Re: [Flexradio] Software Defined Vector Network Analyzer
One fly in the ointment ... the SDR 1000 hardware is not full duplex. So you can't measure the response to the signal your sending into the device under test.

[Flexradio] Software Defined Vector Network Analyzer
Hi Everyone, It appears to me that it would be principally only a little software to turn the SDR-1000 into a quality Vector Network Analyzer similar to the N2PK VNA http://users.adelphia.net/~n2pk/VNA/VNAarch.html only using the 11 KHz IF. I have got to build my homemade SDR-1000 before I can try this, but some of you with one already available to play with should try it. It requires running the transmitter at low power (probably using one watt or less and a step attenuator would be a good idea), and receiving the signal from a reflection bridge (for S11 or S22) or through a network (for S12 or S21). You will need to have a known 50 ohm load, and a good short and open to calibrate the measurements. I suggest saving the magnitude and phase of the received signal to a file so you can massage and display it in Scilab or Octave. I would be happy to offer help and suggestions and Scilab or Octave help to anyone interested in this project. 73, Rob, KL7NA -- Rob Frohne, Ph.D., P.E. E.F.

[Flexradio] Missing Messages
We have received several notices from folks that were subscribed to our mailing list that were not receiving the latest messages (as compared to the archives). I just went through the entire 666 member list and found many more people than I would have expected that had their "no mail" set to [B]. According to the mailman software that runs our list, this means, "Delivery was disabled by the system due to excessive bouncing from the member's address." While I would expect a few of these...maybe in the 10s for our size reflector, I found over 200. I suspect this is a result of a recent server move for our reflector which took place this past week. S... If this is the first message you have received from the [Flexradio] list in a while, welcome back and sorry for the interruption. Check the archive to see what you missed. I'll be watching to make sure this phenomenon does not continue. Have a great weekend and remember that tomorrow is Mother's day. ;) Eric Wachsmann FlexRadio Systems ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
[Flexradio] HPSDR project - resources: list, website, wiki
Most on this list are aware there is a group called HPSDR (High Performance Software Defined Radio) and many are part of that activity. The genesis of the group were a few SDR-1000 owners and some of the early communication was conducted on this Flex discussion list. Back in December, we started a discussion list specifically for the group (then known as the Xylo-SDR group) to take the traffic off this list. We have also taken advantage of the forums provided by Dale at hamsdr.com. In early March, the group name was changed to the present HPSDR and a website established to supplement the discussion list and forum. Now a wiki has been added to provide deeper detail and latest information. If you have an interest in this group, there are multiple ways of finding out what the group is all about and what it is "up to"... 1. Website: http://hpsdr.org - provides a good overview of the project and its modules. It is kept fairly well up to date and should suffice for the more casual interest. 2. Wiki: http://hpsdr.org/wiki/index.php?title=HpsdrWiki:Community_Portal At the moment, several project developers have edit access and have updated the wiki information to reflect "near current" status. This would be a good resource for those who would like more detail and cutting edge news than the website provides. 3. Discussion List: http://hpsdr.org/reflector.html to sign up or http://lists.hpsdr.org/pipermail/hpsdr-hpsdr.org/ to just read the archives. Traffic on the list has varied from less than one message per day to a recent high in the 60's! This is the way to participate in the designs or to keep up on the very latest directions. 4. HAMSDR.COM: there are some postings here, but more importantly, this is the place to sign up to buy any PC boards produced. But please read about the boards on our website hpsdr.org and ask questions on the hpsdr discussion list. 5. Teamspeak: same channel as the sessions held for the SDR-1000, and in fact HPSDR project is often discussed on the Friday evening (USA time) weekly session. Separate HPSDR sessions are sometimes held. This is an extremely exciting time and project. Thank you for reading this information and if you're interested, try one or more of the resources mentioned above.

[Flexradio] Image rejection?
Hi all, I'm evaluating my rig on the bench with a sig gen and have a few questions regarding image rejection... I am finding that the image rejection is not consistent from band to band. I can optimize on each band with a different set of values. Is this normal? It would be nice to be able to store seperate values for each band if so. My offsets are: ... 60m40m20m...15m...10m phase...-.89.-1.11...-2.08...0.02...-5.44 gain. 6.8.7.05.5.14...6.61...19.33 How much image rejection should I expect? I'm adusting it by tuning the sig gen to the image frequency and then nulling the received signal. I can acheive >70dB null. This is not the optimum for the observed image on the panadapter screen when tuned to the wanted signal - it is only ~ 60dB down. Also, I have a noise spike in the center of the panadapter (corresponding to DC). Its level bounces and it is at a reported ~ -80dBm to -115dBm depending on the preamp gain setting. I susspect this is AC 60Hz hum getting into the IQ audio. Is this normal? When I play the wave files from the flex site I do not see this which makes me susspect a ground loop or something.

