Do these little guys use magnetrons??

not much for power....would this use some sort of tube??

Yes, they do. Magnetrons are both oscillator and amplifier and
frequency controller. They are extremely efficient at putting out a
very narrow pulse of very high powered RF energy. Any FAA long-range
radar site has another similar device on S-Band, the amplitron. It
takes the powerful pulse of the magentron and amplifies it into the
megawatt range!

The magnetron in our 2KW Raymarine is a tiny little thing with a tiny
little filament to hold down the power drain. Every microwave oven in
the world has a magnetron firing 50 to 60 times per second into its
cooking cavity. They are also dirt cheap, which is why the marine
industry loves them....(c;
