There is a GR group on Yahoo but its pretty quiet.
I joined when I started restoring one of the GR early synthesizers a 1161A, the a 1115A oscillator (the one where the dewer got destroyed in shipping). I have one of the tuning fork units, it is in very bad condition but cost me $1 at a swap meet. -pete On Tue, Nov 3, 2015 at 12:00 PM, Tom Van Baak <[email protected]> wrote: > 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.
