Re: Can you identify this? (Rediffusion Frequency Translator).
Here, just for completeness is the exact opposite of what you have there before it was modified.
It took the HF video and base-band audio from the switch on the wall or windowsill, demodulated the video then re-modulated it onto a UHF carrier so a normal TV could be used.
You can see the ubiquitous modulator can that was in most VHS machines back in the day.
I have at some point "borrowed" some components including the chip.
It fitted into a box identical to the Labgear Televerta, so that may be a clue to its maker, it only had a Granada stock-category label on it.
