So you invented an antigravity drive based on microwaves? :D :rolleyes:

I, too, am interested in what he is using it for. The magnetron cavity is tuned to a specific frequency (in the case of a microwave ovens magnetron..its the natural frequency of water). So for him to not use it for heating is....interesting, And probably means that that magnetron was never intended for a microwave oven. |

it is tuned to 2.45GHZ just like a microwave oven. however supplying different voltages to some magnetrons can produce diffrent frequinces

OW! :ahh: i think he needs to go back to chip sweeper status in the machine shop ;) i have done stupid stuff too, gotten cut on and endmill, ripped my thumbnail with a tuning-fork-looking skate wheel folder, .... but watch yourself around hot stuff :) -Q |

Before we get too crazy here, the microwave used for communication is a relatively low power device connected to some high gain, directional antennas. Most are not harmful unless you choose to climb the tower and stand in front of it. Radar installations create more power than these in the picture. For those of you who are RF inclined, the brass cylinder sticking out the top of the magnetron is actually a 1/4 wave antenna used to couple energy into the cavity of the microwave.
Please Tytus, tell me you were careful when you extracted the device from an oven. There is some really high voltage capacitors that can hold a charge for quite a while that are connected to the magnetron. |
