Hi, guys, I've ordered the 14-matched-crystal set and put the ones on the SSB board (big improvement!) and am almost done with the RF board crystal except that I've lost the instruction sheet that came with them (I think the xyl "cleaned" up after me and thought it was scrap :) and don't know which two crystals other than X7 to X11 get replaced. Any hints? Thanks! Joe, W2RBA
