LHS Show Notes #056

Posted on by Russ Woodman

Introduction:

Announcements:

  • Hello to the new folks in the chat room.
  • The Mintcast podcast is either going to stop or will have new hosts after the next episode. If you're interested in hosting a podcast, contact the folks over there.
  • Please spread the word about MAGNetcon, the Mid-America GNU/Linux Networkers Conference, to be held May 6-7, 2011 at the St. Louis Union Station Marriott. If you know anyone that might be a sponsor, exhibitor, or speaker, please let us know. Application forms are available on the web site.
  • Check out the new website for Resonant Frequency.
  • Also mentioned, the Going Linux podcast and Computer America, "America's longest-running nationally syndicated radio talk show about computers."

Feedback:

  • Richard, KR4EY, writes about CW... wait, we did this one in Episode 52.
  • John, KC8DAX, weighs in on the Windows vs. Linux debate: there are hams that will buy a wire antenna and there are others that will build one. He thinks it's the same thing with operating systems. Would you want a radio you couldn't open? Our hosts discuss.
  • We received a donation from Charles to help send Linux in the Ham Shack to the 2011 Dayton Hamvention. Thank you, Charles!
  • Joe, K1RBY, recently discovered the podcast and is catching up, but is having a problem using gpodder to retrieve episodes. Yes, Joe, there is a bug in one of the WordPress plugins on the web site that contributed to the problem (see lhspodcast.info for a description of the problem.) It has been corrected.
  • John, K7JM, also had the problem with gpodder and sends his appreciation for the fix.
  • Richard, KJ4VGV, tells us that he is a new amateur radio operator since May and has published an article: Antenna Restrictions: Are They a Catastrophe Waiting to Happen? Good job, Richard!
  • James, N2ENN, comments about our episode 52 when we discussed Unity, and offers his thoughts on Wayland, Debian and Ubuntu. Our hosts discuss, and digress to a discussion of browsers, plugins, drivers, ALSA and PulseAudio on Debian vs. LinuxMint Debian Edition. They also commment on Bill Meara's (of SolderSmoke fame) efforts to get WSPR running under WINE in Ubuntu.
  • Paul, KE5WMA, writes "PIC micro controllers are getting more popular in HAM projects. Any suggestions on programming software and boards?" Well, Paul, Linux does still support serial ports, but this may be a good topic for another show. You might find something useful in the many hits returned by a Google search on "Linux PIC programmer".
  • B.B., KC5PIY, asks for help with getting Windows programs for programming radios, such as the Icom IC-2820H and IC-706 MkIIg, running under Linux. He'd also like an APRS client. Richard recommends UIView as an APRS client for Windows, and Xastir for Linux. Russ suggests that most of the radio programming applications will run under WINE in Linux. Also, check out CHIRP, free Linux software for programming a variety of D-STAR radios. You may also want to explore the D-RATS mailing list. It's not likely you'll be able to dual-boot Windows and Linux on that netbook, but you can install Ubuntu Linux using WUBI, which would allow you to run Linux within Windows, or install Linux to a USB flash drive using Pen Drive Linux.
  • Craig, KB5UEJ, writes about learning IPv6: "I went through the Hurricane Electric certification program and really learned lots about IPv6. I'm now running IPv6 on my home using HEs IPv6 tunnelbroker service. It's no longer the big bad scary thing that it used to be." Russ also talked about IPv6 on episode 6 of his QSK podcast.
  • Matt shares his thoughts about building "simple" projects from junk box parts and the similarity to running Linux.

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?

LHS Show Notes #033

Posted on by Russ Woodman

All of us at Black Sparrow Media wish to express our sincere condolences to Richard on the passing of his mother. Our thoughts and prayers go out to Richard and his family. He won't be joining us this time, so we'll carry on with a round table episode.

