[ARC5] SCR-274 calibration Xtals

[k1uhy at comcast.net]

I wouldnt bank on an almost 80 year old rock being forever accurate or even dead on from new. What was the original tolerance spec?

Just for fun, I decided to see how the magic eye transmitter calibration system worked in practice. 
It actually worked pretty well, but the resonance was at 3502 khz instead of 3500 khz ( marked on xtal) . Is this typical? 
BTW, does anyone have the 8000 khz xtal( I think that's what it's supposed to be) for the BC-459 to sell?
