Re: [Flexradio] Rolling wave ver 1.10.1
My SDR-1000 produces broader rolling waves that travel fairly slowly. They usually appear in the first few minutes after power on and I've always assumed they were internal spurious signals generated during warm up... Jack Weber M0GKC These are due to the switching device used to obtain the +/- 12v in the SDR 1000. I replace this device with linear power supply, and the travelling waves are gone...

Re: [Flexradio] Pops on Transmit on V1.10.2
Peter I am not sure if what you describe as pops are the same as I and others have referred to as hiccups. In brief summary, I have no problems with cw, ssb, fm - modes that don't use VAC. My ownly problem is when using DigiU for WSJT operating. On receive, what I was seeing was 6-10 very brief drop-outs every 30 second period - a downward spike on the green signal line and a thin black stripe in the JT display. On transmit I was getting several drop-outs, each again lasting a few tens of milliseconds, during each transmit period. None of the changes that otehrs suggested worked for me. What has worked is changing the clock offset time in the VAC control panel, with slightly different times needed for each of the two cables (one for Tx the other for Rx). So, the transmit problem seems to have gone completely changing to 1.01. On the otherhand, the receive side works best with 1.08. It was entirely empirical adjustment. But it was striking - for example, when I set the receive time to the lowest it would go, I was getting the dropouts more than once a second. It's early days, and I fear that when I try again the old problem will have recurred. But for now, fingers crossed! David, G4YTL Peter G. Viscarola [EMAIL PROTECTED] 26/08/07 23:01 I have been running Mixw 2.18, VAC 4.07 and PowerSDR 1.10.3 beta (SVNs after the 1.10.2 release) most of the weekend and have not had a single problem; PSK31, PSK63, RTTY and a bit of Olivia. Thanks Tim. I think we're onto something here. I tried the settings from the KB you cited... and while it CHANGED the behavior, it didn't make it go away. I've tried VAC Control Panel interrupt settings from 5ms (my normal setting) to 7ms (what it shows in the KB) to even 20ms, and I didn't see any difference in behavior. On the other hand, I see LOTS of difference in behavior when I change the Sample Rate on PowerSDR's VAC tab. I've had this set on 11025 (to match MixW) -- And this works flawlessly in V1.8.0. But if I change it to something higher (up to the 48000 as shown in the KB) for V1.8.0, I get LOTS of pops (with any version of PowerSDR). I couldn't find a sample rate in V1.10.2 that works for me and eliminates the pops. So... in summary: Changes in VAC Control Panel don't seem to have an effect. Changes in PowerSDR's VAC tab seem to have a LOT of effect. In V1.8.0 Buffer Size of 512 and Sample Rate of 11025 seem to work without problem. In V1.10.2 neither these settings, nor any others I can determine, seem to work correctly. de Peter K1PGV ___ 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/

[Flexradio] Problems with PowerSDR v1.10.2 on Dell XPS M1210 laptop
I recently installed PowerSDR v1.10.2 on a Dell 3000 DESKtop, and everything works fine with a SoftRock 30m RX. I have now installed the same software on a Dell XPS M1210 laptop, (running Windows XP Home + SP2 + all subsequent updates). On this machine, instead of getting a continuously refreshed panadapter display, the display is only updated at 1 or 2 second intervals, and the display looks totally different at each update -- for example, sometimes there is a -60dB spike at 7.056 MHz, then on the next update a second later the spike appears as two adjacent rounded humps around -140dB. Average PowerSDR CPU utilisation is around 8%. Process Explorer shows that nothing else is running that takes more than about 1% CPU. I've tried several audio driver/mixer combinations, but this did not help. I also tried PowerSDR 1.8, with the same effects. Ideas anyone? -- 73 Ian, G3NRW ___ 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] Rolling wave ver 1.10.1
Thanks to Roland and Peter for those comments. I'm sure this explains what I've been seeing as I do get the same effect both with a dummy load and an antenna. It's not a big problem for me as these spurious signals seem to disappear after a few minutes. Compared to some switching power supplies that's quite tame. I wonder if this also answers Tom's original question.

Re: [Flexradio] Rolling wave ver 1.10.1
I'd agree that it's probably not an ionosound signal. Typically, ionosound systems (such as BR Communications Chirpsounders) scan at 100 KHz per second, so those types of signals will seem to fly across your panadapter display. 10-20 seconds to cross the screen seems *much* too slow, and I'd lean towards Bob's explanation (or interference from other outside sources). - Jeff, K6JCA -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Tom Homsley Sent: Monday, August 27, 2007 9:03 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; flexradio@flex-radio.biz Subject: Re: [Flexradio] Rolling wave ver 1.10.1 Bob (N4HY) thinks otherwise - *** Tom: The most aggravating feature of the SDR-1000 after the ECO's are all in is the untamed oscillator and leakage of the 15V switching power supply.

