Re: [Flexradio] 10 MHz GPS Disciplined Master Oscillator
At 05:14 PM 4/11/2007, John Ackermann N8UR wrote: Jim Lux said the following on 04/11/2007 07:52 PM: If you multiply it up to 200 MHz for the SDR1K, the noise would increase by 20logN, or 26 dB.. That would make the noise at 1kHz out about -124dBc/Hz. The VF161 in the radio already has a floor of about -125 dBc/Hz at 1kHz out, so it's in the same ballpark. With the huge advantage that the frequency is much more stable... We've talked about this in the past, but I don't know if there was ever a definitive answer supplied: Multiplying from 10 up to 200 MHz multiplies the phase noise by 26 dB. However, the DDS output isn't at 200 MHz, but in the HF range. Does phase noise of the DDS output then divide by the ratio of output frequency to clock speed? I would assume so.. but, since the Valpey Fisher oscillator has roughly the same performance (scaled to the same frequency) as the 10MHz the OP was asking about, the net result, no matter where you go, should be similar. You can get much quieter 10MHz oscillators (and, for that matter, quieter 200 MHz oscillators).. the question would be whether it's worth it.. The VF161 is inexpensive (relatively) and quite quiet. You could use a pretty crummy, but accurate, 10MHz source to calibrate out the aging and temperature effects, and just adjust the software tuning to compensate. There's entirely too much reliance on ovens and TCXOs these days... you've got software and DDSes which can tune anywhere, at zero cost... use it! James Lux, P.E.

Re: [Flexradio] Q35 of the Flex-5000 FAQ
Yes, pure linear, and a very big dynamic range, and no noise on the transmitted signal 120dB down on a 500Hz or so There is no brick wall filter in the transmitter PA Make it happen...without dupex filters(will not work so close on)..

If you had sufficient dynamic range, then obviously it would be no problem.. the problem is that sufficient dynamic range is pretty substantial So, I've been thinking in terms of some scheme of adaptive cancellation (which would also work with strong interfering signals), with the key being that the cancellation path doesn't need as high dynamic range (although you don't want it inserting noise, so you have to be careful about amplifiers, if any).. you'd reconstruct the interfering signal and combine it at the antenna input with reversed phase.

Re: [Flexradio] Preselection Noise Blanker
KA5MIR wrote: At my noisy qth, I have to use the noise blankers. This results in strong signals OUTSIDE the filtered bandwidth, anywhere in the 96kc passband, modulating the noise blanker INSIDE the filtered frequency range. It often causes desired signals in the filtered range to be unreadable. I would gladly trade spectrum display sensitivity outside the filter range for narrow passband filtering pre blanker or detector. It would make the difference between being able to hear stations or not. Of course it would need to be -Optional- and ideally, adjustable. You could probably have a separate detector drive just the spectrum display if you wanted to maintain a full range spectrum display with the pre-filter on. Maybe there is a way to apply the noise blanker to only the filtered audio in DSP? I've tried a range of settings for the blankers, sampling rates and agc, but can't get rid of this problem. 73' -Jeff This is an excellent question and the answer is theoretically yes with a few caveats.Here is why. The DttSP software will be deriving an impulse response for the receive chain after an ECO for the SDR-1000 (to eliminate impulse overload) and with the Flex 5000 series. This impulse response COULD BE filtered by the filters to provide a filtered impulse response. The impulsive noise that is clobbering you will then be detected and after the amplitude and phase of the impulse is determined, it will be subtracted from the receiver. This can be done before the filter or after the filter. The detection after the filter will be more prone to error. SO, it remains to be seen if we can make the detection simultaneously sensitive enough to work and at the same time have a low enough false positive detection rate to be useful. Good question and I will certainly try as it has been a interest of mine for almost two years. With the Flex 5000 hardware, I have finally been able to get textbook pulses and pulse trains and this also led to an immediate diagnosis of the problem with the current SDR-1000 impulse generator that will lead to an ECO to make this work for it as well. Expect this code to show up in dttsp 2.0 under the sdr_linux repository and in the sdr-x repository as it becomes usable. Bob N4HY -- Robert W.

[Flexradio] MixW SDR-1000 and Lockups
Folks: When using the MixW program, ONLY in the OLIVIA and MFSK modes, MixW crashes after I make a transmission, at the instant I attempt to return to receive. This happens every time without fail. I get the MixW has experienced a problem, Send a Report to MS window. It does not happen in any other mode when using MixW. I don't see any real change in CPU usage as measured on the SDR console. I have absolutely no problems whatsoever with any other software at any power level as far as I can tell. Particulars: SDR-1000 with 100W option PC - Intel Core Duo 6300 2 GB RAM XP SP 2 VAC Version 4.03 Power SDR Version 1.8.0 N8VB Virtual Com Port Version 7/09/2005, 1.0.0.4 MixW Version 2.16b7 Oct. 18 2005 Delta 66 Sound Card Decent grounding system on PC, SDR etc. It looks to me that the problem is with the MixW program itself. I have been to the MixW web page and see no reference to any similar problem. I hesitate to upgrade to the newest version as I see on the MixW reflector, new versions are often buggy, but I have no idea what the last stable version may be. I have searched the Flex KB also. Before I attempt that upgrade, I wanted to be sure that I am on the right track. I remember seeing a message sometime back on the Flex reflector that the author of MixW had released a version of that program that fixed several issues with he SDR. However, what the issues were, or what actual MixW version included these fixes are all unknown to me. Also I may be able to fix this issue by changing parameters in VAC, VCOM, or even Power SDR, and therefore may not need to upgrade. Any ideas?

