Hi all i have found a couple of units and i was after your help to see what aircraft they were used in and to see if they can be used in our Canberra projects(i fear they wont) any help would be great .
The top one has this written on it…….Decca control unit type 991
The bottom one has control radio set (for ptr.170) written on it.
All the best Matt:o

The “oven” marking presumably means a crystal oven to keep the crystal at a constant temperature to prevent it drifting off frequency.

The PTR 170 is a 12-channel UHF radio with a built-in ADF homing facility, although I believe there was a version without the homer. It’s of late 1960s/early 1970s vintage.
I don’t have a comprehensive list of aircraft that used it but I do know that it was fitted to a number of the export Hunters, including mine, as a standby set. It was also fitted to some helicopters (e.g. Wasp, Sea King, Wessex), late Chipmunks and other “second line aircraft”.
Being a relatively basic set if it was fitted to Canberras it would have been as a No.2 set I would think as per the Hunters.
Not sure that helps much!
