LHS Show Notes #065

Posted on by Russ Woodman

Introduction:

  • Welcome to another episode of Linux in the Ham Shack.
  • Richard has moved to another QTH, and that's provided some challenges.

Announcements:

  • The LHS Ambassador Program needs your help. Russ explains what the LHS Ambassador program is all about and how you can get involved. If you're interested, please contact us at ambassadors@lhspodcast.info
  • Richard gives an update on the archiving of Resonant Frequency, The Amateur Radio Podcast.
  • Richard complains about the Internet service at his new location, and Russ offers a tip about using wget -c for downloading large files.

Topics:

  • Richard updates us on his AX25 project and moving to a new location.
  • The Linux kernel goes 3.0: So what? Russ talks about the new Linux kernel, v. 3.0, recently released, and what you can expect.
  • Your first license: What should you expect? Richard describes the process for getting your first amateur radio license. At one time, proficiency with Morse code was a requirement, but no longer. Richard used the Gordon West training materials to prepare. Having a local radio club or another ham can be a great help. There are two volunteer examiner groups: ARRL and W5YI. Both offer training materials for their examinations. When you go to a testing session, be sure to bring the required materials. After you pass the test, check the FCC website for your callsign. It often shows up just a few days after taking the test. Most importantly, after you get your callsign, get on the air!
  • Revisiting OpenHatch (see episode 059). Russ discusses the OpenHatch project and how you can contribute to the open source community. There is a simple sign-up process to join OpenHatch. You can use OpenID or several other authentication services. OpenID can be used with several web applications. Once you join, you can specify the various skills you have, and the type of assistance you'd like to provide, such as development, bug fixing, documentation, etc. You can also start a new project or link your own project to OpenHatch. You'll find development, testing and documentation opportunities.
  • Russ gives an update on getting SvxLink to work. He had the build of version 11.05 blow up with an error about missing include files. He Googled the error message and found the answer. So he now has a working EchoLink server using SvxLink on 146.225 MHz. So, while it may be a bit challenging to build, it can work and provides a native Linux EchoLink program. (Thanks to Rick, K9AO, who sent an email that gave Russ the push to finish his SvxLink project.)

LHS Show Notes #064

Posted on by Russ Woodman

Introduction:

  • Apologies for being late with this episode.

Announcements:

  • LHS had planned on attending the Ohio LinuxFest on September 9-11 in Columbus,OH, and the Huntsville, AL hamfest Aug 21-22, but it's just too expensive. To address that, LHS has started the LHS Ambassadors program where listeners of the show act as representatives for LHS at events. If you're interested, please contact us at ambassadors@lhspodcast.info
  • When you make a donation to LHS, you can choose to appear on the Sponsors page on the LHS website.
  • Linux Format magazine, the producers of the Tux Radar podcast, recently reviewed various Linux-related podcasts, and LHS wasn't even mentioned! Ouch!
  • Richard announces the demise of Resonant Frequency: The Amateur Radio Podcast. Richard is looking for a place to post the articles and other content. The podcast episodes are saved at the Internet Archive, and the videos will remain on YouTube.

Topics:

  • WinLink and AX.25
  • Richard describes his trials and tribulations getting a WinLink packet gateway working under Ubuntu Linux.
  • For the most part, Richard followed the instructions provided by Charles, K4GBB: How to install RMS Gate.
  • Richard and Russ describe the steps in the Howto and possible pitfalls. Richard notes that you'll probably want to run the commands as the root user, either by logging in as root or using sudo.
  • (Note, near the end of Section 4 of the Howto, it appears the author left out the "wget" in the command to retrieve the script. On the page it reads: 
    Get Script – Bernard has written a little Housekeeping script...
    https://f6bvp.free.fr/logiciels/ax25/rc.init.script && ...
  • I think that command should be: 
    wget https://f6bvp.free.fr/logiciels/ax25/rc.init.script && ...

    Note that I've shortened the lines with ellipses here. -Ed.)

  • Other useful links:

Promo:

  • Ohio LinuxFest will be held September 9-11, 2011 at the Greater Columbus Convention Center in Columbus, OH.
  • Linux in the Ham Shack promo from the Low SWR guys. Thanks!

Announcements:

  • Our best wishes for a speedy recovery to MadamMoo!
  • Our regular hosts are joined by Torsten, XE2/K5TOR.