Re: [Flexradio] MixW SDR-1000 and Lockups
I hesitate to upgrade to the newest version as I see on the MixW reflector, new versions are often buggy, but I have no idea what the last stable version may be. Hi Brian, I use MixW with my SDR-1000 daily (I work digital modes almost exclusively). The latest V2.18 of MixW (the most recent version available for download on www.mixw.net) seems solid to me, works well for me with my SDR, and cured a couple of strange problems. To make life fail-safe, make a copy of your \program files\MixW\ directory (that is, just copy the whole directory to a another directory named, for example, \program files\MixW Backup\). Then download and install the new MixW version. If you decide you hate the new version of MixW or you find it unstable, just delete the whole upgraded \program files\MixW\ directory and rename your copy (\program files\MixW Backup\ in this example) to \program files\MixW\) and you'll be back to what you had before. de Peter K1PGV ___ FlexRadio mailing list [EMAIL PROTECTED] 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/

Lee .. What I think is interesting is that the impact of the announcement centers around the price. The lack of information is leading to a lot of negative talk where the price is the issue and not the various features and improvements. As soon as you mention that the $2500 includes a TCXO and soundcard plus the other technical leaps, the price doesn't seem to be as large a factor and the negativity seems to melt away.

That is a fair number. I also think it should be pointed out for those who do not have a FlexRadio product, that the SDR-1000 w/ the Delta-44 @ ~$1600 (sans PC) is a phenomenal deal based on it's price performance ratio. You are talking about a radio that gives the Orion a run for it's money (see the testimonials). That is a great value. So if FLEX-5000 is beyond the radio budget, the SDR-1000 should get serious consideration. -Tim - -Original Message- From: John P Basilotto W5GI [mailto:[EMAIL PROTECTED] Sent: Thursday, April 12, 2007 1:51 PM To: Tim Ellison; 'Philip Covington'; 'Flexradio' Subject: RE: [Flexradio] Q23.

Re: [Flexradio] Q18. Why isn't the FLEX-5000C loaded with Windows Vista?
About a year ago we had a talk with the Microsoft reps, we have a corporate license for XP and several other products, the outcome was that Microsoft has no problem with downgrading a license to a older product. In our case we needed a version of the software no longer for sale, we purchased the new version and installed the old version instead. That includes the OS, so we could buy a copy of XP but install Win98 instead, they are very happy to get your money.

It certainly decodes flawlessly. It also fixed some problems in 2.16, which still worked fine for me. MixW is my primary logging program, so it is always on when the SDR is on and I always have the virtual comm running, so it's always interacting with the SDR even when I don't do RTTY. So far, so good on 2.18. I picked up the 2nd version of it IIRC and it's been fine. Been running with it since late January, I think. I have simply put each new version in its own directory (...program fles\mixW2.18) instead of the default, copied MixW.log plus the registration file and it all works fine.

Re: [Flexradio] Q23. Regarding the FLEX-5000, can we assume ...
You know it's funny but I think it's a bargain at $2500 just based on the specs in the add. I already know what the SDR-1K will do and what PowerSDR will do so all I have to do is speculate on what systems MUST be there in order to meet the features provided in the add copy and I see an overall fantastic value. I may not know the exact particulars but I can tell enough to be very excited about this radio at this price point. I presume the exact particulars will be released as soon as Flex is satisfied with their validity. Icom for example claims +40dB on their intercept point for the IC-7800. That number is really a fabrication and is arrived at by gaming the ARRL testing methodology. When Sherwood measures it for example he uses a slightly different methodology (in my opinion a more real world methodology) and he gets something considerably less. Doing these tests while they seem standardized are not really standardized and it is important to understand it is not just the number but what that number limits that is the critical thing. The ARRL testing methodology was devised in the early 70's and in my opinion is in bad need of overhaul. It wasn't a bad method for comparing a KWM-2 to a TS-520, I'm not convinced it's a good method to compare a SDR-1000 to an Omni VII. Here is the conclusion of a recent Sherwood test on the Omni VII: Attempting to measure blocking at the specified level of 135 dB @ 20 kHz, I fed in a + 5 dBm signal into the Omni VII. Two things were observed: the S meter went up from S5 to S6, and the audio went down 7 dB. Blocking is not a practical limit on the Omni VII. The meters are going in the wrong direction. Blocking is defined as when you get a nonlinear increase, it is not defined as getting an absolute decrease. The measurement is odd compared to normal measurement and its probably due to the fact the AGC is digitally derived. The real point however is not the number, but what the number means: blocking is not the limit of the system! that is the real bottom line So I am willing to wait for good analysis and not hype. 73 W9OY - Original Message From: Larry W8ER [EMAIL PROTECTED] To: Lee A Crocker [EMAIL PROTECTED] Cc: Flexradio [EMAIL PROTECTED] Sent: Thursday, April 12, 2007 3:22:48 PM Subject: Re: [Flexradio] Q23.