Contributors:

  • Ted WA0EIR, in snowy Iowa, Andy aka Integgroll on IRC, and Bill KA9WKA join us for a round table discussion.
  • Jay writes in about the Linux Journal episode (#029) and the analysis of the Amazon Kindle and DRM issues. Our panel talks about the Kindle , e-readers in general, and DRM issues. Russ mentions how Amazon retracted a couple of George Orwell titles.
  • Google alert tells us that Linux in the Ham Shack and other amateur radio podcasts are being played over a local repeater by Tony VK7AX for the enjoyment of listeners in SE Australia and Tasmania. Good on ya', mate!
  • LHS was mentioned on Joe's (WN2SYZ) blog. Thanks, Joe!
  • Dave, KG4GIY, posted another mention of LHS at Linux Journal when we talked about software-defined radios (SDR) in Episode 26. Thanks, Dave! Check out the Linux Journal amateur radio content.
  • Chris, Twitter ID WOKNSS, tweeted about catching up on back episodes of LHS. Thanks, Chris!
  • LHS was mentioned at the Low SWR podcast website. Low SWR is an amateur radio podcast produced by Rich KD0BJT and Brady KD0BJS. They're up to eight episodes already! Good job, guys!
  • The Axis wrote to us, Mint Cast, and The Linux Link Tech Show to thank us all for content about the Linux program screen. We're glad you enjoyed it. A possible application might be operating digital modes remotely. (Bonus Show Notes Content: The February 2010 issue of QST has a Short Takes article about the Glentek Radio-to-Ethernet Controller. Glentek has a variety of products to facilitate remote operation of an amateur radio station. -Ed.)

Announcements:

  • Texas Linux Fest is April 10, 2010 at the Monarch Events Center in Austin, TX. You might find Richard or Russ there, so say Hi!
  • Donations: We've achieved our goal! Walter, KV6M, made a second donation (thanks, Walter!), and the remainder was supplied by Beth Lynn Eicher of the Ohio Linux Fest. Thank-you, Beth Lynn! Look for the Linux in the Ham Shack booth at Dayton Hamvention 2010. (Note: the podcast incorrectly identifies Walter as WN3LIF, another Walter that also contributed.  We apologize for the confusion. -Ed.)

Links and Notes:

  • From the chat room, Ronnie K4RJJ, asks what PDAs would work with sound card digital modes. There's i-PSK31 that will allow you to use PSK31 with your iPhone and radio. It's also available via the iTunes store. (Note: I mistakenly said the price was $1.99. The actual price is $5.99. Sorry. -Ed.) There is also some documentation on how to wire the headphone plug for the iPhone for connection to your radio.
  • Ted rants about the use of macros in digital conversations, and the panel discusses.
  • The panel discusses the appropriate power levels for digital modes. Lower power, say less than 35W, is usually enough. There are devices, such as the PSKMeter, that attaches to your transmitter output and, along with software, will display your signal so you can avoid splatter. PSKScope is another program for the PSKMeter that provides additional functionality, such as automatic audio drive level control, but only in the Windows version. A Linux version of PSKScope is available, but does not have the automatic drive level control. The other device discussed is the IMD Meter, which is a standalone device that displays your IMD while you are transmitting. No computer or software is necessary.
  • Next, the panel talks about operating via VHF/UHF satellites. (There's a good introductory article on the AMSAT web site. Randy, K7AGE, has produced several YouTube videos of various amateur radio activities, including this one where he operates AO-51. Another video from the 2007 Dayton Hamvention shows a similar system.
  • Bill introduces the microHAM USB Interface III. (That's the Americas website. There is also a site for Europe. The panel discusses the merits of the device.
  • We then move to a discussion of Linux Mint 8 "Helena".
  • Bill rants about Yaesu microphones on their VHF/UHF radios.
  • Russ talks about some cloud computing applications: Ubuntu One and Dropbox. The panel discusses the relative risks and advantages of using such services.

Music:

  • "Don't Go" by TenPenny Joke from the album "Ambush on All Sides".
  • "Mirror of Humans" by Amity in Fame from the album "Dinner for One".
