LHS Show Notes #072
Introduction:
- Happy New Year! Sorry for the delay in releasing the last several episodes.
Announcements:
- Would you be interested in the return of Resonant Frequency, the Amateur Radio Podcast, if it cost a dollar an episode? Send your thoughts to Richard via email at [email protected].
- Black Sparrow Media now provides an aggregate RSS feed of Linux in the Ham Shack, QSK Netcast, and Resonant Frequency. One feed, three shows! Quite a bargain.
- There is now a (free) Black Sparrow Media mobile app for the iPhone, iPad, iPod Touch and Android! See blacksparrowmedia.net for details, and send us your feedback.
- Andrew, AC8JO, has a blog that discusses Linux, amateur radio, and other topics. Naturally, he mentions our podcast. Thanks, Andrew!
- Leif, KC8RWR, responded to our comments in episode 67 that Apple created CUPS. According to Wikipedia, CUPS, the Common UNIX Printing System, was developed by a Michael Sweet beginning in 1997, and was later adopted by Apple for OS X. In 2007, Apple hired Michael Sweet and purchased his source code. The Apple website provides a somewhat different version.
Thanks for the information, Leif. Our advice is to pick the story you like and stick with it!

Topics:
- Channel Bonding for Linux
- Channel bonding combines two or more network interfaces on a host computer for redundancy or greater bandwidth.
- By bonding two or more Ethernet links to your computer, you get several benefits, including redundancy, so if one network port fails, the other still works, and greater bandwidth when both (or more) links are running.
- Based on the Link Aggregation Control Protocol (LACP), though called different things depending on vendor, such as EtherChannel or PortChannel.
- It’s relatively easy to set up. Briefly:
- You’ll need an Ethernet port for each link, set up and configured in the normal manner. These ports will likely be called eth0, eth1, etc.
- Install the ifenslave package, which allows you to create a “bond” interface, say bond0.
- Create modules.conf file to alias the various ethx devices as bonding interfaces.
- Modify your /etc/sysconfig or /etc/network/interfaces file (depending on your version of Linux) to include an entry that references the bond0 interface.
- ifup the bond0 interface, and all the component interfaces should come up.
- Other configuration settings will set up the failover time.
- Resources:
- http://www.linux-corner.info/bonding.html for Red Hat-based systems.
- http://wiki.debian.org/Bonding for Debian-based systems.
- Ethernet bonding on linux (Debian based)
- Ethernet Bonding Configuration in Debian
- Bonding
- Our hosts then discuss the utility of load balancing between multiple network interfaces.
- More about the apt-cache utility
- Russ provides more information about the apt-cache utility for Debian-based systems, previously discussed in Episode 69.
- The basic syntax of the utility is apt-cache [command] [package(s)]. There are many commands you can use, including:
- policy [package] shows which repository provided, or would provide, a specified package.
- depends [package] shows all packages in the repositories that depend on the named package, and which other packages would be installed or suggested.
- showpkg [package] shows reversed dependencies; that is, which packages depend on the named package, and the MD5 checksum of the package.
- stats shows some aggregate sums about all the packages in the repositories included on your system. For example, on Russ’ system:
Total package names: 42814 (856 k) Total package structures: 42814 (2,398 k) Normal packages: 32874 Pure virtual packages: 374 Single virtual packages: 3670 Mixed virtual packages: 465 Missing: 5431 Total distinct versions: 33706 (2,427 k) Total distinct descriptions: 33706 (809 k) Total dependencies: 200360 (5,610 k) Total ver/file relations: 35248 (846 k) Total Desc/File relations: 33706 (809 k) Total Provides mappings: 6402 (128 k) Total globbed strings: 197 (2,192 ) Total dependency version space: 789 k Total slack space: 65.4 k Total space accounted for: 11.5 M - unmet shows packages in the repositories with unmet dependencies in the tree, that is, if you attempted to install, would fail.
