The W/T Set C Mk I was a Continuous Wave (CW) Wireless Teletype set intended for use at Divisions and Brigades. It consisted of two main parts, a reception set and a sender set. The sender was usually used with a 120ft aerial in two 15 ft. masts while the receiver worked with a basic single wire or other aerial. Also part of a complete set was an engine driven generator set (or "power unit") and switchboard.[1][2]

It has not been confirmed if Canada used this W/T unit as no documentation or images have been located to date. There is evidence that Canada used the Wireless Telegraph Set C Mk II.