Re: [Flexradio] new calibration when start. v1.6.1 first time ?
This is FFTW Wisdom. It has existed in the program directory for quite some time, but we added code that attempts to run it if the wisdom file is not found. This wisdom file optimizes FFTW for use with your particular system dynamics. It is a one time operation (per version) and should not take more than 3-4 minutes.

[Flexradio] SDRBreadboard up and running
Hello all, Well I installed Bob Cowdery's version 4 of the Squeak SDR Breadboard and after a double take (the original install file was missing a component so that the radio did not build correctly, but Bob has corrected that now), my SDR-1000 plays Squeak QSOs (no pun intended). Boy, this is different and fun all in one and one cannot help admire all the amazing work Bob has done. I will admit that I was slightly ahead of the game as over several weeks in April I decided to give Squeak a whirl, which started a regular back and forth email with Bob. He helped me ultimately get it all working (that was back in the days when the installation instructions were much more rudimentary than they are now) and together we worked on getting it to work with the RFE board and the Delta-44 sound card. Bob would do all the programming (my programming skills are limited at best) and I would feed back the results, as he still only has the original three-board stack at this point. What I can say, and this may help others, is that it took me a while to figure out the difference between Squeak and other applications. Usually under windows, when you double click on a file created by an application, windows will automatically start up that application and then open the file. You can of course instruct windows to start up Squeak when you double click on a Squeak image (image is Squeak speak for everything you have running under Squeak at that point in time) and all will appear OK, ie Squeak starts and image is displayed, but nothing will work. What you need to do is when you've installed Squeak, copy the whole directory in which the Squeak application resides to a new directory (let's call it folder 2). Start Squeak, build an image (by loading files into squeak, or installing applications, or anything else) and save it to that same directory. Next time you want to start up that image, drag it over the Squeak.exe icon in the same folder and all will work. More specifically, open folder 2, start Squeak.exe and when you have gone through all the many preliminary SDRBreadboard installation steps necessary and described on Bob's website, save the image (in a blank space click and select save as...Save it in the same directory (folder 2) from where you opened Squeak. This will be your back-up so that you will not need to go through all those installation steps again. Close Squeak and copy the whole folder 2 directory containing Squeak and the image you just built to a new directory (folder 3). Folder 2 will now always be your back-up. Open folder 3, drag the image you just created over Squeak.exe (both in folder 3) and continue to install SDRBreadboard. After you have installed SDRBreadboard, again save the image, but under a different name. (you will now have 2 images in your Squeak working directory: the pristine, base image you created earlier and the SDRBreadboard image, as well as Squeak.exe). To start SDRBreadboard in future, open folder 3 and drag the SDRBreadboard image over Squeak.exe and all should work. I hope this helps. I know it sounds confusing (believe me I was for a long time!) and it does take some getting used to, but when it does all work is a lot of fun. 73 de Joe - AB1DO Configuration: Dell Dimension 4700 /w 3GHz P4 HT + 1GB DDR2 SDRAM + Intel 915G Express + XPHomeSP2 SDR-1000 + RFE + 100W PA + USB Adapter Delta-44 + Break-out kit -- next part -- An HTML attachment was scrubbed...

I plan to demo my SDR-1000 at some ham clubs here in RI. and the presentations would be very nice to summarize.

Re: [Flexradio] Hamvention Activities.
Folks I am going to try to audio record the forums at Hara, but no guarantee on that at this point. If someone out there, planning to attend Gerald's and Our SDR forums at Hara would volunteer to record the audio, it would be appreciated. I will be 'broadcasting' all of the Festivities at the Suite on Saturday evening on Teamspeak, since they do have high speed Internet. The audio portions of the presentations by Gerald et.al. from the suite will be recorded and posted on Dale's website for later listening, possibly as late as the following Monday. I can't wait to see the new rig, even if only in prototype.

[Flexradio] new calibration when start. v1.6.1 first time ?
Hi! When I started v1.6.1 for the first time a DOS windows run some calibration for several min before any other screen. What was that? Have not seen that before. Could not see anything in the release rev. about it. rgds Kjell la6xj ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
[Flexradio] Teamspeak Audio - 05-13-06 lots of announcements
Folks No summary again, probably won't be one till after Fredrichasfen in June! In my announcements I refered to "USB" board, and actually I meant to say UCB board. I will not be on the Friday Forum next week. Will be at Dayton and all the festivities. I will be broadcasting Teamspeak Live from the From the Flex-Radio Suite next Saturday at utc. (and before). Join us live from Dayton. I also hope to have a Vidio feed and will post more details later in the week. More like SSTV than live television. Will have a Teamspeak - HPSDR meeting tonight just for general discussion of all the exciting HPSDR happenings in this week! If you have not ordered an Atlas board please visit Dale's hamsdr.com website in the projects section. We have 186 orders to date. I have delayed production a few days, but they will be available shortly and prior to the other project boards.

[Flexradio] ptt problem
does anyone have a copy of the instructions to change R9 from 1k to 470 ohms to correct the occasional problem where the equipment does not go back to receive? I need the location of the resistor and which board it is on also.