- show [package] shows meta information about the package. For example, “apt-cache show adduser” returns:
Package: adduser Version: 3.113 Installed-Size: 1100 Maintainer: Debian Adduser Developers Architecture: all Replaces: manpages-it (<< 0.3.4-2), manpages-pl (= 5.6.0) Suggests: liblocale-gettext-perl, perl-modules Description: add and remove users and groups This package includes the 'adduser' and 'deluser' commands for creating and removing users. - 'adduser' creates new users and groups and adds existing users to existing groups; - 'deluser' removes users and groups and removes users from a given group. Adding users with 'adduser' is much easier than adding them manually. Adduser will choose appropriate UID and GID values, create a home directory, copy skeletal user configuration, and automate setting initial values for the user's password, real name and so on. Deluser can back up and remove users' home directories and mail spool or all the files they own on the system. A custom script can be executed after each of the commands.

- Tim Allen’s character in his latest TV show, “Last Man Standing” is a Ham Radio Operator, KA0XTT.
Feedback:
- Kevin, KC9VAN, writes that he’s enjoying the show and just recently received his ham radio license. He also notes that he’s had the most luck with Hewlett-Packard printers under Linux. Thanks, Kevin. Russ has had good luck with Dell printers and generic PCL drivers.
- Leif, KC8RWR, posted several comments about episode 67. He suggests avoiding “all-in-one” printers, and instead, using separate printers and scanners. (I agree! -Ed.) Often, used scanners can be had for very little money. Leif also suggests buying printers with separate cartridges for each color. That way, you’re not throwing away all the colors when just one is empty. He seconds Russ’ suggestion to use a laser printer over inkjet, as the cost per page is less.
- Russ likes the Epson Artisan 835, especially for printing on CDs and DVDs, and it works well with Linux.

LHS Show Notes #071
Announcements:
- The Black Sparrow Media web site has been updated. If you use the aggregate feed from there, you’ll receive Linux in the Ham Shack, QSK Netcast, and Resonant Frequency (or Richard’s Radio Adventures) podcasts.
Topics:
- D-RATS
- Bruce, VE2GZI, asks for help installing D-RATS on his Linux Mint computer. He tried adding the repository per the instructions on the D-RATS website, but received errors.
- Richard has several suggestions: Make sure the whole line “deb http://d-rats.com/apt karmic release” gets entered into your sources.list file and that you are using the right repo for your distribution. Linux Mint normally falls a version behind Ubuntu. You might also try the tar file labeled “source” from the website, and use the archive manager to install it. Since D-RATS is written completely in Python, and Dan normally tries to stay with the most current version, check to see if you have the most recent version of Python installed. Finally, you could subscribe to the D-RATS mailing list from the website for more help.
- Russ adds: If you wish to add the repository via the command line, there are a couple of ways to do it: (a) Edit the file /etc/apt/sources.list and add the “deb http://d-rats.com/apt karmic release” line, OR (b) Create a file in the /etc/apt/sources.list.d directory called, say, d-rats-repo.list, and add the “deb http://d-rats.com/apt karmic release” line to it. However, back in April, 2011, Steve Conklin, AI4QR, said his packaging of D-RATS had been accepted into both Debian Testing and Unstable branches. So, if you’re running Debian or Linux Mint Debian Edition, it’s already in the repository. Just issue the command “apt-get install d-rats”. For Ubuntu, there’s a PPA at https://launchpad.net/~sconklin/+archive/hampackages. That should work with Ubuntu 10.04 (Lucid Lynx), 10.10 (Maverick Meerkat), and 11.04 (Natty Narwhal). (It may not work with Ubuntu 11.10, Oneric Ocelot, but then again, it might).
- Ed. Note: After this episode was recorded, the D-RATS website was updated to say:Ubuntu users should use the ubuntu-hams PPA in order to get packages for D-RATS. To install the PPA, go to a terminal and type:
sudo apt-add-repository ppa:ubuntu-hams-updates/ppa sudo apt-get update sudo apt-get install d-rats
The package manager will do the rest!
