Roy:

I just went through this on the K2 I'm building so I'll quote the
errata that I have from the Elecraft gang.

This is a mod to the VFO / ALC circuit.     It prevents a VFO buffer
( RF-U3) overdrive condition that may occur in some K2's when
switching to 17 or 10 meters.

C 154       old value   270pF                  new value     100pF
( 101 )
R 10                          1K
470 ohm
R16                            10K
100K
D8                  This is an add-on to the bottom of the board.
1N4148     ( cathod to the source of Q18  =     anode to ground.

I'm currently building K2 # 3951  and all these changes have been
incorporated into it and the board.

Have fun man:

73      and have a great weekend
