37. Can you listen on the wireless alarm frequencies?

[-pull@shoot]

Do you have a receiver who capture the wireless alarm frequencies and
did you pay attention to the numerous transmitters who generate
"permanent" transmissions on those frequencies?

For example (only a very small sample):
 Listen to you car key transmission who operate on 434 MHz and see if
it is a "burst" or a permanent transmission..
 Very informative..
 Most car keys have permanent transmission when you keep the button
stroked and by consequence disturb wireless alarm systems.
 Do your wireless alarm system detect it? No of course, it would give
numerous false alarms.
