Are the alarms indeed false?  Have you tried a second detector,  preferably 
not a Kidde Nighthawk?
 
It sounds like you have a detector.  Can it be moved/traded with your  
neighbor on a trial basis?

For the past year and a half my neighbor has claimed frequent  interference
to his Kidde "Nighthawk" Carbon Monoxide detectors. While we've  been able to
prove a few frequency/power combinations that definitely result  in false
alarms, a majority of the "alarms" occur when I'm not transmitting  at all!
The neighbor's claim is that my tower (and by extension, the yagi on  it) is
somehow 'reflecting' another signal in the neighborhood and causing  the
false alarms.

I've tried to explain the implausibility of the  claim, and even tuned
through the HF spectrum during some of these false  alarms, without finding
any signals that to me would obviously be strong  enough to cause them. But
the belief remains in my neighbors' mind that I am  the cause of the abnormal
occurrences in their house. My house is  experiencing zero false alarms
during the same period.

So the question  for the community: Is my neighbors' claim valid? How might I
go about helping  to prove (or disprove) it?