Topics:

  • Firefox 4 has been out a while, and version 5 beta is available at the time of recording. Our hosts discuss. The first thing Russ noted, was the increase in speed! Look for versions 6 and 7 before the end of the year. (As I write this, version 6 has been released. -Ed.)
  • Kudos to The Linux Link Tech Show (TLLTS) and their interest in amateur radio. One of the hosts, Joel, aka "gorkon", W3RAZ, has recorded a couple podcasts for Hacker Public Radio: Episode #738 is an introduction to amateur radio, and Episode #756 explains the basics of radio. Another TLLTS host, Allan, is N3MAW.
  • Leo LaPorte of This Week in Tech has started a podcast about amateur radio. (It's Ham Nation with Bob Heil, K9EID, and Gordon West, WB6NOA, under the TWiT banner and with Leo's support and occasional participation. By the time you read this, Leo has his license and is now W6TWT. -Ed.)
  • Russ describes the Linux from Scratch project that provides instructions for building your own custom Linux system, entirely from source code. Russ plans on providing more details of his experience with Linux from Scratch on a future episode of the QSK Netcast.
  • Our hosts tried Ubuntu 11.04, Natty Narwhal, and discuss it, good and bad.
  • Russ also tried Fedora 15, and liked the default desktop environment.
  • Richard likes PCLinuxOS, and SUSE Linux.
  • Linux Mint gets a mention, too.
  • In future LHS episodes, look for information about svxlink, an EchoLink client for Linux, and codec2, an Open Source and patent-free audio codec.
  • Torsten has had problems installing CQRLog on a 64-bit machine. Russ recommends installing the ia32-libs package to provide the needed 32-bit libraries. In Debian-based distributions, you can install that package with the command "apt-get install ia32-libs". More information about running 32-bit programs on a 64-bit machine with Debian-based Linux is here.

LHS Show Notes #062

Posted on by Russ Woodman

Introduction:

  • Introductions, chit chat, a bit about the Dayton Hamvention, Texas Linuxfest, and the Belton hamfest.
  • LHS will be at several events this summer:
    • SouthEast LinuxFest (SELF), June 10-12 in Spartanburg, SC. (Yes, I know, by the time you hear this episode, it's come and gone.)
    • Huntsville Hamfest August 20-21 in Huntsville, AL.
    • Ohio Linuxfest September 9-11 in Columbus, OH.
    • Stop by and say hello to Russ and Cheryl!
  • Richard may be attending the Texoma Hamarama October 21-22 in Ardmore, OK.
  • Russ tells us about the sewer failure at Dayton. Only two restrooms in Hara were working Saturday afternoon. Apparently it was fixed by Saturday evening.

Topic: PulseAudio

  • Richard's son is trying to start his own computer repair business and recently he received a call from Misha who wanted him to fix a sound issue on her Sony Vaio, which dual-boots Windows 7 and Ubuntu 11.04. Sound worked fine in Windows, but not in Ubuntu, and she preferred using Ubuntu. After working with the machine for a while, he figured out that PulseAudio was the problem, and replacing it with ALSA fixed it.
  • While researching the problem, Richard discovered PulseAudio problems exist on more than just the Sony Vaio. He also found PulseAudio problems with Ubuntu, Fedora, Open Suse 11 or higher, Arch Linux, Zen, and Sabayon, and with both Gnome and KDE desktops.
  • Two sites in particular were helpful:
  • Russ and Richard discuss Linux audio problems, and the current state of PulseAudio, particularly with WINE. Russ notes that he's had no sound problems under Linux Mint.
  • Russ describes various ways to troubleshoot PulseAudio issues on Linux.
  • In Gnome, right-click on the speaker icon and select sound preferences. From here you can examine the hardware, choose a sound profile, configure your inputs and outputs, and see which applications are using PulseAudio.
  • There are a variety of utilities useful for debugging PulseAudio problems:
    • paman (PulseAudio Manager Utility). Install it with the command "apt-get install paman". It tells you a lot of information about PulseAudio, including "sinks" and "sources". You can also use it to set volume levels with greater control than with the desktop audio manager.
    • paprefs (PulseAudio Preferences Panel) Install it with the command "apt-get install paprefs". Allows you to perform advanced functions such as connecting PulseAudio servers together, send sound from one server to another, create virtual sound devices, etc.
    • pavucontrol (PulseAudio Volume Control) Install it with the command "apt-get install pavucontrol". Allows you to see every application that accesses PulseAudio, set volume levels per channel, and other configuration settings.
    • pavumeter (PulseAudio VU Meter) Install it with the command "apt-get install pavumeter". Creates a VU Meter window that displays your audio levels.
    • padsp, pamon Install with the command "apt-get install pulseaudio-utils". pamon will allow you to capture the bytes of audio data. padsp allows you to pipe the audio from an application that does not normally support PulseAudio, into PulseAudio.
    • Remember, you can use the "man" command for help on any of these commands. For example, in a terminal type "man padsp" for help on the padsp utility.
  • Check out Ted's sound card programs for ham radio. They are all now PulseAudio compatible.
