The Columbia Linux User Group met on 11 September 2008 at 6:30 PM.

This month we had two talks:

(1) Shay Walters gave a brief discussion of the /proc filesystem in Linux. Topics covered included seeing process information and how to invoke the "Magic-SysRQ" key.

(2) Phil Moore gave a presentation showing several Amateur-Radio applications using Linux, including some which use the sound card in the computer to encode and decode data sent over the radio, as well as some that control radios that are equipped for such control.

Some memorable moments from Phil's impressive presentation on the wonders of ham radio:

  1. Bouncing ham radio off the moon using Moonbounce.

  2. Bouncing ham radio off the ionization field of passing meteors.
  3. The WSPRproject: communicating using the smallest signal possible.

Ham radio was used as the first emergency communication platform after the tsunami of 2004.

Ham radios are about the size of a car radio and cost about $800. Some ham radios are even handheld, costing $200-$300.

The meeting was adjourned around 8:00 PM.
