[Elecraft] About a two-phase install of the KSB2 option on a modern K2

[Don Wilhelm]

Mark,

You can do any and all of the KSB2 installation and still transmit and 
receive CW as before.  If you remove W2 and W3, you can restore receive 
by placing a bent wire jumper from pin 1 and pin 3 of both J9 and J10.

Similarly, transmit can be made operational by installing a .001 
capacitor between pins 7 and 12 of J11 (or you can leave C167 installed 
until the last minute before the KSB2 is installed).

73,
Don W3FPR
