I'm using a direct probe. The 815 has a 50ohm input which should be a
match to most points in the ubitx. At least a close enough match to not
directly affect the circuits operation. I suppose I could use a 10x
scope probe but I'm not sure that would make much difference.

Hi Tim,
I'm interested to know how your connecting your SA to the circuit,
from my recollection the majority of SA equipment has a 50 ohm input
impedance, an input impedance that low is not conducive to hanging a
probe off the circuit at any convient location.?
