I've been an Amateur Radio Operator (Ham) for more years then I care to remember. My level of activity has varied greatly, and most often it has been in support of Search and Rescue (SAR) activities. Here are a few links I've found useful:

• Amateur Radio & DX Reference Guide

• Amateur Radio Callsign Lookup 

• ARES of King County

• ARRLWeb: Hamfest and Convention Database

• Assembling Powerpole Connectors

• FCC License Renewal

• Ham Radio Outlet

• Puget Sound Repeaters

• QTH.com Ham Classifieds
  

• Rig tips, tricks, and modifications
