Glenn, Tilt the board at about a 45 degree angle so gravity will help solder flow, and more importantly, so you can see what you are doing. Use a large flat area of your soldering tip on the side of the crystals to provide a better heat path and heat until the crystal case itself melts the solder. I use an 800 degree F. iron to accomplish the soldering in about 3 seconds.
Yes, solder the xtals on both sides and as low on the xtal sides as you can manage - it provides a lower impedance path to ground resulting in a filter with a smoother shape and better stopband attenuation. 73, Don W3FPR > -----Original Message----- > > 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.
