Thinking contemporary burst transmissions would be more than time compressed CW.

High-Speed Encoders were the thing though is WWII and early cold war.  

Both limited technology and physically preventing the opposition in gaining technological/cryptographic advantage if the device was compromised made high-speed encoders the thing back then.

Thinking usage tapered off by the 1970s except for countries without access to improved technologies.

You can find lots of interesting background on these topics at the Crypto Museum website:  https://cryptomuseum.com/

Another resource is: http://www.militaryradio.com/spyradio/

Be aware that these websites, especially anything from the 
Volume 4 of the "Wireless for the Warrior" book and suplements are a rabbit
hole that will quickly become a time sink.
