For what it's worth, my pager (a Motorola Bravo (Plus?) using a frequency of 152.240 MHz) cheerfully receives pages while inside my microwave. (No, I didn't turn the microwave on. :) What that implies about the shielding capabilites of my microwave (and the safety of its continued use) is beyond my knowledge of RF and microwaves. I have some idea (please correct me if I'm wrong here) that shielding effective for energy at one frequency (like that of my pager) may be ineffective or less effective at another (like the frequency of microwaves). I'm intrigued (and alarmed) at the idea that it's possible to disable pagers via remote control. While I'll admit that there's some wee utility in being able to make sure nobody can use my pager if it's lost/stolen, it's sounding, from the posts to the list, like it'd be possible to disable many folks' pagers, were some miscreant so inclined. I know of pagers being used by police, fire department, search & rescue, private/campus security, and medical folks; if someone put some time into the "kill all the pagers" thing, it could be pretty damaging. Then again, knowing that, if I swiped somebody's pager, I'd probably just remove the battery for a few days, and hopefully miss the "stop working now" signal. I'm curious, though, how long the battery would last - my pager has a single AA battery, which lasts about a month. On average, a pager in the "find this pager" mode would have a single half-discharged AA battery to power its transmitter; and that transmitter would be sending its signal without benefit of any sort of external antenna. My very limited knowledge of RF propagation makes me think it'd be hard to get much range or duration under those circumstances. I'd be interested to see this thread move over to comp.dcom.telecom - there might be more folks who know about pagers who could comment. This is interesting, but frankly I'm still pretty skeptical. -- Greg Broiles greg@goldenbear.com Golden Bear Computer Consulting +1 503 342 7982 Box 12005 Eugene OR 97440 BBS: +1 503 687 7764
