Some of you know I spend as much time looking backward as looking forward: both ends of the precision time envelope are extremely interesting -- from chronometers and tuning forks -- to cesium clocks and masers. In particular I trying to restore and power up several old NL (Norrman Laboratories) and GR (General Radio) pre-quartz frequency standards/clocks from the 1930's. Can someone tell me if there's an active GenRad user group, web-forum, or mailing list on the web? In spite of a heavy shelf of General Radio Experimenter magazines, GR catalogs and GR manuals, I could use some help. Replies on- or off-list are ok. For those of you new to the 20th century history of time & frequency see mouth-watering specimens like: http://leapsecond.com/museum/gr1103a/ http://leapsecond.com/museum/gr1190a/ http://leapsecond.com/museum/gr676b-50kc/ http://leapsecond.com/museum/gr815b/ http://leapsecond.com/pages/old-genrad/ Thanks, /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
