[Flexradio] Flexradio 1500/PowerSDR 2.7.2 question
If I forget to close SDR 2.7.2 before turning power off the Flexradio 1500, the next time I try to open Power SDR it doesn't open and a box appears offering me either Flexradio 1500 or Demo, but neither works. I have to restart the computer, which is a bit of a pain. Has anybody found a quick fix? 73 David, G4YTL ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz
[Flexradio] Out of band transmission
I fear I've just made a big mistake. I've been using a SDR1000 for several years as an IF for VHF transverter use. I decided to upgrade to a Flex-1500 which is of course apparently better designed for the purpose. But only now that I've spent the money have I realised the major problem. My 70MHz transverter uses a 50MHz LO (10Mhz source x 5) and an IF of 20-21MHz. I set up the Flex-1500 with ease, only to find that when I try to transmit I get an out-of-band message, because of course 20MHz is not an amateur band. I've seen some previous posting suggesting that an answer might be forthcoming, but haven't seen it. Have I wasted my money? Help please.

Enter any frequency in the band: it works. - Go back to HF using the HF button: if you enter any frequency either using the keyboard, the mouse of the band's buttons you get the exception index out matrix bounds or something close (I'm using a localized version of windows, so the message is in the localized language). - Also while in VHF, if I enter a HF frequency in the keyboard, it gives the same exception instead of going directly to the corresponding HF band.

[Flexradio] Odd transmit delay
I've just realised some bizarre behaviour of the X2TR if the X2 delay is set to 50 I use a SDR1000 with Power SDR v1.18.6. I use 20-21MHz output to drive a 70MHz transverter. Since inception I've noted a delay of about 0.5 seconds from pressing the PTT (on SSB) and getting transmit output and the Panadapter display changing. It's annoying but I just thought it was a quirk of the software. The X2 delay was set at 50 which is the default value and I'd never changed it before. By chance I've found that if the value is set to 49 or 51 (or indeed any higher or lower values) the delay on transmit disappears! Would be interested to know if anybody has seen this quirk. 73 David, G4YTL ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/

Re: [Flexradio] 144 and 432 - Low vs High Power Design
I suggest that there are two important issues to consider: 1) Power output. I have a strong preference for 50-60 watts - that allows driving of a 13db triode to 1kw. Intermediate amplifiers are undesirable. 2) Stability - for digital modes standard crystal oscillators are not stable enough. I would favour the approach used by DB6NT in their latest transverters - the ability to lock to an external source (eg 10MHz) - as an aside, can the 5000A, like the SDR-1000, be fed by an external frequency source? 73 David, G4YTL John [EMAIL PROTECTED] 01/07/2008 19:15 I have received quite a few emails [direct and via the reflector] regarding the subject above.

