Wait a minute - he said the new xtals were 36 kHz off frequency @ 147.105 MHz. That's a long ways off, more than you would normally be able to "warp" them with capacitance. I'm going to go out on a limb here & say this has nothing to do with having the elements "matched". FWIW, I've rerocked dozens of GE xtal modules & ICOMs over the years & never had a problem getting the xtals on frequency. Temperature stability is another issue; I take a different approach by removing all compensation in the module & temperature-stabilizing the xtal itself. Bob NO6B
