This is interesting. I think Geo reported his Mineoro will beep when he pushes the transmitter button to make a garage door open. When we check the garage door button transmitters, we find they are made to work at frequencies from 300 MHz to 400 MHz, and can be different in different countries. Even in the same country we can see a lot of different transmitters that can be used. For example, in the USA, the Genie garage door opener company will sell you any of these frequencies:
290, 295, 300, 305, 310, 315, 320, 325 or 390 MHz
And there are a lot more frequencies for garage door transmitters used in this range. If Geo sees his Mineoro locator beeping at a garage door transmitter, then maybe it is sensitive to short bursts in the 300-400MHz range. Or maybe it is picking up some modulation from this burst. Maybe it depends on the digital code that is programmed to open the door.
Here is another experiment to try:
Get a piezoelectric cigarette lighter that makes a spark when you light it. Let's see how far the Mineoro can detect this spark.
