Show Notes #097

Introduction:

  • Welcome to another episode of Linux in the Hamshackedness, where the Chocolate Shake Fairy visits Richard.

Announcements:

  • LHS now accepts micropayment donations via Flattr. It's been successful for the Linux Outlaws guys, so we're giving it a try here.
  • We now have a countdown timer on the Web site that shows the time remaining until the next live recording. Of course, now that we're recording on Wednesdays, we've decided to move back to Tuesdays. That will happen in January. Keep an eye on the web site for the dates. (Tuesday, January 8, 2013, as of this moment.)
  • We also have a Google Community for Linux in the Ham Shack. It's a great method for leaving feedback, show suggestions, questions, hate mail or anything else.
  • The Dayton Hamvention 2013 will be coming up soon, so we've added the donation thermometer to the website. Please make a donation and help send LHS to Dayton again in 2013.
  • Sign up for the LHS mailing list, too.
  • Gnorman has a bio on the LHS About Us page.

Topics:

  • Raspberry Pi in the Ham Shack
    • Russ has been working on getting an Echolink node running on his Raspberry Pi.
    • He's chosen Raspbian as the operating system, which is based on Debian Wheezy.
    • Installation consists of downloading the iso, using dd to copy it to a secure digital card (SD flash memory card), booting the Raspberry Pi with the SD card, and following the prompts to install.
    • VK2MEV has posted instructions for configuring a Raspberry Pi as an Echolink node.
    • So far, Russ has Raspbian installed, as well as svxlink and qtel, but has not yet connected it to the usb sound card or attached it to his Rascal GLX interface to control the radio. Another option would be to use the Pi's GPIO bus to control the radio instead of a digital mode interface.
    • VK2MEV also has a page describing WSPR on a Raspberry Pi. (Another page is VK2MEV's blog on WSPRnet.)
    • Ted, WA0EIR, says he thinks some folks have his PSK31LX program running on a Raspberry Pi.
    • Russ mentions that there is a Slackware build for the Raspberry Pi.

Feedback:

  • Cory, KD0QEA, asks if there are any "hangout" radio frequencies for LHS hosts and listeners. Well, Cory, there are none due to lack of time for the hosts to get on the radio. However, perhaps our listeners would like to establish an LHS net. Email your suggestions for bands, frequencies and times and we'll announce them on the podcast. When Russ gets his Echolink node/Raspberry Pi running, he'll be there more often. The node number will be 54711 (LHS11 on the telephone pad).
  • Doug, N6LMX, left a voice mail about the Raspberry Pi. He has one and wonders which ham radio apps can be used on the Pi. He's also using Raspbian as the operating system. Doug will be attempting to create a media center with his, as well as ham radio applications. Russ suggests running the Pi headless and using ssh from a smartphone or tablet to access it. That would avoid having to carry a monitor and keyboard around with the Pi. It's likely that most of the popular Linux ham applications, such as fldigi, would work fine with the Pi, though you may need to compile them yourself. As for the media server idea, the Pi may not be quite powerful enough. Raspbmc is based on XBMC, and might be the best option. Ted, WA0EIR, has several Linux ham radio applications that should work quite well on the Pi. Richard also wonders if there are folks running APRS on the Pi, and there's at least one. Thanks for the voice mail, Doug. We appreciate it.
  • Dave, M0DCM, has been catching up on the show, and responds to episodes 95 and 96. He uses 75-ohm coax as a feedline with a 1:1 balun to horizontal and vertical dipoles, and is able to bypass his tuner on 21 and 24MHz. He goes on to describe his Linux and radio activities. Thanks, Dave.
  • Thanks to everyone who sent happy birthday messages to Russ.
  • Gorkon, aka Joel, says there may have been a problem with the ogg version of episode 96. Russ will take care of it if he finds the problem.
  • Mike, from Sugarland, TX, has been trying to use N3FJP's Amateur Contact Log (ACLog) program for logging, presumably under WINE, but it crashes and he wonders if anyone else has had any experience with this. If any of our listeners have tried ACLog under Linux, let us know, or respond on the Google+ LHS community. Russ suggests forcing WINE into 16-bit compatibility mode.

LHS Episode #097: Sheer Hamshackedness

shack-03Welcome once again to the Wonderful World of Linux in the Ham Shack. As indicated in the title, this episode is full of Sheer Hamshackedness. If you're unsure what that is, we encourage you to pour yourself a nice glass of dark beer or a 100-proof spirit of your choice, put on your headphones and immerse yourself in the pure hedonism that is LHS. And if you believe any of that, we have a large vehicular conveyance over the East River in New York City up for sale as well. Anyway, we talk a little bit about Raspberry Pi computing, APRS, WSPR, Echolink, svxlink, Qtel and a bunch of other stuff in this episode. Hope you enjoy, as always.

Show Notes #094

Introduction:

  • No music this episode.
  • It's the night before Halloween and we're off to another spooky episode of LHS with our hosts starting with a ramble about horror movies. It's a trick AND a treat!

Announcements:

  • Please consider donating to the podcast or subscribing for #20/year. Also, the free Black Sparrow Media app is at risk of disappearing unless our listeners are willing to provide $15/month to keep the download site alive. Please contact us if you can help.

Topics:

  • Creating a desktop wallpaper slideshow in GNOME:

    It's actually a built-in feature of GNOME. Briefly, here are the steps:

    • As root, create a new directory in /usr/share/backgrounds (any name you want).
    • In that directory, place your desired background images (or links to them).
    • There's already a directory in /usr/share/backgrounds called cosmos which you can use as a guide.
    • Copy background-1.xml from the cosmos directory into your new directory and edit it to specify your images.

    More information can be found in this askubuntu thread. Be sure to read through all the comments.

  • Richard points us to one of many articles about ham radio operators helping out during and after Hurricane Sandy. Our sympathies to the victims of hurricane.
  • More about EchoLink and Linux: Richard found the CQiNet project, which includes two applications, Echolinux (an EchoLink client for Linux) and The Bridge, an iLink/EchoLink compatable conference bridge. Of course, there is still the svxlink package, which includes the Qtel Echolink client.
  • C'mon, people, where are my Raspberry Pi suggestions? Russ is still looking for good uses for his Raspberry Pis. Send your suggestions!
  • Google Webfonts are open source fonts that can be embedded in Joomla, WordPress and others, embedded in CSS, or with Javascript. Visit Russ' blog page for an example of Google Webfonts in action.

Feedback:

  • David, KE0AZ, sent an email about our discussion of antennas in Episode #091. He's opting for a used 4BTV vertical.
  • Tim, KI6BGE, in response to Richard's computer power supply repair in Episode #092, shares his success story involving a printer repair he attempted.
  • Scott, N8VSI, sent this audio report on his experience as the LHS ambassador at the Ohio Linux Fest. (We talked to Scott in Episode 93.)
  • Harrison, VE2HKW, made a donation to the Black Sparrow Media app server fund. Thanks, Harrison!

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!
