Building a K2. (Having great fun doing so!) Working on the RF board. At
the point of installing crystals X1-X11. These have one or two ground leads
each. Any reason not to solder the ground leads on the cases first and then
install the crystals? This would involve routing three or four leads
Jim,
That will work, and I have heard of some who did it that way.
I find it is easy (even in the close quarters with the R-Paks) to solder
the wires to the crystal cans after the crystals are mounted.
My technique is to solder in the ground wires (don't trim the leads on
the bottom of the

FWIW, I have always found it useful to scratch the surface of the
crystals and tin them prior to mounting them on the board. It clears
any tarnishing of the cans between time of manufacture and assembly and
makes soldering easier.

Hi,
For the moment I'm enjoying the construction of K2 number 5549.
Could anyone send me a picture of the crystals X7-X11 that are correctly
grounded?
The manual says the grounding wires should be soldered to the sides of
the crystals but on all the pictures I found on the net they are
There is an errata that says to put 2 grounds to each crystal. One to
the top, one to the side (or maybe one on each side? I believe the
change was part of the errata for the SSB module???
