[Elecraft] K1 RF Board Prep for KAT1

[Don Wilhelm]

Tom,

As instructed in the KAT1 manual, refer to page 31 of your K1 manual and 
see if R39 is present.  If not, add it.  In either case, solder C76 
across R39 - one capacitor lead to each resistor lead.

Do the trace cut as shown in the diagram on page 8 - I can't describe it 
better than the pictures.  Install R4 as shown in the diagram.

You can make those RF Board changes at any time - except for removing 
the end of R36 - wait until you install the KAT1 for that part.

73,
