[Elecraft] XV50 question

[Don Wilhelm]

Jim,

I would have to ask the XV series designer, but he specified that those 
transistors be mounted above the board.  Likely for LO stability, and 
better separation from the ground plane on the board.

I believe it should work mounted the same way in the XV50.  If you find 
LO instability, then mount it down on the board.

If you scraped the paint from all panels where they contact the 2D 
connectors and the output jack, there should be little noise conducted 
to the inside of the transverter.

73,

Should I re-install it in the usual way (close to the board), or leave it. Also, can anyone tell me the reason for elevating it in the other XVs? That seems like a good way to pick up noise to me, but a lot of you have forgotten more than I know about this stuff...
