This is a short introduction to Linux for Amateur Radio Operators showing a few things that are available for Amateur Radio.

Announcements:

• Thanks, again, to Gamma Leonis for the opening and closing music for the show.
• LHS Merchandise is available at PrintFection and Cafe Press. LHS items make great Christmas gifts! Or, make a donation by clicking the Donate link on the website. Donations cover such things as the telephone lines, server fees, and more. Thank you!

Topics:

• Articles seem to be popping up at www.amateurradio.com designed to get us talking about Linux and Amateur Radio. The latest one is by Anthony, K3NG, self-proclaimed radio artisan. Our hosts discuss his assertions that:
  • Ham Radio Deluxe, DXLab, and N1MM software all beat any Linux offerings. (Note: Russ has found that both Ham Radio Deluxe and N1MM logger will run under WINE in Linux. DXLab, on the other hand, will not.)
  • There is more amateur radio software available for Windows than Linux.
  • CQRLOG is an adequate Linux program for casual logging, but not great for contesters.
  • “Quite simply, if one intends on using Linux exclusively in the hamshack they have to lower their expectations and requirements for logging and are between a rock and a hard place when it comes to contesting.”
  • He does praise fldigi, but still claims Windows software is better.
  • In summary, he thinks hard-core contesters may wish to stay with Windows. Our suggestion: run Linux and write a program that works better!
• Russ talks about his success with WSPR and Echolink.
• He found that instead of using “dpkg -i” to install the latest Debian WSPR package, use “dpkg -x”. You’ll extract the files to the current directory. You then run the program from a terminal session in your home directory using “./wspr”. If you run it that way, instead of letting it install, it seems to work a lot better. The Gnome launcher doesn’t seem to work with that sort of installation, but running it from a terminal works well.
• Russ has Echolink running under WINE v1.13. This version of WINE was chosen for it’s native support of PulseAudio, which made configuring EchoLink much easier. Russ’ node is on 146.225MHz simplex, Echolink node 54711.
• Russ then tells us why Echolink and IRLP are different and why IRLP might be “better.” (Hint: Echolink may not have an amateur radio anywhere in the link, while IRLP definitely uses a radio somewhere in the link.)

Feedback:

• Scott, HL2/AD7MI, sends his appreciation for the discussion in Episode 50 of his blog entry about his Ubuntu installation, and adds a note about problems with running CQRLOG under 64-bit Linux. He says you can install CQRLOG on a 64-bit machine, but it will only work with the 32-bit version of hamlib. Unfortunately, that breaks 64-bit fldigi, which expects the 64-bit version of hamlib. This issue has been reported on both the linuxham Yahoo group and the CQRLOG forum. Scott has also successfully installed Xastir, and is looking forward to receiving a MicroHAM III interface.
• Matt, KC8BEW, asks “What is a good and easy Linux distribution for a web server?” Russ recommends a plain vanilla installation of Debian server, without the X-windows environment, and either Apache or nginx (a light-weight web server).
• Dave, M0DCM, tells us of his success running fldigi and CQRLOG under Ubuntu 9.10 on an Acer Aspire A0751h netbook. Well done, Dave!

• A very generous donation was received from Gerrit R. Thanks, Gerrit!

Hello, everyone. We're coming to the end of another year and the world is aglow with holiday spirit. With that in mind, we bring you the second-to-last episode of Linux in the Ham Shack for 2010. We will have one more recording and release before the end of the year, so don't miss out on our holiday extravaganza.

We no longer broadcast video via Ustream, but we do have a live audio feed. Just point your streaming audio player at http://stream.lhspodcast.info:8008/lhslive starting about 30 minutes prior to air time (8:15pm CT). You can join in the chat room scene as well with your favorite IRC client. We are at irc.freenode.net in channel #lhspodcast. The channel is available 24/7, even when we're not doing a live show. Join in when you can and chat with other LHS listeners. During the live show, #lhspodcast becomes our chat room and our live connection with YOU.

Cheers and 73 from the LHS Guys

We have topped 40,000 downloads! Thanks go out to all of our listeners and live webcast attendees for making Linux in the HAM Shack as popular as it is. Give yourselves a huge round of applause. We're also well on our way to our donation goal of $750 so we can buy booth space and Internet access at the Dayton Hamvention in Dayton, Ohio, in May of 2010. Thank you for all of your donations. Please keep them coming as you're able to send them in!

In this episode, we address listener feedback and comments, and then in a burst of inspiration invite listeners from the chat room to come onto the program for a lively and very fun roundtable discussion. Topics were varied, from portable antenna design, to life without Red Bull; from the HAARP VLF array in Alaska to D-STAR, PACTOR and other digital ham radio communication modes. And since I was on meds and Richard was off his, things got a little crazy towards the end.

We hope you enjoy this episode of Linux in the HAM Shack. Please leave us comments or questions on the web site or via voice mail at 888-455-0305. And send your best wishes to Bill, KA9WKA, who has taken on the responsibility of getting LHS's show notes out in a timely fashion. Thanks, Bill. You're a lifesaver!

Back from Baltimore and ready for more ham radio, Linux and Linux in the HAM Shack. I had originally planned to get this episode out before I left for the Large Installation System Administration conference in Maryland, but it didn't work out that way. I even brought all the audio with me to assemble the podcast during my off time at the conference. It turned out there wasn't any off time, so I wound up having to finish up when I got home. That being said, I have to admit this is my favorite episode so far.  It seems like Richard and I are finally getting the hang of this podcast thing. We truly appreciate all our listeners. It makes the time, effort and money of putting out this program worth it.

In Episode #024, we bring you some final wrap-up from Ohio Linux Fest, including interviews with ham radio operators, Linux users, Beth Lynn Eicher from OLF, members of the Drupal project and more. We answer listener comments and questions, of which there are many, and I talk about my getting back on the air and include my new experiences with digital communication via ham radio, from PSK to IRLP. Grab a drink, sit back and enjoy this episode of Linux in the HAM Shack. And if you have a spare couple of dollars, drop them in the can so we can bring our show to the national ham radio convention in 2010: The Dayton Hamvention.
