[linrad] Re: problems getting inpout32.dll working with qt3 forwindows
Roger: I am somewhat confused since I believe we have incomplete information. You mention Qt3. I have several questions. Are you using the commercial licensed copy of Qt3 or are you attempting to build using Qt3 under MinGW? If it is the latter, I really do suggest you use Qt4 but forget that for the moment. Tell us why you are not using Qt4? Are you able to run MSYS and mingw under Windows XP 64? WCHAR is a 16 bit unicode character and char is an 8 bit quantity. You are in a bit of a bother I would say.

[linrad] Congratulations Roger!!
Congratulations to Roger Rehr, W3SZ! He came in first place single op low power in the ARRL January VHF Sweepstakes. Drat, this was the first one I have missed in several years and now I have missed the June VHF contest as well. I know Roger is looking forward to having all sorts of SDR stuff at his remote site and our incipient remoting capabilities with the SDR's. For those who do not know, Roger has been steadily, relentlessly pursuing the upgrade path to a first rate VHF+ station. He puts out a really great signal on 6m through 24 GHz!

Ubuntu and Linrad run seamlessly here. I did not have to compile a single module. I had to download some binaries. The trick with Ubuntu is to use synaptic package manager and run setup and add the not GPL repositories, multiverse, universe (sub atomic particles?) repositories. Synaptic is a breeze to drive.

[linrad] Re: Fwd: [softrock40] v7.0 kit run or not?
The Softrock 7 should be considered strictly a mixer and coupled with the software, an IF receiver. The SR7 has an MDS of -109 dBm (typical, I measured one at -107 dBm and another at -110 dBm). So the system NF will be high without gain in front of it. The VHF preamp in your system should determine the system noise temperature/NF as in all such systems and all things in front of SR7 will need to provide both the noise figure plus gain to overcome losses and noise floor of the SR7. If you are attempting to do EME and want a decent noise temperature (sky + antenna) to be around 60-ish degrees Kelvin and a noise floor around -180 dBm/Hz, you need a lot of gain to shove the weakest signal in 500 Hz at (say) -153 dBm above the noise floor of the SR7. There are loads of web resources and practical examples but some relevant ones would include Chomski's : http://www.nd2x.net/wa6py-MDS.html http://www.satsig.net/noise.htm http://www.mth.msu.edu/~maccluer/Lna/noisetemp.html and one really needs to use a good tool to help with all of this and I recommend a free one: http://www.hp.woodshot.com/ Bob N4HY w3sz wrote: Hi, Josh, I am not an RF expert, so take ANYTHING I say with a large grain of salt.

Leif Asbrink wrote: Hi All, Known bugs are now corrected:-) The transfer to multi-thread is not yet complete because all calls to the error handling routine lirerr(int error_code) have to be followed by a test for an error condition followed by a conditional return to the calling routine. 370 such calls need to be fixed and some of them that do graphics are in turn called from a few thousand places from where a conditional exit should also be made and so on It will take some time to complete this and it is not a very interesting work to do Before all of this is fixed, Linrad will continue after reporting an error as if nothing has happened until eventually some thread detects that the program runs with the error flag set. Normally this is perfectly OK, but if the error affects some pointer value a segfault could result. The only problems I know about right now are associated with ALSA on Debian Etch. (alsa-base/etch uptodate 1.0.10-3 If we use PortAudio, we can have a SINGLE sound system API for all operating systems and be able to immediately extend your Xlinrad to at least Intel based OSX boxes (since Portaudio presents a single API for sound on Windows, Linux, and OSX) and run this code on Windows, Linux, and Intel-Mac. The problem with Xlinrad on PPC boxes is your assembly routines of course will not work. For audio, Portaudio will not care if your underlying system is OSS, ALSA, or on windows ASIO, WDM-KS, MME, or DirectX. On OSX, it runs right on top of CoreAudio. Portaudio will also run on top of Jack. This would allow Xlinrad to feed follow on applications through a jack interface (no cables required) such as WSJT. This is because WSJT uses Portaudio already on Linux (that is my fault, I helped Joe add that to the Linux version). Portaudio will do the opening in the native mode and will also give you floating point (based on 24 bit) samples if you open the card that way and increase your dynamic range, improve your noise floor, etc. I will let you get a stable version 2.0 together before I suggest how to make this unstable again! I have some work to finish on DttSP v 2.0 which will come first but PortAudio has much to recommend it. I am kind of excited to see you get this X windows stable multithreaded version this far along. It has a lot to offer us. With some luck, Linrad-02.xx is now stable enough to get the label unstable removed.

[linrad] Re: xlinrad 02.05. Problem solved(?)
The first one cannot know whether or not a separate thread using a
pointer or the variable has initialized the contents. In the second,
typically the construct inside the
if (A ==0) {
}
braces, requires that A be initialized to zero and that some action
required by the inside of braces area has been accomplished. Otherwise,
there would be no need for the if test. This is typically why the
second fails and the first does not. If A is an unsigned integer
quantity, it does not matter that B is unitialized. The operation is
legal even if the contents are not. These kinds of assignments
typically succeed except in the case of floating point where a floating
point exception is thrown (if you are lucky!).
gdb and valgrind are tools that aid (as you can see) but they cannot
tease apart all of the logical ways things can happen. If I may, they
are not mind readers, they are the assistant in the audience aiding the
mentalist by picking the unsuspecting customer's pocket for
information! With that attitude, you will find a way to properly use
valgrind or gdb to eventually come to arrive at the error by logical
inference and deduction. I wish I could give a more satisfying answer
but you can see why it is not possible for valgrind or gdb to understand
all of the ways these things can happen.
The best case you can hope for is an explosion where valgrind gives you
the line of interest and you back it up logically to the nexus of the
problem.

gcc -g -O0 will turn off optimizations, insert debug symbols and you

Hmmm, so far gdb is black magic to me, but valgrind gives

Is there a way to get an error message when an uninited variable

On XP, if the dependencies are not there, the installer program informs the user that they need to find a driver, etc. and asks permission to go to Microsoft to hunt for it. The Delta 44 is one of those cards that refuses to participate in the Microsoft blackmail called DRM certification so its drivers are not available from Microsoft (they are Microsoft unsigned and bring up a dialog box when you install them under XP). If you insist on supporting a ten year old operating system that is no longer supported by Microsoft or anyone else for that matter, you can indeed expect it to be hard to find drivers.

Quoting myself: If I understand you right, later Windows versions would support the 2496 directly? means negated my current windows version (W98) does not support the 2496 directly Hmmm, people usually claim that Linux is much harder to install than Windows. This is not true at all, Windows is much harder because it is much harder to find the proper drive routines. I was unaware of this myself until very recently when I installed Win98 on several old computers with unknown soundcards. Unlike Linux which supplies drive routines for nearly everything included in the operating system, Windows requires that you have CDs from the hardware manufacturers. One computer was completely impossible, it has a Creative Live (SB0220) for which there is no driver available on the Internet site of the manufacturer. Luckily I had demounted the hard disk I got with the machine and by searching it I found some files belonging to the soundcard. It is the same with videocards. Windows does not auto-install many hardwares properly. One has to supply drive routines from CDs, Internet or elsewhere - but unlike Linux Windows does not tell you what card to find drivers for (Or I am not clever to enough to find out how to get the information) Look at the Windows hardware install program. Presumably it will tell you that the soundcard is not properly installed. 73 Leif / SM5BSZ -- Laziness is the number one inspiration for ingenuity.
