  • Look for Russ on Shortcast #0003 of the Fresh Ubuntu Podcast.
  • LHS has a new audio promo for the show! So far, it's only been played by the Working in the Open podcast.
  • Jerry, KD0BIK, again mentioned LHS as a good Linux podcast on a recent episode of The Practical Amateur Radio Podcast. Thanks, Jerry!
  • We received no entries for our logo contest, so Russ bought one! Check out the new website design and logo and let us know what you think. LHS merchandise is coming soon!
  • Russ and Richard will be at the 2010 Dayton Hamvention, May 14-16, in booth 265 in the North Hall (NH0265). We hope to see you there!
  • Russ will also be at the SouthEast LinuxFest, June 12-13, 2010, at the Marriott at Renaissance Park hotel in Spartanburg, SC. Russ will be delivering a talk on ham radio and Linux.
  • Richard has a noise gate! It was a gift from Jim, W9GNG. Thanks very much, Jim!
  • Due to problems with the existing service provider, the LHS website has moved to lhspodcast.info. If you have a web page with a link to Linux in the Ham Shack at blacksparrowmedia.com/lhs, please change it to lhspodcast.info. Blacksparrowmedia.com will be going away in the near future.
  • The other show, Resonant Frequency, is still on hiatus, but those links will be changing, too. Watch this space for more information.
  • Look for LHS in IRC at irc.freenode.net, channel #lhspodcast. Join us!
  • LHS, along with other podcasts on the Tech Podcasts Network are now available on the Boxee and Roku media players.


  • Richard and Russ discuss XDX, an X-windows client to connect to a DX-cluster, written by Joop Stakenborg, PG4I.
  • In Linux Mint, Ubuntu, or Debian, you can use
            apt-get install xdx

    to install the program. Setup is simple:

    • Click Settings, then Preferences. Enter your call sign, and if you have your radio connected to the computer and it can be controlled by the hamlib utilities, click the "Enable hamlib" checkbox. Click OK.
    • Click Host, Connect... and enter the information for your favorite DX cluster. Visit the AR-Cluster Node List web page to find one near you. Russ used k2can.net, port 4000. Click Connect. (If a port is not specified, try 23.)
    • Type your call sign and press enter to log in. The cluster may ask a few questions to confirm your name and location.
  • Spots appear in the upper window pane. Prompts from the host appear in the middle pane, and your entry goes in the bottom pane.
  • If you wish to send a spot, look in the help file for examples such as:
            dx 28002.2 xz7a worked with 80m dipole!!
  • In general, it's "dx" followed by the frequency, the station you've spotted, and a comment.
  • Other commands are documented in the help file.
  • Another web page that lists cluster nodes is www.ng3k.com/Misc/cluster.html.


  • Along with the noise gate, Jim, W9GNG, sent a letter expressing his appreciation for the podcast and tells us a bit about his background.
  • Jim, N2ENN, writes a response to our discussion of his email back in Episode 034, again condemning the state of drivers in Linux. Thanks for the response and discussion points, Jim.
  • Thanks to Gary, KE2YK, for mentioning the podcast at every opportunity, and his donation! Donations will be applied to hosting costs.
  • William (Bill?), KB9TMP, recently discovered the podcast via Resonant Frequency. He's also a new Linux user, but is having trouble finding help, and he comments about "old" hams and "new" hams. Our hosts respond.
  • Danny, not currently a ham, is blind and studying for his license test. He'd like to use Linux with Orca and wonders what hardware is best and what other Linux programs for ham radio are suitable for the blind user. Check out the Courage Center Handiham System and Frostbite Sytems. There is a version of Ubuntu for the visually impaired called Vinux, and a version of Arch Linux for the blind. Ask around your local amateur radio club, too.
