

Turn the K2 upside down (if it isn't already), with the front panel facing forward.



Cut a 7.5" (19 cm) length of RG174 coax cable. Remove 7/8" (22 mm) of the plastic jacket at one end,

and 1/2" (13 mm) at the other. Separate the braid from the center conductor at each end using a small,
pointed tool. Then unweave the strands. Be sure to remove all broken strands, which might cause shorts.



At the long (7/8" [22 mm]) end, cut away about half the strands, then twist together and tin those that

remain. Trim the prepared length of braid back to about 3/8" (9 mm) long.



At the short end, cut off all the strands. Cover the exposed braid with 1/2" (13 mm) of heat-shrink

tubing. Shrink the tubing using a high-temperature heat gun or a match (keep flame 1" away from tubing).



Strip off 1/8" (3 mm) of insulation from the center conductor at each end. Twist and tin the strands.



Place the coax cable as shown in the drawing below. The end with the longer center conductor will

terminate near 8-pin connector J13, which was installed earlier on the top side of the board.



At the J13 end, solder the braid to the indicated pad of L4 (ground).



Solder the center conductor into the hole just left of J13 pin 6 (labeled "X" on the board), or, if your

K2 s/n is 2999 or lower, to pin 6 of J13 itself. Count the pins of J13 carefully. The round pad is pin 1.



At the other end, solder the center conductor to the "RF" pad on the board, or, for K2 s/n 2999 and

lower, to the pad of R66 that's closest to the front panel. (Remove the KNB2 module to locate R66.)



To keep the coax cable in place, use a short length of the green-insulated, solid conductor hookup wire

as a retainer. Solder the wire in the position shown, using only the two indicated pads. These two pads are
already connected together on the top side of the RF board. Do not use any other pads.
