Dave >>Thanks very much for the APC rundown. I don't believe the model I have has the Line-R capabilities you describe so I'm going to look into an upgrade in the future because it sounds very useful.<< When you do get around to upgrading I'd suggest you check out Buy.com. I was really impressed with their prices. Here's a few examples: Model..................List.......Dealer Demo........Buy.com APC Line-R 1250........$269..........$150............$98.85 APC Back-UPS PRO 650 S.$379.99.......$191.78........$221.95 APC Smart-UPS 1000 Net.$679..........$404...........$394.95 Keep in mind the Buy.com prices change daily.

Dave, [electrical field induced monitor variance] I recently had an experience with this you might find interesting. I arranged to have my ducts cleaned. So the guy comes and, since I resist an innate tendancy to hover, plugs in his equipment without my supervision. He has a BIG vacuum as well as an air compressor sitting in the back of his truck 15-20' away from my monitor - and one of them is plugged in on the other side of the wall from my monitors. Different circuit, same wall. When he fired up those fairly large electric motors (magnets spinning in electric fields) I got a fairly dizzying set of waves on my monitors. I had him plug in elsewhere and things got better but I was still getting interference from the electric fields - I think. I suppose something could have come thru the breaker bus but I do have APC Offices on seperate 20A circuits so I am guessing the interference was mainly due to broadcast EMI. I was fortunate, of course, as the source of my EMI physically left. <g> But the proximity of your AC equipment and the route of the AC line(s) directly hooking into those motors may be relavent. An additional EMI source I haven't seen mentioned here in my less than exhaustive review is bricks. The power-bricks are transformers/inverters/EE-game-players and if they aren't properly shielded can generate fields. I've got a big one from my satellite receiver that can really make a mess of a perfectly good monitor if it is just a few inches too close. My attempts to fabricate a quick fast and dirty home grown shield didn't pan out, so I just moved it further away. jmho, I'm only knowledgable enough to be dangerous - certainly no EE expert. Good luck, Paul - 300 posts behind and LOSING ground. <g>
