Sam, No "gotchas", but on the RF board, solder the grounding leads low on the crystals, and ground them on both sides. On the KSB2, consider also grounding the crystals near the base. That is possible if you mount the crystals one at a time - X4 first, then solder its ground wire - after that, X3 and X5 can be mounted and their ground wires soldered near the bottom. Then you can install X1, X2, X6 and X7. You then have only 2 ground wires to work with, so bend one ground wire around the base of X2 and X1 and solder - do the same for the other ground wire and X6 and X7.
The result will be a slightly better OP1 filter. If you did not follow the description above, that is OK, just solder to the top of the crystals. There is a small improvement, but not enough to 'write home' about. 73, Don W3FPR Sam Morgan wrote: > My next project is to install the 14 crystals in the K2KSB2XTLS package > ============== > K2KSB2XTLS > Matched Filter Crystals (14) > For existing K2 and KSB2 combinations. > ============== > > any one have any pointers, gotcha's, or other comments about this mod > they would like to share before I get the iron hot? > > TIA > > _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