Re: [Flexradio] Q23. Regarding the FLEX-5000, can we assume ...
Hi, Price is all relative. Isn't the Omni-VII about $2500 or a little more, and it's not even a top-of-the line transceiver. I paid $3200 + - for my Omni-VI in 1992, in 1992 $. What does the top-of-the line transceiver of the big 3 plus Ten Tec go for? Can you compare the Flex 5K to them? Maybe not quite. Where does it fall short? Two full receivers? Close-in dynamic range? Roofing filters? QSK? Manual notch filter? What will they be in 3-5 or 10 years compared to the Flex 5K? As long as the hardware is there, the 5K software in 3-5 or 10 years most likely will be an order of magnitude more advanced, in which case in order to keep up, you can buy another big 3+ transceiver, probably for 10K+ $. The Flex 5K is a lot of radio for the price, and seems to be a good investment in future technology. I would like to see a point by point comparison of the performance of the Flex 5k and the IC-7800 (list $13466.65, discount $10588.98) or Orion II ($4395) or FT9000.

That number is really a fabrication and is arrived at by gaming the ARRL testing methodology. QEX has run a series over the past 3 issues discussing just such things. The problem of testing modern multichannel radios with signal processing is an issue is faced by more than just amateurs. Properly specifying and testing amplifiers for modulations such as COFDM (especially when the amplifier isn't being run in linear mode and is deliberately run with some clipping for improved efficiency) is quite a challenge. Simple multi tone measurements, while easy to implement with 1940s technology, and adequately characterizing systems of that era, aren't necessarily appropriate for modern systems. This has been a problem as far back as carrier telephony. For that matter, harmonic distortion or third order IM are based on a fairly simple model of deviation from linearity (i.e. a cubic term instead of purely linear). That's a good conceptual model for a continuous system but not for one that is discrete (like one that uses sampling, either in time or amplitude) There's a variety of newer (and some not so new) techniques, such as putting in a noise signal with a notch in it and seeing how much power shows up in the notch. There's also clever schemes with moderately complex signals (trivially generatable digitally) that allow you to measure things like AM/PM, various distortions, etc. Such is life at the bleeding edge of technology.. but hey, that's what we're here for, to advance the radio art Jim, W6RMK ___ FlexRadio mailing list [EMAIL PROTECTED] 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/

Q35 is correct. The ad will be changed. John P.

FAQ: Q35. What changes were made to the internal (non software) bandpass filters on the FLEX-5000? A. First, all filters are low pass instead of band pass. We don't need band pass filters in the FLEX-5000 SDR architecture. Also, the transmitter and both receivers have their own independent filter banks. Nothing is shared in the FLEX-5000.

[Flexradio] DEMI 2 Meter Transverter To Remain In Production?
Will the DEMI 2 meter transverter remain in production once the SDR-1000 is no longer available? Thanks Zack N8FNR -- next part -- An HTML attachment was scrubbed...

Re: [Flexradio] Q35 of the Flex-5000 FAQ and the PDF of the advert
I am a little confused on this issue, also. If the QSD does not need roofing filters, why was there a 160 meter filter as described below? Jeff et all, the filter that is supplied with a new Flex Radio is a low pass filter. It does not attenuate broadcast band signals. There is a problem with the SDR-1000 (many other radios too) when you live in an area that has broadcast stations in the area. Broadcast station images appear in the 160 meter band. The Flex that I just sold was sent back to Flex and had a bandpass filter installed in place of the low pass front end filter that is standard. 160 meter operation is flawless with this mod! If you normally listen to broadcast stations however, you will not be able to do that after the new filter is installed. I am sure that Gerald or Eric can supply the information on what is needed to make this change. It is a couple of new inductors and caps and can be done by the owner without shipping it back if you are handy with the iron. If all you have is a blowtorch however ... you might want to send it back! --Larry W8ER This sounds as if the QSD does need a bandpass filter and not just a lowpass filter.

Re: [Flexradio] Q18. Why isn't the FLEX-5000C loaded with Windows Vista?
Jim, You are absolutely correct. We have hundreds of PC's on our production floor, all running Windows 2000. We have not even moved to XP yet for our production machines., nor do we have any plans to do so in the foreseeable future. Yes, we have a site license and load the Win2K image ourselves when we get a new PC (with XP installed) from Dell. To switch OS's would potentially cause too much disruption to our production processes, and I think that you would want your air bag control module to be manufactured using stable systems! 73, Ray, k9DUR -- next part -- An HTML attachment was scrubbed...
