[linrad] Re: Win-network / UKSMG_50MHz ; Re: [linrad] Re: Linrad-02.22
Dear Leif, Hopefully you had a good time in the tropics. I can only admire your persistence and energy in this project. What I have seen through the years is: that once you question the options for proceeding, it will not take too long before you will have a new operational solution. I am sorry that I can not help in this, but I am sure that there are some "socket-experts" in the audience! 73, "Zaba" OH1ZAA/2 At 00:25 27.2.2007 +0100, SM5BSZ wrote: Dear Zaba, This has been unanswered for a month or so..

Sure - but I have no idea how to proceed. I am sure it is quite easy - but there seems to be several different ways and there is the usual mixture of acronyms that I can not interpret at those places where I tried to get a hint. I need to know how to open a socket (or whatever it might be called) to read UDP packages under Windows. That would at least be a starting point. 73 Leif # This message is sent to you because you are subscribed to the mailing list .

[linrad] Win-network / UKSMG_50MHz ; Re: [linrad] Re: Linrad-02.22
Dear Leif! Linrad continues its great evolution and I have tried to keep the 50 MHz community up-to-date with the latest developments as I think that it is extremely usable in that part of the spectrum. Linrad's documentation is exemplary to other projects, but since development is so fast, the contents of the documents sometimes bypass the original chapter titles. Please check below whether any adaptation of chapter "headers" is needed (to keep the "googling" public on track). Maybe I interpreted some remarks too freely, or is the networking planned for the Win-version? Wherever you go in the Caribbean, maybe you can bring some of the "most wanted" on the air on 50 MHz or other bands, and at the same time put Linrad to a tropical real world test!! In any case I wish you a great trip and good relaxing! 73, "Zaba" (PJ2/)OH1ZAA ex-ZF2KZ From UKSMG Announcements (January 2007): LINRAD: like in human life names and titles may be misleading... Though SM5BSZ's page title reads "DSP radio for LINUX on Intel platforms", the wlr2-22 version works these days perfectly well with Windows (and with AMD's CPU's too, to put it overclearly...) --- The networking feature was gone for a while (with the transition from 1-xx single-treaded to 2-xx multi-threaded), but is now back in the lir2-xx linux branch and will be added to future wlr2-xx --- 73, "Zaba" OH1ZAA/2 --- Sunday, January 21 2007 at 17:13 (GMT) The latest Linrad 2.22 with network properties is available at the end of the page through this link: http://www.sm5bsz.com/linuxdsp/linroot.htm (Network not yet implemented in the Windows-version) I2PHD's Winrad 1.23 (Windows only) comes through http://weaksignals.com/ On the Web you can find several descriptions of Linrad or Winrad implementations with an input bandwidth of 15 kHz or less, though prefiltering weakens performance ... remember that the man-made noise cancelling works best with 48 kHz or wider input bandwidth. Cheap direct-conversion I/Q-circuits work amazingly well Happy New Year to you all! 73, "Zaba" OH1ZAA/OHoMZA Sunday, January 21 2007 at 16:54 (GMT) At 20:06 23.1.2007, SM5BSZ wrote: Hello Francesco, > about Linrad-02.22, for example, i'm not able to run with it (as i do with 2.20 and 2.21) the > recorded files (like FRH0135 for example and others)because when i push the "A" key it crash. > This is a minus problem.

You must use the same settings for the soundcard. Same number of channels, same sampling speed and mode (I/Q or real-valued data) Compare the par_userint files to see what differs between your two installations. 73 Leif / SM5BSZ # This message is sent to you because you are subscribed to the mailing list .

Hello Francesco, > Do you know how or if is possible to copy or make some other > job on UBUNTU, out from "ROOT" mode? > Now, due my low experience with it i can download only out from > "ROOT", but i can not make any administration. I do not quite understand this question. Presumably you are caught in the graphical interface X11 with some security functions that I do not know the details of. The standard procedure I use is to press Ctrl Alt F1 to get a console terminal where I can log in as root with full privileges for everything. The next thing would be to edit /etc/inittab # The default runlevel. id:3:initdefault: In Ubuntu you presumably have 5 here. In some distributions even runlevel 3 starts X11. In such cases I remove the file /rc3.d/SXXgdm (XX is a two digit number) Different distributions place the file at different places: /etc/rc3.d/SXXgdm /etc/init.d/rc3.d/SXXgdm /etc/rc.d/rc3.d/SXXgdm This way I always log in in terminal mode. When I want X11 I type startx. Shift between terminals with Alt F1 to Alt F6. You may log in as root on some of them and as a normal user on others. It may be a good idea to start X11 from a terminal that is logged in as a normal user. Some Linux systems do not behave well in case you run X11 as root (e.g. Mandriva). Personally I prefer Debian. It does not have any restrictions and I am allowed to run X11 as root on my own responsibility. In my experience the probability for unexpected behaviour is much higher under X11 as compared to terminal mode. The reason is that soundcards and other resources are shared with other programs. Things like changing the sampling speed with ossmix may lead to unexpected problems. There are only two valid reasons to use X11 as I see it. 1) Your videocard is not supported by svgalib. 2) You want to run other programs simultaneously. X11 works perfectly well nearly always - but one looses some valuable screen area. Starting stopping and changing the sound system is not always safe. Presumably some programs believe one does not do such things and behave as if changes to the sound system do not exist with a total lockup of the sound system as a consequence. 73 Leif / SM5BSZ # This message is sent to you because you are subscribed to the mailing list .

[linrad] Re: Linrad-02.22
Hello Leif, congrats for new release. I'll test it on my new PC with UBUNTU. I have a question for you, maybe you are much more expert on UBUNTU. Do you know how or if is possible to copy or make some other job on UBUNTU, out from "ROOT" mode? Now, due my low experience with it i can download only out from "ROOT", but i can not make any administration. Many thanks and hope to meet you again.
