• The 2013 Dayton Hamvention will be May 17-19, 2013. Russ is hoping to have the LHS booth again, but we need your help. Please donate if you can. Every little bit helps.
• Kevin O’Brien, Publicity Director for the Ohio LinuxFest, tells us that they have set up a brief survey to gather ideas for the 2013 Ohio LinuxFest. Visit http://ohiolinux.org/ to find the survey.
• Northeast Linux Fest will be March 16th and 17th, 2013, at Harvard University in Cambridge, Massachusetts.

Topics:

• Russ’ Raspberry Pi adventures continue. His Echolink node 54711 is now up and running on a Raspbian-based Raspberry Pi with svxlink and Qtel. Russ had to insert “dwc_otg.fiq_fix_enable=0″ into the /boot/cmdline.txt file in order to fix a problem with the onboard Ethernet card locking up. Since then, all has been well.
• Amateur Radio Pi is a forum with the tagline: The interactions between amateur radio and the Raspberry Pi.
• The Society for the Preservation of Amateur Radio (SPAR) will conduct a Winter Field Day, beginning 1700Z on January 26, 2013 and ending at 1700Z January 27th.
• HamSphere is a software Amateur Radio simulator that allows licensed radio amateurs and unlicensed enthusiasts to communicate with one another using a virtual transciever over the Internet. It was designed by Kelly Lindman, a radio amateur with callsign 5B4AIT. The software runs under Windows, Mac or Linux. There’s also a Wikipedia page for more information.
• RepeaterBook is an Android application for locating amateur radio repeaters. There are lots of options, including repeater types and modes (D-Star, etc). It also supports the BlueCAT Yaesu FT-857/FT-817 interface that allows you to tap a repeater entry in RepeaterBook on the phone and it will set your radio frequency.

Feedback:

• Comment via the Web site from Leif, KC8RWR, with another attempt at explaining hard and soft links, which we were discussing in episode 95. Thanks, Leif.
• Leif also commented about difficulties hearing a mobile radio without a speaker in the head unit.
• A very strange voice mail from the Radio Gangsta, aka Rich, KD0RG, from the LowSWR podcast.
• E-mail from gasgasmike, asks if it would be possible to use short wave radio to provide wireless Internet service. Our hosts discuss the practical difficulties with such a scheme. (Note: the use of the amateur portions of the radio spectrum for commercial purposes is expressly prohibited by the FCC.)
• Jeff, KC2QZO, sends his appreciation of our discussion of Codec2 in episode 85.
• Russ mentions that there is another low-bitrate codec is being developed: The Opus Interactive Audio Codec.

Sometimes you feel like a nut. Sometimes you don’t. Luckily, Richard’s miraculous recovery from the Creeping Death outweighed Russ’s totally miserable Ides of January, resulting in a listenable episode with a bunch of content–mostly thanks to elcaset, a listener of the show, via IRC. There’s also a bit about svxlink using a Raspberry Pi (yes, it is possible and completely functional) and lots of information about upcoming events. We’d like to thank everyone you who submitted feedback, including The Radio Gangsta, who we also hope will get some much-needed psychological attention soon.

If you think about it, make sure to download the Black Sparrow Media app for your iPhone, iPad or Android device. And please tell your friends about the show. Have them sign up for the mailing list, episodes via RSS, the Google+ community and all the other ways they can keep up with what’s going on in LHS Land.

Introduction:

• Welcome to another episode of Linux in the Hamshackedness, where the Chocolate Shake Fairy visits Richard.

Announcements:

• LHS now accepts micropayment donations via Flattr. It’s been successful for the Linux Outlaws guys, so we’re giving it a try here.
• We now have a countdown timer on the Web site that shows the time remaining until the next live recording. Of course, now that we’re recording on Wednesdays, we’ve decided to move back to Tuesdays. That will happen in January. Keep an eye on the web site for the dates. (Tuesday, January 8, 2013, as of this moment.)
• We also have a Google Community for Linux in the Ham Shack. It’s a great method for leaving feedback, show suggestions, questions, hate mail or anything else.
• The Dayton Hamvention 2013 will be coming up soon, so we’ve added the donation thermometer to the website. Please make a donation and help send LHS to Dayton again in 2013.
• Sign up for the LHS mailing list, too.
• Gnorman has a bio on the LHS About Us page.

