[Elecraft] Ngen Wideband Noise Generator Mini Module Kit Problem

[Don Wilhelm]

Scott,

Those 4 "ARMS" of the MMIC are the leads.  Do NOT break the body of the 
MMIC, you will destroy it.
Find the one lead that is cut at an angle (that is the input) and orient 
it toward the center of the board.  If you cannot see the angled end, it 
is the lead closest to the dot on the body.  If there is a hole in the 
board, the body of the MMIC goes into that hole.
If there is no hole, orient the MMIC so the angled lead (or dot) is 
toward the center of the board.
Solder those "ARMS" to the 4 solder pads below.  If there is no hole for 
the body you have to press the leads down with a screwdriver to make 
contact with the solder pads, then do it.

No wires are necessary - just fill the holes on the solder pads with 
solder and solder the leads flat onto the board.

73,
Don W3FPR
