  • [audio:https://bsmarchive.info/lhs/mp3/lhs102.mp3]

Introduction:

  • Rob from the MintCast podcast is on the show tonight filling in for the nomadic and enigmatic Richard.

Announcements:

  • The 2013 Dayton Hamvention is coming up May 17-19 in Dayton, Ohio. We are still in need of donations. Please keep 'em coming.
  • The Wouff Hong Podcast, member of the Black Sparrow Media Network, have released their first episode. If you don't subscribe to the BSM aggregate feed, you can find them at the link above. Good episode, and they mention LHS.
  • Rob and Russ use BeyondPod on Android as a podcast manager.
  • Roy, KK4ATD, will be in Atlanta at RARSfest as an ambassador for LHS. If you're anywhere near Raleigh, NC on Saturday, March 30, 2013, stop by and say hello. [LHS will NOT be present at RARSfest this year. Sorry for any confusion. -Ed]
  • The sponsored ads in the right column of the LHS web site actually make us a not insignificant amount of money when you click on them. If you want to help us out without donating your own money, please click on an ad when you visit our site. We get money in our donation box, and you don't lighten your own pockets. Thank you!

Topics:

  • Visit KE8P's blog. One of the articles documents using a Raspberry Pi as a temperature monitor.
  • KK4ATD has developed Hamux, a 64-bit, CentOS-based Linux distribution with ham radio applications. This is a "live" CD image, so you can boot it from CD and try it before installing. At 698MB, it just barely fits on a CD.
  • Our hosts embark on a brief digression about Douglas Adams.
  • Slow Scan TV (SSTV)SSTV is a method of sending still images using radio frequencies on the HF bands. FSTV (fast-scan TV), which is typically done on VHF and UHF frequencies at distances up to a couple hundred miles, is similar to broadcast TV.In order to operate SSTV, you'll need a radio (and a license to transmit), a computer, a sound card interface to connect them to each other, and software. For Linux, we have QSSTV. The current version is 7.1.7, released on January 4, 2012. It is compatible with the Ham Radio Control Libraries (hamlib) for controlling the radio.Russ gives a brief overview of the various configuration options and interface of QSSTV.
  • Rob is not a ham, but has considered obtaining his license. Unfortunately, he lives in an area with deed restrictions that prohibit outside antennas. What are his options? There are several resources on the web for ham operation with antenna restrictions. Some of these are:

    Though in Rob's case, with aluminum foil-lined roof tiles, attic antennas are not likely to work very well.

    Other possibilities: using EchoLink, IRLP, operating mobile or portable. Perhaps tossing up a temporary wire antenna in the back yard, operate, then take it down.

    Rob and Russ discuss the various options, potential for TVI, and VEC testing opportunities.

Feedback:

  • David, KE0AZ, writes to say he's sorry to see Richard to go, but will continue to listen.
  • Frank, K4FMH, would like to see more technical content in future episodes.
  • W. Lynn writes to say that the Belton HamExpo will be April 20, 2013 in Belton, TX.
  • Gary, KE2YK, will miss Richard, too. He also appreciates the mention of Linux Mint 14 as it reminded him to give it a try.
  • Pete, VE2XPL and the host of the wAVEgUIDES podcast, sends his congratulations on 100 episodes and best wishes for Richard.
  • Gary, KE2YK, also sent comments about episode 101, including a link to his review of the Raspberry Pi.

LHS Episode #102: Run, It’s George Lucas!

Posted on by Russ Woodman

darth_sidiousHere we are, two episodes past the Richardocalypse and the calendar hasn't run out yet! This time around, I'd like to thank Rob from MintCast for once again stepping in to be a co-host on the show, filling in the left big toe of the shoes once worn by The Richard himself.  Since I barely fill a pinky toe, myself, that's really saying something. In this episode we go a little ham nutty with Linux thrown in. Topics range from slow-scan television to licensing requirements to Rob asking, "What do I need another damned hobby for??" That question and many others answered in this fabulous installment of Linux in the Ham Shack.

Introduction:

  • The 10th Annual Ohio LinuxFest will be held September 28-30, 2012, at the Greater Columbus Convention Center in downtown Columbus, Ohio.

Show Notes #077

Posted on by Russ Woodman

Introduction:

  • We're recording live, with music played as we record. Our guest tonight is Harrison, VE2HKW, from the MintCast podcast.

Announcements:

  • The Dalton Hamfest will be in Dalton, Georgia on February 25, 2012. The LHS Ambassador is Ronny, K4RJJ. This has probably come and gone by the time you hear this.
  • The KARC Hamfest will be held in Marietta, Georgia, March 17, 2012. Our LHS Ambassador is again Ronny, K4RJJ. Thanks, Ronny!
  • The Northeast Linux Fest will be in Worcester, Massachusetts on March 17, 2012. We're still looking for an LHS ambassador for this event. Contact us at ambassadors@lhspodcast.info if you'd like to help.
  • Some of you may have noticed that the LHS web site has been down occasionally. For some reason, the server locks up. We can't tell if it's a denial of service attack, or an improper configuration, but we're working on it.
  • Paul, KE5WMA, in the chat room, reminds us of the Acadiana Hamfest on March 9, 2012, near Lafayette, LA., and the New Orleans Hamfest on March 24, 2012.
  • Happy Mardi Gras!

Topics:

  • Linux Utilities - Russ introduces us to some GNU/Linux utilities that provide information about your Linux system's performance.
    • top shows a list of the processes running in descending order of resource consumption.
    • iftop allows you to monitor connections to your machine and the bandwidth used by each.
    • ifstat reports the amount of data passing through the interfaces every second, or other interval. For example, ifstat -i eth0 10 1 would report how much data moved through the first ethernet port in 10 seconds, and only do this once. Handy for capturing such information in a script program.
    • iotop shows what processes are the top disk I/O users.
    • All of these are command line utilities. Press Q to exit. Check the man pages for other keystrokes that can be used while the utilities run.
  • Interview with Harrison, VE2HKW
    • Harrison, VE2HKW, is a recent ham radio licensee and describes his introduction to the hobby, what he likes and doesn't like, and provides an overview of the Canadian amateur radio licensing structure.
    • Harrison is also a member of the Covey Hill Amateur Radio Club (CHARC).
    • Check out Harrison's blog and pictures of his ham shack.
