LHS Show Notes #066

Posted on by Russ Woodman

Introduction:

  • Richard is still in the process of moving, but did get his WinLink rms gateway running as described in a previous episode.

Announcements:

  • Jay Forrest has lauched The Linux News Podcast. The podcast will focus on topics such as software freedom, Linux development, Open Source software, Android and mobile devises, security issues, and Linux distribution releases. Our hosts offer their opinions.
  • Ohio LinuxFest will be held in Columbus, Ohio on September 9-11, 2011. (Note: Russ will not be there, but maybe YOU can represent LHS. Visit the web site and look at the Ambassadors page to learn how.)
  • Texoma Hamarama will be October 21-22, 2011 in Ardmore, OK. Richard might be there, so if you're in the area, look for him!

Topics:

  • Our hosts discuss the ARRL statement regarding HR 607, "Broadband for First Responders Act of 2011". This bill provides for the re-allocation of the 420-440 MHz band, calling it part of the "Public Safety" spectrum. This is not the case, and we should contact our representatives and voice our opposition to this bill. The ARRL offers sample letters you can send to your representatives.
  • Richard and Russ talk about various amateur radio programsfor Linux offered by Ted, WA0EIR.Russ built them all from the available source code on his Linux Mint Debian Edition 10 computer. In order to do so, he installed a number of development libraries:
    • libmotif-dev
    • libxmu-dev
    • libxpm-dev
    • libxbae-dev

    These are header files necessary for the compiler to properly build the programs.

  • Each program requires the following commands to compile and install. Change to the directory containing the program and type: 
      ./configure
  ./make
  ./make-install

    (You may wish to be root to perform the make-install command.)

  • TWLOG - A basic QSO logging program. Useful for day-to-day logging, but not recommended for contest logs. It will export to ADIF. It requires the Xbae Matrix Widget.
  • TWPSK - A simple bpsk/qpsk program. Co-written with Hansi, DL9RDZ
  • TWCW - A Morse Code trainer that also allows keyboard CW operation.
  • TWCLOCK - A world clock application that will also automatically send a CW identifier every 10 minutes.
  • Check the /etc/X11/app-defaults directory for the "X resource" files to change the configuration options for these programs. For example, in that directory is a file called twclock that contains the callsign transmitted by TWClock.
  • PSK31LX - A curses-based PSK31 program, so it runs in a terminal window or directly in a terminal session. For help, a man page is included. (Type "man psk31lx".) It makes use of the arrow, control, and function keys. You can choose the audio and serial devices with command line parameters at start. Configuration parameters are stored in your home directory in the file .psk31lx.ini.

Feedback:

  • Don, WS4E, asks for Internet resources for handicapped amateur radio operators. He's familiar with the Handiham  organization, but wonders if there are others.There are many newsgroups and mailing lists dedicated to hams with disabilities. A Google search should return several. The Canadian National Amateur Radio Society site Amateur Radio for the Disabled, has several useful links. Richard mentions Lighthouse for the Blind. The ARRL has a page listing several articles. There's also a Facebook group, Blind Amateur Radio Operators.
  • Petr, OK2CQR, the author of CQRLOG, responds to Torsten's (K5TOR) problems installing CQRLOG on a 64-bit machine: CQRLOG already has native 64-bit version. There is no need to install the 32-bit version. You can use the ppa at launchpad.net with packages for Lucid, Maverick, Natty and Oneirc. Version 1.2.1 will be part of the Oneiric release as well. More information is here.

LHS Episode #059: Orca and Outtakes

Posted on by Russ Woodman

Welcome to Episode #059 of Linux in the Ham Shack. On this edition, we talk with Jonathan Nadeau of Frostbite Systems about Linux for the sight impaired. Jonathan, being a blind Linux user, has overcome many challenges when it comes to using his favorite operating system and he shares with us the ins and outs of accessibility on Linux systems. There is a Linux distribution dedicated to blind users called Vinux, along with an accessible version of Arch called Talking Arch. Even newer versions of Slackware are jumping on the bandwagon with a Speakup enabled installation kernel.

This is also the first episode of LHS with a blooper reel left in at the end. Listen all the way to the last so you don't miss out on any of the fun. Many thanks to Jonathan for his time and expertise, and many thanks to our listeners for making our show so fun to do.

  • 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.

Feature:

  • 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.

  • 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.

LHS Episode #038: XDX ‘n Stuff

Posted on by Russ Woodman

The season of Linux fests is now under way. The Texas Linux Fest took place a couple of weeks ago. By all accounts, the turnout was excellent, the educational opportunities were plentiful and fun was had by all.

Oggcamp in the UK is next on the list. Then there will be ham fests and Linux fests all over the country and the rest of the world for the rest of the spring, summer and early fall. Linux in the Ham Shack will be represented at the Dayton Hamvention in May and at the Southeast Linux Fest in June. I'm also trying to start a new Linux fest called the Mid-America Linux Fest which will be held in early November. It's possible that could be November of 2010, but it's more likely to be November 2011. If you want more information about the Mid-America Linux Fest or are willing to volunteer your time or services, please check out the Web site at https://midamericalinuxfest.org.

And yes, I know this episode of Linux in the Ham Shack is late. Life has been very busy of late and I think all of our listeners for your eternal patience. We hope to see you at the live recording of Episode #037 on April 27th at 8:00pm.
