LHS Show Notes #048

Posted on by Russ Woodman

Feedback:

  • John, KF6EFG, commenting on the OGG vs. MP3 debate in episode 43, agrees that MP3 is the preferred file format because that it is supported by most media players. He realizes that OGG is superior, but until vendors like Apple support it, it will not gain on MP3. Richard thinks it's because Apple cannot add DRM to OGG files. Russ thinks that if Apple did use OGG, they'd sell more iPods. In any case, LHS will not drop the MP3 feed.
  • Lief, KC8RWR, writes a detailed reply to comments Randall, KC4WZE, made in episode 44 about running the same applications on cell phones and computers. There is a way to hack an Android phone to run Debian, or run Android on your desktop. Check out the TuxPhone project. Richard and Russ discuss.
  • John, EI7IG, was interested in the discussion of Logbook of The World in episode 43. He pointed us to www.rickmurphy.net/lotw for a newer version of TrustedQSL created by Rick Murphy, including a Linux version. Russ tried it and it works. (Ed. note: The softare is no longer available on Rick Murphy's site. Evidently, it has been obsoleted by Trusted QSL 1.13 from ARRL. Linux source packages to compile the library and program are available from the LoTW Instructions page.)
  • David, M0DCM, writes that he was recently at the Telford Hamfest and found that Linux was represented there, thanks to the Shropshire Linux User's Group and MAXPAK, the Midlands AX25 Packet Radio User Group. They had demonstrations of Linux machines running Fldigi and WSPR, showing just how far Linux has come. They gave away a bunch of Ubuntu CDs, some to LHS listeners! (A couple UK podcasts for ham radio and Linux are the ICQ Podcast and the Ubuntu UK Podcast.)
  • Russ was at the Joplin ARC Hamfest and had the LHS booth there. He gave away 20 Ubuntu 10.04 CDs. WebSDR was a big hit, too.

LHS Episode #048: Better Late Than Never

Posted on by Russ Woodman

Linux in the Ham Shack took a bit of an unintended hiatus over the last month. We're in the process of trying to catch back up to where we're supposed to be. The current episode recording schedule has been posted and is accurate. We're going to do a couple of broadcasts two weeks in a row and then the next three releases will be coming out in rapid succession so we're back on track.

After the Dayton Hamvention, Southeast Linux Fest, Joplin ARC Hamfest and Ohio Linux Fest, things have slowed down a bit on the event front, but we're just starting up again when it comes to the show. So please stay tuned, tell your friends about us, and make sure to pick up a shirt or a ball cap. These are high quality items, and the only way you can get them is online or when we're at an event close to you. Also, check out the new BADGER WEAR! You can find a link to all of our merchandise at the top of this Web site. Have a good week, everyone, and thanks for listening!

LHS Show Notes #045

Posted on by Russ Woodman

Announcements:

  • The drawing for the Southeast Linuxfest prizes will be next episode.
  • Problems with GoDaddy prevented the download of the last episode for a time. It seems to be fixed now, but we may be moving to another hosting company.
  • Visit https://wiki.edubuntu.org/UbuntuHamsNets for a list and schedule of ham radio nets for Ubuntu users. Everyone is welcome!
  • Some listeners reported problems playing the OGG file of the show with VLC. All episodes through #35 worked, but #36 and later did not play in VLC.  The problem was that the cover art image was too large for the OGG file metadata specification (64KB), which caused VLC to choke. The Totem player was not respecting the specification and would play the file anyway. The cover art image was reduced to less than 64KB, and the OGG version of episodes 36 onward have been repaired and should now play properly in VLC.
  • Would you object if LHS was only available in OGG format? Let us know!
  • LHS has an online assistance feature! There's a Live Support button on the right-hand side of the LHS web page that will initiate an interactive chat session with the hosts of the show, if they're online.
  • The "Thesis" WordPress theme has caused controversy as it's not GPL, but because WordPress is open source, and the theme is a derivative of the WordPress program, then Thesis should be GPL, too. See the articles on Geckotribe and Mixergy for more on this topic.

Donations:

  • We received donations from Jonas and Ross, both in the chat room tonight. Thank you!

