[linrad]
Hello, All, There are now two versions of the XLinrad Debian Archive file: xlinrad is now 'stock' xlinrad without my addons [a change] xlinrad-1000 is xlinrad plus the FT1000MP controller plus the LO offset functions for weak signal work [was xlinrad before this change] Both were compiled for i386 using Leif's version 02.17. Installation instructions are still at: http://www.nitehawk.com/w3sz/xlinrad-deb.htm Problems? Let me know and we'll do our best to fix them. 73, Roger W3SZ Roger Rehr W3SZ http://www.nitehawk.com/w3sz # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] changed repository address for xlinrad Debian Archive file
Hi, All, I have changed the structure of the Debian Archive Repository for the xlinrad file slightly. This was done so that users can, using the same single line added to /etc/apt/sources.list: 1. download versions for multiple architectures as they become available 2. download multiple programs in addition to Linrad [e.g. other dsp programs] The line that should be added to the /etc/apt/sources.list file on your computer is now: deb http://www.nitehawk.com/w3sz/debs etch main non-free contrib All other instructions remain the same. 73, Roger Rehr W3SZ http://www.nitehawk.com/w3sz # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: xlinrad.deb file makes things simple to run
Hi Sergio, Thanks for the note! OK, now I understand what you meant. Sorry for being so dense here. I boot directly into X-Windows so I never get a chance to [never need to is another way of saying this] tupe 'sudo' before typing 'startx'. Linux is perfectly happy to boot directly into XWindows even for a regular user. It is clear that different versions of linux behave differently, and I don't have enough experience to know what is 'usual' and what is 'unusual' in what I see here ;) Ubuntu Linux boots directly to XWindows environment even for a simple user. That is what it does in its standard form. It won't even ALLOW root to log in directly to XWindows, although that is easy to change and I have done so here. Here, when I boot directly into Ubuntu XWindows with a regular user account, I can start to run Linrad without doing sudo and I can even see all of the xwindows linrad screens OK without doing sudo. But I don't get any spectrum or audio. Running linrad as suggested, with 'sudo linrad' gives me the audio and everything runs fine. So for me not being sudo does not keep me out of X Windows, and it does not keep me out of the XWindows Linrad screens. But not being sudo does prevent Linrad from working properly. In exploring all of this I did find out something interesting that would only affect those trying to run Linrad as multiple different users on the same machine. This has nothing to do with whether you are running Linrad va the standard install from a tarball and then having compiled on your own machine or whether you used the debian archive to install it. It is the same either way. I have verified that it is identical on the systems here where I installed Linrad the 'old fashioned way' as well as via the xlinrad.deb file. When it writes the par files do disk, Linrad sets the permissions on all of the par files so that only the owner can write to them. So only the user who originally ran Linrad from a given directory and set up the parameters can run Linrad on that machine from that directory. Anyone else must do one of two things: run it from another directory where a new set of par files will be generated, or changed the permissions on the par files. To keep disk clutter to a minimum, I set up the xlinrad.deb archive so that all xlinrad activity occurs in the directory /usr/xlinrad. So if you are running Linrad as installed from the xlinrad package, if several different users each try to use Linrad [at different times] on the same machine, only the original user, the one who made the par files, will be able to use Linrad by typing 'linrad'. The others will not be able to access the files. As just noted, there are two ways around this: [1] I got around this by going, as the owner, to /usr/xlinrad and doing: chmod 666 * chmod 777 linrad chmod 777 xlinrad This allows anyone to read or write to all files, and in addition allows anyone to execute the linrad script and xlinrad, which it invokes. One could also just copy xlinrad to another directory and run it by typing ./xlinrad and things would work fine. Your par files would then be written to whatever directory you were working from. 73, Roger W3SZ Sergio writes: Hello Roger, very good. As I said I wasn't a 'sudoer' (hi, it sounds like being a bit strange person, hey I am a sudoer now...what?) and I always access as a standard user. So just by typing su - and password and launching linrad one can still get stuck with the software being unable to drive the screen properly. That can be solved by giving the proper rights of access to the screen but a rookie might have some problems to do it. That's why I dropped the little suggestion to cut short and go for 'sudo'. Surely if one starts the X session as root he/she won't even notice that. Hey I am your user now, please keep the package updated... hihi just kidding of course, but I truly wish you'd like to do so in the future. Great idea. Installing linrad now it is even easier than the windows version... 73s Sergio w3sz wrote: Hi, Sergio, Thanks for the kind note! I am very glad things are working for you.

[linrad] Re: xlinrad.deb file makes things simple to run
Hi, Sergio, Thanks for the kind note! I am very glad things are working for you. Enjoy Leif's great piece of software! The instructions did say: Just type 'linrad' [linrad' [or 'sudo linrad' if you are not root] I think what you are saying is that you forgot to say 'sudo' each time,and sudo only works for one command. You are right. There is a better way. If you type 'su' instead of sudo, that should ask you for password and then after you give it, allow you super-user privileges in that terminal window until you shut down that terminal window. I run everything as root and so I 'forget' all of this stuff until someone reminds me of it. I apologize for not giving the 'su' alternative. I didn't try it, buy I think it should work fine. If so, you would just need to enter 'su' and password at the beginning of your terminal session and then you would stay a super user. By the Way, Kubuntu works differently, I have read. If you do 'sudo' it asks you for a password and then allows you to be super-user until the terminal window has been idle for some defined period of time. Thanks again, and Have Fun! Let me know if there are any problems. Ubuntu and this Debian file make getting started with Linrad far easier than with the old Knoppix Live CD I had placed on the web last year. That is why I removed the Knoppix Live CD from access. It would now lead one down an inferior, more troublesome path. 73, Roger W3SZ Sergio writes: Dear Roger, being a Debianeer only I tried your package and it works like a charm, I still have to go in deep details but the package is alive and running. This is on an old native sarge installation on a desktop machine but I also tried on a current testing version running on a laptop windows machine under vmware... just fine. The only comment I would add to your procedure it is about the fact that it is very recommendable to install 'sudo' and thus become a 'sudoer' for linrad purposes. I wasn't one of those and I initially got some troubles because simply typing linrad from superuser prompt would cause me an error in driving the screen interface, which is a very common one. I knew what it was so I cutted it very short by installing sudo. Very rookie suggestion but better than nothing I guess.

