Show Notes #076

Introduction:

Announcements:

  • The Black Sparrow Media application for iPad, iPhone and iPod has been submitted to the iTunes store. It is just awaiting validation from Apple, which may take up to two weeks. We'll let everyone know when it's available.
  • Special Event Station W0S (Whiskey Zero Sierra) will be operating from the Titanic Branson Museum from April 13-15, 2012, commemorating the 100th anniversary of the Titanic disaster. Russ, K5TUX, will be operating the station at some point.

Feedback:

  • Scott, AD7MI, asks for help linking APRS and his his Davis Vantage Pro2 weather station with Xastir. Our hosts suggest trying one or both of these:
      • Meteo - Davis weather station platform software for Linux. You can subscribe to the Meteo mailing list by sending a subscription request to meteo-request@lists.othello.ch. It has been several years since Meteo was updated, and is still not at version 1.0. You must download the .tar file from the web site as it does not appear in the distribution repositories.
      • wview- Cross-platform weather station software. It does need an internet connection if you are going to contribute information to various weather sites, such as:

        This program is under active development. Even if it requires a work-around to perform as you wish, it may be worth the trouble. If you've ever configured a Linksys router, the web interface of wview looks a lot like that. wview has a support site via Google Groups at https://groups.google.com/group/wview.

    Let us know how you get on, Scott!

  • Paul, M0PGX, replied to our recent discussion of D-STAR and suggests trying the AllStar Link Network. Like EchoLink, it allows you to talk to other ham radio operators using just your computer and a microphone, including those operators running D-STAR.

    Russ signed up for the AllStarLink network; it's very similar to joining EchoLink. AllStar uses the Asterisk VOIP system, and Jim, WB6NIL, is the author of the repeater link software. Russ had success using a Mac computer, but not with a Linux machine.

    Richard sees the biggest problem with EchoLink is that it only allows one connection per IP address, so you can't have both a server and client at home. The EchoLink site only sees your IP address assigned by your ISP, which limits you to one connect from home. In this respect, AllStarLink appears to better in that it seems to allow multiple connections.

    AllStarLink is available in several combinations of Linux and Asterisk:

    • ACID - based on CentOS
    • Limey Linux - based on embedded Linux and bootable from a flash drive, and runs ONLY on several specific Mini-ITX motherboards.
    • Pickle - a specialized embedded Linux distro designed to operate on a BeagleBoard-xM (and DMK Engineering LOX board).

    Russ then provides an overview of setting up an AllStar Link client.

  • Back to Paul's email, he suggests we use the term "digital mode" when we should say "protocol", which brings us to...
  • Leif, KC8RWR, responded to Paul's comment that D-STAR specifies a protocol, modulation mode, voice codec, etc. The modulation mode used is GMSK.

    Richard defends the use of "mode" as appropriate as the definition allows it to mean "a method or means of doing something". For example, CW vs DFCW (dual-frequency CW), where DFCW uses frequency shifts to distinguish dots and dashes, rather than two different lengths of the same frequency, and spaces. Both are CW.

  • Leif, KC8RWR, also comments on the possibility that he's been nitpicking, as well as the use of Q-signals in voice conversations.
  • Bill, KE5WMA, suggests that hobos migrate to New Orleans from Dallas this time of year because Dallas doesn't have Mardi Gras!
  • We received a donation from Bill H. Thanks, Big Poppa! 🙂

LHS Episode #076: BIG PAPA

After our quick renumbering, we come now to Episode #076. It didn't start out as an all-feedback episode, but that's how it wound up. The best part is, we had such good feedback from our listeners it made an entire show. As it also happens, most of our discussion revolves around digital mode communication for amateur radio using Linux. We touch on D-Star, Echolink, IRLP, Allstar Link and more. If you're interested in using computers to connect to your radios and talk around the world using a multitude of digital technologies, including VoIP, this is the episode for you.

Please keep those donations coming in for our Hamvention Fund, if you're able. We want to be a part of Hamvention and we hope you will be, too. Thank you for all you do.

Episode Renumbering

In case anyone has seen weird behavior in the RSS feeds or on the Web sites, let me explain:  I have renumbered episodes after #018.  Back then I recorded a couple of updates from OSCON 2010 and called them Episode #018A and Episode #019A.  Not long after that, the discrepancy in numbering started to eat at me.  Now a couple of years later, I have decided to do something about it.  All of the episodes have been renumbered, meaning that we're a couple of episodes ahead of where we were.  This will probably cause a little bit of confusion in the short term but overall I am happy that it is done.  Nothing else has changed, just the numbering scheme. Thank you for your patience while we go through this brief transition period.

LHS Show Notes #075

Introduction:

  • We're a little light on content, but we'll make up for it with enthusiasm!

Announcements:

Topics:

  • Linux Mint 12 Review
    • Richard has been using Ubuntu for some time, but he's been unhappy with the latest version. He's rediscovered Linux Mint! Version 12 is out, with Gnome 3, Gnome 2, MATE, and Cinnamon, and he gives a brief review.
    • His primary needs: browser, email, Audacity, XChat, and a few others.
    • Using the Gnome 3 desktop, as a desktop fills with icons, a new desktop is automatically created.
    • By moving the mouse to a hot corner, you'll see a high-level view of all your open applications.
    • Russ has been using Linux Mint Debian Edition, so he's missing out on the Gnome 3 goodies, at least for now.
    • Our hosts then drift into a discussion of various desktop managers and visual effects.
  • WINE: Wine Is Not an Emulator
    • WINE is a collection of libraries for Linux that support Windows library calls from a Windows application.
    • EchoLink, for example, is a Windows application works quite well under WINE on Linux.
    • If you can't find a native Linux application that does what you want, you may find that WINE will allow you to run the Windows program.
    • There are a couple of different versions of WINE, all based on the core version of WINE.
    • Cedega: a version of WINE that supports a variety of Windows games.
    • CrossOver: a version of WINE that originally focused on supporting business applications such as Internet Explorer and MS Office, but has also expanded to include some games and running Windows applications on a Mac.
    • Richard browses the list of ham radio applications in the WINE application database.
    • Russ talks about installation and configuration:
      • Red Hat/Fedora: yum install wine
      • Debian-based: apt-get install wine
      • Some repositories may not have the most recent version of WINE (1.4 at the time of recording).
      • Under System Tools (in Linux Mint, or Debian) there is a WINE Configuration tool.
      • To install a Windows program under WINE, download the Windows installer application. At the command line, type "wine [name of installer executable]", and the setup program should proceed just as with Windows. A program icon should appear under the WINE program folder, and the program will, hopefully, run just like in Windows.
      • Some Windows programs will run just fine under WINE; others won't. Give your favorite a try and see!
    • One of the most-wanted ham radio applications, Ham Radio Deluxe v. 5.0, does not run at all under WINE. If you can find a copy of HRD v. 4, it should work under WINE. Remember, too, the native Linux application fldigi does much of what HRD would do.
    • Russ has also tried the N1MM Logger under WINE, and it worked fine.
    • The Winetricks tool might help get a Windows application running under WINE.
    • The WineHQ forum is a good resource for help.

Feedback:

  • We had a donation from William A. Thank you!
  • Leif, KC8RWR, continues a comment dialog about the origin of CUPS in Episode 67.
  • G8FXM, mentioned LHS in his blog. Thanks, David.
  • The Hoosier Hills Ham Club linked to the LHS site and we linked back. Thanks to W.W., KB9TMP.
