Mark,
The resistance checks for these pin pairs should read > 100K ohms.
Infinity is a good number (and is greater than 100K ohms).
So, I believe you are in good shape. These are expected readings.
I would proceed with construction and I believe you'll find the board
is working.
If this isn't the case, of course, drop a line to the list or to me directly.

PS I just built one of these this month and had the same readings.

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
