Hi

If you don't want to scratch build a noise generator (it is a fairly easy=
 circuit, in fact the first one I built was Manhattan style) I still have=
 plenty of the kits. =20

The kit includes a 1 1/4 x 2 inch silk screened and solder masked fibergl=
ass circuit board, 3 2N3904 transistors, 5 resistors, 4 capacitors, a 9V =
battery connector and instructions. You provide a small box, a switch and=
 a BNC connector (available at Radio Shack). If you don't want to get thi=
s fancy you could just connect the 9V battery and a piece of hookup wire =
to the output and ground and stick the stripped end into the K2 antenna B=
NC and ground terminal. The circuit is very similar to Tom's. I use the b=
ase-emitter junction of a 2N3904 as a zener  diode, some resistor value c=
hanges and I added a .1 UF cap to decouple the supply. The instructions f=
or use are on the Elecraft site under builders resources and on Tom's web=
site listed below. This has been a very popular kit.

Price for the kit is $15 check or money order

Hi Folks:

Ron D'Eau Claire, AC7AC, just sent me a copy of a PDF he's prepared to =20
assist builders who wish to construct their noise generators, but who don=
't =20
have a PC board. Apparently, Ron (like myself) has been receiving a numbe=
r =20
of queries, asking about possible construction schemes for this small pro=
ject.

Ron's PDF is now resident on my web site (Gawd, I HOPE I can type the URL=
 =20
correctly THIS time...!) at:

   http://home.earthlink.net/~n0ss/download.html

The file is down about 1 screen from the top of the page, under "General =20
Elecraft K1/K2 Building Files".

PLEASE READ (AND FOLLOW) THE INSTRUCTIONS FOR DIRECTLY DOWNLOADING THIS =20
FILE TO YOUR PC, RATHER THAN DOWNLOADING IT TO SCREEN FIRST.

As always, if this URL fails (as all too many have in the past 24 hours, =20
sigh!) drop me a note.

73,

Tom  N0SS