Type 'U' to setup the soundcards. You will get some very helpful information in green at the right of your screen. It tells you what number to enter to select your input and output sound devices. 10. As usual, follow the prompts. First enter the input device. For me with my Delta44 in 1/2 this is a '4'. But this won't necessarily be your number. Just follow the green information as it makes this easy. After you have typed the number, hit 'Enter' as usual. 11. For a 'standard' I/Q receiver, type '2' on the next screen that asks you to select the radio interface. Then hit 'Enter', as always. 12. On the next screen you are asked to enter the sampling rate. For the Delta 44 I enter 96000. Your soundcard manual will tell you the highest value you can enter. 13. On the next screen, select your A/D data format. For most devices this will be '1', for 16 bits. For the Delta44 you can select '2', for 32 bits. That is what I choose. On This one you don't need to hit 'Enter'. 14. On the next screen, use the green information to select your output sound device. For me, this is the onboard sound, which is '0'. Again, let the green print be your guide. Hit 'Enter'. 15. On the next screen, I say 'N' for use close and reopen. 16. The next screen shows you your choices. 'press any key' and you will be brought back to the main menu. 17. TYPE 'W' TO SAVE THESE PARAMETERS. Now you are ready to start the receiver. You will have [too] many choices on the following screens for a newbie. Do what I do. Just hit 'Enter' at each screen and accept the defaults in the next steps. 18. Pick a mode by typing the appropriate letter on the main screen. I usually play with 'A' for weak signal CW or 'D' for SSB. It doesn't matter which of these two you pick. Lets say you type 'D'... 19. Now you will start seeing the parameter screens. Read these if you like as you go thru them, but I recommend that you hit...Enter...Enter...Enter...Enter...Enter...Enter until you come to the receiver screen. 20. You can move and resize the various windows by pulling on their edges. 21. You can receive a signal by clicking on it in the main waterfall or main spectrum or in the red-lined high resolution spectrum. 21. You can't click on the signal in the filter window [green lines, yellow filter, red bfo-frequency lines], but you can change the filter shape
[linrad] Re: xlinrad.deb file makes things simple to run
Hello, All, I should have made two 'assumptions' clear in my post on xlinrad.deb. 1. You need to have X-Windows installed and running and to be in the X environment to run xlinrad. 2. You need to have a sound driver [ alsa, oss, etc] installed and running to run xlinrad. If you are using stock sound it will likely be running automatically. If you are running oss you may need to start it manually.

[linrad] WSE Controller GUI
HI, All, Linrad does a great job of controlling the WSE hardware, and there is no need for any other program for controlling the WSE hardware when in Linux. Nevertheless, just for fun and as an excuse to play with QT 3, I decided to make a little C++ based GUI to control the WSE units in Linux. I use it when playing with the WSE units and DttSP. For those of you who also have WSE units, I put a tar.gz file with the source and executable [which is called 'test' as I forgot to give it a nice name before making the tarball] on the web at: http://www.nitehawk.com/w3sz/WSEControlinuxl.htm It is basically just a minor rewrite of the Visual Basic program I wrote to do the same thing in the Windows XP environment. That Visual Basic software is at: http://www.nitehawk.com/w3sz/WSEControl.htm Linrad is of course still my favorite, but it is fun to play with new toys! I am not a programmer, so I am sure the code is ugly, but it works here and I learned a bit doing the project ;) I am always happy to learn and hear suggestions. 73, Roger W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: Ubuntu and Linrad
Hello, All, Ubuntu installed painlessly except as noted below. I downloaded a Ubuntu iso and made a CD. After booting from that I just clicked on 'install' and it installed it on my hard drive. Linrad works fine with Ubuntu [and did so right from the start]. There werea few interesting facets of Ubuntu installation: 1. It will not let root sign in to the gnome login screen until you change the default parameters to permit this. 2. It does not automatically activate the root user. This must be done manually. 3. If you do sign on as root by going thru a terminal mode signon and then create a new user, you won't be able to enter the gui [Gnome] as that user because the home directory was not created by that user, but by root and this breaks the rules. So if you don't set up a second user on the initial install, because you are planning to just use root, you will be unhappy. Also, Ubuntu does not come with 'make' installed!!! You need to install it via apt-get or synaptic. You will want to broaden the repositories for these, too. There is a nice 'unofficial Ubuntu guide' that has lots of good information. Also, Ubuntu does not come with gcc installed. Again, you need to get it with apt-get or synaptic. As usual with svgalib, the svgalib_helper error crops up. I get around this by setting [uncommenting] NO_HELPER in the /etc/vga/libvga.config file. 'mdev /dev/psaux' is needed in that file too. Linrad ran on the first try with the stock sound. NO issues at all. As usual, the issues noted above are not LINRAD issues, but LINUX issues. Fortunately, these are pretty minimal with Ubuntu, being primarily limited to my stupidity in figuring I was just going to be root user [Had I RTFM, this 'issue' was well detailed there and depicted as a major plus, from a security point of view]. PS...in his install notes, Leif had as a step: 'wajig recommended xlibs-static-dev' for X11 compilation. This file is now deprecated. Rather than try without it [which would likely have been the smart thing to do], I just wajig'd all of the files that wajig listed as being newer substitutes, and xlinrad compiled and ran fine the first time after I did this. But I didn't try to compile without downloading these files, which would have been smart and would have saved about 5 minutes. Linrad.exe also compiled right off the bat. All in all, a pretty painless install! 73, Roger W3SZ On Wed, 02 Aug 2006 18:07:39 -0400, [EMAIL PROTECTED] wrote: Hello, All, I am converting my last remaining RedHat Computer to another distro, as I need to install some 'new' files so I can play with dttsp on that computer, and its too much of a pain to get these files installed and set up in a very old [pre-Fedora] version of Red Hat Linux due to tye usual Linux dependency issues.

[linrad] removing knoppix files /instructions from web
Hello, All, The Ubuntu Linrad installation is so problem-free that I think there is no need to maintain the Knoppix Linrad Live CD repository/ instructions that I had placed on the net anymore. In fact, given that at this point the Knoppix version I used seems more problematic than Ubuntu, I think anyone who stumbled into those files might be himdered instaed of helped. So I will plan to start deleting all of that stuff tomorrow unless someone has strong feelings otherwise. 73, Roger Rehr W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] email woes
Hi, Leif et al, Comcast is again not letting my email thru to Leif's email address. I have no problems with any other email address that I have ever tried. I am hoping one of the gurus on the list can help me with this problem that has been intermittently occuring for at least 6 months, perhaps as long as a year. This weekend it is persistent and hence this email, which is a call for help with the problem. Here is the header of an email from Leif to me, as I see it on the Comcast Webmail page: Received: from smtp-2.calypso.net (bas19.calypso.net[82.117.97.84](misconfigured sender)) by rwcrmxc24.comcast.net (rwcrmxc24) with ESMTP id 20060506151649r24005u5gue; Sat, 6 May 2006 15:16:59 + X-Originating-IP: [82.117.97.84] Received: from etch.JADER (82-117-121-225.tcdsl.calypso.net [82.117.121.225] (may be forged)) by smtp-2.calypso.net (8.13.1/8.13.1) with SMTP id k46FGcMN068450 for [EMAIL PROTECTED]; Sat, 6 May 2006 17:16:47 +0200 (CEST) (envelope-from [EMAIL PROTECTED]) Date: Sat, 6 May 2006 17:11:52 +0200 - Here is the header of the error message I get back from Comcast when trying to send an email to Leif using the Webmail feature of Comcast. I am doing this instead of using Opera or Outlook because it has seemed that SOMETIMES I can get something thru using Webmail when these 2 programs fail. I suspect that is an illusion, though, due to the erratic nature of the problem. I have had an intermittent problem getting email to Leif [and ONLY to Leif] for at least 6 months. Comcast says everything is OK at their end and there is no reason I should be getting these messages or having the email blocked. Here is the header from the automatically generated Comcast Postmaster's message to me about the emails I am sending to Leif that don't get thru: Received: from rmailcenter06.comcast.net ([204.127.197.116]) by comcast.net (rwcrmhc13) with SMTP id 20060506165625m1300pek8se; Sat, 6 May 2006 16:56:25 + From: [EMAIL PROTECTED] (Webmail Postmaster) To: [EMAIL PROTECTED] Subject: Returned mail: User unknown Date: Sat, 06 May 2006 16:56:25 GMT X-Mailer: Webmail sendsmtp (Compiled: Aug 13 2002) X-Authenticated-Sender: dzNzekBjb21jYXN0Lm5ldA== MIME-Version: 1.0 Content-Type: multipart/mixed; boundary=NextPart_SendSMTP_293fm934u9jlm4_14057_1146934585 --NextPart_SendSMTP_293fm934u9jlm4_14057_1146934585 Content-Type: text/plain Content-Transfer-Encoding: 8bit The following addresses had fatal errors: [EMAIL PROTECTED]: 550 [PERMFAIL] destination not valid within DNS --- Any thoughts, anyone?

