Today I soldered the 6 MV209 varactor diodes and the 11 1SV149 's on the RF-board of my K2 #4654 According to the text on page 50 the varactor diodes should be pressed all the way down on the board to prevent stray signal coupling. The SV149 varactors may have a center lead that has been cut flush with the body of the device.

The center leads are clearly visible, about 0.5 mm coming out of the varactor bodies! The soldering islands for the two varactor leads have a very narrow gap, not more than half a mm on top of the board. The center pin can easily short against one or even both leads of the 1SV 149 's. I left them about one mm above the board.
