Another update because I have an unhealthy obsession to figure this out an be done with it.
I brought the 7100 back on Thursday and had it on the bench with 2 real CO lines plugged into it all weekend and the alarm logs are showing nothing, except when I tried to hose it up by tying the rings together with a resistor.
I took the same readings on my lines today as I took at the site and other than the loop current ma readings and the on-hook DC: Mine- 45 site-51.8 everything else was pretty much the same even the AC T to grnd were around 1.7xx. The ONLY big difference was that I could not pick up any AM radio stations no matter how many ways that I moved my arms around. "picture that in your head"
So whoever is still reading this war and peace size thread the question is:
Any thoughts on the AM radio coming over ALL the CO lines at the site. I did a mapquest from station to site and they run along RR tracks 5 miles apart and I'm guessing the aerial cable runs the same route.