When I was previously referred to the comcast abuse dept or whatever it is for help with this problem, they checked something and told me Leif's email address was 'ok' as far as they were concerned. Since smtp-2.calypso.net (bas19.calypso.net[82.117.97.84] is listed as being misconfigured and possibly forged, I wonder if [1] that is the mailer for Leif's ISP, and if [2] there is some configuration 'feature' of it that comcast's mailer doesn't like. Hoping for a guru's solution, I am now going outside to do some tower climbing ;) 73, Roger W3SZ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Fwd: Softrock as part of VHF receive chain
Hi, All, RE: the recent threads on using Softrocks as part of the receive chain; in the latest EME Newsletter for 432 and up it is noted that Dave Robinson, WW2R, is using a SoftRock 7 as part of his receive chain for 1296 MHz EME. Here is the post. I posted the whole thing so you can get a sense of things: WW2R: Dave [EMAIL PROTECTED] is now QRV on 13 cm as well as 23 cm - On 1 April I built a 13 cm VE4MA superfeed with tubing donated/shipped by PA3CSG - TNX. On 2 April I had a sked with VE6TA at 1700 but my DB6NT xverter broke twice. We eventually worked at 2000 for initial #1. During the week I changed preamps to a WD5AGO style and changed the relay/adaptors, lowering the system NF by 0.35 dB. On 8 April I operated the DUBUS contest. Exceptionally loud signals were heard and my echoes copied 2 dB over the noise. I worked OK1CA, F2TU, W5LUA and OK1KIR. CWNR were ES5PC and HB9JAW. On 9 April signals weaker and no echoes copied. OK1CA seemed down by 10 dB. I CWNR HB9SV, OE9ERC (2 hours) and SK0UX (1 hour). I also heard but did not QSO WA6PY. I did work OZ4MM (weaker) and G3LTF crossband on sked. Using my softrock 7 RX, I simultaneously monitored 2320 and 2304 all weekend. G3LTF was the only signal identified on 2320. I also listened on 2424 during JA window, but heard nothing. On 11 April I worked OE9ERC for initial #8 (17 dB over the noise) on a sked on both CW and SSB. Echoes were 1 dB over the noise at this time. On 12 April I received nil on sked with NA4N, and heard WD5AGO on sked but did not complete. I have my 23 cm feed back in the dish in preparation for May contest activity. I have also stared work on a 3456 system. ---end of WW2R post- Its nice to see that the SoftRock 7 has been 'battle-tested' and is performing well ;) I got my SoftRocks for 160m and 80/40m yesterday and hope to put them together this weekend, though I have a few other chores that may prevent that. The v7's for 28 MHz should be shipped next week, I believe. I have emailed Bill Kelsey N8ET at Kanga USA and he has the LNA's for the R2 Pro in stock at $12 each plus $5 for shipping. I had previously posted his URL, and his URL lists his email address for those interested.

[linrad] Re: Fwd: [softrock40] Ver 7 28Mhz preamp? Yes
This looks very nice, Gian! As an inexpensive and easy-to-obtain choice, I have used the LNA module, set up for 28 MHz, from the R2Pro by KK7B. It is available from Kanga Kits. http://www.bright.net/~kanga/kanga/KK7B/r2pro.htm here in the USA. It is only $12. I have a couple of them in use at my shack in front of my RF-to-baseband converters [not SoftRocks yet...they should arrive soon] for a couple of years and they seem to work well also.

I would suggest to add the W7AAZ preamplifier using 4xJfet in parallel, as used in the CDG2000 and Pic-A-STAR. This preamplifier has a very low noise (expected below 2dB)and another important aspect: The output impedance changes are no reflected to the input like for the Norton amplifier. It also has a high IIP3 (+35dBm).

[linrad] Re: Fwd: [softrock40] v7.0 kit run or not?
Hi, Josh, I am not an RF expert, so take ANYTHING I say with a large grain of salt. I was waiting for the real experts to chime in, but haven't seen any answers from them, so here goes ;) The site you found and listed in your email looks good. Thanks! If you have a preamp for the band you want to play with [lets say 144 MHz], you could make something VERY simple with just the preamp as the front end, a Minicircuits TUF-1 mixer, and an LO at 116 MHz. If the preamp had selectivity, you wouldn't have a problem with the image frequency. If needed, you could put additional simple gain stages before or after the TUF-1, but trying it without those would get you started. Hope that helps. I can't wait for the SoftRocks to arrive here! Don't forget to play with Rocky! http://www.dxatlas.com/rocky/ 73, Roger W3SZ On Tue, 25 Apr 2006 12:51:29 -0400, Josh Logan [EMAIL PROTECTED] wrote: Hi Roger and everyone.

