And we are back. In this installment, Richard tells us all about his renewed interest in emergency communications and his dealings with ARES in the Texas county where he now lives. On the Linux side of things, Russ talks about some security issues: the hacking of kernel.org, emacs violates the GPL and how to get cheap certificates for your Web sites. Throw in a dash of humor, some general screwing around and you have the formula for pretty much every episode of Linux in the Ham Shack. Thanks for sticking it out with us, everyone. We love each and every one of you.
Lord Drachenblut reminds us of the upcoming Indiana LinuxFest in Indianapolis, Indiana. If you'd like to register, use the promotional code LHSPODCAST50 (all capital letters) and you'll get a $15.00 discount on the ticket.
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.)
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.

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.
