[Ham-Computers] Some probably dumb questions

Sun, 6 Apr 2003 20:19:19 -0400

There is no such thing as a dumb question, just dumb answers! 	

There is no law against being ignorant, but there should be for willingly
remaining that way. 	

Never be afraid to ask a question, even if you think it is silly. You can only
learn by asking, so ask away. If you are ridiculed for doing so, then you have
learned who is truly ignorant.

    If you can install an old style alarm system window bug on an 
outside window and this bug will false alarm during a thunder storm. 
(This thunder false alarm is one of the reasons window bugs were poor 
for security. They are a sensitive vibration sensing switch.). When the 
window bug trips due to thunder the radio and other hardware is 
disconnected from outside sources of lightning strikes.

good luck from Jim Brampton VE3 JIW
