[Elecraft] Building the XG-3

[Dr. Dan Swartling]

While building the K1, I had to come up with a signal source for alignment 
on 30m and 17m. The Norcal tuner upper for 30m (10116 kHz)  works great as 
a signal source, but I had to resort to a noise generator for 17m.

So I figured I could build myself an XG-3, the WARC band signal generator. 
I ordered another XG-2, and replaced the 20m, 40m and 80m crystals with the 
following:

X1 - 24906 kHz (12m)
X2 - 18096 kHz (17m)
X3 - 10106 kHz (30m)

I could have used the 18100 kHz crystal left over from building the K1 for 
X2, and the 10116 kHz crystal stolen from a second Tuner Upper kit for X3. 
I purchased the crystals I used from Expanded Spectrum Systems for $2.55 
each. It seems to works just fine!

The last thing to do was place little labels over the silk screened numbers 
on the board. Put a "12" sticker over the 20, a "17" sticker over the 40, 
and a "30" over the 80.

One final sticker - place a XG3 WARC sticker over the XG2 on the board.

If I am not the first to do this, then I apologize for the waste of 
bandwidth. Otherwise, feel free to build your own or bug Eric and Wayne 
into making this an official kit.