- Chirp
- Chirp was written by Dan Smith, KK7DS, who is also the author of D-RATS.
- From the Chirp wiki: CHIRP is a FREE cross-platform, cross-radio programming tool. It works on Windows and Linux (and Mac OSX, with a little work). It supports a growing list of radios across several manufacturers and allows transferring of memory contents between them.
- Chirp currently supports 41 different model radios from Alinco, Yaesu, Kenwood, Icom, and others.
- Richard tested it with his Icom IC-91 and IC-2200.
- Chirp has a bare-bones interface, using a basic spreadsheet style, and is primarily for entering memory channel information. It will allow entry of call signs for D-STAR operation.
- There are packages for Fedora and Ubuntu, and a source package for all other distributions of Linux. Chirp is written in Python, so be sure to have the latest version of Python installed.
- There is also a self-extracting .exe file for Windows, and an app package for Mac OS-X. You must install the Python runtime package, available on the Chirp website, for the Mac version.
- There is a Chirp mailing list, among others, at http://intrepid.danplanet.com/mailman/listinfo/.
- Russ and Richard then discuss the cost of various D-STAR radios.
- Linux Tip: apt-cache policy
- Russ offers a tip on how to determine which Debian repository is providing a given package.
- Use the command apt-cache policy <package name>
- For example: apt-cache policy libpulse0
- The results of that command will show you which version is installed, if any, which version would be installed, and all other versions available.
Feedback:
- Dan, K4FD, thanks us for the podcast. It has inspired him to return to the hobby after a 10 year hiatus. Thanks, Dan, and welcome back to the hobby!
- We received a donation from Jim G. Thank you, Jim!

LHS Show Notes #070
Promo:
- The 2nd Annual Northeast GNU/Linuxfest will be held March 17, 2012 in Worcester, MA.
Introduction:
- Welcome to another installment of Linux in the Ham Shack.
- After the holidays, consider attending a Skywarn training class so you’ll be prepared for the next storm season.
Topics:
- Contesting software for Linux
- Ian, KM4IK, wrote that he’s now using Ubuntu 11.04 in his ham shack, but wants suggestions for a native Linux contest logging program. Good question, Ian, and we have a few suggestions. However, as neither Russ nor Richard are contesters, these may or may not be suitable for you.
- JL Logger is a Java application that supports all of the major contests.
- YFKlog and YFKtest are curses-based programs that run in a terminal session. YFKtest uses the hamlib libraries for rig control.
- TLF also runs in a terminal session and uses hamlib for rig control.
- KB is still in development. It runs in the Gnome window manager. Radio control for the Yaesu FT-1000 only.
- Fldigi has a built-in logger, and will also work with CQRLog.
- N1MM Logger has been reported to work under Wine. Others have had problems.
- Russ tried installing N1MM under Wine, and while the installer ran fine, N1MM didn’t run properly when launched. Apparently, you must have the ALSA libraries installed. Note that the N1MM website warns that you should perform the Full Install, then install the latest update. Do not run the Full Install without first installing the update. Russ also tried the JL Logger, but it crashed. After realizing that it requires that the Java Development Kit, he installed that, but it still crashed. Look for an update in a future episode.
- VLC media player
- Richard was having an issue with the VLC plugin for Firefox 7.0.1; the LHS music stream would play one song then stop. The VLC Media Player should work.
- Our hosts briefly digress into a discussion of the DEFCON system; DEFCON 1 is the most serious, while 5 is the least. Hollywood often gets it wrong.
Feedback:
- Burt, K1OIK: please contact us about recent emails we’ve received from you. It may be that your email account may have been compromised.
- Leif, KC8RWR, wrote us regarding the discussion of EchoLink clients in episode 66. He tried QTEL and it worked fine. Thanks, Leif. (Also look at SvxLink.)
- Tom, KA2D, who is on the committee for Ham Radio University in New York, asks if there are any LHS Ambassadors in the Long Island, NY area. No, Tom, so you’re it!
