[Elecraft] 10 MHz external reference - GPSDO

[Don Wilhelm]

Note that 2 Hz refers only to the reference oscillator which is close to 
49,380 kHz.  That is about .04 ppm, or about 10 times greater than the 
specification for the high stability (optional) TCXO.

The frequency accuracy at HF will also be .04 ppm - at 10 MHz that is 
0.4 Hz, at 20 MHzit is 0.8 Hz and so on.
