[Flexradio] Another SDR-1000 Phase Noise Measurement
A while ago I did some testing on the SDR-1000 to see whether an external 10 MHz reference oscillator gave worse phase noise performance than the standard 200 MHz oscillator. Then, John, K20X, did some excellent work (see http://www.exothink.com/SDR/SDRPN/index.htm) I've now done some follow-up measurements that build on John's work. Where he measured the noise of the DDS system directly, this time I measured the noise at the transceiver output so that the entire system -- including sound card (a Delta 44) -- was measured. I measured the SDR-1000 when driven by the standard internal oscillator, a fairly noisy Marconi signal generator, an extremely quiet Wenzel Ultra Low Noise oscillator, and an HP Z3801A GPS disciplined oscillator. I also measured a couple of other HF rigs that I had handy to get some idea of how the SDR1000 compared to other transceivers. The results are at http://www.febo.com/pages/hf_phase_noise/index.html I haven't done a lot of deep analysis yet, but here are a few observations: 1. The SDR-1000 with standard oscillator performs about the same as the other HF rigs I tested; it was a bit worse than the other modern rigs below 10 Hz offset, quite a bit better than them between 10 Hz and 10kHz, and somewhat worse at distant offsets. 2. The SDR-1000 has many spurs in the range of about 60Hz to 10kHz offset. I suspect these come from the PC-mounted sound card. They are all at least 60dB down from the carrier, so most likely wouldn't be noticed on the air. Using an external sound card like the Edirol would probably reduce computer-generated spurs, and I'll bet the new SDR-5000 will be much better in this regard because the analog stuff is all inside the box. 3. The results with various 10MHz reference oscillators compared to the standard 200 MHz oscillator were surprising, but make sense if the DDS chip incorporates a PLL: (a) at close offsets -- say, 1 to 10 Hz -- a good external reference shows better phase noise than the internal reference. (b) at mid offsets -- say, 100 Hz to 10 kHz -- there's not much difference between any decent oscillator and the internal reference (the Marconi generator is much worse, but that's why I included it!). (c) at distant offsets -- beyond 10kHz -- two things happen: first, the external references -- even the Marconi -- are just about the same, and second, the internal reference is almost 10dB better at 30 kHz. The fact that all the external references converge indicates that we're seeing the loop filter bandwidth of the PLL that the DDS chip uses to multiply the external reference. The internal 200 MHz crystal oscillator doesn't use this PLL, so it can provide better performance. But... there is something going on from about 30 kHz that causes the noise to increase, no matter what the reference. At 100 kHz, the internal reference has only a couple of dB advantage over any of the external references. Unfortunately, my measurement system only looks out to 100 kHz, so I can't tell what happens further away. I see somewhat similar results on some of K2OX's DDS measurements; his measurements indicate that the noise starts going down again at perhaps 300 kHz offset. 73, John ___ 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/

Phil Hi Phil, I checked the stability of the SDR1K several times ... nothing scientific Here is how I did it: I tuned the the SDR1K to a frequency standard like WWV on 10mhz or 15mhz from a cold start (my shack is rather cool at just under 70 deg F) I also fired up MixW and clicked on the carrier while in PSK mode with an audio frequency of 1500hz with AFC engaged. The AFC in MixW will follow any drift with a direct readout in hz. I plotted the drift at 5 min intervals. The result is that there is fast drift (my SDR1K) up in frequency for the first 15 minutes ... in fact the drift is so fast that there is a perceptible 'lean' to the WWV carrier on the MixW waterfall trace. After 15 minutes the 'lean' in the trace is no longer perceptible the drift has slowed down to about 5 hz per minute to the 30minute mark. From the 30min mark to the 45min mark the drift still continues (in the same upward direction) at a decreasing rate. After 45 minutes there is no perceptible drift for any period of time. The total drift from cold start to complete stability (45 min later) is about 170 hz. For my general application (digital and CW) there is no drift after 45min. Knowing this I fire up and shut down according to my operating habits ... no need for 24/7. PS For general information I originally purchased the SDR1K barefoot (1w) and used it to drive the PA section of an old tube rig which worked fine. With the discontinuation of the SDR1K I broke down and purchased the 100w solid state amplifier and installed it I have to say it works wonderfully. I have it and the 35amp power supply installed in the closet in the spare bedroom behind the wall of our computer room. My desk looks exactly the same as the xyl's everything is controlled by the computer/sdr1k ... including antenna switching etc. (no fan noise hi hi) I did a stability run with the new arrangement and found it to be identical to previous stability test runs.

Re: [Flexradio] Reference Oscillator
At 08:20 AM 6/2/2007, Frank Mayer wrote: Any ideas on a external reference TCXO? Frequency, etc. You want the multiplied up frequency to be in the 200MHz area (so that you don't get too many spurs when generating the HF LO).. The DDS can use any integer multiplier from 2-N (I can't recall what the biggest N is, but clearly, any N=20 works, because 10 MHz is popular). Phase noise increases as 20log(N), so a quiet 50 MHz oscillator is better than a 5MHz oscillator only 10 dB quieter. The quietest crystals tend to be in the 80-100 MHz range (these days), but because of the popularity of 10MHz references, there are a fair number of outstandingly good 10 MHz oscillators around. I think the PowerSDR software can accomodate pretty much any frequency (e.g. if you have a 66.124239 MHz oscillator, and program the DDS for x3 at 198.372717 MHz, you can configure appropriately) (I assume the spur reduction algorithm is based on the programmed digital frequency, not on some sort of hard coded numbers) THis might not have helped you all that much, but at least you've got some of the tradeoffs to work with. Mostly it comes down to what's available cheaply. I have seen some Wenzel units on the internet. Wenzel makes good oscillators, but they do vary. You might also look at whether it's ovenized or not, which will affect the long term stability. One of the quietest crystal oscillators I have at work is from Wenzel, but it's not fully ovenized, so it changes with age and temperature, but this is no problem, because it's intended to be locked to an external frequency standard.

