Episode 50: A milestone!

Announcements:

• Russ talks about his California trip: attending the Large Installation Systems Administration conference (LISA).
• The 50th episode is a milestone – Richard explains why. See also The Internet Archive.
• Lord Drachenblut reminds us of the upcoming Indiana LinuxFest in Indianapolis, Indiana. If you’d like to register, use the promotional code LHSPODCAST50 (all capital letters) and you’ll get a $15.00 discount on the ticket.
• Music in this episode is from 20lb Sounds, fronted by Dan Lynch of Linux Outlaws fame.

Topics:

• Scott, AD7MI, posted an article on his blog about moving to an all-Linux ham shack. Richard and Russ discuss the article, including Shackbox Linux, Ham Radio Deluxe, CQRLog, and more. Ultimately, Fldigi and CQRLog resulted in “100% Linux Nirvana”.
• Scott also asks what we think would be the ideal Linux-based ham shack. Russ describes his shack, which he thinks IS ideal. Our hosts then discuss various soundcard interfaces:
  • RigBlaster
  • MicroHAM
  • Rascal
• Most sound cards work fine, and Russ recommends the SoundBlaster series over all, but suggests staying away from the SoundBlaster Audigy SE (model CA0106) sound cards as they don’t seem to work well (or at all) under Linux.
• Richard likes his Yaesu FT-897D. Most modern rigs allow a fixed-audio level connection to the computer sound card, as well as computer rig control. Russ has the Kenwood TS-570D, and it, too, is well-supported in the Linux ham libraries.
• Russ and Richard discuss the fact that most hams don’t log VHF/UHF contacts, other than in contests or toward an award.
• The FCC, created by the Communications Act of 1934, included the requirement to maintain a log book in the rules. Sometime between 1983 and 1986, this requirement was dropped as the FCC determined that the information was of little use to them. (If someone can point us to a reference that identifies when the exact rule change occurred, please let us know. I was unable to find the specific change online. -Ed.)

Feedback:

• Leif, KC8RWR, writes that Internet over EME (earth-moon-earth) isn’t likely to work due to the high latency involved. (This may be in reference to a comment in Episode 48.) NASA and DARPA are involved in a Deep-Space Internet project.
• Leif also asks “Isn’t Morse code dead?” and wasn’t it replaced by “Gerke Code”? Our hosts discuss.
• Craig, KB5UEJ, writes that he thinks Russ’ audio is louder and muddier than Richard’s in episodes 46 and 47. Russ agrees that the audio on a few of the recent episodes did suffer, but should be much improved now.
• Grant, KC9SJQ, comments that he doesn’t see a link to Russ’ screencast about SSL anywhere. Yes, it somehow disappeared, but Russ is working on it. He’ll either find the file or redo it.
• William, KB9TMP, sends his comments about Episode 48 where we discuss KE9V’s article that questioned the relevance of amateur radio.
• Craig, KB5UEJ, commenting about WSPR, says that you can run less than 5W on an FT-897 by reducing the audio drive from the computer to the radio. Richard points out that the reduction is often not uniform across the audio freqeuncies used, so some intelligibility may be lost. He had that problem with packet, but he’ll try it with WSPR.
• Matt wants to know the artist and title of a song in Episode 48. The song was “Endline (Choose Nothing)” by I Am Not Lefthanded from the album “Yes Means No”. Check out the show notes for Episode 48 for a link to the song.

Hello, podcast listeners! It has been an extra week that you've had to wait for our landmark episode 50 to be released. I (Russ)  had planned to do an episode from his hotel room in San Jose. Unfortunately, the network there was so bad it was impossible to record so everything was pushed back.

In this episode, we talk about life, love and amateur radio. OK, not really. But we touch on a number of interesting topics including the necessity of logging in amateur radio, theoretical nonsense like Internet via Moonbounce and, thanks to a couple of missives from AD7MI, we wax philosophical on our ideal ham shacks--computers running Linux included of course.

Thank you for being a listener of our show. If you're new: Welcome! Please tell everyone you know where they can find us. And keep fighting the good fight.

Due to extenuating circumstances, we will have to move the recording of Episode #050 to November 16th at 8:15pm CST. We hope to see everyone then.

Topics:

Ubuntu 10.10 – Maverick Meerkat

Russ upgraded from 10.04 to 10.10, which isn’t particularly easy. as 10.04 is the long-term-support (LTS) version, but 10.10 isn’t.

There is a command line command to upgrade:

do-release-upgrade

which will work, but you must first make a change in the Ubuntu software center. Click Edit -> Software Sources -> Updates tab. At the bottom of the Updates tab, there are three options for the release upgrade: Never, Long-term Support Only, and Normal Releases. You must select “Normal Releases”. Russ then issued the do-release-upgrade command. Once the downloads were complete, the upgrade just took about 45 minutes. A reboot is necessary due to the newer kernel.

The desktop background is a bit different, but otherwise it looks and runs much the same as 10.04. Russ had some performance issues with 10.04 on some of his machines. He thinks 10.10 runs much better.

Summary of changes

• GNOME updated to current 2.32 version.
• Gnome desktop manager (gdm) version 3. Russ thinks it looks more like OS-X.
• Evolution updated to version 2.30. Russ thinks they should drop Evolution entirely. There would be room for GIMP if Evolution were deleted.
• Shotwell replaces F-Spot as the default photo manager. F-Spot replaced GIMP in a previous release due to space issues, and now Shotwell replaces that. Isn’t this kind of silly?
• Gwibber updated to use Twitter’s new authentication scheme.

Kubuntu changes:

• More updates to KDE.
• Updates to Qt, and KDE (4.5.1).
• Switched to PulseAudio. Russ says: BOOOOO!, because he’s unhappy with all audio systems on Linux.

