[Skimmertalk] 192 vs. 96 Khz on QS1R

Hi Jeff, 


Performance measurements of communications systems must be 
based on statistical measures. Noise in the communications channel 
introduces many "tipping point" decisions that produce the results 
you're observing.

I have two identical QS1R feed with a splitter. One running 192 Khz and 
the other 96 Khz. It seems that I get about 1.5-2x the spots out of the 
96 Khz width skimmer with (as far as I can determine) exact settings. 
If I bump the 2nd one from 96-->192Khz, the spot rate is very similar. 
Wondered if anyone else has seen this and what may be behind it. 

Another pretty weird thing is with the two skimmers setup and running 
identically, about 2/3 of the time they will decode the same set of 
calls. And the other 1/3 of the time one **OR** the other will catch 
the guy, but not both.
