Prerequisites:
Ok folks, here are the prerequisites for the elmer project. This list
was compiled with the help of the "elmers" so we can get a head start on
the theory. Please read this carefully if you plan on participating in
the class.
1) All posts regarding the elmer project must have a subject that starts
with elmer101:
2) Students must have access to the ARRL Handbook, 1995 or later (1998
preferred).
This can be obtained directly from the arrl or other (discounted)
sources ( i.e. http://www.amazon.com , local and mail order Ham radio
dealers)
The following references are extremely helpful but not required.
a) Solid State Design for the radio amateur
arrl has this book.
b) Databook for homebrewers and QRPers by NA5N
Paul Harden has agreed to provide this book at
a substantial discount
for the people in the class. I will post the info shortly.
******************************************
Here is the information on how to obtain a discounted copy of
"Electronic Databook for Homebrewers and QRPers" by Paul Harden.
Although it is not _necessary_ to have this book in order to participate
in the class, it provides a wealth of information on the subject.
The book has nearly 200 pages
of data sheets covering discrete components (capacitors, resistors,
transistor specifications, etc.) to specific Integrated Circuits used in
HF communications (NE602, TL082, LM386, etc.). Additionally, a detailed
circuit analysis of NE602 based QRP rigs with o-scope and spectrum
analyzer waveforms is presented in the first section. The book is
5.5x8.5 pages, wire-spiral bound to lay flat on the workbench.
Anyway, order information is:
Data Book for the Elmer 101 project is $18 ... which INCLUDES shipping
to US/VE address. (Add $3.50 for DX shipping). Send orders to:
Quicksilver Printing
P.O. Box 757
Socorro, New Mexico 87801
All outgoing books for the Elmer 101 Project will be autographed by NA5N

3) Access to a scientific calculator (or pc program equivalent)
4) Graph paper
5) Access to a Digital Volt Meter (DVM) of reasonable quality
6) 50 ohm dummy load
7) RF probe (plans are in the ARRL HB)
8) Soldering equipment (iron, solder, solder wick, etc.)
9) Diagonal cutters, long nose pliers, screwdrivers, wire strippers,
exacto knife.
10) A good magnifying glass
The student must learn the following concepts before the project starts
in late March. The technical posts will assume this level of knowledge.
The info can be found in the ARRL Handbook. I will post the page numbers
for each section as soon as my book arrives (today?). If you need help
ASK!!!!
1) Ohm's Law
2) Kirchoff's law for voltage and current.
3) Capacitive and inductive reactance X(c) and X(l)
4) Resonance and Q
5) AC and DC voltages and power, phase, p-p, RMS, etc.
6) Electronic component recognition
7) Basic soldering (Practice!)
The student must have web or FTP access to the internet. If you don't,
please contact me ASAP so we can figure out how to get the info out to
you.
