  • Matt, KC8BEW, tells us about a new Linux forum at Linux Journal for amateur radio topics.  The January, 2010 issue of Linux Journal has several amateur radio related articles.  Add  https://www.linuxjournal.com/ham to your bookmarks.  Look for an interview with a couple folks from Linux Journal on the episode to be recorded on January 5, 2010.  And thanks to Kent, VE4KEH, for the plug in the forum over there.
  • Kent, VE4KEH, sent in an audio segment, to be included later in this episode.  If you'd like to submit an audio segment, please send it in .ogg or .mp3 format, if possible.
  • Another message from Kent suggests a topic for a future show about installing distros from live .iso files to a flash drive with persistence.  (Check out the Pen Drive Linux site.)
  • Rich, KD0BJT, and his son Brady, KD0BJS, have started their own podcast, called Low SWR.
  • A WordPress blog by Gary, KE2YK, references an article by Martin, AA6E, about Linux and amateur radio.

LHS Episode #029: Evil Empires

deathstarIt occurs to me that having an episode discussing evil empires during a celebration- and holiday-filled time of year might be a bit ironic but that's just how things turned out.

Thank you to everyone who has so generously donated to the podcast so that we might have a presence at the upcoming Dayton Hamvention in May, 2010. It was an idea spawned at Ohio Linux Fest in September, 2009 and we've come a long way since then. Every contribution helps and we hope you'll continue to support Linux in the HAM Shack in the future. We also hope to provide timely and essential information to amateur radio enthusiasts and computer users for a long time to come.

From our world to yours, have a Merry Christmas, Happy Hannukah, Joyous Saturnalia, or just a good ol' time--whatever your "thing" might be. We hope you enjoy our latest installment of the podcast, and please: Keep spreading the word. Every month our audience grows, and we predict world takeover by 2014. Well, maybe not, but we are talking about evil empires after all...

Xastir and Linux Mint

Installing Xastir in Mint

Ben, VK5JFK, left a comment on my review of Linux Mint at the Linux in the Ham Shack web site, asking if I had installed Xastir under Mint.  I had not, but since Richard talked about Xastir in Episode 23, and Linux Mint is the "official" distribution for Linux in the Ham Shack, I thought a brief how-to article might be useful to our listeners.

In fact, installing Xastir in Linux Mint is fairly easy.  Here's a step by step procedure:

  • Launch the Synaptic Package Manager
  • Select the Amateur Radio (Universe) repository
  • Click on Xastir in the list - version 1.9.4-3 was available as I did this
  • Click on Apply - a bunch of dependencies were selected, and after approving that list, off it went.

A few minutes later (over a DSL connection) the installation was complete.

The first (and only) problem I encountered was that the installer did not create an entry in the Mint menu.  To remedy this, I clicked Menu, Preferences, Main Menu.  This utility allowed me to add a new menu category I called Amateur Radio, and a new item in that category that I creatively called Xastir.  The associated command is "/usr/bin/xastir".  After logging out and in, the new menu item appeared.

Before running Xastir for the first time, I opened a terminal and entered the command:

$ callpass ka9wka

and the computer responded:

Passcode for ka9wka is 19125
$

Of course, you will use your callsign and you'll receive a different passcode.  You'll need that number when configuring the interface.  No, the callsign is not case-sensitive.

After running Xastir, you must perform some configuration, as Richard discussed.  For this test, it was simply a matter of defining my location and adding the Internet interface.  When you launch Xastir the first time, it will automatically open the "Configure Station" dialog, but you can return to that by clicking File, Configure, Station.  Here I entered my callsign and location.  I left the rest of the options at the defaults.

Next, I clicked the Interface menu option, then Interface Control.  This brings up an empty list of configured interfaces.  I clicked Add, chose "Internet Server", and clicked the Add button. The "Configure Internet" dialog box appeared.  I entered 19125 into the Passcode field (see above), and "r/42/-87/500" (without the quotes) into the Filter Parameters field.  This filter says, I believe, show all stations within a radius of 500km of 42 degrees N and 87 degrees W.  Modify to suit your location and preference, and click OK.  Finally, still in the Interface Control dialog box, I clicked Start All.  The status changed from DOWN to UP, and I closed the dialog box.  In a few moments, stations began to appear on the map.

There are a lot more options in Xastir that I haven't explored here.  For example, if you're planning on installing this on a laptop with a TNC and GPS device attached, you'll need to add interfaces for those as well, and you'll probably want to add a more detailed map for your area.  For now, this should get Xastir running under Linux Mint with a minimum of time and bother.

73,

  • A Google alert says the LHS website showed up in linuxzine.com, probably because of our sponsorship of Linux Mint.
  • You can leave feedback via our toll-free telephone line at 888-455-0305.

Links and Notes:

  • Richard talks about using an old Dell Latitude laptop for mobile operations. After many trials and tribulations and resetting the BIOS, he managed to install Xubuntu, and has D-RATS installed.
  • Russ installed Ubuntu 9.10 on a machine. He tried 64-bit Linux Mint 7, but it failed.
  • Richard wanted to run DSL or Puppy on the Latitude. DSL booted, but he couldn't get the network card to work.
  • From the chatroom, N3JIM asks what virtualization software Russ is using. Currently, VMWare Server 2.02, but it doesn't play nice with newer kernels. So, Russ is planning on moving to Sun's VirtualBox.
  • Matt points out that Ubuntu will remove Gimp from the default installation beginning with Ubuntu 10.04.
  • Short Wave Listening, a topic suggested to Russ at Ohio Linux Fest.
  • Receivers: Ten-Tec RX-320D, a PC-controlled, shortwave receiver. Ten-Tec supplies Windows software, but there is a Linux program, too.
  • An article describing the receiver and it's application.
  • Other radios are available from Yaesu, Icom, Kenwood, and C. Crane.
  • Russ talks about the Radio Shack DX-440 shortwave receiver he used (aka Sangean 803A).

  • Software: MultiMode 5.9.2 (for Mac OSX), fldigi, Radio Explorer.
  • Things to hear: Numbers stations, Letter stations.
  • Antennas: very similar to what you would need for a transceiver. Random wires and tuned dipoles, will work, too. Look for a receiver that has an external antenna jack.
  • Where to listen: Amateur radio bands, international broadcast bands.
  • QSO Radio Show can be heard Tuesdays from 05:00PM to 07:00PM ET, 2100 to 2300 UTC at 7415KHz (WBCQ radio).
