disk of my notebook. After several tries I have a solution which needs not to take the disk out of your notebook: With Paragon or Acronis you can image a bootable disk via the usb-port. You only need a case for a usb-disk for a few bucks and start the imaging after booting from the Paragon or Acronis Recovery CD, which loads unix or linux on your notebook.

[Flexradio] Noise Blanker and large S9+ signals outside of passband
I've noticed that when NB or NB2 are engaged, large (S9+) signals that are outside of the filter end up interacting with the noise blanker causing the noise floor to vary in proportion to the amplitude of the large signal. For example, if clicking the NB results in a 6 dBm decrease in the noise floor, the amplitude changes in the large signal outside of the passband will cause the noise floor within the passband to increase by as much as 6 dBm. It would be nice if the noise blanker could be restricted to only operate within the passband. This wouldn't be an issue if the noise blanker was so darn good on PowerSDR! ;-) Anyone else see this same behavior or do I have something configured wrong? 73, Kurt KC9FOL ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
Re: [Flexradio] [OT] please backup your PC
I back up my PC weekly and therefore have never had a hard disk fail on me. Although I had set the same automated back-up (to CD-R/W) on my wife's PC, she was much more careless about it (never left her PC on long enough for the back-up to take place, never swapped out the CDs, etc.). And ofcourse fate struck. However, she was saved by the skin of her teeth thanks to Linux. In this instance, it was the Windows boot sector that had failed. For some reason, I had once also installed Linux on her PC, which would boot up when Windows would no longer. I was able to use Linux to transfer all her important files (including emails and years of contacts) to another machine in the nick of time, because the hard disk progressively failed more and more.

PM me if you would like any particular info on my setup. Kent/KX5KW All noise blankers operate on wideband signals. They do this because the filtering does pulse stretching making it very hard to determine with a good probability what is and isn't a pulse. ALL blankers modulated the wideband signal because they gate the receiver off. NB2 does this less than NB because it attempts to take an insufficient (sic) statistic on the signal and replace what it sees as a pulse with a reasonable candidate for what the signal should be. This is based on find the rank order mean of the signal in the vicinity. Neither of these is perfect but if the pulse noise is periodic you will modulate the entire passband since the gating on and off of the receiver is like a mixer. If a strong signal (such as CW) is inside the passband and it pass the stupid test for pulse, it will be gated off. This can and SHOULD be replaced with a test for widebandedness so strong CW signals do not pass the test. I will work on this. The ultimate tool will be a pulse noise subtracter. It is not a blanker at all (gating the receiver off). A pulse is detected and then its amplitude and phase are determined. An inverse of this is subtracted from the incoming signal. This works like noise cancelling headphones by injecting an opposite, negative copy of the signal to null it. This has the advantage that it is a linear operation. It cannot cause mixing. Furthermore, single pulses can be excised. How can this go wrong? A false positive detection will remove actual signal by subtracting the false negative of the pulse. A fail to detect will not remove the pulse. Another plus is that this will operate over much more of the pulse than the blanker. There are quicker and not quick things in this we can do. All new development is behind a) wideband image rejection b) downsampling 192000 and 96000 internally to get the same shape factor on the IF filters that we have at 48000. c) IMPROVE the shape factor by downsampling to all divisors of 48000 d) finalize the correct settings and operation of the LMS filtering to work on complex signals with the correct parameters.

Re: [Flexradio] Buffer and sample rate
Ed, I would suspect that the issue is really with the hardware/driver buffer size as your CPU should have no trouble keeping up with 96kHz. Try setting both the driver buffer size (in the FLEX-5000 Control Panel shortcut on your desktop) and the Audio buffer size (Setup Form - Audio) to 512. Then go to the Setup Form - DSP Tab and set the RX to 4096 and the TX to 512.

Re: [Flexradio] I'm glad to report success with
I've consulted with the Propagation Gods and they inform me they fully intend to improve things in the next year or so, just hang tight. I told them that wasn't satisfactory.