- Andy, KC2ZWR, of the Suffolk County Radio Club, will also be at Ham Radio University on January 8, 2012, and offers his services as ambassador for that event.
- Tony, K7ISS, wrote to say he was happy that Richard had a good time at the Texoma Hamarama. Richard blogged about his visit to the event.
- Mike S., sent a VERY generous donation to the podcast. Thank you, Mike!
- The second annual Indiana Linuxfest will be April 13-15, 2012 at the Wyndham Indianapolis West Hotel. Russ is planning to be there, and so should you.

LHS Show Notes #069
Introduction:
- Welcome back to another episode of LHS.
Topics:
- Texoma Hamarama
Richard attended Texoma Hamarama at the Ardmore Convention Center in Ardmore, OK. He had a great time and describes his adventures. He took a few pictures and wrote a blog entry for the web site. - HamQTH
HamQTH is a callsign lookup service that is free and does not require a subscription. Russ gives his review. By registering, you can edit some of your information or use the search results in your logging program. Thanks to Ted, WA0EIR, for telling us about it. - Adventures in Printing
- Richard recently installed Linux Mint on his wife’s machine as she was becoming increasingly frustrated with the speed of Windows. He did run into an issue with getting her Lexmark all-in-one printer working, which leads him to a discussion of printing in Linux.
- CUPS, Common Unix Printing System, originally developed by Apple for OS X, has become the standard printing system for Linux. You can administer CUPS by pointing your web browser to http://localhost:631
- Most distributions install the Foomatic driver database. Another source of drivers is Gutenprint.
- If your printer is not listed specifically, you may have success using a generic PCL5, PCL6 or Postscript driver.
- Also check the Linux Foundation OpenPrinting project to see how well a given printer is supported in Linux. It’s a good idea to visit this site before you buy the printer.
- Most network printers will be recognized and configured automatically by CUPS.
Contact Info:
- Contact Richard at [email protected], Russ at [email protected], or both at the same time at [email protected].

LHS Show Notes #068
Introduction:
- Who has a drawl?
Announcements:
- Richard has been reading about Ubuntu 11.10, “Oneiric Ocelot”, due to be released on October 13th. Our hosts hope to have some sort of review in the near future. Richard is also considering trying KDE. (The version of Ubuntu with KDE as default is Kubuntu.)
- Look for another episode of Richard’s Radio Adventures in the near future. It’s recorded mobile, and Richard wonders how to reduce the road noise with Audacity. Russ offers some advice on training the noise removal plug-in for Audacity.
- Richard did not make it to the Belton hamfest this year, but maybe next spring. He’s looking forward to attending the Texoma Hamarama, October 21 – 22, 2011 at the Ardmore Convention Center, 2401 North Rockford Road, Ardmore, OK.
- Richard is recruiting hams for the Kaufman County (TX) ARES group. Please visit the KCARES website for more information.
- Richard re-tells the infamous badger story. Speaking of badgers, you can find the Kiss My Badger tee-shirt, and a lot of other good stuff, at the LHS store.
Feedback:
- Danny inquires about an easy-to-use distribution for a senior and computer novice, perhaps Linux Mint. Our hosts suggest Linux Mint and PCLinuxOS. Note that the Mint live CD does not include the codecs, but the DVD does. If you install from the CD, you can install the codecs later.
- Danny also asks if there is a way to ask the Mumble developers to support screen-reading software. Since Mumble isn’t a GTK-based application, it’s probably not well supported under Orca. You may wish to raise your concerns on the Mumble forum, or on IRC at irc.freenode.net, #mumble, or click the Live Chat Now button on the www.mumble.com website.
- Burt, K1OIK, left a comment regarding Episode 61 entitled “South of the Border”: “I’d like to go south of your borders!” We’re a little worried about you, Burt.