[Flexradio] Scratchy CW sidetone when using a bug?
I have a Vibroplex bug that I've been using with the SDR-1000. The problem is a scratchy sidetone. This same bug does NOT has a scratchy sidetone on my ICOM 756 PRO II. It didn't sound scratchy on 746 PRO at my local HRO store. A local friend of mine did NOT hear scratchy dits on my signal when I was using the SDR-1000 with this bug. If I set the ramp in setup up to 20 ms or higher (25 is the max), most of this goes away. I don't have the problem on the built-in keyer via the rear jack unless I reduce the ramp to a real low value. The bug is connected to a COM port built into my PC. I also can use a straight key on the COM port. It doesn't sound scratchy unless under normal use, but will sound scratchy if I lightly tap it. I operate no faster than 16 wpm. I don't know how a high ramp value will affect the transmitted waveform. I don't want to use a high ramp value just to make the sidetone sound more pleasant. I suspect the overwhelming number of CW ops use a keyer, either internal or external, with the SDR-1000. Again, the scratchy sidetone is NOT present on a couple of ICOM rigs. I suspect is has more to do with the quirks of the SDR-1000. It is rather annoying. I'd like to solve this one. How do I know if it is really the bug or the rig? Perhaps I want to use a separate sidetone separate from the one in the rig. BTW, I am using the FA-66 sound card at 48000 (mostly for better DSP options such as sharper filters). Changing the sample rate doesn't seem to make a difference. The PowerSDR version is v1.8.0. 73, Steve N6VL -- next part -- An HTML attachment was scrubbed...

Re: [Flexradio] USB adapter repair
Sterling, Are you sure the USB is working properly? Or have you moved the adapter to a different USB port? Make sure that you have the correct driver attached to the port that corresponds to the USB adapter. Sometimes we move or add something that might disrupt the original settings. The USBIO driver is contained in the c:/program files/FlexRadio Systems/USBIO If you are sure that the USB and the device driver are correct, just be sure to attach a detailed note to the adapter so it can be checked out. 73, Dudley WA5QPZ FlexRadio Systems (512) 250-8595 Email: [EMAIL PROTECTED] Web: http://www.flex-radio.com/www.flex-radio.com -- next part -- An HTML attachment was scrubbed...

[Flexradio] big time problem working the HV0A
HV0A was on 14.091 listening up 3 to 6. It's not uncommon for a RARE rtty dx station to have a wide split. He was solid s9+ Most of the stations he worked where up at the 6 or even higher. So...I moved the Pan over so he was at the far left edge of panadaptor Which gave me the 14.097 mark on the right (4x) zoom Hit split and Sub RX to try and find, see, who he was working. But when I would do that, gradually the noise would increase, lots of snapping and popping and I'd see the CPU rocket up to 73% and then freeze up. I'd have to shut off the sub rx and after a few moments, the noises and display would return to normal. I was using WinWarbler on one screen to call the HV0A, and my logging program (which wasn't doing anything) and PowerSDR were on the main monitor. Fast 3.2gig machine 1 gig of ram. Video card is NVDIA GeForce 6800. And I was connected to the cluster. FA-66 set for 192 with a sample rate of 12000 Normally, cw, or even digital ops without the sub rx never go above 25% CPU use. Unfortunately I couldn't hit the Task manager to see what was grabbing cpu. As soon as I turned off the Sub RX, the snaps, crackles and Rice Crispies Pops lessened and the Power SDR returned to normal, not instantaneous, but quickly. I had been working a number of rtty stations up and down the band with complete success till this situation arose. So what settings do I have wrong. I've worked a number of cw stations split recently without this behaviour. I just repeated the experiment with a less wide split. now up to 78.2 cpu percent task manager sayd Power SDR.ex taking 72 percent I could see the 'out' light on the fa-66 flickering and then PowerSDR returned to normal. I tried this with 2x zoom and 1x zoom with similar results. - A cynic smells the flowers and looks for the coffin. - Bill H. in Chicagoland webcams at http://76.16.160.118:8080/ weather at http://hhweather.webhop.org ___ 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] big time problem working the HV0A
It is something running on the box that is stealing system interrupts that is causing the latency. Some programs, such as antivirus, anti-spyware, software firewalls, and even some e-mail programs can cause this behavior. Even though programs appear not to be doing anything, if they are loaded, they are doing things. See what is loaded in the bottom task bar. It could be one of those programs causing the problems. I recommend that you unload un-essential programs one at a time to see if that helps. Also do the system optimization techniques that are listed in the Knowledge Base You can also drop you sampling rate to 96 KHz. Make sure you chipset video drivers are up to date (for NVIDIA video, it is recommended to uninstall the existing driver before installing a new one). And you may need to optimize the FA-66 buffers and the PowerSDR audio and DSP buffers. This process is trial and error since one setup is the same as any other one. Smaller buffers can cause popping since it works the CPU harder. -Tim -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of FireBrick Sent: Saturday, June 02, 2007 8:01 PM To: FlexRadio List Subject: [Flexradio] big time problem working the HV0A HV0A was on 14.091 listening up 3 to 6.
