Here's the summary of our talk:

HF Pack and Portable Radios:
Designing for High-Performance and Low-Current-Drain

Presentation by:

Eric Swartz WA6HHQ
Wayne Burdick N6KR

Most modern, high-performance HF transceivers are far from portable. Their 
high current drain--as much as 3 amps on receive--relegate them mostly to 
fixed-station use. When such rigs are used for field operation, large 
batteries or generators are needed.

But it's possible to design high-performance gear that you really can take 
with you. Eric and Wayne, the designers of the Elecraft kits, will explain how 
their K2 transceiver tops the charts in receiver performance while drawing 
only 150-200 milliamps. They'll describe the current drain and performance 
advantages of a single-conversion, down-conversion system architecture, and 
touch on topics from latching relays to transflective LCDs to firmware-based 
power-reduction strategies.

This talk will appeal to both a technical and non-technical audience. You'll 
discover what's eating all those watts inside your desktop radio, and see how 
efficient rigs like the K2 can please the most demanding DXers and contest 
operators, yet retain the size, weight, and current drain of a go-anywhere 
portable.

Along the way, Eric and Wayne will answer the question, "What is HF Pack?" 
This rapidly-growing operating activity takes HF-portable operation to new 
heights--literally.