[linrad] transverters and homebrew receive chains
Hi, Josh, Just a brief additional note with some more info. I wrote last night's post very late and well past my bedtime, so it was short on practical detail to help you get started, which is I think what you want. I apologize if this is too basic or not what you wanted. If that is the case, please let me know. I would again recommend as I did in my previous email that you start with a preamp [tower-mounted] for the band you want [144 MHz, for example], followed by a TUF-1 Mixer [for example], an LO at 116 MHz [for example, for 144 MHz RF input, of course], and then the SoftRock 7.0 as a 'get started' system. The TUF-1 and the 116 MHz LO will of course convert the 144 MHz input signal to 28 MHz, suitable for input into the SoftRock 7.0. I use SSB Electronics Preamps for Terrestrial work on all bands thru 1296, and DEM for 2304 and 3456, and then DB6NT for 10 GHz and 24 GHz. So I can speak to the effectiveness of those particular devices. THEY WORK! http://www.ssbusa.com/gaasfet.html http://www.downeastmicrowave.com/ http://www.ssbusa.com/mku23.html http://www.ssbusa.com/mku24.html The SSB units have noise figures of 0.8-0.9 dB which is plenty good for terrestrial use. The DEM units are 0.7-0.8 dB. The DB6NT units are 0.7 dB on 10G and 2.0 dB on 24G. I have used cavity-input preamps for 144 MHz EME; first KA0RYT design, and more recently [past 3 years] LNA Technology http://www.lnatechnology.com/ These units are spec'd to have NF 0.2 dB. You don't need that on 144 MHz for terrestrial use. The SSB Electronics Preamps have helical filter inputs and I did not have any problems with the image frequency during the several years that I used homebrew schemes such as this for both terrestrial and EME reception [before I got the WSE boxes]. From 2000-2004 a simple homebrew receiver of this type [different IFs and LO's due to my being limited by the parts I had on hand] was my 144 MHz EME receiver and it worked great, better than any commercial receiver I'd used, including my FT1000MP or Elecraft K2 with commercial transverters. That is because it had an excellent preamp with cavity filter in front of it, and Linrad behind it. While this did not use a SoftRock, the point is made that you can do very well with a SoftRock and what I am recommending, because the 'rear end' that I used was nothing as nice as the SoftRock, and yet I got excellent results! A schematic of this old system [which used conventional mixers, not I/Q mixers] is at: http://www.nitehawk.com/w3sz/w3szdspnew.htm#figure2 . You actually want figure 3, but this URL centers the schematic in my browser window here. If not, use http://www.nitehawk.com/w3sz/w3szdspnew.htm#figure3 . With most of the iterations I used I did not need additional amplification [beyond that provided by the preamp on the tower] before the TUF-1, but with some I did need such amplification to optimize overall system performance. If you know the noise figures and gains for the individual compnents in your system, you can calculate the expected system performance for these values, and you can play with these values and see what effect it has on overall system performance. Balancing system gain can pay off nicely with improved performance. As a non-RF guy I need simple formulas, and so I remember that the overall system Noise Temperature is equal to the sum of [the noise temperature of each stage divided by the products of the gains of the preceeding stages]. So T = T1 + T2/G1 + T3/[G1*G2] + T4/[G1*G2*G3] + etc. For Noise Factor this becomes F = F1 + [F2-1]/G1 + [F3-1]/[G1*G2] + [F4-1]/[G1*G2*G3] + etc. Noise Figure is just 10 * log[F]. Its also important to know whether you are sacrificing useful dynamic range with your choices. At this point the calculations get beyond what I want to do manually. Fortunately, the late/great HP had developed an excellent tool called AppCAD that has in its main menu a 'noise calc' function that lets you input the parameters for your system's various gain [loss] stages and play with the variables to see what effect this has on your overall system Gain/Noise Figure/Noise Temperature/MDS/IIP3/OIP3 etc. You can download it from: http://www.hp.woodshot.com/ It is highly recommended and lots of fun. I hope that helps! Please let us know how you make out! 73, Roger W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] WSE Control
Hello, All, I have put a 'finished' version of the Windows WSE Controller on the web at: http://www.nitehawk.com/w3sz/WSEControl.zip This ZIP file contains: WSEControl.exe , the Visual-Basic-derived .exe file inpout32.dll , the dll file to go in the windows systems directory, to allow printer port device control under Windows [necessary to use this program] hwinterface.ocx , an ocx file to be used if compiling your own programs to control parallel port with VB [though you need a few other files too] and the readme.txt file that came with the dll and other files in question. http://www.logix4u.net/inpout32.htm hs the dll and example files, etc. The WSE Controller controls the frequency of the WSE whether you are using the RXHFA HF module or the RX144 module as the front end, and allows you to listen to 160, 80, 40, 20 or 2 meters, or 10 MHz with the WSE hardware. I am also having fun listening to the bands using the WSE hardware with this controller and 'Rocky', a simple SDR with no frills. It is nice because it can exist as just a small window at the top of the Windows XP screen and I can listen to the bands while doing other things on the computer. Check it out at: http://www.dxatlas.com/rocky/ If you try my WSE Controller let me know how it works [or not] for you. Remember that you need to put the dll in the windows system directory. I suspect that you also need the usual VBRun files, but I haven't checked that out as ALL of the machines here already have them in place. 73, Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Delta44s
Hi, All, It turns out that the Delta44 driver has no problem with multiple Delta44s coexisting in the same box [just as mAudio indicated]. I found out this afternoon after I put 2 Delta44s into my 900 MHz P3 that when you open the Delta44 Windows driver interface window it has buttons that allow you to select either of the two cards and set the parameters for that card individually. With 2 Delta44s in the P3 box I was able to run separate instances of Linrad for MSWindows individually for each of the cards and thereby have individual Linrad screens for different sources of RF signal displayed simultaneously. Now its just a matter of rewiring the shack one more time to accomodate all of this ;) 73, Roger W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Fwd: [softrock40] SoftRock v7.0 production now scheduled
Hi, All, Below is a note from Tony Parks re:Softrock v7.0. I would suggest those interested get their money/notes to Tony fast as these will go very quickly! 73, Roger W3SZ Good Morning All, Response has been positive about a production run of two hundred v7.0 SoftRock kits with kit delivery starting May 8. This is the SoftRock version that uses the I7SWX/VK6APH mixer design to convert RF signals to I/Q audio output. The kit will include the PCB, and all parts on the board but not include any of the external wiring such as the stereo audio cable. Please see Bill's website, http://ewjt.com/kd5tfd/sdr1k-notebook/sr40/sr7/index.html, for a view of what the production v7.0 board will look like and his beta v7.0 performance measurements. Additionally, Bodo, DJ9CS, has posted in the Photos area of this website a PowerSDR screen shot of a beta v7.0 SoftRock running with a calibrated input signal. Circuit boards will go on order this morning and orders for some of the integrated circuits have already been placed. Parts that might have delayed kit shipments beyond May 8 were found in stock and have been ordered. I am trying to determine what crystal frequencies can be included with the kit to make the receiver most useful in the 10m IF application. Two crystals will be included in the kit, 28.224 MHz and a second frequency to be determined in the next few days. Feedback on what frequency would be most useful and/or a lead on where I could order that crystal would be very helpful. Additionally, if there is interest in using the v7.0 on one of the higher HF ham bands, I will be able to substitute a crystal for that band in place of the 10m crystals. PayPal orders may be placed starting today with payment directed to my e-mail address, raparks at ctcisp.com (put @ in for the word at). The v7.0 kit price will be $18 for US/Canada and $19 for DX with kit mailing cost included in the kit price. Payment may also be made by check or money order to me at: Tony Parks 1344 E 750 N Springport, IN 47386 USA Thanks and 73, Tony KB9YIG --- Forwarded message --- From: kb9yig [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [softrock40] SoftRock v7.0 production now scheduled Date: Fri, 21 Apr 2006 06:44:06 -0400 raparks at ctcisp.com -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] multiple instances of Linrad
Hi, All, The SoftRock v7s are so cheap I am starting to come up with all sorts of uses for them in conjunction with Linrad. One thing I had mentioned to Leif in the past was running multiple instances of Linrad so that one could watch simultaneously the 'bandscopes' of each of the lower VHF bands at all times during a contest. Now that X Windows and MSWindows versions of Linrad are available, it is easy to display two or more Linrad windows on the screen at the same time. With a Soft Rock dedicated to each of 50, 144, 222, and 432 MHz one would have things covered pretty well in terms of constant monitoring of the lower bands during a contest [or just looking for openings on each of the bands simultaneously at other non-contest times]. My thought is to have one computer and monitor dedictated to being this 'full time monitor' using 2 delta44's as inputs [each Delta44 could handle 2 SoftRock cards and therefore 2 bands], and the onboard sound for output, and constant simultaneous displays of the Linrad bandscopes for each of these 4 bands on the screen. With the appropriate selection of parameters [and the fact that for MONITORING you don't even need to be clicked on a signal most of the time] one should be able to run 4 instances of Linrad and not overtax the cpu. As I type this I am running two instances of Linrad with the Delta44 sending a different [I/Q] input to each and thus I am monitoring two different receive chains displayed in two different Linrad-for-Windows-Windows. Even when listening to both signals with 96000 Hz sampling the CPU is happy and I am not getting glitches [Windows XP, P4, 3.2 GHz, Linrad-02.6a]. So running 4 instances of Linrad at once with parameters chosen to minimize cpu overhead should be no problem. I put a screen grab of the two copies of Linrad running at the same time, much as they would be displayed in this application, for your amusement at: http://www.nitehawk.com/w3sz/twolinradsatonce.gif The only glitch that I forsee would be if two Delta44 cards installed at the same time are not handled properly by the OS. But mAudio's site says you can have up to 4 installed at the same time. If that is true, and if you had the cpu power...I will leave the math to you ;) I can't wait to get those SoftRocks! Its almost like free radio ;) Maybe I had too much caffeine today at work. Have a great weekend all, and 73, Roger Rehr W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: multiple instances of Linrad
Hi, Stan, Thanks for the note! You are right that this is too much fun ;) The way I have my hardware FT1000 control add-on written at this point only one instance of it could be open at a time. But it would be simple to rewrite it so that the serial port was only opened when the data link was to be used, and to close it immediately thereafter. If that were done, then I could use multiple instances of XWindows Linrad and still retain control of the FT1000 frequency from Linrad. Then I could forget about the separate computer for monitoring and just use one computer / monitor with 4 or 5 instances of Linrad running for everything. I will play with changing the code later today at Hilltop. Because Linrad for Windows won't control the FT1000, this all depends on XWindows-Linrad being as happy with multiple instances as Linrad for Windows is, and I haven't checked that out yet. Have a great weekend, and 73, Roger W3SZ Consider the other multichannel M audio PCI cards like the 6-6 or the 1010. I am not an expert on the mAudio cards, but I believe the 6-6 still only gives 4 analog channels of in/out. The 1010 appears to me to have bandpass filtering of the analog signals so that even though it samples at 96K, the spectrum is limited to 22 Hz-22kHz.

