You do have a point about the batteries. I did see that it was revealed in a later post that his main Skywarn (ARES? I forget which) repeater is a MastrII, which I don't think lends itself well to run on batteries. The reason I suggested that size UPS, was to move out of the junk consumer grade UPS' that I don't think should be in a repeater site. Besides, think of the runtime with a UPS a large as that!

Also, does the original poster "own" the radio room? If not, he probably can't dictate how much more space he takes in the place. > Your IRLP computer could be powered with a 1500 watt or better UPS. > This should allow sufficient runtime, plus the higher capacity should > get you out of the cheapo consumer grade UPS category. As Eric A 1500W UPS is overkill for a 100W load. -- Kris Kirby, KE4AHR <[EMAIL PROTECTED] <mailto:kris%40catonic.us> us> But remember, with no superpowers comes no responsibility. --rly
