"... being free of the need to minimize frequency slide - the bane of radar magnetrons"

Which leads to a BTW. One of the advantages of "superior" US/UK electronics technology was the "axis" gave up on magnetrons and stuck w/ necessarily low power klystrons. The soln. was to lock the receiver freq. using intentional leakage from the outgoing pulse; like synchronous detection?

bc, recently learned why it's the klystron gallery instead of the magnetron gallery; BTW, is there a way of synching magnetrons?

Klystrons are not necessarily low power devices.

One early approach to reducing mode hopping of the multicavity magnetron,
was to provide a twin transmission line to each side of all cavities.

A probably apochryphal story about the Axis effort to develop magnetrons:
early magnetrons returned a healthy enough fraction of the circulating
electron spokes to the cathode, to necessitate turning off the cathode heater.
An air radar that fell into Axis hands when fired up for magnetron tests, fried
its cathode because the cathode heating was maintained under power.

Brian Whatcott Altus OK Eureka!
