There's so much lead in a battery, and it's so concentrated, that it's easy and economical to recover. The opposite is true for the solder. The whole lead-solder-in-electronics thing is due, ironically, to the relatively short life cycle of many electronic devices these days. I don't know about Europe, but here in the USA many people consider a 5 year old computer to be all but useless. I have found many completely working computers on the trash, discarded simply because they were old. Latest find was a 400 MHz PII Dell desktop, with 17" Dell monitor, 13 gb HD, 256 mb memory, Win2000, NIC, etc. Its next stop was the dumpster. How much lead is in that thing, I do not know. The ironic thing is that amateur radio equipment tends to have much longer useful life spans. Many 20-30+ year old ham rigs are perfectly usable today, particularly for non-critical applications. Even junked ham rigs are valuable for their parts, to restore others. btw, we have a similar problem with white-tail deer here. Back on New Years Day 2001 I bagged a doe on PA Route 202. Over $5000 damage to the Honda Odyssey. Fortunately nobody but the deer was hurt. We're overrun with them but the "Bambi factor" limits hunting. 73 de Jim, N2EY _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
