[Elecraft] XG50 warmup after initial run

[Don Wilhelm]

Mooneer,

I would not go so far as to say that.  Any stable signal generator needs 
some warmup time.  For instance my HP8640B is very stable - but only 
after about a 2 hour warmup period.  Everything inside has to come up to 
operating temperature, and it drifts until that occurs.
I would suggest at least a 15 minute warmup for the XG50, a half hour 
would be better.  At least I would be more comfortable with an 
assumption like that even if it is overkill.

I believe the 8 hour 'burn in' is a time to allow the XG50 crystal some 
'run time'.  New crystals will typically exhibit some initial change in 
frequency that does not re-occur - think of it similar to the 'break-in' 
period for a new engine - you don't have to repeat that every time you 
start the car, but you do have to let it warm up before it will deliver 
peak performance.

73,