[linrad] Fwd: [softrock40] v7.0 kit run or not?
Hi, All, Bob mentioned this project in an email yesterday. It would make an EXCELLENT first entry into VHF and up SDR radio with an XXX to 28 MHz transverter in front of it and LInrad behind it. I plan to play with one using a PTS as the LO frequency standard instead of an xtal. At less than twenty USD you'd have to be crazy not to order one [or more] to play with. If you are interested, I'd suggest contacting Tony KB9YIG right now so you don't get locked out of the next kit run when it too is oversubscribed. You can get his address by going to the softrock40 yahoo list site and nosing around a bit, or by going to the softrock40 page that Bob listed yesterday. The URL for the Yahoo list is below... 73, Roger Rehr W3SZ --- Forwarded message --- From: kb9yig To: softrock40.at.yahoogroups.com.nospam Subject: [softrock40] v7.0 kit run or not? Date: Thu, 20 Apr 2006 15:38:29 -0400 Good Afternoon All, Not many have posted so far concerning the performance of the v7.0 SoftRock but I continue to get a number of inquiries concerning a kit run in the near future. Bodo's, DJ9CS, pictures posted 4/19 and data Bill, KD5TFD, has collected indicate the v7.0 should work nicely for its intended use as an IF for VHF/UHF converters. Also the v7.0 with a LNA daughter board could be a nice little receiver for some of the higher HF bands. A number of hams have ask in recent days concerning the availability of v7.0 kits. At this time I am down to just a few v7.0 kits to support built kit orders, but I am willing to do a kit run of 100 or 200 kits if there is enough interest. At about two hundred v7.0 kits the kit price will be $18 US/Canada and $19 for DX with the postage covered by the kit price. The kit would include the PCB and all components that go on the board but no external cables such as the stereo audio cable. Please let me know if you are interested in a SoftRock v7.0 kit.

[linrad] linrad 02.05 and Debian Etch
This is just a quick note to note that to my surprise here at Hilltop where I am running Debian Etch, XLinrad-02.05 runs fine with no glitches, no mouse-related-crashes, etc. I guess this was somewhat predictable since Leif had no problems at his site, but I was very surprised nonetheless. I did find that I couldn't 'make' xlinrad until I updated my packages and brought in some X11 header files, etc. I am not sure which change made it possible to compile, but anyway things are working. THe problem was that there was no X11/Xlib.h file present and so make failed before I did these things. Now /usr/X11R6/include/X11 contains the requisite files and all is well. So Debian Etch and xlinrad-02.05 work fine together here. I am running Debian Etch with kernel 2.6.15-1-486. My problems with Debian Sarge and xlinrad-02.05 have already been reported. So changing to Debian Etch makes a large difference: complete success with Etch vs major glitches with Sarge. 73, Roger W3SZ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: Linrad-02.05
Hi, Leif, Thanks for the reply! OK on CPU overload being the likely culprit. Just for documentation, I am running on the machine used for the tests I have reported: 3.2 GHz P4 1.5 GB RAM Debian Sarge Kernel 2.6.13 Xfree86 4.3.0.dfsg.1-14_i386 ati x driver PCI Express ATI RV370 (Radeon X300 PCI) videl card Gnome I did a test this am and found that as long as I don't move the mouse, Linrad runs fine. I ran Linrad for one hour and 43 minutes with a signal selected and everything remained fine. At one hour and 43 minutes I moved the mouse across the screen and within 5 seconds Linrad crashed with the error message: debian:/home/linrad/linrad-new/linrad-02-X11.05# ./xlinrad X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 0 () Serial number of failed request: 438343 Current serial number in output stream: 438354 THe first two lines of the X Error message are exactly what I see most of the time; the serial numbers change each time. This page on debugging X Window errors may help in figuring out how to track down what is going on with the X errors: http://www.rahul.net/kenton/perrors.html I can't pull the S meter away from the bottom left corner Try more times. It is difficult to find the right position with the arrow mouse. I do not know yet how to change to have a cross for the mouse. I will keep trying. I have pulled it about 50 times and it won't move. I was able to move all of the other windows, and the polarization angle control moved OK as well. I will go back and make the changes to parameters that you suggest, Leif. I just used the default parameters to start. Some change in how things are done may be needed given that the CPU overload is occurring with a 3.2 GHz P4 with 1.5 GHz of memory ;) 73, Roger W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: Linrad-02.05
Hi, Leif, Just a quick final note before I run off to work: THe previous note of course referred to xLinrad, as does this one. I went back to xLinrad and found that: 1st FFT storage time was 1 second. I left it there 2nd FFT storage time was 5 seconds. I left it there Baseband storage time was 200 seconds. I changed it to 9 seconds. I turned off AFC/Spur rejection. Other parameters were all left at the defaults set by xLinrad when it installed. After the above, moving the mouse across the screen when in receive mode again caused xLinrad to crash. I hope the above helps. I don't know if my system is using MMX routines. Does anyone know an easy way to check this? Linrad 02.05 under svgalib continues to work ok here. 73, Roger W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: Linrad-02.05
Hi, Leif, THis is just some 'user feedback' from 1.37 and 2.05 ;) Windows: Linrad-02.05 is working fine so far. I haven't made it fail under windows. Linux: LInrad 01.37 seems to work fine here at home. I haven't put it thru its paces at Hilltop yet. LInrad-02.05 works fine under svgalib. I haven't identified any problems yet. below is all Linux with Xwindows version of Linrad using Delta44 as input Linrad-02.05 is still flaky under Xwindows. I tried it with mlock all on and mlockall off and it was flaky with both. With mlockall off it can take 5 tries of ./xlinrad to get it started. With mlockall in either setting, it has crashed when: The mouse is moved across the screen [no click necessary] A parameter window was changed in size by pulling it with the mouse. A parameter [e.g. number of averages in waterfall, waterfall baseliine, waterfall gain, high resolution waterfall number of averages, etc] is changed. The size of the whole linrad window is changed by pulling it with a mouse. Also, it sometimes crashes after a time few seconds to 2.5 minutes with no mouse use, but sometimes has run more than 10 minutes with no problem I can't pull the S meter away from the bottom left corner -thats all I found so far. I compiled with my users_hwaredriver.c file, which could make a difference I guess.