- Michael, KD8GIJ, asks for instructions on removing a dual-boot installation of Linux Mint if he decides he doesn’t like it. You can, of course, just wipe the whole drive and reinstall Windows. You may be able to boot the Windows install media and let it “repair” your installation. However, you don’t really need to remove grub; just make Windows the default and remove Linux from the grub menu. If that’s not acceptable, you’ll likely have to wipe and reinstall Windows to return it to the pre-Linux state.Other suggestions include:
- install Mint as a virtual machine with Virtual Box.
- use the Windows Ubuntu Installer (wubi) which will also allow you to uninstall Linux after testing.
- install Linux to a flash drive and boot and run from that to try it out
- make an image of the Windows drive before installing Linux, perhaps with PartImage or Clonezilla, and you’ll have an easy means of returning to the pre-Linux-install state.
- John “The Nice Guy” Spriggs, G7VRI, asks about a live Linux distribution reviewed in Episode 62 that contained software to run EchoLink. (I think he’s referring to Andy’s Ham Radio Linux CD). svxlink is the Linux-native EchoLink client, but it is CLI-driven. The Windows client does run well under Wine. You may want to look at qtel, another Echolink client. It’s an older application. In fact, svxlink is based on Qtel.
- John also wonders if the music played on the show is Creative Commons licensed. While most of the music is Creative Commons or podsafe, the music in Episode 62 is not CC or podsafe, but Russ did have permission from the artists to play them.
- John pointed out that the description tags in the podcast audio files were empty. Thanks, John, and rest assured that Russ will be adding descriptions as time permits.
- By the way John, please contact Richard at the email address below as you may be able to help him with some music for another project.

LHS Show Notes #067
Introduction:
- It’s a ramblin’ show tonight.
Announcements:
- Texoma Hamarama 2011 will be October 21-22, 2011 at the Ardmore Convention Center, 2401 North Rockford Road, Ardmore, OK. Richard hopes to be there.
- If you attended the Huntsville, AL hamfest in August, let us know if you think it would be a good venue for LHS.
- Thanks, as always, to Gamma Leonis for the theme music.
Topics:
- Russ talks about the antenna feedline window passthrough panel he bought at Dayton. He’s also hoping to get a radio in his truck. Richard describes the window passthrough methods he’s used in the past, with foam pipe insulation or air conditioning insulation foam.
- Richard talks about the lack of ham radio activity in his area (Kaufman County, TX): no club, no RACES group, no ARES, etc. He called his ARRL SEC (Section Emergency Coordinator), Walt, KG5SOO, and learned that the local groups weren’t happy with the current ARES manager. The SEC says paperwork is being processed and the new emergency coordinator of Kaufman County, TX is Richard, KB5JBV! Currently, there are just two ARES members, Richard and the Emergency Manager, so if you’re in Kaufman County, TX, get in touch with Richard! (Congratulations, Richard!)
- There’s a new podcast out there: Richard’s Radio Adventures. Look for it on the Resonant Frequency feed.
- In Linux-related news, Russ lets us know that kernel.org was hacked a few weeks ago. Because the code was in an encrypted git repository, it was safe, but they moved it to github, anyway.
- Russ also says there was a brief period that GNU Emacs was packaged and distributed with a binary blob in it, which violates the GPL. It’s since been fixed.
- A security hole in SSL/TLS has been reported.
- Simon, HB9DRV, has sold the rights to his Ham Radio Deluxe software. Our hosts discuss the possible ramifications.
- Richard wanders into a discussion of Arch Linux. It seems there was an issue with Arch not being free (as in speech). However, Parabola GNU/Linux is Arch, but free of all the entanglements.
- If anyone out there is an Emergency Coordinator or Assistant Emergency Coordinator, send an email to Richard about how your EC is going. Richard is looking for advice on how to best set up the ARES EC organization in his county.
- Russ admits that his other podcast, QSK Netcast, has stalled, mostly due to a lack of his available time.
- Since some parts of the LHS website are now subscription only, Russ began researching SSL certificates. He found a couple of places that issue inexpensive or free browser-compatible certificates: CheapSSLs , under $10 per year, and StartSSL will issue personal certificates for free.
