Hello Bern.
Old Buddy.
Real Radar Man here.
I am still regularly using a Decca 424 (It's six years younger than me, but older than the one in the Science Museum). It has a Decca-plot overlay on which I write headings and shopping lists with my chinese graph............plus I have to tilt my aerial, amongst other things. And, depending on which gives up first, I hope to be doing so for many more years yet, ATSSD permitting. We don't get many VFR customers, though, but they could try a PM for a run or three.........