Some of them are probably due to insufficient ram memory (Too large storage times selected.) Under svgalib the user has the option to select whether mlockall should be used to detect swapping to disk. This works fine on older computer where it is really important. I assume older computers are run with older Linux distributions;-) Modern distributions do not always behave well. Fedora crashes completely. The call to mlockall never returns so there is no error code to act upon I had intended to never use mlockall under X11 since the graphical interface is not very useful on small computers anyway. Unfortunately I made it the other way around so the memory locking was always enabled. In 02-05 the user has a choice - and some other parameters
[linrad] users_hwaredriver.c added features
Hi, All, I put a zip file and a tar file containing my Linrad users_hwaredriver.c file and some support files on my website at http://www.nitehawk.com/w3sz/Lin-2-1000MP.htm The page supplies some explanation. To download, just go to the bottom of the page and click on 'zip.file' or 'tar file'. Each archive file contains a copy of users_hwaredriver.c that includes: 1. Leif's routines to control the WSE hardware 2. my routine to take frequency data from Linrad and send it out the serial port to FT1000MP. 3. Leif's routines for putting a user_window on the screen to allow entry of user_parameters while Linrad is running 4. my modifications / additions to #3 These modifications are so that one can enter a frequency shift parameter [par2 in the program, labeled SH(Hz) in the user_window] using the user_window on the Linrad screen to fine tune the frequency sent to the FT1000 by #2, so that the FT1000 is brought to exactly the same frequency as the Linrad hardware [whatever that happens to be] so that should the Linrad hardware and the FT1000 and its transverter drift apart over time the resulting delta-f can be brought back to zero without having to recompile Linrad [which is what I had to do before adding this routine]. The value of par2 is easily optimized using Spectran or the WSJT waterfall [for example], and just feeding in to whichever of those programs is used the audio signals from both the Linrad hardware and the FT1000, and adjusting par2 on the Linrad screen until the signals are superimposed on each other on the Spectran or WSJT waterfall. I use this on two meters, so the IF frequency for the transverter I use with the FT1000 to transmit on 144 mHz is 116 MHz. This is of course subtracted from the Linrad receive frequency before sending the frequency information to the FT1000. So that this scheme can be used with other transverter intermediate frequencies, the transverter IF frequency is also adjustable via the user_window. This variable is par1 in the users_hwaredriver.c program, and is labeled SH(Hz) in the user_window. These two parameters could of course have been combined into one, but I find it easier to set the IF frequency [in this case 116.0] once and then leave it alone, and to just enter subsequent small adjustments due to drift directly in Hz, rather than having to type in 1160.621 rather than just 621 when the frequency has drifted slightly and needs to be adjusted by 621 Hz, for example. The archive file also contains some files of the form aa that put the user_window at a reasonable position on the Linrad screen and set the initial values for par1 and par2 [and save the new values of the user_window positions and the par1 and par2 parameters for subsequent sessions if they are changed]. If you don't have the file 'junkfile', which is an empty file, in the Linrad directory then Linrad will crash when a mode is entered by typing 'a' or 'd' or whatever, as it looks for this file immediately upon entering a mode. This file is included with the support files in each archive.

[linrad] users_hardware.c correction
Hi, All,
It is late but I thought I would post this so I don't forget to do so.
For 'quite a while' I have put my addon routines directly in hwaredriver.c
or more recently in users_extras.c because everytime I put anything in
users.c renamed to users_hwaredriver.c I got error messages and a failure
to compile.
I REALLY needed to implement Leif's nice window/parameter protype routines
for an extra parameter window in Linrad, and these are in users.c, so this
evening I got off my lazy butt and looked for the answer to the problem
instead of just working around it.
The problem is solved with just a little change of the code. It is due to
a single misplaced }, which needs to be removed from one line and added
a few lines higher in the code. I hope that I have placed the bracket
correctly. It compiles fine and so far the code seems to work reasonably
well with the bracket placed as I have shown it. The missing bracket was
added at [or about] line 335.
Immediately below is a fragment of the corrected code, and below that the
original code which needed correction:
corrected code:
if(mouse_x ug.xleft+2*text_width mouse_xug.xright-2*text_width)
{
if(mouse_y (ug.ytop+ug.ybottom)/2)
{
numinput_ypix=ug.ytop+2*text_height;
numinput_chars=12;
erase_numinput_txt();
numinput_flag=FIXED_FLOAT_PARM;
par_from_keyboard_routine=new_user_par2;
}
else
{
numinput_ypix=ug.ytop+text_height;
numinput_chars=4;
erase_numinput_txt();
numinput_flag=FIXED_INT_PARM;
par_from_keyboard_routine=new_user_par1;
}
} //added } added } HERE
else
{
// If we did not select a numeric input by setting numinput_flag
// we have to set mouse_active flag.
// Set the routine to mouse_nothing, we just want to
// set flags when the mouse button is released.
current_mouse_activity=mouse_nothing;
mouse_active_flag=1;
}
// } removed } HERE
}

