CQ WW SSB – 15m Open

15 meters is open to Europe from the east coast of USA.  You have to be greater than 4000 miles, less than 6000 miles, and the wind has to be blowing in the proper direction for those stations to hear me.  I missed on OH0 because they were just too close.  Since when is being between Sweden and Finland too close?

Amateur Radio Contest logging software for Linux

I’ve been looking for a good amateur radio contest logging program for Linux.  Little did I know that the solution was right under my nose!

fldigi is a great amateur radio program that will encode and decode almost any digital mode you can find out on the HF bands.  This morning I noticed a new mode: SSB.  Now I can’t confirm this but I’m pretty sure this isn’t a means of transmitting voice from your desktop but rather a placeholder for using fldigi’s awesome contest logger for your next voice contest.

I’ve used fldigi in contests before but they have been RTTY contests.  The log output works perfectly and allows me to immediately submit my log to the contest managers, to GlobalQSL for my bureau cards, and import the contest log to my traditional logging software CQRLOG.

I’ll be trying out this solution this weekend on the CQ WW SSB contest.  I’ll try to document my feelings on Monday.

Moving my Linux blog

Because this blog is basically my journal of Fedora activities I’m moving over to Fedora’s blogging solution.  I haven’t quite figured out how to move all my current data over but I’m sure I can get that completed in the next couple of days.

Please join me over at my new space and follow my new feed.  (Those following me on Fedora Planet will find that you won’t miss a thing!)

I’m going to need a few more Yubikeys…

Last week I received my Yubikey and promptly figured out how to use it with my Drupal installation using the Yubico authentication server.  Since then life got in the way and I haven’t had a chance to work on my other projects that I want to get working.  I did get a chance to do some research on the mechanics behind the Yubikey and figured out that I’m going to need a few more Yubikeys for all my projects.

The vulnerability I’m trying to combat is a replay attack.  This means that different AES keys are needed for each authentication server or replay attacks are a real possibility.

I have three uses for my Yubikey:

  1. Authentication to websites utilizing the Yubico authentication server.
  2. Authentication into Fedora servers using the Fedora authentication server.
  3. Authentication into my local computer using a local database.

I THINK I can setup my Yubikey to handle two of these using different profiles in the token but not the third.  Perhaps I’ll be able to get everything functioning soon.

Art Chimes missing from Our World

Okay, I’ve been caught.  I haven’t been keeping up with a program I used to make a point of listening to every week.  Our World, from Voice of America, is a weekly technology show that was always quite interesting to me.  The show’s host, Art Chimes, is a great guy whom I met a year, or so, ago.  Today I had some time so I grabbed last week’s show and played it only to be greeted by a strange voice.  Not that the new guy is bad but what happened to Art?!?

I looked back through the shows and found that his last show was on 30 April 2010.  Like I said, I haven’t been keeping up.  I hope Art is well.  I’ve seen a few stories published by Voice of America with his name prominently at the top so perhaps he is still around just sitting behind a different curtain.

Setting up nVidia drivers

At work I always forget this so this is a technical note for myself.  Maybe it will help you too?

  • Run lspci to determine what controller you have.
  • Visit the nVidia driver website and select your controller.
  • Stop X (telinit 3)
  • Download the file and chmod 500.
  • Verify you have gcc and kernel-devel packages installed.
  • Execute the program you downloaded from nVidia.
  • Start X (telinit 5)
  • Log in
  • Execute nvidia-settings
  • Activate additional monitor (twinview)
  • May have to enable Xinerama for more than two monitors.
  • Enjoy fruits of labor.