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] Hiccups in digimodes
I wrote previously about a problem using digimodes - specifically using WSJT with the SDR1K using VAC4.07. On transmit, I had hiccups, to coin a phrase used by Jerry - it took the form of brief drop-outs, lasting tens of milliseconds. I subsequently realised that the same thing was also happening on receive, with mutiple short drop-outs during each 30 second receive period. Two solutions were suggested, but neither worked for me (using VAC4.04 instead of 4.07, and changing SR from 11025 to 48000). But I have found the answer! It involves changing the clock offset in the VAC Control Panel. On transmit I have got rid of the hiccups completely by changing the offset for the relevant virtual cable to 1.010. On receive I have reduced the hiccups to only one or two per receive period by changing the offset to 1.008 - I haven't yet found a setting that eliminates the problem completely. Hope this helps somebody else! 73 David, G4YTL ___ 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] digimode problem
I am having a problem with digimodes and would appreciate comments. I am running a SDR-1K with DEM 144MHz transvwerter, which drives a 70MHz transverter. I am using WSJT v 5.9.7 and VAC4.07. When transmitting in any of the digimodes (i.e. FSK/JT6M/JT65) there are frequent, but brief (several tens of milliseconds), interuptions to the transmitted data stream. There is no problem when using SSB/FM/CW. So I am presuming this is something to do with VAC. I have tried altering the ms per int and clock corr with no effect. I can still communicate, but it's irritating. Has anybody else had a similar experience and found a solution? Just to follow-up a previous thread - I am delighted to say that I have thrown out the USB-parallel adaptor!!! I had no spare PCI slot but suddenly realised I had a PCIexpress X1 slot which now contains a parallel port. 73 David, G4YTL ___ 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] PCI express advice
I am being driven demented by the repeated daily dropping out of my USB-parallel adaptor. When I bought the SDR-1K I bought a new computer. If I'd known the problems I was going to have I'd have bought one with a parallel port, but I didn't. My Dell Dimension E521 has two PCI slots - one is used for the Delta soundcard and the other for a modem (we live in the Styx, can't get Broadband and so have to use dial-up!). I am therefore using USB and the adaptor. I have today fitted a powered USB hub, but the problem remains. I've just realised I've got a PCI-express x1 slot, and that parallel cards are available for that. I'm a computer illiterate and would appreciate advice as to whether that will solve my problem, or would I just be creating new ones. I am so fed-up with the USB-parallel adaptor problem that I'm on the verge of asking for my money back as the kit is not fit for purpose and it has seriously affected why earlier positive thoughts about Flexradio - especially as the latest version of Power SDR(Beta v1.9.1) won't even run with the wretched adaptor and nobody at Flexradio seems interested in solving that problem and producing new software. I'm blowed if I have to get another computer with a parallel port to solve the problem. I don't think my problems are all due to my computer illiteracy, but help and advice would be much appreciated. 73 David, G4YTL ___ 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] USB-parallel drop out.
I know that this issue has been raised before but would appreciate hearing peoples solutions. My PC (Dell E521) doesn't have a parallel port. It has only two PCI slots - one is used for a modem (we live too far away from the exchange and can't get Broadband so have dial-up!), the other for the Delta 44. So, I use the Flexradio supplied USB-parallel adaptor. It is a pain! Even when not using the computer for any other purpose, the adaptor may drop out. Power SDR then has to be shut down and restarted, and told the adaptor is in place. If you don't shut it down, but just go to Setup, it won't accept ticking the adaptor box. Any tips/tricks gratefully received. 73 David, G4YTL ___ 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] Beta 1.9 and USB
I guess I'm being stupid again but: I've installed beta 1.9. I've re-run USBIO. When I go to Startup and tell it the USB adapter is present I get an error message saying USB device not found (-4). What I am doing wrong this time!? 73 David, G4YTL ___ 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] Problem installing vCOM and VAC
I am having a problem installing N8VB vCOM and VAC4.04. I am following the instructions from KM0T. I install vCOM and VAC without any problem. When I go into Setup of PowerSDR the system crashes and I get a form of blue screen of death telling me amongst other things that: DRIVER_IRQL_NOT_LESS_OR_EQUAL I have tried various combinations of pairs of ports but same outcome. E.G. I used the pairs 14/24 and 15/25 to make sure I wasn't clashing with any others. I suspect that the problem relates to other software clashes. I am using the USB-Parallel adaptor with the SDR 1000 and also a USB to serial converter to COM 5 (for a GPS receiver) and a USB to serial converter to COM 6 (for PTT with WSJT) Computer is a Dell Dimension E521 with Duo core and 2Gb memory. As usual with computer problems, I am presuming it is my stupidity, but would value help and advice. 73 David, G4YTL ___ 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] Transverters (again!)
I still haven't resolved my problem despite Eric's help. I have an SDR1K with a built-in DEM 144MHz transverter. I use the output of the 144 transverter to drive a 144MHz to 70MHz transverter. So, I click on the 2 button of the Band Selection buttons, and the second transverter inputs/outputs at 70MHz. Happiness, but the SDR display shows 144MHz. What I want is to set up a Band button labelled 70, and when I click on it the DEM transverter is activated and the SDR display shows 70MHz. I have not been able to achieve this through the XVTR Setup option - which as far as I can see only works when using the HF output of the SDR. Sorry for the bandwidth, but any comments would be appreciated. Web sites such as that of KM0T don't help, as he is using the HF output to drive external transverters. 73 David, G4YTL ___ 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 Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/
[Flexradio] Transverters
I have been used to getting a reply to my queries within seconds from the ever-helpful Flexers. The fact I haven't had a reply to my last query makes me fear I've asked a very stupid question! I'd appreciate a comment in response to the following: Having had fun playing with my SDR-1000 with 1 watt on HF, it's now time to get it tamed for VHF work, which was the object of my purchase. I have the 144MHz DEM transverter installed. I will be using that to drive transverters for other VHF/UHF bands. If, for example, I am using a 144-1296 transverter, I presume I have to click on the 2 metre button and with the 144-1296 transverter connected to the 144 connections will be QRV on 1296. is it possible to get the display to show 1296 rather than 144? As far as I can tell, the XVTR Setup only works when using an HF signal to drive the transverter from the HF output of the SDR, or am I missing something? 73 David, G4YTL ___ 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 Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/

[Flexradio] OCXO
Does anyone have any experience using Isotemp 10MHz OCXO 1PPB EFC For GPS Discipline 12V with the SDR-1000? I see such units available on e-bay and they would seem to be suitable. 73 David, G4YTL ___ 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 Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/
[Flexradio] 70MHz operation
I would like to try my SDR-1000 on 70MHz - a band available to us in Europe. It seems to recieve - but I haven't looked at sensitivity. It won't transmit because it is not an IARU band - it is in Europe. Any comments/advice would be much appreciated. 73 David, G4YTL ___ 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 Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/
[Flexradio] 144-28FRS Problem
I apologise in advance for this posting, and realise I should wait until tomorrow to discuss with the supplier, but my impatience to get going got the better of me! I took delivery of a SDR-1000 (1 watt version) a few days ago and am up and running on HF. The suppliers (Waters and Stanton - who have given excellent service) installed the 144-28FRS. I can not hear anything through it, or get any 144MHz RF out of it. I appreciate that a likely possibility is that I am doing something wrong, but can't see what that is. I will check with WS tomorrow that they tested it live before dispatch, and just possibly there is a hardware problem. On Set-up I've told it that the transverter is installed. On XVTRs I have enabled the first line, UCB 0, Button text 144, LO offset 116.0, LO error 0, Begin Freq 144, End Freq 146, Rx gain 0. When I transmit the signal meter says there is power output, but there is nothing on 144MHz - but there is output at 28MHz on the appropriate frequency from the QRP socket. I am using the Parallel-USB converter.

[Flexradio] 144-28FRS - problem solved
Sorry for the bandwidth - problem solved! It was a hardware fault - a duff power connection to the transverter board. Now all functioning Ok. 73 David, G4YTL ___ 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 Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/
[Flexradio] Computer requirements
Several people have kindly offered advice with respect to my previous query about the use of duo core processors - I was concerned that such a processor running at 1.88GHz would be a poorer option than a single processor running at 3GHz. I'd have to say that the advice was a bit conflicting but I think either would be OK - but make sure you have plenty of memory. I was also advised by Flexradio to use Windows XP Pro or Home Edition, but to avoid XP Media. So now a further question, for which I guess there is not yet an answer, is what about Windows Vista? I need to take the plunge and replace my computer, so any comments will be received most gratefully. 73 David, G4YTL ___ 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 Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/
