Being DX - Tales of a Contest Expeditioner

This collection of anecdotes from a dozen contest operations outside the "lower 48" describes both the unique aspects and common threads of our expeditions.  Non-hams also find this entertaining.

Prepare for the Worst - Overcoming Operating Challenges in The Gambia

Our 2003 CW Worldwide DX Contest operation at C5Z presented numerous and formidable obstacles that required a team effort to surmount.  This is a case study in "making it work - no matter what" with lessons that apply as well to emergency communications as they do to contesting.

Sharpening Your Emcomm Operating Skills

This interactive session includes both formal presentation and participant activities in the areas of tactical callsigns, message copying, net operations and callsign recognition.  It helps to have some room to spread out for this one, and having tables available is a plus.

NVIS - The Ultimate Backup in Reliable Regional Communication

Those involved in public-service communications have a tool that doesn't depend on repeaters or other infrastructure: HF using near-vertical-incident skywave, or NVIS.  This presentation describes the propagation characteristics, antenna choices and band selection involved in utilizing HF for regional communication.

Choosing the Right Coaxial Cable

I gear this primarily toward newer and less technically sophisticated hams and discuss cable characteristics, losses versus operating frequency, connector choices and more.  There's a little math, but the talk is more strategic than it is technical.  This typically runs less than 45 minutes, so brief coverage of a compatible topic (e.g., Antenna Gain - When, Why and How) for the same type of audience could be included.

Emergency Power - Loads, Sources and Management 

This presentation helps an operator to plan for limited-power situations. Topics include equipment selection and mission parameters; developing a power budget; generator and battery safety; battery types and selection; wiring, distribution and fusing; and alternative power sources (e.g., solar).
