You have good advice from Fred K4DLL.
I have built a lot of gear and would not even think of keying an oscillator.

The trick is to make the oscillator run at essentially the same power level
whether it is oscillating or not. This means class A operation and you key
the feedback loop instead of the oscillator itself. That way the tube or
transistor has the same dissipation at all times.
It's a bunch of work to design and probably not worth it, but it *can* be
done. (Just kidding about the sissy part).