Re: [Flexradio] Pops on Transmit on V1.10.2
I have not looked at this at all, but could the PowerSDR and other programs, or OS be causing some sort of OS house cleaning that is now re-occurring at 30-second intervals on your system? House cleaning activity by the OS is likely the highest task on the system which of course cause the symptoms you describe. May swapping?

But it was striking - for example, when I set the receive time to the lowest it would go, I was getting the dropouts more than once a second. It's early days, and I fear that when I try again the old problem will have recurred. But for now, fingers crossed! David, G4YTL Peter G. Viscarola [EMAIL PROTECTED] 26/08/07 23:01 I have been running Mixw 2.18, VAC 4.07 and PowerSDR 1.10.3 beta (SVNs after the 1.10.2 release) most of the weekend and have not had a single problem; PSK31, PSK63, RTTY and a bit of Olivia. Thanks Tim. I think we're onto something here. I tried the settings from the KB you cited... and while it CHANGED the behavior, it didn't make it go away. I've tried VAC Control Panel interrupt settings from 5ms (my normal setting) to 7ms (what it shows in the KB) to even 20ms, and I didn't see any difference in behavior. On the other hand, I see LOTS of difference in behavior when I change the Sample Rate on PowerSDR's VAC tab. I've had this set on 11025 (to match MixW) -- And this works flawlessly in V1.8.0. But if I change it to something higher (up to the 48000 as shown in the KB) for V1.8.0, I get LOTS of pops (with any version of PowerSDR). I couldn't find a sample rate in V1.10.2 that works for me and eliminates the pops. So... in summary: Changes in VAC Control Panel don't seem to have an effect. Changes in PowerSDR's VAC tab seem to have a LOT of effect. In V1.8.0 Buffer Size of 512 and Sample Rate of 11025 seem to work without problem. In V1.10.2 neither these settings, nor any others I can determine, seem to work correctly. de Peter K1PGV ___ 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/ ___ 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] Pops on Transmit on V1.10.2
Although I do not advocate turning any of this stuff off, but software firewalls, virus checkers, spam checkers, spyware checkers, etc... are very resource intensive.

House cleaning activity by the OS is likely the highest task on the system which of course cause the symptoms you describe. May swapping?

In brief summary, I have no problems with cw, ssb, fm - modes that don't use VAC. My ownly problem is when using DigiU for WSJT operating. On receive, what I was seeing was 6-10 very brief drop-outs every 30 second period - a downward spike on the green signal line and a thin black stripe in the JT display. On transmit I was getting several drop-outs, each again lasting a few tens of milliseconds, during each transmit period. None of the changes that otehrs suggested worked for me.

Re: [Flexradio] Janus/ozy setup with sdr1000
I don't think we J/O will mix PowerSDR and SDR I/Q audio as you'd like. We use the PWM outputs for recovered audio on Janus and there is no mixer hardware with that - just an LPF and the pins from the FPGA. Doing an outboard summing amp would probably work for what you want. Feeding USB to Ozy via a hub in the cabinet theoretically should be fine. I'd be interested to hear if you see any audio breakups trying to move both Ozy/Janus and SDR IQ data streams on the same USB hub. Do you know what the data rate to the PC is for SDR IQ?

I have it integrated in the RF stream through relays that allow the use of the same antenna as the SDR1000 or it can have it's own antenna, there is a separate connector for this, everything mutes when transmitting. I also installed the poor man's ucb in the cabinet as well with connectors on the back of the cabinet. I also have the option of a separate antenna for receive enhancement as well. I run the software for the SDR I/Q along with everything else with no issues. This set-up allows operation of a transceiver with two independent receivers. I would like to be able to go further with the Janus/Ozy set-up, does anyone know if the Janus/ozy would allow audio from the SDR1000 and SDR I/Q to mix and output to the same speakers? I would like to feed both the SDR1000/Ozy Control and SDR I/Q with one USB cable to a hub in the cabinet. Thanks for any help.

Re: [Flexradio] Prototype VFO Dial
Hi Bill, Great idea to make it a real product! That will have a lot of customers, I believe, because: a) SDR needs at least one knob, b) I have three years' successful experience of this concept. I modified a Logitech USB mouse wheel like this picture shows: http://kotisivu.dnainternet.net/ahti/sdr-1000/VFOknob.jpg 73, Ahti OH2RZ On 28/08/07, FireBrick [EMAIL PROTECTED] wrote: If you have been reading my posts re: struggling to develope a system where I can return to contesting as I did before venturing into the realm of SDR.