Ubuntu Server changes:

• Eucalyptus updated for cloud computing environments.

Kernel update:

• 2.6.35-22.33 Based on 2.6.35.4 upstream stable kernel.
• Support for i586 and older processors, and i686 processors without the conditional move opcode (CMOV), has been dropped. Bad news for older machines.

WSPR was highlighted in the November, 2010 issue of QST.

• What is WSPR? From the WSPR Users Guide:WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter.” The WSPR software is designed for probing potential radio propagation paths using low-power beacon-like transmissions. WSPR signals convey a callsign, Maidenhead grid locator, and power level using a compressed data format with strong forward error correction and narrow-band 4-FSK modulation. The protocol is effective at signal-to-noise ratios as low as –28 dB in a 2500 Hz bandwidth. Receiving stations with internet access may automatically upload reception reports to a central database. The WSPRnet web site http://wsprnet.org/drupal/ provides a simple user interface for querying the database, a mapping facility, and many other features.
• Developed by Joe Taylor, K1JT.
• System Requirements:
• SSB receiver or transceiver and antenna.
• Computer running the Windows, Linux, FreeBSD, or OS X operating system.
• 1.5 GHz or faster CPU and at least 100 MB of available RAM.
• Monitor with at least 800 x 600 resolution.
• Sound card supported by your operating system and capable of 48 kHz sample rate.
• If you will transmit as well as receive, an interface using a serial port to key your PTT line or a serial cable for CAT control. Linux and FreeBSD versions can also use a parallel port for PTT. Alternatively, you can use VOX control.
• Audio connection(s) between receiver/transceiver and sound card.
• A means for synchronizing your computer clock to UTC.

Richard’s setup:

• Yaesu FT-897D Transceiver.
• G5RV Antenna.
• Rascal GLX sound card interface.
• Ubuntu 9.10.
• 3 gigs of memory and an Intel 3.0 Ghz CPU.
• Onboard sound card.

Installation:

• Richard downloaded what looked like the .deb package from the web site.
• He used Gdebi to unpack and install it, but could not get it to stay running. Every time he tried to do anything it crashed.
• After reading the Linux installation instructions from the user guide, he attempted to install it in the manner described:
• Download the appropriate file from http://physics.princeton.edu/pulsar/K1JT/wspr.html, place it in your home directory, and run the following commands in a terminal

$ sudo dpkg --instdir=. -i wspr_2.00r1714_i386.deb
$ cd WSPR
$ ./wspr

• This resulted in a program that would receive after some fooling around with the sound card, but no rig control, and no transmit.
• As a last resort, Richard downloaded the Windows version and loaded it under Wine, which gave him rig control, transmit, and receive, without much of a problem.
• It did leave him with a few minor annoyances: he has to start it from the file manager with “Open with Wine” from the directory “.wine/Drive_c/Program Files/WSPR”. The menu bar at the top was only partially functional, but he thinks it has to do with his USB mouse, as keyboard control works fine.
• Richard was heard in Argentina on 40m running 5 watts and reported on the wsprnet site.
• WSPRNet website
• WSPR net offers a wide variety of information on the network in real time.
• Page of stations currently active on WSPR.
• Map of stations that can be filtered by callsign and/or band.
• Offers dicussion forums for Q and A, setting up schedules, and general WSPR discussion.

A short while ago, Canonical released the latest version of Ubuntu:  the fabled Maverick Meerkat, 10.10. This is the latest in Ubuntu’s normal release cycle and is not LTS. I had occasion to upgrade a couple of my personal computers running Ubuntu to the wily Meerkat. Find out what’s new in 10.10, and what’s old, in the first segment of LHS #049.

After that, Richard and I tackle the WSPR protocol for ham radio again. When it was discussed the first time around, neither of us had much of an idea what it was or how it worked. Armed with a broader understanding and a lot more experience, we talk about what works and what doesn’t work with WSPR, how to get it up and running on your system and what we like and don’t like about it.

Following that it’s on to witty banter, a passel of badgers, some hijinks, censorship, feedback and more entertainment than you can shake a wet hedgehog at. Thanks for tuning in. We love you all.

As I was roaming around the Intertubes, I came across an article at AmateurRadio.com written by Jeff, KE9V. I had been an avid listener of Jeff’s “Cornbread Road” podcast while he was publishing it as a podcast. The format was different enough to keep me interested. When it went away, I was highly disappointed.

As it turns out, his recent article disappointed me quite a bit as well. I don’t want to give much away, but suffice it to say the outlook Jeff paints is fairly bleak. At the same time, some of the points are valid and overall the essay was fairly thought provoking. Because of that, Richard, Bill (KA9WKA) and myself decided to discuss Jeff’s recent article. We also have our usual assortment of announcements, banter, gripes and response to feedback. So settle in for an interesting episode. We all had a good time. We hope you do, too.

Hello, everyone! Due to Cheryl having some hand surgery and my being a telecommuter for the last month or so, I haven’t been able to keep up with the podcast release cycle.  We’ve been recording episodes like we’re supposed to. It’s just been impossible to get them released on time. That means that #047 and #048 are going to be released in rapid succession so you’ll get twice the LHS yummy goodness.

This time around, Richard has been looking a little deeper into CQRlog, a great logging program for Linux created by OK2CQR.  We talked about this program in a past episode and we’ve mentioned it a few more times in passing. This time we’re getting down deep into the features and all of the integrations CQRlog has with other ham radio applications. We also address our usual announcements, feedback, other technical topics and throw in a bunch of witty banter just to keep things interesting. Thanks, all, for staying with us while we try and get back to a regular podcasting cycle. Keep listening and keep spreading the word.