Topics:

• Raspberry Pi in the Ham Shack
  • Russ has been working on getting an Echolink node running on his Raspberry Pi.
  • He’s chosen Raspbian as the operating system, which is based on Debian Wheezy.
  • Installation consists of downloading the iso, using dd to copy it to a secure digital card (SD flash memory card), booting the Raspberry Pi with the SD card, and following the prompts to install.
  • VK2MEV has posted instructions for configuring a Raspberry Pi as an Echolink node.
  • So far, Russ has Raspbian installed, as well as svxlink and qtel, but has not yet connected it to the usb sound card or attached it to his Rascal GLX interface to control the radio. Another option would be to use the Pi’s GPIO bus to control the radio instead of a digital mode interface.
  • VK2MEV also has a page describing WSPR on a Raspberry Pi. (Another page is VK2MEV’s blog on WSPRnet.)
  • Ted, WA0EIR, says he thinks some folks have his PSK31LX program running on a Raspberry Pi.
  • Russ mentions that there is a Slackware build for the Raspberry Pi.

Feedback:

• Cory, KD0QEA, asks if there are any “hangout” radio frequencies for LHS hosts and listeners. Well, Cory, there are none due to lack of time for the hosts to get on the radio. However, perhaps our listeners would like to establish an LHS net. Email your suggestions for bands, frequencies and times and we’ll announce them on the podcast. When Russ gets his Echolink node/Raspberry Pi running, he’ll be there more often. The node number will be 54711 (LHS11 on the telephone pad).
• Doug, N6LMX, left a voice mail about the Raspberry Pi. He has one and wonders which ham radio apps can be used on the Pi. He’s also using Raspbian as the operating system. Doug will be attempting to create a media center with his, as well as ham radio applications. Russ suggests running the Pi headless and using ssh from a smartphone or tablet to access it. That would avoid having to carry a monitor and keyboard around with the Pi. It’s likely that most of the popular Linux ham applications, such as fldigi, would work fine with the Pi, though you may need to compile them yourself. As for the media server idea, the Pi may not be quite powerful enough. Raspbmc is based on XBMC, and might be the best option. Ted, WA0EIR, has several Linux ham radio applications that should work quite well on the Pi. Richard also wonders if there are folks running APRS on the Pi, and there’s at least one. Thanks for the voice mail, Doug. We appreciate it.
• Dave, M0DCM, has been catching up on the show, and responds to episodes 95 and 96. He uses 75-ohm coax as a feedline with a 1:1 balun to horizontal and vertical dipoles, and is able to bypass his tuner on 21 and 24MHz. He goes on to describe his Linux and radio activities. Thanks, Dave.
• Thanks to everyone who sent happy birthday messages to Russ.
• Gorkon, aka Joel, says there may have been a problem with the ogg version of episode 96. Russ will take care of it if he finds the problem.
• Mike, from Sugarland, TX, has been trying to use N3FJP’s Amateur Contact Log (ACLog) program for logging, presumably under WINE, but it crashes and he wonders if anyone else has had any experience with this. If any of our listeners have tried ACLog under Linux, let us know, or respond on the Google+ LHS community. Russ suggests forcing WINE into 16-bit compatibility mode.

Welcome once again to the Wonderful World of Linux in the Ham Shack. As indicated in the title, this episode is full of Sheer Hamshackedness. If you’re unsure what that is, we encourage you to pour yourself a nice glass of dark beer or a 100-proof spirit of your choice, put on your headphones and immerse yourself in the pure hedonism that is LHS. And if you believe any of that, we have a large vehicular conveyance over the East River in New York City up for sale as well. Anyway, we talk a little bit about Raspberry Pi computing, APRS, WSPR, Echolink, svxlink, Qtel and a bunch of other stuff in this episode. Hope you enjoy, as always.
