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
