LHS Show Notes #027

Posted on by Russ Woodman

Contributors:

  • Russ visited a Ham Radio Outlet in Virginia and bought a new Yaesu FT-7900R for his truck.
  • Richard bought a Kenwood TS-50, some wire and antennas at the Belton hamfest, but hasn't installed them yet.
  • John, EI7IG, says you don't need AX.25 support in the kernel to run XASTIR, since you're running the TNC in KISS mode. He also says that APRS is useful for emcomm events, disseminating local weather information, and passing short text messages.
  • Tim, KI6BGE, recommends Resonant Frequency, Linux in the Ham Shack, and SolderSmoke in his October 29 blog entry.

Announcements:

  • We received a donation from Paul during the last episode, and now Alex made a sizable donation. Thanks, Alex!

Contributors:

  • Kent, VE4KEH, writes in the forums that the Debian Testing updates have caused him some problems. Richard suggests not using the Testing distribution, while Russ disagrees.
  • Do any of the ham radio digital protocols support full TCP/IP? Can we load a web site via packet radio?
  • Commentsabout Episode #025:
    • Alex, OZ9AEC, says that he'd rather attend an Ubuntu launch party every six months, rather than a Windows party every six years. 🙂 He provided a link to an Ubuntu 9.10 Release Party Map.
    • Jim, N3JIM, defends APRS (Automatic PACKET reporting System), saying it's more than just vehicle tracking.
      www.aprs.org says it's "automatic packet reporting system"
      www.aprs.net says it's "automatic position reporting system"
      Our hosts discuss the apparent usefulness, or lack thereof, of APRS.
  • Richard rants about receiving spam, this time from Twitter.

Announcements:

  • Please donate to the fund to send Linux in the Ham Shack to the Dayton Hamvention in 2010!

Links and Notes:

  • Joe, NE3R, provides this audio segment about minicom, a Linux terminal application for connection to serial port devices. Check out Joe's blog.
  • Audio from Russ at Ohio Linux Fest:
    • Talking to Jim, KB3ORA.
    • Handing out DVDs of the first 22 episodes.

Contributors:

  • Paul, from TeenRadioJourney.com, mentions LHS on his blog.
  • Russ Wenner from The Techie Geek podcast joins us in the chat room.
  • Kent, VE4KEH, in a post in the forums, says he heard Russ on an episode of Hacker Public Radio, and wonders if an appearance on Linux Outlaws is next. He also asks about a Windows 7 launch party. Our hosts respond.
  • Kent also posts a comment in a thread about Acer dropping support if you install Linux on one of their computers. Kent asks which manufacturers are Linux friendly? He also wonders why Acer creates two partitions on their laptops.
  • threethirty from Linux Cranks sent congratulations about LHS getting a mention in an LXer.com article Ohio LinuxFest Report
  • Matt, KC8BEW, in a comment about Episode 22 asks if Chirp will support radios other than Icom D-Star.

Announcements:

Links and Notes:

  • Russ talks a bit about being at Ohio Linux Fest. He was in "podcasters row" in the exhibit hall, along with the Northeast Ohio Open Source Society, The Linux Link Tech Show, and the Security Justice podcast. Russ shares some interviews and audio he recorded:
    • Interview with Matt, KC8BEW.
    • Russ plans on taking Linux in the Ham Shack to Dayton Hamvention, 2010.
    • Jim, KB3ORA, stops by the booth.
  • Questions in the chat room:
    • Russ Wenner from the Techie Geek Podcast, asks: is ham radio an expensive hobby? Richard opines.
    • HamTests.net is a good resource. The European site is HamTests.co.uk.
    • Do you need to learn Morse code? Nope, but it's even more popular now.
    • Do you need a high antenna? Not necessarily. Russ discusses. The ARRL has several good books on antennas.
    • Paul Shirey asks if shared folders on different machines can be combined. Possible, but difficult.
  • Richard talks about APRS and XASTIR.
    • One of the requirements for using APRS under Linux is that you must have the AX.25 packet radio protocol support in the kernel.
    • To determine if your kernal has AX.25 support, enter this command in a terminal: 
      grep ax25 /proc/kallsyms

      If you get a result something like this:

      c0510ddc r trans_net_ax25_table
c05127a0 r trans_net_ax25_param_table

      then AX.25 support is built into the kernel. If you receive nothing, then you'll need to recompile the kernel with AX.25 support. (Most of the current versions of Ubuntu and Linux Mint have AX.25 support.)
      For more information, see the HowTo:AX.25 article on the XASTIR wiki.

    • Richard describes configuring XASTIR.
    • Bottom line: it's not all that hard to set up. Read the wiki. There are how-to articles for many different operating systems.
  • From the chatroom, someone asks about the throughput of the various data modes in amateur radio.

Music:

  • "Like This" by STEEP from the album "STEEP"
  • "Lost" by Trainlight from the album "Now You're Alone with Ghosts"

LHS Show Notes #024

Posted on by Russ Woodman

Richard and Russ are the Penn and Teller of Amateur Radio podcasting.

