[Elecraft] confused with all mods k2

Hi John:

Somehow, I just saw this message from you, and I actually saw responses to 
it before I saw the original...

Mod's I'd suggest warranting your consideration:

   K2 2nd Xfil SSB Mod (KI6WX version), I can supply if
      you can't find it.

   K2 Walking VFO mod - But ONLY if you don't have the
      firmware version which fixes the problem AND if
      you don't plan to upgrade to that firmware version.
      Unfortunately, I do't have the info telling which
      firmware rev. fixes the problem. You might drop a
      note to Wayne <n6kr@elecraft.com> to find out if
      you already have the required firmware version.

   If you are a dyed-in-the-wool CW operator, you might
      want to consider adding the CW Xtal grounding mod.
      This mod moves the ground wires on the CW filter
      xtals from the top of the xtal cans, to the bottom,
      and adds a second ground to each xtal as well. Helps
      to reduce the amount of signal which 'sneaks' around
      the xtal filter and shows up as reduced ultimate
      signal rejection.

   Dave, G4AON, suggested changes to the capacitors in the
      higher band filters. This is generally NOT required
      US-based operators. However, it is suggested for
      European ops. They have a LOT higher levels of short-
      wave broadcasting stations over there.

   If you happen to have what appears to be a dirty AF Gain
      control... scratchy when you turn it, and especially
      down toward the low end of the AF Gain range, then the
      fix for the Noisy AF Gain control is worth adding, but
      not required if you don't have the problem... it can
      always be added alter on.

The KSB2 is a pretty closely packed PC board, so exercise EXTRA care when 
soldering on this board.

The "Rev C" you see there applied ONLY to the revision version of the 
MANUAL, not the RADIO itself! You have Rev A PC boards in your K2.

Hope this helps.
