[Elecraft] [K2] Long term reliability with leaving radio on 24/7???

[Mike-WE0H]

Has anyone left their K2 on 24/7 for freq stability reason's? Or ran 
QRSS and can say how well it stayed put? Previously when I was running 
1750 meters, I used to leave my TS-440 on 24/7 for a couple years. It 
still worked after all that time running...hi hi...But what I would like 
to know is, would the K2 be expected to run say for a year straight 
without any issues? Of course no antenna would be connected when it 
shouldn't be...I have had it running for about 9 hours today and did the 
calibration a couple hours ago and the radio is dead nuts stable within 
1hz of what the reference oscillators here are which are calibrated to 
WWV. I haven't had the chance yet to let it come down to room temp and 
be turned back on and see where the calibration would be at. Anyone with 
experience in this stuff?

Many thanks,
Mike
