[Elecraft] [Elecraft-K4] Improved frequency accuracy with external reference

[Wayne Burdick]

For those using the K4 with an external reference:

Ken Long (N0QO) alerted us to an offset of about 0.1 ppm when the K4 was externally locked. 0.1 ppm is about 5 Hz on 6 meters. 

We confirmed this using a GPS-locked 10 MHz reference, and corrected the error. Accuracy is now in the expected range of about +/- 1 Hz on all bands, 6 m included.

This correction will be available in the next beta release.