[linrad] Linrad and Debian Etch and Alsa
Hi, All, I have Linrad-02.03 working on Debian Etch without OSS. I decided to wipe the hard drive and to start a Debian Etch installation again from scratch without installing OSS at all. SO Alsa is being used for sound. I do not yet understand the best way to set the various [and numerous] Mixer controls, but I DO have things working and I am listening to 2 meters using the WSE Linrad hardware, which Linrad-02.03 is controlling properly. I do know that I select the various cards for adjusting mixer settings by typing alsamixergui -c0 or alsamixergui -c1 or alsamixer -c2 [I have 3 cards in the system]. The system parameters are: Debian Etch netinst downloaded 3-28-6. IT is NOT the 'daily' version. Stock kernel that came with it 2.6.15-1-486. I have not yet upgraded to -686-smp. At this point I don't know if I want to ;) gcc version 4.0.3 nasm version 0.98.38 svgalib-1.9.24 run in NOHELPER mode with VESA driver don't forget mdev /dev/input/mice Delta44 input to Linrad Intel ICH5 output from Linrad Intel ExtremeGraphics i810 onboard video Pentium 4 3.2 GHz. I think I have 1 GB of memory. ALSA /sound components that I have installed on top of the standard install include: alsa-base alsa-utils alsamixergui alsa-odd alsaplayer-alsa alsaplayer-common alsaplayer-gtk alsaplayer-jack alsa-source alsa-tools alsa-tools-gui alsa-utils gstreamer0.8-alsa libasound2 libmikmod2 libpt-plugins-alsa libsdl1.2debian-alsa linux-sound-base All of these are standard debian packages that can be gotten with apt-get or Synaptic. It seems that I have to keep the Linux Sound Server Startup turned off for Linrad to see the ICH5 for output. CPU utilization per Linrad is 16.8%. I have rebooted the computer to make sure things still work after reboot. They do. So 4 input channel 96000 Hz sampling will work with this setup without the need to invoke OSS and its funny ways. Hurrah, Hurrah!! ;) I will play with this more extensively to see if it is stable and if anything may be broken. I can already say that on loud signals I can hear a regular 'ticking' sound, but I don't notice this with weaker signals. IT is annoying but doesn't compromise intelligibility. 73, Roger Rehr W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

This is just an FYI. Since I am sending this via the list I will post a couple of other interesting things. I am playing with installing Debian testing [Etch] using Netinst, from http://www.debian.org/devel/debian-installer/ This installed OK except that I had to go in and set the network parameters. For some reason netinst assumed DHCP, so I had to enter the dnsservers and ip address/netmask/gateway stuff after install. svgalib install ended with an error, with svgalib_helper failing to install [of course]. Setting the NOHELPER option rendered this problem moot. I again had to use the mdev /dev/input/mice statement to get the mouse to work in svgalib. I had to use the VESA driver with my Intel i810 video to get decent video resolution choices in svgalib. OSS remains a problem. It will install and I can turn it on with ./soundon and configure it with ./soundconf, but when it is used either via ./osstest or ./linrad, it will lock up the computer thoroughly so that I must hold in the ac power button for about 10 seconds to shut off the computer and then reboot. cntl-alt-del, cntl-alt-F7, cntl-alt-F8, escape, cntl-C, etc have no effect in this situation. To get OSS to install I had to use my usual trick of renaming soundcore.ko to soundcore.ko.old to stop the sound from installing so that OSS could install. I would recommend staying with the stable form of Debian at present [Sarge]. The most recent kernel I have gotten to work with Sarge is 2.6.12.x.

[linrad] 96000 Hz sampling from stock laptop
Hello, All, I was playing with a laptop tonight and found to my surprise that it played back 96000 Hz sampling rate I/Q wave files through both Winrad and Linrad with no problem, giving me [nearly] 96000 Hz bandwidth on my laptop, with no special effort on my part. It also [of course] plays back 96000 Hz sampling rate adfiles on Linrad, and in fact is playing back the dual-receive-polarity 96000 Hz adfile of EME named frh1135 [obtained from Leif's website] as I type this. Since it doing both H and V receive polarities and doing I/Q, it must be using 4 channels for input alone; very nice for a stock laptop ;) All of this is using Windows; I made no attempt to put Linux on this machine [and won't do so in the future, either]. The laptop is a simple Dell Inspirion 600m. I think I've had it about a year or so [maybe longer]. It is pretty basic and not a speed demon; its main use is just to provide a VPN link back to the office when I am on trips. It has a Pentium M running at 1.6 GHz as I recall, and only 512 MB of memory. It is running XP Pro SP2. Everything is stock; I did nothing to upgrade hardware or software. The stock audio is SigmaTel C-Major Audio. It is handling the frh1135 96K dual-polarity file on Linrad fine with no pauses, hitches, or speed warnings. Of course, it would be possible to change the parameters so as to overwhelm the processor, but I am running with a 'reasonable' set of parameters without tweaking with no problems. I see from the SigmaTel website http://www.sigmatel.com/support/product/#9200 that many chips from their [notebook PC] STAC9200-9700 series Codecs will sample at 192KHz and have 24 bit resolution, so maybe my laptop can sample even higher than 96000 Hz. Also, my Inspirion 600m is not complaining at my sampling at 96000 Hz for the input to Linrad and only 8000 Hz for the output. For demo purposes and playing around, all this means that at least some fairly recent if not state-of-the art laptops will provide reasonable usability with Linrad and Winrad right out of the box. I've found that I really need a display width of around 90 KHz or more for doing EME and microwave stuff, so its nice to find a laptop that will allow me to do a demo with the standard configuration that I use when I operate. This may be useful info to some of you who want to get started with Linrad or Winrad and have a laptop sitting around, or who want to do a demo somewhere at 96000 Hz sampling, but don't want to lug the big tower PC to the demo site. I suspect that this is all 'old hat' to the computer gurus out there, but it was news to this simple user. I'd be interested in hearing from others who find that their stock laptops [or desktops] sample at 96000 Hz or greater and work reasonably well with Linrad and Winrad. This would probably be a useful list to compile and perhaps place on something like Rein's site http://www.nitehawk.com/linrad_dat/ 73, Roger Rehr W3SZ -- Roger Rehr W3SZ http://www.nitehawk.com/w3sz/ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: Linrad for Windows
Hi, Sergio, Thanks for the note! I think you are exactly right. I thought about but did not get rid of the path to the diversity antenna. Clearly I should have ;) Let me know if I can help in any way! 73, Roger W3SZ -- Original message -- From: Sergio [EMAIL PROTECTED] Hello Roger, nice piece of information from your side (as usual). We're looking to remote some stuff here so it is very valuable to get these heads up. I will try to check TeamSpeak out and see if I can come up with something, if is not too much of a hussle for you I hope you don't mind if I'd drop you a couple of lines with some question. Regarding Dlinks I've personally used some 900AP+ (the 22MB ones - old) for a long time with no problem at all, but on a short path. Two identical units, one as an AP and one as an AC. Lately Dario (IW2FZR you might have seen him on moon-net) expressed his desire to remote his station which is about 20 miles from his home. As I don't use them anymore, I modified these old units removing the diversity switch and routing the rf out to a standard SMA connector. Well those things have changed face, one shall know how bad are those diversity switches. The isolation between the ports is as bad as 4-5dB! That means that even if one is switched on the outer antenna is anyhow dissipating almost 50% of the power on the other antenna... and on the rx side... One unit has doubled the power out and begun definitely 'long heared'. The second unit went from measured 9mW out to 70mW out! That switch was horful! I did a third one of a friend of mine, same stuff almost 8 times the power out and a super rx now... I also noticed that on long paths it is necessary to shorten the AP beacon very much to avoid to have 'black holes' in the coverage. Well with the two units and two 1m dish Dario and I did the 20 miles with incredile signals... That is not bad. Sorry for long tale, thanks for your info, Regards Sergio IK2MMB w3sz wrote: Hello, All, Those of you with a long memory will recall that several years ago [late 2002 or early 2003] I wanted to use Linrad [Linux version, of course] remotely but was stymied by its use of svgalib for graphics. Svgalib is a local graphics solution, and so that meant that while one could run Linrad remotely, one couldn't see the screen at the remote location. A network workaround was found and made a part of Linrad by Leif, but it was less than ideal to use in practice. This was definitely NOT Leif's fault, but just a consequence of the environment surrounding Linrad in Linux. The problem was basically that if anything failed at the remote end or in the link, since you couldn't see the remote Linrad screen on your monitor, you had to know the exact sequence of keystrokes that you needed to input to blindly re-establish the Linrad network link and get Linrad running in whatever mode you chose after restarting Linrad remotely with RealVNC. And not all of the functions were available remotely. So it was usable, but not an ideal solution when the remote site was several miles away. There is nothing like driving 4 miles [times two] to do something that just takes a few seconds to do when one can see the screen ;) A moment's thought would indicate that the Windows version of Linrad, which does not use svgalib, should work remotely with no problem as long as the link has enough bandwidth, and this is in fact the case. I played yesterday with running Linrad for Windows remotely over a 4 mile Wi-Fi link and it worked fine. RealVNC did a good job of running Linrad for Windows remotely, and I used TeamSpeak to send the audio across the link. I let things run for several hours and there were no hangups or problems. Even resizing Linrad screen objects remotely was no problem. There was no indication of any more audio latency over the wireless link with TeamSpeak than I experienced on the wired network at home, even though I also had two video channels running across the link at the same time [constant ipcamera monitoring for security]. So if you want to run Linrad remotely, Linrad for Windows makes it easy! I also tried Speak Freely for the remote audio channel over the network at home, and it worked OK. But I didn't use it over the 4 mile link, and so I can't comment on that. There may be better network audio solutions than the ones I tried, but TeamSpeak worked fine for me, and both TeamSpeak and Speak Freely were simple to install and get running. The link is an 802.11b link using a Senao wireless bridge at each end. It has been running for about 14 months; before that I used some D-Link hardware that was TERRIBLE and gave lousy link performance. 73, Roger W3SZ

