It was raining heavily. I was sound asleep at about 2AM when there was a
really violent KA-BOOM. It propelled me out of bed and woke me enough to check the house for lightning damage (none) and to switch my antenna to a dummy position (yes, I know this does not do much good, especially after the fact). You know those "gift bags" (looking like a small shoping bag) that play tunes when a certain spot is squeezed? They usually play "Merry Christmas" or "Happy Birthday". One of these bags was in the bedroom, and had not been touched for months. It started playing (without being touched) just after the KA-BOOM. A second major KA-BOOM thunder/lightning happened about 10 minutes later. The bag started playing again. Both times, the bag played a normal cycle of the tune and then quit. There was no damage anywhere in the area and my Orion seems OK. The OT question is what kind of antenna effect (in the gift bag) would activate it? While it was raining heavily, there was no sense of heavy humidity in the house. No other electronics were affected, as far as I could tell. Bill W2WO |

I was given a RS color computer years ago after it had been on the receiving end of a lightning strike. Already having one of these computers I proceded to check it out by replacing the chips in my computer one at a time with the ones in the fried computer( I know, not very smart). Well at the the end of all the chip swapping my computer still worked. Power supply on the damaged computer checked OK. A closer inspection of the circuit board showd that some traces underneath the processor chip had ben vaporized. Repairing these traces yielded a working computer. How the lightning burned out these traces without frying the rest of the computer was beyound my understanding. Jimmie |

I had something related happen to me. We have a Teddy Bear that sings "We Wish You a Merry Christmas" for 20 seconds whenever you press a button on it. We don't take out the batteries before stowing it overhead in the garage. In March, I was experimenting with a 40m wire antenna draped over the garage roof. Do I have to tell you what happened whenever I keyed up? (Eventually, I climbed the ladder and took out the bear's batteries.) "Sal" |

Jimmie guessing a large and fast ammount of lightning induced current traveld along the ckt trace it got hot and fried creating the open voltage no longer could pass and so never reached the other parts ie chips etc so prob by luck you had enough current to damage the trace dosn't take much, but not enough to arc over and contine damage |
