[Premium-Rx] RACAL DK-43 Tuniing Aid

[acyg]

Hello to all,

I have recently acquired a Racal DK-43 tuning aid.
A very nice item which works perfectly with any receiver with a 100KHz IF
output.

However being the inquisitive type that I am, I've been searching for a
manual and circuit diagrams for this unit, but to no avail.
Can anyone help in any way at all?

May I wish all a very Merry Christmas and Prosperous New Year...
With many premium receivers for the future.
