Yup, that's normal of all those older rigs that incorporated seperate 
transmitters and receivers.

It wasn't until the 60's, with the advent of "vox" when 'break-in' CW 
came about.  I -think-
one of the first rigs to do this, that was still a seperate machine from 
the receiver, was the
Hallicrafter HT-37.

Revolutionary, those 60's. :-)
