LHS Episode #135: A Mouthful of Potatoes

Mouthful_of_PotatoesIn this fortnight's episode of Linux in the Ham Shack, Pete (VE2XPL), returns to the land of the living. Your intrepid hosts discuss explosions in the sky, a "holiday" for ham radio operators, Linux vulnerabilities, caipirinhas, and ask the vital question: What is Allstar Link and does anyone use it? All that and more in this action-packed installment of LHS. Thanks for watching, and as always...

Show Notes #078

Introduction:

  • Richard says life has been good, lately, except for Linux Mint, but we'll get into that in a moment. Announcements and feedback are at the end of the show.

Topics:

  • Linux Mint Sux!!! (At least, for Richard.)
    • Richard's never-ending quest for a Linux distro that works for him. In the past few days, he's tried various Debian-based distributions:
      • Linux Mint 12, with Gnome 3, MATE, and Cinnamon, but he didn't like any of them. Too few configuration options for the desktop and gtkpod didn't work, and that was a deal-breaker.
      • Linux Mint Debian Edition (LMDE): one of the CPU cores wasn't running; fixed that, installed software and updates, but gtkpod didn't work there, either.
      • Crunchbang Linux: too minimalist and too much configuration.
      • XFCE on LMDE was close. Richard replaced the Thunar file manager with Nautilus.
      • Xubuntu which is Ubuntu with XFCE. It looked good, was configurable, but lacked a few features.
      • Kubuntu, which is Ubuntu with KDE. He tried installing it from the live CD, which took 25 minutes to complete. After the reboot, it generated all sorts of hard drive errors. While it's possible that the hard drive did fail, but Richard blames Kubuntu for causing the problem.
  • Russ discusses OpenMediaVault, an open network attached storage solution.
    • It's an alternative to FreeNAS.
    • Debian-based with a simple install process, while FreeNAS is based on FreeBSD.
    • Supports many features of FreeNAS, including CIFS/Samba, NFS, FTP, SSH, BitTorrent (via plugin), TFTP, and DAAP (via plugin).
    • Russ tried it in a virtual machine, and it installed easily. Once installed, all configuration occurs through the web browser.
    • While it's perhaps not as mature as FreeNAS, it's also a newer project, so it's likely to improve. At the moment, Russ prefers FreeNAS, especially v0.7, but OpenMediaVault may very well catch up and surpass FreeNAS.
  • Linux Contesting Software revisited. We covered a few in Episode 70, and here are a couple more.
    • Bill, W9YA, one of the maintainers of YFKtest, contacted Richard to inform him that YFKtest has had a major facelift, as well as adding a few features and fixing some bugs. It's available as v 0.0.10 from the subversion repository. Russ downloaded the compiled version. He picked a contest, filename for the log, entered his call sign, mode, and some other information, but he had trouble entering a contact.
    • Minos Contest Logging Software is a contest logging suite for VHF and UHF Amateur Radio Contests. The current version is 1.5.4, and is available as a download or via the Subversion repository. It's a Windows application, and there are directions on the Web site for running the application using WINE. If only they'd simply re-release with Linux-native code. Russ tried it and it does run quite well under WINE. It's an open source project under the BSD license.
  • Allstar Link Node Update: Russ now has an Allstar Link node number assigned, 28357. Allstar Link offers several packages: Limey Linux, ACID CentOS or Pickle Linux (for the BeagleBoard). Russ has been trying to get the ACiD version running on his LMDE machine so he can use it with his existing Asterisk installation. Meanwhile, Russ has his Echolink station working, node 54711.

Feedback:

  • We received a voice comment from Ed, KB4VWA, who's having trouble with some MFJ TNCs he recently bought at the Dalton, GA hamfest. Richard responds, though he's had the least experience with MFJ TNCs. There are several possibilities: wrong on-air baud rate, bad connection, wrong dip switch settings, or poor or filtered audio into the TNC. Try using the jack on the back of the radio for the audio. Maybe the radio is not exactly on frequency?

Announcements:

  • The OGG and MP3 feeds for the LHS Music and LHS Up All Night audio streams from the LHS web site have new links, so check your settings. The live streaming feed is mp3, so it works everywhere.
  • The wAVEgUIDES podcast joins the Black Sparrow Media network! Visit blacksparrowmedia.net/join/ if you'd like to add your podcast to the Black Sparrow Media network.
  • Episode renumbering: Ever since naming episodes 18a and 19a, it's been bugging Russ, so they were renumbered to eliminate the letter suffixes.
  • LHS hopes to attend the 2012 Dayton Hamvention in May. Please donate to the cause to help make that happen!

LHS Episode #078: Kubuntu is Bloodthirsty

In this episode of Linux in the Ham Shack, our intrepid hosts put aside idle banter, childish meandering and silly stories in favor of true content, both ham radio and Linux related. All right, that doesn't happen even a little bit. Instead, Richard has a lot of fun telling you all the trouble he has with Linux Mint Debian Edition, all the while mentioning a bunch of other operating systems he's tried recently including Ubuntu, Kubuntu, Crunchbang among others--letting you know what's wrong with all of them.

Then there's some discussion of svxlink, an Echolink client and server application for native Linux environments, Allstar Link, Open Media Vault, contest loggers and a whole bunch of other stuff besides. Ahh, perhaps there is some content here after all. Hope everyone enjoys this episode and can perhaps contribute a dollar or two towards the Hamvention fund. It's coming up soon and we hope to see you all there.

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! 🙂
