And so we embarked on the final month of our course. We were conducted to the Type 80 Laboratory found alongside a room marked "Type X". What that room contained we never did find out : the Type 80 was rated as "Top Secret" so the equipment in there must have been exceptionally esoteric. ( I have discovered recently that the Mark X version of IFF was new just about then, so perhaps it was that?)

The Lab contained, surprise surprise, a modulator cabinet and a transmitter cabinet, alhough both of these were very much larger than the Type 13 equivalents. A large grey object looking like an electric motor stood on a low plinth, and another cabinet contained a huge glass envelope with a dozen curly wires coming out of its top. The walls of the room were covered by huge oversize black & white photographs of external views of the radar, and we were amazed at its size. Again we were disappointed to learn that we would not see the real thing until we arrived at our postings.

The Type 80 we learnt was the last word in surveillance radar: its range and precision were unprecedented and were second to none in the world as the design had only commenced but five years previously under the codename "Green Garlic". This began as an experimental lash-up at the RRE of two Type 14 reflectors bolted end to end! Not that we ever allowed to see what an operator would see on his console, we just had to take the instructors word for it. But as the various parts were explained to us we realised that it had to be true and we were all very impressed at the advances in design from Types 13/14. Who would have thought that a magnetron could be watercooled for instance, as surely water and 32000 volts ought never to come in close proximity? So duly impressed we buckled down to getting everything into our heads, flattered to be entrusted to do so.

A month later the days for the 'boarding' and theory papers duly arrived and in due course again we found that all of us had passed. That evening we stitched onto our sleeves the single inverted stripe and signals flash which denoted our new exalted status of Junior Technician. Our Locking days were virtually over. That weekend I went home on my motorbike and returned by train and on the Monday we were paraded to hear where we were to be posted. As far as I remember not one of us was disatisfied, each was to be just about as close to his home as could be arranged, although that could mean a hundred miles or more for some. Dave Flux was content to be going to Beachy head despite that Ventnor would have been very much closer.He told me that Ventnor had Type 54 radars, the 200 foot tower mounted low looking variety of Type 14 but equipped with a dish reflector to give a "pencil" beam, which he could see at Ventnor from Southsea promenade, and he was jolly glad that it would be me and not him climbing up to them on a daily basis. None of our group cared to overindulge in drink, but I suppose that we must have had a celebration party of some sort, probably in the NAAFI and probably more of a wake than celebration, and it is a memory which I cannot recall. It certainly would have been a sad occasion for me as I had enjoyed the close company of all those in our group and I would miss them and.......all the while the prospect of those wretched 200 foot towers worried me.
