Introduction:

• Richard is looking forward to winter in Texas… all three days of it.

Announcements:

• Subscribers to LHS now have access to the Etherpad, or via the Etherpad link in the Content area of the LHS website.
• Black Sparrow Media now has a Twitter feed at BSM_Network.
• Richard rants: Ubuntu has added a nag screen to the download page requesting a donation.
• Linux Distributions for Ham Radio:
  • Has Shackbox died? There does not seem to be much activity since 2009.
  • Andy’s Ham Radio Linux CD by Andy, KB1OIQ, revisited. Version 11 was released in June, 2012, and is based on Ubuntu 11.10. Several of the tools have been updated to newer versions. Also at http://kb1oiq-andysham.sourceforge.net/
• Jeff Hodsdon published a list of influential ham radio operators, and neither Richard nor Russ are on that list! For shame!

Topics:

• Russ and Richard interview Scott, N8VSI, our LHS ambassador at the 2012 Ohio LinuxFest. He had demos of xastir, fldigi, yfktest, and others. Scott had two computers running and a Raspberry Pi. Sadly, the official LHS banner didn’t show up until two days after the event. Scott is a member of the West Chester Amateur Radio Club which operates from the Voice of America Bethany Relay Station.

Feedback:

• The Old Texas Engineer sent an audio response to Episode 88 about High Speed Multimedia and mesh networks. He gives us some history of HSMM in Texas and his experiences with the technology. He mentions the Open Mesh project and the South Texas Balloon Launch Team website.

The latest episode of LHS is upon you! Prepare to be astounded, mesmerized, blown away and flabbergasted. If none of that happens, perhaps you’ll be entertained and informed. In a music-less episode, we somehow manage to get through without stumbling–more or less. Our foray begins in the world of Linux and computing with some tips on how to make your desktop and your blog look better, at only the cost of your immortal soul. In the middle we touch on Hurricane Sandy and emcomm and follow that up with some Echolink: native on Linux Echolink, yeah! Feedback winds up the episode and then we go back to our respective holes in the wall. Send us feedback, if you get a chance. We’d like to hear from you.

Hello and welcome to a very late release of LHS Episode #093. Recorded about a month ago, I finally found the time to get this one edited and put out so the world can experience it. I’d like to thank our loyal listeners for their patience, and I sincerely hope that this episode stands up to the fine quality (*snicker*) that you’re used to from LHS. We get a visit from one of the show’s ambassadors in this episode who tells us all about his experience ambassadoring for a Linux event in Ohio. You know the one. Surrounding that are some interesting Linux topics, a ham radio discussion or two and a very informative bit of feedback from the Old Texas Engineer. You don’t want to miss it.

Introduction:

• The earth moved in Texas, recently, which sends Richard down memory lane.

Announcements:

• Texoma Hamarama will held October 26-27, 2012 at the Ardmore Convention Center in Ardmore, Oklahoma. Pre-registration ends October 20th.
• The Augusta Hamfest will be Saturday, October 13, 2012 in Augusta, GA.
• Scott, N8VSI, was the LHS ambassador at the Ohio LinuxFest, September 28-30, 2012. We look forward to hearing a report from Scott in the near future.

Topics:

• Richard recounts his experience replacing a computer power supply. Moral? Don’t be afraid to try repairing a computer yourself. Swapping parts is easier than you might think. For power supplies, pay attention to the wattage required. (Ed. Note: When in doubt, it’s best to replace the bad supply with one that has the same or greater wattage rating.)
• Departing from our usual topics, Russ and Richard discuss a couple applications for producing slide shows and panoramic photographs:
  • Imagination is a lightweight and simple DVD slide show maker for Linux and FreeBSD that’s very easy to use, offers a wide variety of transitions, supports background music, and much more. Available in the Debian and Fedora repositories, and probably many others.
  • Hugin is a program that allows you to assemble a mosaic of photographs into a complete, immersive panorama, stitch together any series of overlapping pictures, and much more. It’s cross-platform and easy to use.
• Why Ham Radio? Richard talks about why you might wish to obtain an Amateur Radio License and how you can combine it with Linux, including:
  • Getting your ham license for our non ham listeners.
  • There are many modes of communication, including voice, Morse code, and many digital modes.
  • The ease of getting your license.
  • Why you should get your license.
  • How to get your license.
  • The Amateur Radio Relay League (ARRL) is a good source of information
  • Free practice tests are available at qrz.com
  • A list of certified Volunteer Examiner Coordinators is available at www.ncvec.org.
  • Test sessions can be found through the ARRL and many local radio clubs.
• Russ describes Universal Plug ‘n’ Play devices (UPnP). Many new devices offer the ability to play media from UPnP servers. It makes sharing your media very convenient and easy, but can also be a security risk.

