[time-nuts] Improving the stability of crystal oscillators

[Don Collie]

Has anyone concidered using a small Peltier pile to maintain the crystal`s 
temparature. I understand that these devices will heat or cool, so it would 
be possible to maintain the crystal temparature at , say, 25 degrees 
celcius, over a range of ambient temparatures
[perhaps 0 to 70  degrees]. There would be several advantages in this 
approach.
