K2: K2KSB2XTLS installation question

[John Shadle]

Hi,
I'm trying to finish up my K2 and am preparing to install the
K2KSB2XTLS mod. I understand where these crystals go on the KSB2
board, but am trying to figure out which crystals I remove from the RF
board. Looks like probably X7-X11, but that leaves me with 2 extra
crystals for the RF board. Where do they go?

Thanks in advance.

John,

Put them at X5 and X6 which are the 2nd Xtal Filter crystals.

BTW - if you have the original 2.1 kHz KSB2 filter width and want to
change it (using the KSB2CAPKT or your own capacitors), the time to do
that is after you remove the crystals from the KSB2 board and before you
put the new ones in - it is just easier that way.

Will you make it to the RARS hamfest tomorrow?  If so, look for me!
