LHS Episode #037: Riders on the Storm

There are good things coming up in the world of GNOME and Linux in the Ham Shack has some of the scoop. In this episode we had the good fortune to interview Stormy Peters, the executive director over at the GNOME Foundation. We'd love to tell you all the stuff she told us, but that's what downloading the episode is all about. We wouldn't want to spoil any surprises.

We are currently in migration from Hostican to our new hosting, which includes a mix of BlueCows Technical Services and GoDaddy. During this process, some of the Web site features may come and go, but rest assured everything will be back online eventually. I believe most everything is working now except for the OGG feed and I am working on that. It is very important that everyone switch over to the new RSS feeds in your podcatcher of choice. We wouldn't want you to miss a single episode. Click or hover over the RSS Feed links on the left-hand side of the main Web page for the correct new URLs. And remember, our new e-mail address is info at lhspodcast dot info. That will go to both of us.

Don't forget about the current contests. Don't forget to show up at the Texas Linux Fest in April, the Southeast Linux Fest in June and the Ohio Linux Fest in September. Don't forget to tell 200 of your closest friends about the podcast. Don't forget to donate to the noise gate fund. And don't forget to have fun listening to the show!

LHS Episode #036: Are We There Yet?

We've managed to cobble together another round table discussion for Episode #034 of Linux in the HAM Shack. Thanks to Lord Drachenblut of Ten Buck Review and our party crasher, Jonathan, KB1KIX, for helping us out with this episode.

The format is a little bit different this time based on some feedback from listeners. If you like what you hear or would rather have us go back to the way things were, let us know. We're interested in what you think. Our topic tonight is a thought provoking e-mail that we received before last episode from Jim, N2ENN. Hopefully we've given it an honest appraisal.

Please send us your feedback, your questions and your donations to obtain a noise gate for Richard. Also, enter our two contests for a chance to win real money! And stay tuned for our next recording. We have a very special guest interview coming up. You won't want to miss it.

LHS Show Notes #033

All of us at Black Sparrow Media wish to express our sincere condolences to Richard on the passing of his mother. Our thoughts and prayers go out to Richard and his family. He won't be joining us this time, so we'll carry on with a round table episode.

Contributors:

  • Ted WA0EIR, in snowy Iowa, Andy aka Integgroll on IRC, and Bill KA9WKA join us for a round table discussion.
  • Jay writes in about the Linux Journal episode (#029) and the analysis of the Amazon Kindle and DRM issues. Our panel talks about the Kindle , e-readers in general, and DRM issues. Russ mentions how Amazon retracted a couple of George Orwell titles.
  • Google alert tells us that Linux in the Ham Shack and other amateur radio podcasts are being played over a local repeater by Tony VK7AX for the enjoyment of listeners in SE Australia and Tasmania. Good on ya', mate!
  • LHS was mentioned on Joe's (WN2SYZ) blog. Thanks, Joe!
  • Dave, KG4GIY, posted another mention of LHS at Linux Journal when we talked about software-defined radios (SDR) in Episode 26. Thanks, Dave! Check out the Linux Journal amateur radio content.
  • Chris, Twitter ID WOKNSS, tweeted about catching up on back episodes of LHS. Thanks, Chris!
  • LHS was mentioned at the Low SWR podcast website. Low SWR is an amateur radio podcast produced by Rich KD0BJT and Brady KD0BJS. They're up to eight episodes already! Good job, guys!
  • The Axis wrote to us, Mint Cast, and The Linux Link Tech Show to thank us all for content about the Linux program screen. We're glad you enjoyed it. A possible application might be operating digital modes remotely. (Bonus Show Notes Content: The February 2010 issue of QST has a Short Takes article about the Glentek Radio-to-Ethernet Controller. Glentek has a variety of products to facilitate remote operation of an amateur radio station. -Ed.)

Announcements:

  • Texas Linux Fest is April 10, 2010 at the Monarch Events Center in Austin, TX. You might find Richard or Russ there, so say Hi!
  • Donations: We've achieved our goal! Walter, KV6M, made a second donation (thanks, Walter!), and the remainder was supplied by Beth Lynn Eicher of the Ohio Linux Fest. Thank-you, Beth Lynn! Look for the Linux in the Ham Shack booth at Dayton Hamvention 2010. (Note: the podcast incorrectly identifies Walter as WN3LIF, another Walter that also contributed.  We apologize for the confusion. -Ed.)

Links and Notes:

  • From the chat room, Ronnie K4RJJ, asks what PDAs would work with sound card digital modes. There's i-PSK31 that will allow you to use PSK31 with your iPhone and radio. It's also available via the iTunes store. (Note: I mistakenly said the price was $1.99. The actual price is $5.99. Sorry. -Ed.) There is also some documentation on how to wire the headphone plug for the iPhone for connection to your radio.
  • Ted rants about the use of macros in digital conversations, and the panel discusses.
  • The panel discusses the appropriate power levels for digital modes. Lower power, say less than 35W, is usually enough. There are devices, such as the PSKMeter, that attaches to your transmitter output and, along with software, will display your signal so you can avoid splatter. PSKScope is another program for the PSKMeter that provides additional functionality, such as automatic audio drive level control, but only in the Windows version. A Linux version of PSKScope is available, but does not have the automatic drive level control. The other device discussed is the IMD Meter, which is a standalone device that displays your IMD while you are transmitting. No computer or software is necessary.
  • Next, the panel talks about operating via VHF/UHF satellites. (There's a good introductory article on the AMSAT web site. Randy, K7AGE, has produced several YouTube videos of various amateur radio activities, including this one where he operates AO-51. Another video from the 2007 Dayton Hamvention shows a similar system.
  • Bill introduces the microHAM USB Interface III. (That's the Americas website. There is also a site for Europe. The panel discusses the merits of the device.
  • We then move to a discussion of Linux Mint 8 "Helena".
  • Bill rants about Yaesu microphones on their VHF/UHF radios.
  • Russ talks about some cloud computing applications: Ubuntu One and Dropbox. The panel discusses the relative risks and advantages of using such services.

Music:

  • "Don't Go" by TenPenny Joke from the album "Ambush on All Sides".
  • "Mirror of Humans" by Amity in Fame from the album "Dinner for One".

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,

-Bill, KA9WKA