Feature:

  • Richard and Russ discuss Logbook of the World, TQSL, and support for Linux.
  • Dave, KG4GIY, sent along some information about TQSL support for Linux being dropped by ARRL, which would cause problems for applications such as CQRLOG.
  • There is a SourceForge project that provides software to build the TQSL libraries under Linux. Russ came up with the following procedure to build the software under Ubuntu, or you could just try executing:
sudo apt-get install trustedqsl

  • Building TrustedQSL under Ubuntu

    1. Install the required libraries: 
      sudo apt-get install libssl-dev libexpat1-dev zlib1g-dev g++ build-essential
    2. Download and extract the tqsllib and TrustedQSL software from SourceForge
    3. A minor change is required in the openssl_cert.cpp file from the tqsllib package to add an if statement allowing it build on recent versions of Linux with openssl 0.9.8. In patch format, the code for this update is at the bottom of this section.
    4. Execute the following commands to build the library: 
              # ./configure
        # make
        # make install
  • Again, if you're using Debian, Ubuntu, Linux Mint, or similar Debian-based Linux, you can simply type 
    sudo apt-get install trustedqsl

    and not bother building the library yourself. In the end, your Accessories menu will contain tqslcert, used to get the certificate from ARRL, and TrustedQSL, used to encrypt your ADIF log data and submit it to LoTW.

  • Applications like CQRLOG will then work with LoTW.
  • Russ describes the process for obtaining a certificate from the ARRL.
  • The ARRL also seems to contradict itself in its support of Linux. On the Resources page, under the entry for CQRLOG for Linux, it says "Please note that ARRL does not support Trusted QSL for Linux." However, the FAQ page says "At present one needs to use a computer with Windows or Linux operating systems to use TQSL and TQSL Cert."
  • Richard suggests we all should send a letter to the ARRL demanding Linux support in LoTW.
  • Paul, KE5WMA, in the chat room points us to the Ubuntu Linux for Hams article posted July 26, 2010 at ARRL.

Feedback:

  • Scott, N9LJX commented on the web site about his desire for a decent logging program for Linux that interfaces with LoTW. CQLog is close, he says, but lacks in the award tracking area. So, unless we can offer an alternative, he's staying with Windows and the DXLab suite. Russ and Richard discuss CQLog (a Windows program) and CQRLOG (a Linux program). Perhaps, at the moment, Windows and the DXLab suite is the best solution for you, or you might try running Windows in a VirtualBox session under Linux.
  • Jason, KB9LAF, asks if we know of any Linux software that will run his Icom ICPCR-1000 receiver. Russ found this article in the Ubuntu forums. (Ed. note: Here are a couple possibilities: A Python application that will run under Windows or Linux, and IcomLib.)
    He also mentions Pendrive Linux as a means of running Linux from a USB drive.
    Thanks, Jason. We talked about that in Episode 19.
  • Kallie asks if the New Logo contest would reopen and asks why it was cancelled. There were no entries, so Russ paid for a new logo. But feel free to submit your art, if you wish.
  • Tim, KI6BGE, writes about his trouble with PCMCIA wired and wireless network cards under Linux Mint 9 LXDE on his IBM T21 laptop. They used to work with SUSE. Any suggestions? Russ and Richard discuss. They suggest running lsmod under Ubuntu to determine which drivers are loaded when the network cards work, then check what lsmod shows under Linux Mint, determine what's missing, and modprobe the missing drivers.

LHS Episode #045: Logbook of the World

Posted on by Russ Woodman

Episode #043 of Linux in the Ham Shack almost didn't exist. In the process of trying to edit the audio for the program, I managed to delete everything that I had recorded. By some miracle of coincidence, I actually remembered to record the entire episode at Ustream.TV. I almost never remember to do that but it happened this time. The audio was recovered from the live video stream and I put it back together. There are a couple of minor flaws and the quality might not be as good as normal but at least it exists. Since the edited version came out to over 100 minutes, I'd sure have hated to try and record this all over again. And that's why this episode almost didn't exist: Because if the audio had truly gone away, I would have thrown up my hands and said forget it. We'll try again in two weeks.

But since we got lucky, you can now listen to us talk about our newest features and endeavors, our problems with the ARRL, the status of Logbook of the World, listener feedback, live chat room discussion, installing Linux Mint on an ancient laptop, ham radio software for [that other OS] and much, much more. And hey: Go buy a shirt. Please?
