Re: Can you identify this? (Rediffusion Frequency Translator).
Jeffrey's added:
Quote:
This never was a standards converter. It was simply a modulator that
took a 405 line video signal and produced an RF output on Channel 1.
The original Rediffusion box was a UHF 625 line analogue receiver which
also contained a Rediffusion HF modulator. The box was made so that
Rediffusion customers could still use their TVs when the Rediffusion HF
wired service was discontinued. I modified the HF modulator to run on
Channel 1.
In 1989 there were no low cost standards converters available. Just a
few ex BBC and ITV converters for the few lucky people who had them or
optical (point a camera at a monitor) for everyone else. The first
affordable converters, the Dinosaur and the Pineapple, were made
available c1993.
