As Ed pointed out - it appears that in military speak - W/T was also used in a different context: to describe the electrical bonding of the metal components of aircraft and vehicles in order to lessen interference.

Some military vehicles had screened ignition systems , so maybe this was another reason for the W/T marking.

I have seen the following described in many older publications:

R/T = Radio Telephony (voice communication)

W/T = Wireless Telegraphy (CW mode: Morse)

So it depends on whether you say: Toomartow or Toomaytow