Hi, All, I have attached my par_userint file and also listed it as text. Whether the reflector will let it thru as an attachment or not I don't know [I suspect not; thus the text version].

You have to go to the main Linrad page which is referenced on the Linrad Home
page or Starter Page.
The files are at the bottom of the referenced page. I downloaded them from
there Sunday evening and had a good time playing with Linrad for Windows and
listening to the 2 meter beacons I can hear at this QTH, using Linrad for
Windows.
I would paste the URL here but you should be able to find it and I am at work
and sneaking this email in among other things I really must be doing ;)

Hi Leif
This is a good new for me, as I'm still guessing the simplest Linux distro
to use on my hd, so I'll be glad to test it, but on the Linrad web pages
I was not able to find any new about Linrad 02.00, as soon as it will be
available please inform me I'll be glad to be a tester as Linux is good but
I've not to much time in order to be quite expert with sw setup and so
on.:-(
Hope to read some new soon..

Oggetto: [linrad] Linrad-02.00
Hi All,
Multithreaded Linrad is now available for normal receiving
functions under Linux and Microsoft Windows.
Support and side functions are generally untested and may
produce different kinds of errors.
There is a modest penalty in going from a single thread
with tight timing control to a multi-threaded structure.
To run a specific combination of soundcards with
identical processing parameters Linrad-02.00 will need
a somewhat faster CPU and some more memory compared to
the Linrad-01.xx series.
There is a big penalty for using Microsoft Windows. A much
faster CPU is required..(But today that is not any
problem at all.)
--- Unsolved problems ---
1) Linrad can not read or write to the parallel port.
I know it can be solved. Others have done it so I hope
someone else can make the necessary additions:-)
2) Delta44, Lynx Two and presumably all other 32 bit
capable soundcards only give 16 bits. The reason is
most probably that I open in WAVE_FORMAT_PCM with the
WinAPI waveInOpen function. Here is what Microsoft
writes:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcesdkr/htm
l/wcesdkrwaveInOpen.asp
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcesdkr/htm
l/wcesdkrwaveformatex_str.asp
Bits per sample for the wFormatTag format type.
If wFormatTag is WAVE_FORMAT_PCM, then wBitsPerSample
should be equal to 8 or 16. For non-PCM formats,
this member must be set according to the manufacturers
specification of the format tag. Note that some
compression schemes cannot define a value for
wBitsPerSample, so this member can be zero.
So, is there anyone on this list who knows what the
manufacturer specification is for wFormatTag in the
WAVEFORMATEX structure when opening the sound input
on a Delta44 or a Lynx Two soundcard???
3) Linrad is unaware of how much CPU time it uses.
Extracting such info seems exceedingly complicated and
maybe it is not really useful since the device drivers
seem to fail due to latency problems on computers
with marginal CPU resources.

[linrad] Re: knoppix 4.02 and linrad
Hi, Alessandro, Did you try re-downloading the live CD to make sure it wasn't corrupted during the download? If you downloaded the OSS version of the Live CD [I made both OSS and ALSA versions], there is a problem in that the free version of OSS that I put on the CD has expired. I made a new version of that Live CD a couple of weeks ago with a new copy of OSS on it that should be good for another few [??6??] months, but I don't recall if I ever got around to uploading that to Leif's website, where it resides. I can't check from work, and I am at work as I type this, so I can't check to see what version of the file I have on the website right now. I will check later and put the new version of the file there if it is not there already some time in the next few days. I will post to the list when I am sure the new version is there, and also sure that it works after being downloaded. It is possible that I already did all this already and just don't remember. If you would tell us exactly where the Linve CD install stops, and what the last text on the screen is that you see, we'd be more likely to be able to figure out the problem and offer some help. If you see something like Kernel panic as the error message [as your statement that the 'Kernel won't load' might imply], I would think that you may have a corrupted copy of the Live CD. Other messages might imply that the Live CD doesn't recognise some of your hardware. Without more information, its not possible to guess what the problem is. Perhaps some real Linux gurus [which I am defintely NOT] lurking about will have more thoughts on this. But please send us more info so we hopefully be of more help. Send it to the list, not to me personally, so you get some better input than that which I can offer. In terms of trying to add Linrad to another version of Linux, if you go to Leif's Linrad website [which usually comes up as the first listing when I Google 'Linrad'], Leif's instructions will walk you through installing everything you need to run Linrad onto another version of Linux. http://www.nitehawk.com/sm5bsz/linuxdsp/linrad.htm is the URL. 73, Roger Rehr W3SZ -- Original message -- From: Alessandro Santucci [EMAIL PROTECTED] Hallo everybody, I'm a new on this list and interested in test linrad with my Ham PC (PIII 256 MB); unfortunatly the live CD by W3SZ doesn't load the kernel, I don't know why.
