[Elecraft] K2 - grounding of RCVR filter Xtals

[Harvey Howell]

Hi Glenn. Here is the approach I used and it worked fine for me. I held each 
xtal in one of those extra hands devices that has several alligator clips on 
it. Then I put the ground wire in the other alligator clip and positioned it 
so the wire is on the side of the xtal then solder. I did it this way on the 
side of each xtal so when I put it on the board all I had to do was solder 
the four leads on the board and trim. The alligator clip serves as a nice 
little heat sink too.

Hi all

My K2 s/n 5361 is coming together nicely, up to now I've encountered no 
problems whatsoever.
I just installed the receiver filter Xtals X7 through X11 and now I've 
arrived at the point where these Xtals have to be grounded (page 53, last 
step).
The manual states that a special grounding technique is required for the 
grounding of X7-X11. Instead of soldering a grounding lead to the top of the 
Xtal housings the manual states that the grounding wires need to be soldered 
to the sides of the housings.
There are 2 grounding pads for each Xtal. My question is: is it absolutely 
imperative to use 2 grounding leads for each Xtal? I don't see too many 
problems soldering the leads near the outer edge of the PC board, but the 
soldering points at the opposite sides of the housings are awfully close to 
RP4 and RP5...
Any suggestions as to how I should go about soldering the grounding leads at 
those sides of the Xtal housings?

Thanks for any advice.
