Transmitter Reciever TR9D

[Andy Saunders]

As Pieter says, and as I aluded to, I am surprised you have found a TR9D in a Fairey Battle.

The other odd thing is the 10A/104870 number (I think that should be 10D, perhaps?) Are you sure it is not 10470 - no 8 between the 4 and 7.

I dip my toe in this with trepidation but, after the introduction of VHF by the RAF, Army Co-operation aircraft used the TR9 to communicate with the Army? Might this give a clue?