Re: [Flexradio] Noise Blanker and large S9+ signals outside of passband
I have had excellent results with NB2 for the line noise around here (its bad enough to keep me off the radio if I cannot use it, the regular NB doesn't help). It seems to me that the problem Kurt is describing has gotten worse over the past 6 weeks or so. Just an observation in case anyone sees something that changed to exacerbate the problem. It does make NB2 almost unusable in contests with very loud signals. Neal Campbell www.abrohamnealsoftware.com AIM:nealk3nc On Dec 19, 2007, at 10:47 AM, KX5KW wrote: Kurt, You're not the only one. It makes the noise blanker almost useless for me since there are always other signals in the 96kc if range. Bob McGwier, N4HY, has some excellent ideas for noise cancelling in the code, but he has a LOT of other projects going on. I use a modified version of MFJ-1025 here and although it is very finicky to get set up and must be reset any time you change frequency, I would not be able to hear some signals without it. PM me if you would like any particular info on my setup. Kent/KX5KW On Wednesday 19 December 2007 08:21:44 am Kurt Vangsness wrote: I've noticed that when NB or NB2 are engaged, large (S9+) signals that are outside of the filter end up interacting with the noise blanker causing the noise floor to vary in proportion to the amplitude of the large signal. For example, if clicking the NB results in a 6 dBm decrease in the noise floor, the amplitude changes in the large signal outside of the passband will cause the noise floor within the passband to increase by as much as 6 dBm. It would be nice if the noise blanker could be restricted to only operate within the passband. This wouldn't be an issue if the noise blanker was so darn good on PowerSDR! ;-) Anyone else see this same behavior or do I have something configured wrong? 73, Kurt KC9FOL ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/ ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
Re: [Flexradio] Buffer and sample rate
WSJT only operates at one rate (11.025 kHz) so there has to be some resampling taking place between PowerSDR and WSJT. That resampling is probably the real culprit. The bigger you can make the PowerSDR buffers, the better off you are, probably, especially since latency isn't an issue with the WSJT modes. 73 Frank AB2KT On Dec 19, 2007 12:06 PM, Eric Wachsmann [EMAIL PROTECTED] wrote: Ed, I would suspect that the issue is really with the hardware/driver buffer size as your CPU should have no trouble keeping up with 96kHz. Try setting both the driver buffer size (in the FLEX-5000 Control Panel shortcut on your desktop) and the Audio buffer size (Setup Form - Audio) to 512. Then go to the Setup Form - DSP Tab and set the RX to 4096 and the TX to 512.

Re: [Flexradio] Buffer and sample rate
I have found that whenever I change sampling rates in PowerSDR and the SDR-5000 Control Panel, I must totally exit PowerSDR and restart. Otherwise, my transmit frequency moves to the lower image frequency.

Re: [Flexradio] Buffer and sample rate
Thanks Eric and all that replied, before changing to Erics recommended settings I gave it another try, everything the same as yesterday. For what ever ression the WSJT tones were crisp and clear.

[Flexradio] POWERSDR ON A LARGE SCREEN DISPLAY
I went out last night and bought a Westinghouse 22 (ultra bright) wide screen LCD Display. Using my Flex 5K is even more fun now. I'm still running the monitor at 1024 X 768 just like I was on my 15 display so everything on this display looks so much larger. I could adjust the resolution all the way up to 1680 X 1050 but I prefer the larger size especially with PowerSDR. Even at this resolution it does not look grainy and the aspect ratio looks good. Looking at the Panadapter on this 22 Display is a whole new ball game. I feel like I am sitting in a flight simulator. Prices are coming down fast. I paid $199 for this monitor as Best Buy. 73 de Paul Zora K3PZ Port Saint Lucie, FL www.k3pz.com -- next part -- An HTML attachment was scrubbed...

[Flexradio] Backup
Gerald: When using Office (and I have used it since it's inception), change your default file locations of the .ost and .pst files into your My Documents folder. That way, if you do a fast a dirty backup (like I do every weekend) of your My Docs folder, you at least have a full backup of your .ost and .pst files. These files contain all those important Outlook information.
