LHS Show Notes #046


  • The eighth annual Ohio LinuxFest will be held on September 10-12, 2010 at the Greater Columbus Convention Center in downtown Columbus, Ohio. Linux in the Ham Shack will be there; will you?
  • Russ is in a bad mood, tonight. Send him lots of feedback!
  • Black Sparrow Media was intended to be similar to Hacker Public Radio, a clearing house for several podcasts, and Russ has ressurected it. Currently, we have LHS, Resonant Frequency, and Russ' latest venture, the QSK Netcast.
  • Another all feedback episode.


  • Paul, KE5WMA, sent a donation. Thanks, Paul!


  • We had several listeners comment about the possibility of releasing LHS only in OGG format:
    • Email from Frasier say that he votes for keeping the MP3 feed as he relies on his iPod to listen. We'll be keeping both formats for the foreseeable future. There is the RockBox OS for most iPod models, which would allow you to play OGG files, but that would replace the existing OS on the iPod and break iTunes.
    • David, KG4GIY and the ham radio editor for Linux Journal, comments on the web site that he also votes for the MP3 version, again because he subscribes with iTunes. However, in about a month, he'll be converting to Fedora and will no longer use iTunes.
    • Matt, KC8BEW, has a couple of thoughts about the MP3 vs OGG debate: if you're a Linux user, you should be able to convert to whatever format you want. However, MP3 is probably more convenient for most people. Our hosts note that xiph.org has components that make it possible to play OGG in Quicktime and iTunes, but once you take a file out of the feed, then it ends up in the iTunes music library, and not in the podcast category.
    • Charles, KJ4VEB, comments on the web site that he would be more than willing to try the OGG format. We agree that there are benefits to OGG, but there are too many listeners that rely on the MP3 feed to abandon it at this time.
  • Ross, WI0N, says he's writing a Windows TCP/IP client application that uses AGWPE (SV2AGW Packet Engine) winsock layer to get digitized packet data and satellite telemetry through a RigBlaster plug and play device, but would like a Linux solution. Does Fldigi have the lower level layer that works with the sound card to digitize and format KISS data, or does it sit on top of that layer like Ham Radio Deluxe does? Our hosts suggest reviewing the Fldigi documentation and source code and the AX.25 website.
  • Following up in a voicemail, Ross thinks the Linux soundmodem driver might provide the ASCII stream he's looking for from the /dev/soundmodem0 device. Russ agrees that it looks like the AX.25 kernel module does support getting the data stream from the soundmodem device. Richard suggests contacting Phil, KA9Q, as he's involved with this type of work.
  • WW (Bill), KB9TMP, replies to Russ' comments in episode 42 about Field Day sites not being handicapped accessible. The Hoosier Hills Ham Club in Bedford, IN does make an effort to make their activities wheelchair friendly. Thanks, Bill!
  • Paul, KE5WMA, wrote in via the live support link on the web site asking about a good Koch Morse Code trainer in Linux. There is a SourceForge project, that does both Farnsworth and Koch. There may be others. (Ed. note: Paul, you may find other CW programs via the Hamsoft Linux Software index.) Ross, in the chat room, also provides a link to the CWirc site that provides "an X-Chat plugin for sending and receiving raw Morse code over IRC". Thanks, Ross.
  • Rich, KD0BJT, from the Low SWR podcast, and Dan, KG4JCL, said they have had problems getting LHS episodes with gpodder. Firefox, too, failed to get the feed. Russ suggested deleting and re-adding the feed in gpodder, and Rich said that worked for him.
  • Randall, KC4WZE, writes a long email about episode 39: He thinks that for Linux to gain widespread acceptance, we need to create a new perception of Linux much like the difference between a PC and a Mac. Right now, most people identify PCs with Windows, so we need to create a new device name for computers running Linux, like "Tux". Most people understand the difference between a Mac and a PC, so the difference between a PC and a Tux would be similar, as long as all Tux applications can run on all Tux computers. Our hosts discuss this topic, and mention such companies as System76 and Penguin Computing, that already provide machines designed with Linux in mind and with Linux pre-installed.
  • Randall continues with a discussion of embedded Linux appliances. He suggests the possibility, for example, of the same media playing application running on your cell phone, portable video player, desktop computer, car radio, and television. Our hosts discuss the practicality of this concept.
  • Finally, Randall comments that a Linux "Tux" netbook might be the next "killer" device. Our hosts discuss this. There are already a variety of devices running Linux, such as the Android smart phone, the Archos 5 internet tablet, Archos 7 home tablet, TiVo DVR, Boxee Box media center, and Roku digital video player. (The TomTom line of GPS units also run embedded Linux. -Ed.)
  • Thanks for the thought-provoking email, Randall.
