the Pixie is a crystal-controlled direct-conversion
transceiver, in a rather rudimentary but quite functional
form. The interesting quirk is that it uses the final
output transistor as the receive mixer.
Clearly this may take a lot more coaching than is practical
on a forum such as this, but I'll give it a go and try
to keep it short...
First I would go through the parts list and identify
each part, and which symbol it corresponds to on the
schematic. Hopefully you have a book that shows the
different symbols (resistor, capacitor, transistor, etc.)
Make a copy of the schematic and lay each piece on it
over the corresponding symbol. Fortunately there are
not a lot of parts, but you will have to match the part
values and types.
Next, look for some obvious clues for parts placement.
I expect the audio amp is an 8-pin DIP IC, and there
should be a set of 8 holes on the board that it fits.
If the board isn't marked, you will have to figure out
which way it goes in the holes. Look at the schematic
and see which pins are grounded, then check the board
wiring - the ground trace should be quite obvious.
Stick the IC in the holes and bend a couple leads to
hold it in place (DON'T solder it yet!)
The transistor holes may also be obvious, and if the
final is in a TO-39 case there shouldn't be any ambiguity
about which way it goes in. If the oscillator uses a
transistor in a TO-92 case, however, the leads will be
in a straight line, and (just like the IC) you will
have to figure how how they go. There may be some
clues for other parts, such as hole size, lead spacing,
Once you get the obvious parts in, pick a pin that you
can identify and see what parts are connected to it on
the schematic, then look at the copper traces on the
board that go to that pin. Some parts will be easy:
a capacitor to ground, for example, will mean looking
for a grounded hole that is spaced to fit the part. A
second lead on the same pin, then must belong to the
second part. Commonly parts are layed out neatly
parallel to the board edges - if that seems to be the
case with your board, it will reduce the number of possible
ways a part can be installed once you find where one
end of it belongs.
From there it is like working a jigsaw puzzle: sometimes
you have to play "what if" games. (Here it helps to keep
track of which parts you are sure of, and which you are
just trying in place to see if that solution works.)
Remember there will probably be holes in the board for
the output and power connections.
Fortunatly the Pixie is not a big kit, and you shouldn't
have much trouble figuring out the parts.
Or, if you don't feel up to QUITE that much of a
challange, here is a web site that has a lot of Pixie
information, including a photos and tutorials.http://www.qrpp-i.com/pixie2.htm
But it might be fun to try your hand at figuring out
the parts placement first!