Feedback:

• Pete, VE2XPL, sends a long email in response to episode 88, and covers such things as the Toonie, Alexandre Graham Bell, Brad Sucks, the wAVEgUIDES PodCast, SouthCARS, email addresses for LHS, and the MintCast.
• Ted, WA0EIR, asked if there is a problem with the LHS mailing list as his attempts to post a message there “bounced”. Yes, the mailing lists have been broken, but they’re fixed now.
• Larry Bushey of the Going Linux podcast says thanks for the great show, and admits they stole the LHS “badger” sound effect for use on their show. Episode 185 contains an example of their use of the Badger.
• LHS was mentioned in a comment to a post at hak5.org.

Welcome, everyone to Episode #092 of Linux in the Ham Shack. In order to bring some more Linux users into the fold, we spend some time addressing issues pertinent to them. The first segment discusses some useful video and photo editing software that might be of interest to anyone, ham radio operator or not. The second segment discusses the ease of getting into the amateur radio hobby and how computer enthusiasts can use that shiny new license to expand their computing horizons. Third and finally, we respond to listener feedback. Catch you in a couple of weeks for the next go-around.

Introduction:

• It’s Second Spring in Texas, and Autumn is beginning in Arkansas, so sit back and enjoy another exciting episode of LHS.

Announcements:

• Paid subscribers to LHS may have noticed the web site certificate had expired. That problem is fixed.
• Welcome new subscribers Michael S., Michael C., and Bill A. Thank you!
• Sign-up for the LHS mailing list.
• Our LHS Ambassador to Ohio LinuxFest will be Scott, N8VSI. Thanks, Scott, and we look forward to hearing all about it.
• Please donate to the podcast and click on the affiliate links on the website.

Topics:

• HF Antennas, Horizontal vs. Vertical
  • Tonight, our hosts discuss the pros and cons of horizontally and vertically polarized HF antennas.
  • One thought is that once the RF radiation hits the various layers in the ionosphere, the polarization doesn’t really matter much as it gets reflected to and fro.
  • Richard offers the practical reason for preferring horizontal antennas for HF: it’s easier to build and erect the long antennas necessary for these frequencies. However, for chasing DX, those long-distance contacts, many hams prefer vertical antennas as they tend to have lower angles of radiation.
  • Also mentioned: GAP antennas and the G5RV antenna.
  • Wire horizontal dipoles are inexpensive and easy to construct. Verticals are a good choice when space is limited and can have a lower take-off angle, providing a good ground radial system is installed beneath them.
  • Horizontal antennas can be more directional. A dipole wire running north and south will have a better propagation east and west. A vertical is omnidirectional, radiating equally in all directions. To complicate matters, a horizontal antenna lower to the ground will radiate at higher angles than the same antenna that is higher. This can be useful for communicating with stations that are close to you.
• A new section of the podcast: Russ’ Rant!
  • Russ has a Yaesu FT-7900R, a dual-band UHV/VHF mobile radio. It has a removable front panel, allowing the main part of the radio to be hidden and the display can be easily mounted on the dash. However, the speaker is on the body of the radio, so you can’t hear it if it’s hidden under the seat or in the trunk! Russ thinks the head unit should also contain a speaker, perhaps a very small one like in an mp3 player. Or put the speaker in the microphone.
• Returning to antennas, Richard recommends that KD8SZG (in the chat room), should try building his own wire antennas for HF. Any of the antenna books written by Doug DeMaw, W1FB, are good resources. His Antenna Notebook is one. (I also like the various ARRL antenna books, like the Simple and Fun Antennas for Hams. -Ed.)

Good mushroom, everyone, and welcome to another episode of Linux in the Ham Shack. This time around, we get a little bit ham geeky. That’s not a bad thing for those of you who are computer enthusiasts. We all delve into some scientific topics like electro-magnetic radiation, skywave propagation, atmospheric layers and other topics that are sure to tickle a few neurons and axons. We manage to keep everything at a level even non-geek-weenies will be able to understand. Somehwere in the middle, Russ goes on a tirade so you don’t want to miss that either. While you’re listening, take a moment to click on a link or two, sign up for the mailing list or maybe donate a couple of bucks to the show. We will love you long time if you do. Promise.
