First, you need to install the Arduino IDE (integrated development environment)
on your PC. Start at arduino.cc and click Download the Arduino Software.

Next you need the source code files (currently nine files with extension .ino) in
a directory with the same name as the main project file (excluding extension), 
which is currently SimpleSNA_WA5BDU_1r9_rev2r62.ino but will change as revision
numbers prgress.

Doouble-click on the above file in the directory and the IDE will open with the
file loaded.

Make sure the USB cord is connected between a USB port on the PC and the USB
port on the Arduino.

Under Tools in the menu bar, under Board select UNO.
Under Tools in the menu bar, under Serial Port, select the desired port.
(Note that in the lower right of the IDE, a message will show what port the UNO
 is connected to.)
Under Tools in the menu bar, under Programmer, I have selected AVRISP MK II (I'm
not actually sure we need to select a programmer, but this works for me.)

Everything is ready.  You can do a test compile of the program by clicking the
leftmost button of four below the menu bar, it has a check mark in it. It shows
"compiling sketch" and a progress bar and after a short time if there are no
problems it says "Done compiling" and gives a message saying the Binary sketch 
size and the maximum size allowed.

To actually send the program to the Arduino, you click on the next button, second
from the left, it has an arrow pointing right.  This time it repeats the compile
just like it did above (the above compile was optional) and after it is finished,
it says "uploading ..." in the message area.  Cross your fingers, if you have the
right serial port and no port conflicts, it eventually says "Done uploading" and
that means it worked!

By now your Arduino has started the program but everything scrolled off screen
before you could get a terminal program started! Start a terminal program.  One
option is to use the serial monitor in the IDE, by hitting CONTROL-SHIFT-M. Some
terminal programs automatically restart the Arduino by cycling the DTR line.  This
one does that, so you'll see the menu. Otherwise, you may need to reset the Arduino 
yourself.  Or hit '9' and the menu should re-display.
