[Elecraft] High Accuracy TCXO

[Eric Swartz WA6HHQ - Elecraft]

The 1 PPM TCXO does give you 1 PPM accuracy over temperature. (Versus 
the 5 PPM standard TCXO.) In fact, its a bit better than that over the 
commercial temp range. Nothing has to be enabled by the user. Its just 
more temperature stable than the 5 PPM part.

We have plans to add firmware correction to get it to 0.5 ppm, or 
better, by using the internal temperature sensor on the front panel to 
do piecewise corrections to the oscillator over temp. That will be 
finished after Wayne gets the 2nd RX out the door. :-)
