Re: Crystal calibrator / Frequency standard
Nice piece of kit Al.
Back in the late 70s, I made a calibrator, mains powered, 1Mc/s xtal osc, 7490 dividers and 1Mc/s, 100Kc/s and 10Kc/s outputs on a bnc.
In the early 80s, with a young family to look after, I had a clear out at a rally or two of stuff I no longer used.
Fast forward to around the year 2000, at a rally rummaging under a club junk stand I picked out a distinctive blue and white metal box with mains lead attached and recognised it. However, I couldn't figure out where I had seen it before though.
Then, I saw my own callsign in letraset on the front panel! I just had to buy it! 50p I think it was?
It now sits, pride of place on top of a box of radio items in my garage!!!
Despite this, I doubt I would ever part with it again though.
Rob