- Russ and Richard discuss their love for the Sansa Clips. Russ likes DoggCatcher for listening to podcasts on his Android phone.
- Richard talks about his secret antenna project. He’s now in an area with Codes, Covenents and Restrictions (CCRs) which preclude outside antennas. Years ago, he bought an Arrow dual-band J-pole antenna, and used it for packet and other stuff. Using some military surplus olive-drab fiberglass tent poles, he strapped the J-pole to the top of the tent poles and the poles to the top of an 8′ fence. He assures the neighbors that it’s just a flower pot hanger.

LHS Show Notes #066
Introduction:
- Richard is still in the process of moving, but did get his WinLink rms gateway running as described in a previous episode.
Announcements:
- Jay Forrest has lauched The Linux News Podcast. The podcast will focus on topics such as software freedom, Linux development, Open Source software, Android and mobile devises, security issues, and Linux distribution releases. Our hosts offer their opinions.
- Ohio LinuxFest will be held in Columbus, Ohio on September 9-11, 2011. (Note: Russ will not be there, but maybe YOU can represent LHS. Visit the web site and look at the Ambassadors page to learn how.)
- Texoma Hamarama will be October 21-22, 2011 in Ardmore, OK. Richard might be there, so if you’re in the area, look for him!
Topics:
- Our hosts discuss the ARRL statement regarding HR 607, “Broadband for First Responders Act of 2011″. This bill provides for the re-allocation of the 420-440 MHz band, calling it part of the “Public Safety” spectrum. This is not the case, and we should contact our representatives and voice our opposition to this bill. The ARRL offers sample letters you can send to your representatives.
- Richard and Russ talk about various amateur radio programsfor Linux offered by Ted, WA0EIR.Russ built them all from the available source code on his Linux Mint Debian Edition 10 computer. In order to do so, he installed a number of development libraries:
- libmotif-dev
- libxmu-dev
- libxpm-dev
- libxbae-dev
These are header files necessary for the compiler to properly build the programs.
- Each program requires the following commands to compile and install. Change to the directory containing the program and type:
./configure ./make ./make-install
(You may wish to be root to perform the make-install command.)
- TWLOG – A basic QSO logging program. Useful for day-to-day logging, but not recommended for contest logs. It will export to ADIF. It requires the Xbae Matrix Widget.
- TWPSK – A simple bpsk/qpsk program. Co-written with Hansi, DL9RDZ
- TWCW – A Morse Code trainer that also allows keyboard CW operation.
- TWCLOCK – A world clock application that will also automatically send a CW identifier every 10 minutes.
- Check the /etc/X11/app-defaults directory for the “X resource” files to change the configuration options for these programs. For example, in that directory is a file called twclock that contains the callsign transmitted by TWClock.
- PSK31LX – A curses-based PSK31 program, so it runs in a terminal window or directly in a terminal session. For help, a man page is included. (Type “man psk31lx”.) It makes use of the arrow, control, and function keys. You can choose the audio and serial devices with command line parameters at start. Configuration parameters are stored in your home directory in the file .psk31lx.ini.
Feedback:
- Don, WS4E, asks for Internet resources for handicapped amateur radio operators. He’s familiar with the Handiham organization, but wonders if there are others.There are many newsgroups and mailing lists dedicated to hams with disabilities. A Google search should return several. The Canadian National Amateur Radio Society site Amateur Radio for the Disabled, has several useful links. Richard mentions Lighthouse for the Blind. The ARRL has a page listing several articles. There’s also a Facebook group, Blind Amateur Radio Operators.
- Petr, OK2CQR, the author of CQRLOG, responds to Torsten’s (K5TOR) problems installing CQRLOG on a 64-bit machine: CQRLOG already has native 64-bit version. There is no need to install the 32-bit version. You can use the ppa at launchpad.net with packages for Lucid, Maverick, Natty and Oneirc. Version 1.2.1 will be part of the Oneiric release as well. More information is here.
