I am running a Yaesu 5000 150 watts to an inverted v with the apex at 85 feet fed with hardline. This only happens when I am on 80 meters, 3705 is where I was when the first call came in. So I can't figure it out nothing in my house or any other houses is effected.

Alarm systems are notoriously bad at RF susceptibility. Some use the AC 
line for signalling, many use dedicated wiring that is not twisted pair. 
Both make the systems sitting ducks for RF. Tell them to call the 
installer or mfr.

Microwave ovens have speakers?

Neither of these can be caused by anything on your end. If you want to 
be a good neighbor, study my applications note on killing RX noise, but 
in reverse -- that is, use the choke guidelines for the cables connected 
to the victim equipment, as close as possible to each piece of 
equipment. For that microwave, I'd use guidelines from my new Choke 
Cookbook.

Other comments. The earth is not a sump into which noise is pumped.
