CV89 interdigital magnetron
(related to CV79 which is a frequency variant).
This generates about 300mW at 6.3cm (4.76GHz).
The CV79 and CV89 were used
in Wireless Set No.10, which played an important part in the WWII D-Day
landings. This was a trailer mounted installation, using pulse modulation
to enable 8-channels (e.g. 8 phone lines) over a 50 mile (optical) path.
The associated receiver made use of the CV90. The
Mk. II version used two CV228 Heil tubes in the
transmitter instead of the CV79 or CV89.
