LHS Episode #055: FLDIGI In Depth

Welcome to the first Linux in the Ham Shack for the new year! 2011 is upon us and we wanted to present our listeners with a fantabulous new show. That’s what you’re going to get. We were able to entice the lead developer of FLDIGI, W1HKJ, to come on the program and give us his personal insights into this best-of-class Open Source amateur radio software.

Yes, we know we talk about FLDIGI a lot in our program. We try not to beat it to death. But if you use this program, there is so much information packed into this interview, you’re going to learn at least a dozen things you didn’t know about FLDIGI, even if you use it every day. So sit back, strap in, and join us on this thrill-packed ride into the dark and seedy innards of your favorite digital mode app. We were impressed; you will be too.

LHS Show Notes #053

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!

LHS Episode #053: Windows in the Ham Shack?

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

LHS Show Notes #052

Episode 50: A milestone!

Announcements:

Topics:

  • Scott, AD7MI, posted an article on his blog about moving to an all-Linux ham shack. Richard and Russ discuss the article, including Shackbox Linux, Ham Radio Deluxe, CQRLog, and more. Ultimately, Fldigi and CQRLog resulted in “100% Linux Nirvana”.
  • Scott also asks what we think would be the ideal Linux-based ham shack. Russ describes his shack, which he thinks IS ideal. Our hosts then discuss various soundcard interfaces:
  • Most sound cards work fine, and Russ recommends the SoundBlaster series over all, but suggests staying away from the SoundBlaster Audigy SE (model CA0106) sound cards as they don’t seem to work well (or at all) under Linux.
  • Richard likes his Yaesu FT-897D. Most modern rigs allow a fixed-audio level connection to the computer sound card, as well as computer rig control. Russ has the Kenwood TS-570D, and it, too, is well-supported in the Linux ham libraries.
  • Russ and Richard discuss the fact that most hams don’t log VHF/UHF contacts, other than in contests or toward an award.
  • The FCC, created by the Communications Act of 1934, included the requirement to maintain a log book in the rules. Sometime between 1983 and 1986, this requirement was dropped as the FCC determined that the information was of little use to them. (If someone can point us to a reference that identifies when the exact rule change occurred, please let us know. I was unable to find the specific change online. -Ed.)

Feedback:

  • Leif, KC8RWR, writes that Internet over EME (earth-moon-earth) isn’t likely to work due to the high latency involved. (This may be in reference to a comment in Episode 48.) NASA and DARPA are involved in a Deep-Space Internet project.
  • Leif also asks “Isn’t Morse code dead?” and wasn’t it replaced by “Gerke Code”? Our hosts discuss.
  • Craig, KB5UEJ, writes that he thinks Russ’ audio is louder and muddier than Richard’s in episodes 46 and 47. Russ agrees that the audio on a few of the recent episodes did suffer, but should be much improved now.
  • Grant, KC9SJQ, comments that he doesn’t see a link to Russ’ screencast about SSL anywhere. Yes, it somehow disappeared, but Russ is working on it. He’ll either find the file or redo it.
  • William, KB9TMP, sends his comments about Episode 48 where we discuss KE9V’s article that questioned the relevance of amateur radio.
  • Craig, KB5UEJ, commenting about WSPR, says that you can run less than 5W on an FT-897 by reducing the audio drive from the computer to the radio. Richard points out that the reduction is often not uniform across the audio freqeuncies used, so some intelligibility may be lost. He had that problem with packet, but he’ll try it with WSPR.
  • Matt wants to know the artist and title of a song in Episode 48. The song was “Endline (Choose Nothing)” by I Am Not Lefthanded from the album “Yes Means No”. Check out the show notes for Episode 48 for a link to the song.

LHS Episode #013

We come to Episode #013 of Linux in the HAM Shack. This one is not for the faint of heart or the triskadecaphobic. Our last couple of episodes have generated a lot of feedback so we spend the first and last segments of the show talking about everyone who sent us comments and answering questions wherever possible. In the middle, we manage to squeeze in some information ham radio and Linux information about getting your radios connecting to your computer for rig control, testing with grig and integrating logging and rig access with fldigi.

We’d like to thank the multitudes we had in the chat room for the live broadcast of Episode #013. It was our best turnout yet with more than 25 participants from all over the world. We’d like to encourage everyone to jump in on the next broadcast, which will be on May 13th at 0100Z. The LHS release schedule is being pushed back a week because I will be out of town at a conference during the first week of May. Thanks again to all our downloaders and everyone who takes the time to send us feedback and questions. There would be no podcast without you.

Note: We had several audio problems attempting to record this episode due to erratic network connectivity. Everything is cleaned up and organized nicely except for one brief audio dropout that could not be recovered. You’ll know it when you hear it.

LHS Episode #006

After putting this off some because of the holidays and other obligations, Episode #006 is now hot off the press. This is the second in our two-part series on PSK31. In the first part, we looked at sound cards, rig control interfaces and the basics of getting a PSK31 software package installed on your Linux operating system.

In part two, we take a much closer look at two popular programs for operating PSK31 mode on Linux: gmFSK and fldigi. On top of that, we respond to listener comments and questions, talk about updates to the web site, and explain how you can be involved in the recording of Linux in the HAM Shack by listening to the live feed and interacting with us in the chat room.

Next up in Episode #007: Install episode! We’ll guide you step by step through the entire process of installing Debian or Ubuntu Linux on a machine to use in your HAM shack. If you join us for the live feed, we’ll even be able to answer your questions in real time.

Stay tuned, and please, keep the feedback coming.
