[Hallicrafters] Old equipment is fun/accurate.

[Waldo Magnuson]

Hi,
    A few days ago I mentioned buying a WW II Signal Corps BC-221-AK 
(a.k.a. SCR-221-AK) Frequency Meter.  I cleaned it up some (tube pins, 
contacts, case) and have been "evaluating" it.  When I set it to 2.500 
MHz it zero-beats exactly with WWV.  When I couple it to my HP 606A 
signal generator and zero-beat it on "operate" (for checking 
transmitters) it reads 2.50001 MHz on my HP 5328A Universal Counter.  
I'd say the BC-221 is as accurate as a lot of the modern equipment 
especially considering it's birth date (located inside case) is April 
20, 1944.  It's fun.