Contributors:

  • Doug, N6LMX, recently acquired an old Dell Inspiron 3500 notebook and decided to try Linux Mint on it. For some reason, probably processor and memory, it stalled before it got started. Same with Ubuntu 9.04. However, Xubuntu 9.04 works like a charm.
  • Joe, NE3R, sent an audio message about minicom. Thanks, Joe. Look for it in a future show.
  • Google alert about a LHS mention in John's Blog.
  • Paul in the chatroom asks about connecting a Linux machine to a shared Windows printer. Russ suggests browsing to https://localhost:631 to bring up the CUPS administration page and configuring the printer there.

Announcements:

  • New streaming audio on the web site. New URL: https://stream.lhsinfo.org:8008, or go to https://lhsinfo.org and look for the links on the right side of the page.
  • Look for Richard at the Belton HamEXPO on October 3rd. in Belton, TX. Russ will be at Ohio Linux Fest on September 25-27 in Columbus, OH.
  • Welcome Bill, KA9WKA, as the newest member of the Black Sparrow Media production team. Bill will be compiling the show notes for Resonant Frequency. (And, now, LHS too. Email comments, corrections, suggestions to ka9wka at blacksparrowmedia dot com. -Ed.)

Interview:

Topic:

  • Richard discusses programming radios using Linux
    • Richard tries programming his Vertex VX-150 using Wine under Linux. The programming software installed fine, but when he tried downloading the data from the radio to the computer, he received errors, probably due to a mismatch in the serial port speed. Next, he tried programming his Icom IC-91AD. The software installed and recognized his serial port, COM1, and he was able to program the radio.
    • Tim, KI6BGE, in the chatroom, says the IC2200H D-Star program works the same way.
    • KB3GTN in the chatroom says he's had good luck programming his Kenwood TS480 within Linux, using his own program.
    • Tim, KI6BGE, says the Icom ID800 and IC2200H use the same programming cable, but different software.
  • A Ustreamer asks which Linux distributions we're using. The summary is Linux Mint, Ubuntu, Xubuntu, Kubuntu, SpearMint, CentOS, OpenSUSE, and Debian.

Music:

  • "Terra Firma" by Garrett Wall from the album "Sky Pointing"
  • "All of the Above" by Garrett Wall from the album "Sky Pointing"

LHS Show Notes #023

Posted on by Russ Woodman

Contributors:

  • Jeff has switched to Linux Mint. He asks about iPod syncing programs. He has tried Banshee and Amarok, and is not impressed. He'd like to use iTunes, perhaps under Wine. Russ suggests trying Songbird, if it supports your device. Check their wiki page to see if your device is supported.
  • Tweet from M0GLG regarding Echolink under Wine. He says it works with no real issues other than configuring the sound devices. He hasn't managed to get it to work with USB devices, yet.
  • Comment on the website about episode 20 from Matt, KC8BEW. He is looking forward to seeing Russ at Ohio Linux Fest.
  • Look for Richard at the upcoming Belton, TX hamfest.
  • LHS was mentioned on Jonathan Hardy's blog KIX-online in the August 30 post.
  • John, EI7IG, posted a message in the forums providing a link to information on compiling XASTIR from source, and mentions the Linux RMS Gateway software for accessing Winlink 2000 networks. He also says the Windows Winlink 2000 client, Airmail, works fine under Wine.
  • Clay, K6AEP, writes that he has an Eee PC 1000he and 702, and says you can use applications on the smaller screens. In eeebuntu 3.0, hold down the Alt key and you can move the screen around to see the rest of it. Crossover 8 has allowed him to avoid using Windows except for a couple of programs, such as Echolink. It seems to install fine, but mic audio doesn't work. He's tried SUSE 10 and 11, CentOS 4 and 5, Slackware 12.2, Ubuntu, Mint, Extreme Ubuntu, and Debian, and a variety of computers. He likes Ultimate Edition Linux 2.3, based on Ubuntu 9.04, even better than Mint 7.
  • Gary, M0TXD, comments that he has just installed Ubuntu on his hamshack computer with four serial ports, but can't get them to open. Russ suggests that it's a permissions problem on the devices.

Announcements:

  • Russ was invited by Klaatu of Linux Cranks to join their fourth roundtable discussion. The topic is the most common Linux applications on the desktop. Look for it on Hacker Public Radio (.mp3 file).
  • Linux in the Ham Shack has become an official sponsor of Linux Mint.
  • lhsinfo.org now has streaming audio links.
  • Check out Ohio Linux Fest. Russ will be there. Will you?
  • Question from the chatroom: How do I change from Ubuntu to Linux Mint? 1) Download the .iso and install it, but that will likely overwrite everything on your machine. 2) Get the sources.list file from a Mint installation (if you are on Ubuntu 9.04 already and want Mint 7) and update the repositories, then do an apt-get dist-upgrade. Russ tried that, and it worked pretty well, but there were a couple of package conflicts that had to be handled manually. The safest and easiest is to just install from the .iso, especially if you already have your /home directories in a separate partition. No matter how you do it, you should backup your system first.
