Thanks for the quick input. Carl/Ron, my noise seems to be only "phased" 
by the use of DSP NR. The blanker seems to have very little effect. Most 
of my sources are wideband hash from switching supplies (LV lights) 
running through-out the neighbourhood. The PRO2 DSP nr seems to be best 
at cutting a hole in it however I am having some very encouraging 
results using Linrad processing the audio output of one of my Omni's. 
This software is really quite spectacular (once configured), however you 
need to dedicate a seperate outboard PC running Linux.
It sounds like the O2 would be the equal to the PIII's NR however I 
appreciate hearing others comments.
If, as I suspect, all elce being equal the O2's receiver performance 
would likely make the decision for me. Initial software growing pains 
don't concern me given the vast potential offerred by the equipment.

Cheers es 73!
