K1-4 -- filter board resistance checks trouble

KB3OKS - Mark
Hello all,

I've just finished constructing my K1-4 filter board, and I'm failing
three of the resistance checks which are all reading infinite
resistance on my DMM:

  OK -- P1 pin 1, P1 pin 2
  XX -- P1 pin 3, P1 pin 4
  OK -- P2 pin 2, P2 pin 4
  XX -- P3 pin 1, P3 pin 3
  XX -- P3 pin 8, P3 pin 6

... all others are OK, including all tests across U1. Meter looks ok
  and is reading 0.1 Ohms when probes are touched together.

  Thanks very much for your time,

  73,

  Mark, KB3OKS
