Joe
Everhart, N2CX
"QuickieLab Test
Bench"
I'm proud to say that Joe has been my 'cohort
in crime' here in the NJQRP Club over the last 7 years, and along the way has
become my best friend as well. We've all been graced by his insight in
RF design and pragmatic approach to development of kits, antennas and field
operations over the years. Recently, N2CX has been focusing on a
new and flexible QRP experimenter's platform we developed together called the
QuickieLab. His initial guidance to QRPers concerning how to build and
use the QuickieLab have been published in the QRP Quarterly and QRP Homebrewer
magazines ... and Joe's presentation at Atlanticon this year pulls it all
together to show the big picture in the form of the 'QuickieLab Test Bench'.
N2CX has a passion for test equipment, and he'll describe how the NJQRP
QuickieLab is a great platform with which to build a ham measurement and test
bench. The Inherent BASIC Stamp 2 functions, the QuickieLab features, the
IOX chip (Input Output eXtender) and DDS daughtercard (Direct Digital
Synthesizer) together form a powerful collection of tools with which one
can implement a wide variety of test equipment. We will see how the basic
hardware plus some added interface circuitry can be used to make a powerful,
modular and integrated test bench consisting of a DC voltmeter, frequency
counter, signal generation, AC/RF voltmeter, SWR meter, RF power meter,
remote-reading field strength meter, antenna analyzer building blocks, sweep
generator/detector, two-tone generator, digital thermometer, comparative
headphone tester, semiconductor parametric tester, VFO, signal tracer ... and
the list goes on even more! I've read Joe's paper, destined for the
Proceedings that everyone gets, and its terrific! And so will be his
presentation.
You don't want to miss this N2CX presentation,
with live demonstrations of the QuickieLab Test Bench -- it'll be a classic!
About Joe Everhart, N2CX .....
Joe Everhart, N2CX is product of "space age" as his
imagination was fired by technology during those heady days. First by
necessity and later by inclination, he has always been a homebrewer.
With over 25 years in the aerospace industry, Joe has learned the hows and
whys of all that neat stuff he's built along the way - and sometimes knows
that it shouldn't work but does anyway! Having worked on everything from
LF antennas through the S-band comm system on the ISS Alpha, Joe loves to roll
his own and then to write about it to help others learn what this radio stuff
is all about. He is a radio-active member of NJ-QRP deeply involved in
the popular homebrew kits offered by that club. He even gets on the air
once in a while to check his homebrew rigs and antennas in QRP contests, as
well as from portable locations at hotels in strange cities.
